Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EBS00QUU
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS0095K
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for On Board Diagnostic (OBD) System of A/T and Engine
ECS0095L
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
●
Be sure to turn the ignition switch OFF and disconnect the negative battery terminal before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MIL to light up.
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
●
Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
●
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.
●
Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM or
ECM before returning the vehicle to the customer.
Precautions
●
ECS0095M
Before connecting or disconnecting the TCM harness connector, turn ignition switch OFF and disconnect negative
battery terminal. Failure to do so may damage the TCM.
Because battery voltage is applied to TCM even if ignition
switch is turned off.

When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.

After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE”.
The DTC should not be displayed in the “DTC CONFIRMATION PROCEDURE” if the repair is completed.
Before proceeding with disassembly, thoroughly clean the outside of the transaxle. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.
Disassembly should be done in a clean work area.
Use lint-free cloth or towels for wiping parts clean. Common
SAT964I
shop rags can leave fibers that could interfere with the operation
of the transaxle.
Place disassembled parts in order for easier and proper assembly.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
Gaskets, seals and O-rings should be replaced any time the transaxle is disassembled.
It is very important to perform functional tests whenever they are indicated.
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
Replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to AT-12,
"ATF COOLER SERVICE" .
After overhaul, refill the transaxle with new ATF.
When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque
converter and ATF cooling system.
Always follow the procedures when changing A/T fluid. Refer to AT-398, "Changing A/T Fluid" .

PRECAUTIONS
[RE4F04B]
Service Notice or Precautions
ECS0095N
FAIL-SAFE
The TCM has an electronic Fail-Safe (limp home mode). This allows the vehicle to be driven even if a major
electrical input/output device circuit is damaged.
Under Fail-Safe, the vehicle always runs in third gear, even with a shift lever position of 1, 2 or D. The customer may complain of sluggish or poor acceleration.
When the ignition key is turned ON following Fail-Safe operation, A/T check (position) indicator lamp blinks for
about 8 seconds. [For “TCM Self-diagnostic Procedure (No Tools)”, refer to AT-60, "TCM SELF-DIAGNOSTIC
PROCEDURE (NO TOOLS)" .]
The blinking of the A/T check (position) indicator lamp for about 8 seconds will appear only once and be
cleared. The customer may resume normal driving conditions.
Always follow the “Work Flow” (Refer to AT-68, "Work Flow" ).
The SELF-DIAGNOSIS results will be as follows:
●
The first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.
●
During the next SELF-DIAGNOSIS, performed after checking the sensor, no damages will be indicated.
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:
●
External leaks in the hub weld area.
●
Converter hub is scored or damaged.
●
Converter pilot is broken, damaged or fits poorly into crankshaft.
●
Steel particles are found after flushing the cooler and cooler lines.
●
Pump is damaged or steel particles are found in the converter.
●
Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)
●
Converter is contaminated with engine coolant containing antifreeze.
●
Internal failure of stator roller clutch.
●
Heavy clutch debris due to overheating (blue converter).
●
Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:
●
The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
●
The threads in one or more of the converter bolt holes are damaged.
●
Transaxle failure did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.
●
Vehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.
ATF COOLER SERVICE
If A/T fluid contains frictional material (clutches, bands, etc.), replace radiator and flush cooler line using cleaning solvent and compressed air after repair of A/T. Refer to CO-13, "RADIATOR" .
OBD-II SELF-DIAGNOSIS
●
●
●
–
–
–
A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the A/T check (position) indicator or the malfunction indicator lamp (MIL). Refer to
the table on AT-49 for the indicator used to display each self-diagnostic result.
The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memories.
Always perform the procedure “HOW TO ERASE DTC” on AT-46 to complete the repair and avoid
unnecessary blinking of the MIL.
The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when
the A/T check (position) indicator lamp does not indicate any malfunctions.
park/neutral position (PNP) switch
A/T 1st, 2nd, 3rd, or 4th gear function
A/T TCC S/V function (lock-up).

Whenever an automatic transaxle is repaired, overhauled, or replaced, the A/T fluid cooler mounted in the
radiator must be inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can contaminate the newly serviced A/T or, in severe cases, can block or restrict the flow of A/T fluid. In either case,
malfunction of the newly serviced A/T may result.
Debris, if present, may build up as A/T fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.

LINE PRESSURE CONTROL
TCM has various line pressure control characteristics to meet the driving conditions.
An ON-OFF duty signal is sent to the line pressure solenoid valve based on TCM characteristics.
Hydraulic pressure on the clutch and brake is electronically controlled through the line pressure solenoid valve
to accommodate engine torque. This results in smooth shift operation.
Normal Control
The line pressure to throttle opening characteristics is set for suitable
clutch operation.
SAT003J
Back-up Control (Engine brake)
If the selector lever is shifted to 2 position while driving in D4 (O/D)
or D3 , great driving force is applied to the clutch inside the transmission. Clutch operating pressure (line pressure) must be increased to
deal with this driving force.
SAT004J
During Shift Change
The line pressure is temporarily reduced corresponding to a change
in engine torque when shifting gears (that is, when the shift solenoid
valve is switched for clutch operation) to reduce shifting shock.

At Low Fluid Temperature
●
Fluid viscosity and frictional characteristics of the clutch facing change with fluid temperature. Clutch
engaging or band-contacting pressure is compensated for, according to fluid temperature, to stabilize
shifting quality.

The shift is regulated entirely by electronic control to accommodate vehicle speed and varying engine operations. This is accomplished by electrical signals transmitted by the revolution sensor and the ECM (throttle
opening). This results in improved acceleration performance and fuel economy.

Control of Shift Solenoid Valves A and B
The shift solenoid valve performs simple ON-OFF operation. When
set to ON, the drain circuit closes and pilot pressure is applied to the
shift valve.
The TCM activates shift solenoid valves A and B according to signals from the ECM (throttle opening) and revolution sensor to select
the optimum gear position on the basis of the shift schedule memorized in the TCM.

Pilot pressure generated by the operation of shift solenoid valves A and B is applied to the end face of shift
valves A and B.
The drawing above shows the operation of shift valve B. When the shift solenoid valve is ON, pilot pressure
applied to the end face of the shift valve overcomes spring force, moving the valve upward.
LOCK-UP CONTROL
The torque converter clutch piston in the torque converter is locked to eliminate torque converter slip to
increase power transmission efficiency. The solenoid valve is controlled by an ON-OFF duty signal sent from
the TCM. The signal is converted to an oil pressure signal which controls the lock-up piston.
Conditions for Lock-up Operation
When vehicle is driven in 4th gear position, vehicle speed and throttle opening are detected. If the detected
values fall within the lock-up zone memorized in the TCM, lock-up is performed.

LOCK-UP RELEASED
The OFF-duration of the torque converter clutch solenoid valve is long, and pilot pressure is high. The pilot
pressure pushes the end face of the torque converter clutch control valve in combination with spring force to
move the valve to the left. As a result, converter pressure is applied to chamber A (torque converter clutch piston release side). Accordingly, the torque converter clutch piston remains unlocked.
LOCK-UP APPLIED
When the OFF-duration of the torque converter clutch solenoid valve is short, pilot pressure drains and
becomes low. Accordingly, the control valve moves to the right by the pilot pressure of the other circuit and
converter pressure. As a result, converter pressure is applied to chamber B, keeping the torque converter
clutch piston applied.
Also smooth lock-up is provided by transient application and release of the lock-up.

OVERRUN CLUTCH CONTROL (ENGINE BRAKE CONTROL)
Forward one-way clutch is used to reduce shifting shocks in downshifting operations. This clutch transmits
engine torque to the wheels. However, drive force from the wheels is not transmitted to the engine because
the one-way clutch rotates idle. This means the engine brake is not effective.
The overrun clutch operates when the engine brake is needed.

Overrun Clutch Solenoid Valve Control
The overrun clutch solenoid valve is operated by an ON-OFF signal
transmitted by the TCM to provide overrun clutch control (engine
brake control).
When this solenoid valve is ON, the pilot pressure drain port closes.
When it is OFF, the drain port opens.
During the solenoid valve ON pilot pressure is applied to the end
face of the overrun clutch control valve.
SAT015J
Overrun Clutch Control Valve Operation
When the solenoid valve is ON, pilot pressure is applied to the overrun clutch control valve. This pushes up the overrun clutch control
valve. The line pressure is then shut off so that the clutch does not
engage.
When the solenoid valve is OFF, pilot pressure is not generated. At
this point, the overrun clutch control valve moves downward by
spring force. As a result, overrun clutch operation pressure is provided by the overrun clutch reducing valve. This causes the overrun
clutch to engage.
In the 1 position, the overrun clutch control valve remains pushed
down so that the overrun clutch is engaged at all times.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION
Introduction
PFP:00000
ECS0095Z
The A/T system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM (transaxle control
module) in combination with the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp)
and is stored as a DTC in the ECM memory but not the TCM memory.
The second is the TCM original self-diagnosis indicated by the A/T check (position) indicator lamp. The malfunction is stored in the TCM memory. The detected items are overlapped with OBD-II self-diagnostic items.
For details, refer to AT-44, "OBD-II Function for A/T System" .
OBD-II Function for A/T System
ECS00960
The ECM provides emission-related on board diagnostic (OBD-II) functions for the A/T system. One function
is to receive a signal from the TCM used with OBD-related parts of the A/T system. The signal is sent to the
ECM when a malfunction occurs in the corresponding OBD-related part. The other function is to indicate a
diagnostic result by means of the MIL (malfunction indicator lamp) on the instrument panel. Sensors, switches
and solenoid valves are used as sensing elements.
The MIL automatically illuminates in One or Two Trip Detection Logic when a malfunction is sensed in relation
to A/T system parts.
One or Two Trip Detection Logic of OBD-II
ECS00961
ONE TRIP DETECTION LOGIC
If a malfunction is sensed during the first test drive, the MIL will illuminate and the malfunction will be stored in
the ECM memory as a DTC. The TCM is not provided with such a memory function.
TWO TRIP DETECTION LOGIC
When a malfunction is sensed during the first test drive, it is stored in the ECM memory as a 1st trip DTC
(diagnostic trouble code) or 1st trip freeze frame data. At this point, the MIL will not illuminate. — First Trip
If the same malfunction as that experienced during the first test drive is sensed during the second test drive,
the MIL will illuminate. — Second Trip
A/T-related parts for which the MIL illuminates during the first or second test drive are listed below.

The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.
OBD-II Diagnostic Trouble Code (DTC)
ECS00962
HOW TO READ DTC AND 1ST TRIP DTC
DTC and 1st trip DTC can be read by the following methods.
(
With CONSULT-II or
GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710,
P0720, P0725, etc.
These DTCs are prescribed by SAE J2012.
(CONSULT-II also displays the malfunctioning component or system.)
●
1st trip DTC No. is the same as DTC No.
●
Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction. However, in case of the Mode II and GST they do not indicate whether the malfunction is still occurring
or occurred in the past and returned to normal.
CONSULT-II can identify them as shown below. Therefore, using CONSULT-II (if available) is recommended.

Freeze Frame Data and 1st Trip Freeze Frame Data
The ECM has a memory function, which stores the driving condition such as fuel system status, calculated
load value, engine coolant temperature, short term fuel trim, long term fuel trim, engine speed and vehicle
speed at the moment the ECM detects a malfunction.
Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data,
and the data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II
or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
details, refer to ! Hyper-link Error ! .
Only one set of freeze frame data (either 1st trip freeze frame data of freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the following priorities to update the data.

"DIAGNOSTIC WORKSHEET" . Reference pages are provide following the items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each solenoid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Manual may differ slightly. This occurs because of the following reasons:
–
Actual shift schedule has more or less tolerance or allowance,
–
Shift schedule indicated in Service Manual refers to the point where shifts start, and
–
Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is displayed upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II

TROUBLE DIAGNOSIS - INTRODUCTION
[RE4F04B]
TROUBLE DIAGNOSIS - INTRODUCTION
Introduction
The TCM receives a signal from the vehicle speed sensor, ECM
(throttle opening) or park/neutral position (PNP) switch and provides
shift control or lock-up control via A/T solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the
A/T system for malfunction-diagnostic purposes. The TCM is capable of diagnosing malfunctioning parts while the ECM can store malfunctions in its memory.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good operating condition and be free of valve seizure, solenoid valve malfunction, etc.
PFP:00000
ECS00966
SAT631IA
It is much more difficult to diagnose a problem that occurs intermittently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replacement of good parts.
A visual check only, may not find the cause of the problems. A road
test with CONSULT-II (or GST) or a circuit tester connected should
be performed. Follow the “Work Flow”. Refer to AT-68, "Work Flow" .
SAT632I
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The customer can supply good information about such problems, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “DIAGNOSTIC WORKSHEET” like the
example on page AT-66 should be used.
Start your diagnosis by looking for “conventional” problems first. This
will help troubleshoot driveability problems on an electronically controlled engine vehicle.
Also check related Service bulletins for information.

A/T Fluid Cooler Cleaning
ECS00969
Whenever an automatic transaxle is repaired, overhauled, or replaced, the A/T fluid cooler mounted in the
radiator must be inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can contaminate the newly serviced A/T or, in severe cases, can block or restrict the flow of A/T fluid. In either case,
malfunction of the newly serviced A/T may result.
Debris, if present, may build up as A/T fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
A/T FLUID COOLER CLEANING PROCEDURE

This is an OBD-II self-diagnostic item and not available in TCM self-diagnosis.
This malfunction will not be detected while the A/T check (position) indicator lamp is indicating another B
self-diagnosis malfunction.
This malfunction is detected when the A/T does not shift into first gear position as instructed by the TCM.

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as
follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (1st) supposed by TCM, the slip ratio will be more than
normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when either shift solenoid valve A is stuck open or shift solenoid valve B is
stuck open.
Gear positions supposed by TCM are as follows.
In case of gear position with no malfunctions: 1 , 2, 3 and 4 positions
In case of gear position with shift solenoid valve A stuck open: 2* , 2, 3 and 3 positions
In case of gear position with shift solenoid valve B stuck open: 4* , 3, 3 and 4 positions to each gear position

ECS0097I
This is an OBD-II self-diagnostic item and not available in TCM self-diagnosis.
This malfunction will not be detected while the A/T check (position) indicator lamp is indicating another B
self-diagnosis malfunction.
This malfunction is detected when the A/T does not shift into third gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such AT
as control valve sticking, improper solenoid valve operation, malfunctioning servo piston or brake band,
etc.

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as
follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (3rd) supposed by TCM, the slip ratio will be more than
normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve A is stuck closed.
Gear positions supposed by TCM are as follows.
In case of gear position with no malfunctions: 1, 2, 3 and 4 positions
In case of gear position with shift solenoid valve A stuck closed: 1, 1, 4* and 4 positions to each gear position
above
*: P0733 is detected.
Diagnostic trouble code A/T 3RD GR FNCTN with CONSULT-II or P0733 without CONSULT-II is detected

The torque converter clutch solenoid valve is activated, with the gear
in D4 , by the TCM in response to signals sent from the vehicle
speed and the ECM (throttle opening). Lock-up piston operation will
then be controlled.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up
condition, the engine speed should not change abruptly. If there is a
big jump in engine speed, there is no lock-up.

ECS00981
This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as
follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is much lower than the position (4th) supposed by TCM, the slip ratio will be much
less than normal. In case the ratio does not reach the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve B is stuck closed.
Gear positions supposed by TCM are as follows.
In case of gear position with no malfunctions: 1, 2, 3 and 4 positions
In case of gear position with shift solenoid valve B stuck closed: 1, 2, 2 and 1* positions to each gear position
above
*: P0744 is detected.
Diagnostic trouble code A/T TCC S/V FNCTN with CONSULT-II or P0744 without CONSULT-II is detected
when A/T cannot perform lock-up even if electrical circuit is good.
Possible Cause
ECS00982
Check the following items.
●
Line pressure solenoid valve
●
Torque converter clutch solenoid valve
●

DTC U1000 CAN COMMUNICATION LINE
Description
PFP:23710
ECS00990
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

A/T SHIFT LOCK SYSTEM
Description
●
●
PFP:34950
ECS009AF
The electrical key interlock mechanism also operates as a shift lock:
With the key switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.
The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock solenoid and by the operation of the rotator and slider located inside the key cylinder.

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
ECS009C8
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front AT
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
F
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
G
Precautions for On Board Diagnostic (OBD) System of A/T and Engine
ECS009C9
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
●
Be sure to turn the ignition switch “OFF” and disconnect the negative battery cable before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MIL to light up.
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
●
Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
●
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.
●
Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.

●
●
●
●
●
●
●
●
●
Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transaxle.
Place disassembled parts in order for easier and proper assembly.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
Gaskets, seals and O-rings should be replaced any time the transaxle is disassembled.
It is very important to perform functional tests whenever they are indicated.
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
After overhaul, refill the transaxle with new ATF.
When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque
converter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to AT-398, "A/T FLUID" .

POWER TRANSMISSION
“N” position
Since both the forward clutch and the direct clutch are released, torque from the input shaft drive is not transmitted to the output shaft.
“P” position
●
●
The same as for the “N” position, both the forward clutch and the direct clutch are released, so torque
from the input shaft drive is not transmitted to the output shaft.
The parking pole linked with the selector lever meshes with the parking gear and fastens the output shaft
mechanically.

CAN Communication
ECS009CM
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
For details, refer to LAN-20, "CAN COMMUNICATION" .

ECS009CN
The pressure control solenoid valve A controls linear line pressure by control signal from TCM and line
pressure for clutches and brakes to reduce shift shock.
This pressure control solenoid valve A controls the pressure regulator valve as the signal pressure and
adjusts the pressure of the operating oil discharged from the oil pump to the line pressure most appropriate to the driving state.

A/T CONTROL SYSTEM
[RE5F22A]
SPECIAL SHIFT MODE
Upslope Mode
When TCM detects upslope from load of engine torque and decrease of acceleration, this mode changes shift
points in high-speed side according to the upslope degree and avoids busy shift of A/T.
Downslope Mode
When TCM detects downslope from increase of acceleration with accelerator full close, this mode operates
moderate engine brake by changing shift points in high-speed side.
Hot Mode Control
This control lowers ATF temperature by changing shift points when the temperature is extremely high.
MANUAL MODE
Driver oneself can select favorite gear and enjoy sports driving of manual transmission sense by shifting lever
from D position to manual mode position and + (up shift) / - (down shift). But lock-up control is operated automatically. Shift control is operated again by shifting from manual gear position to D position. Following control
is operated when manual mode.
Automated Up Shift Control
In order to avoid the over speed of the engine, up shift operate automatically, if it becomes over a constant
vehicle speed.
Automated Down Shift Control
In order to avoid the stall of the engine, down shift operate automatically, if it becomes under a constant vehicle speed.
Up Shift Permission Control
In order to avoid the stall of the engine, up shift is done only at over a constant vehicle speed.
Down Shift Permission Control
In order to avoid the over speed of the engine, down shift is done only at under a constant vehicle speed.
UP/DOWN SHIFT LEARNING CONTROL
This control learns the pressure to each clutch or brake in order to reduce shifting shock at each shifting (Up,
Down, Manual down, Coast down).
N-D SHIFT CONTROL
This control improves the N-D shift quality due to controlling line pressure solenoid valve according to forward
clutch piston stroke learned in N-D shift learning control and applying best hydraulic pressure to forward clutch
at N-D shift.
N-D SHIFT LEARNING CONTROL
This control learns the forward clutch hydraulic pressure due to monitoring a forward clutch engaging time and
a rotation change rate.
N-R SHIFT CONTROL
This control improves the N-R shift quality due to controlling shift pressure solenoid valve according to direct
clutch piston stroke learned in N-R shift learning control and applying best hydraulic pressure to direct clutch
at N-R shift.
N-R SHIFT LEARNING CONTROL
This control learns the direct clutch hydraulic pressure due to monitoring a direct clutch engaging time and a
rotation change rate.
TORQUE REDUCTION CONTROL
This control improves the shift quality due to sending torque reduction request signal from TCM to ECM and
cutting engine torque increase of shift at N-D shift, N-R shift and 1 ⇔ 2 ⇔ 3 ⇔ 4 ⇔ 5.
If accelerator pedal is depressed rapidly, this control establishes the upper limit value of engine torque and
avoids engine flare at 2 ⇔ 3, 3 ⇔ 4 and 4 Þ 2 of clutch to clutch shift.

SMOOTH LOCK-UP CONTROL
When shifting from the lock-up released state to the lock-up applied state, the current output to the pressure
control solenoid valve C is controlled with the TCM. In this way, when shifting to the lock-up applied state, the
torque converter clutch is temporarily set to the half-clutched state to reduce the shock.
Half-Clutched State
●
The current output from the TCM to the pressure control solenoid valve C is varied to steadily increase the
pressure control solenoid valve C pressure.
In this way, the lock-up apply pressure gradually rises and while the torque converter clutch piston is put
into half-clutched status, the torque converter clutch piston operating pressure is increased and the coupling is completed smoothly.
Slip Lock-up Control
●
In the slip region, the pressure control solenoid valve C current is controlled with the TCM to put it into the
half-clutched state. This absorbs the engine torque fluctuation and lock-up operates from low speed.
This raises the fuel efficiency for 4th and 5th gears at both low speed and when the accelerator has a low
degree of opening.

[RE5F22A]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
Introduction
PFP:00028
A
ECS009CQ
The A/T system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (OBD-II) performed by the TCM in combination B
with the ECM. The malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC in
the ECM memory but not the TCM memory.
The second is the TCM original self-diagnosis indicated by the A/T CHECK indicator lamp. The malfunction is
stored in the TCM memory. The detected items are overlapped with OBD-II self-diagnostic items. For detail, AT
refer to AT-463, "SELF-DIAG RESULT MODE" .
OBD-II Function for A/T System
ECS009CR
The ECM provides emission-related on board diagnostic (OBD-II) functions for the A/T system. One function
is to receive a signal from the TCM used with OBD-related parts of the A/T system. The signal is sent to the
ECM when a malfunction occurs in the corresponding OBD-related part. The other function is to indicate a
diagnostic result by means of the MIL (malfunction indicator lamp) on the instrument panel. Sensors, switches
and solenoid valves are used as sensing elements.
The MIL automatically illuminates in One or Two Trip Detection Logic when a malfunction is sensed in relation
to A/T system parts.
One or Two Trip Detection Logic of OBD-II
D
E
F
ECS009CS
ONE TRIP DETECTION LOGIC
If a malfunction is sensed during the first test drive, the MIL will illuminate and the malfunction will be stored in
the ECM memory as a DTC. The TCM is not provided with such a memory function.
G
TWO TRIP DETECTION LOGIC
H
When a malfunction is sensed during the first test drive, it is stored in the ECM memory as a 1st trip DTC
(diagnostic trouble code) or 1st trip freeze frame data. At this point, the MIL will not illuminate. — 1st Trip
If the same malfunction as that experienced during the first test drive is sensed during the second test drive,
the MIL will illuminate. — 2nd Trip
The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.

OBD-II Diagnostic Trouble Code (DTC)
J
ECS009CT
HOW TO READ DTC AND 1ST TRIP DTC
DTC and 1st trip DTC can be read by the following methods.
( with CONSULT-II or
GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710 etc.
These DTC are prescribed by SAE J2012.
(CONSULT-II also displays the malfunctioning component or system.)
●
1st trip DTC No. is the same as DTC No.
●
Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction. However, in case of the Mode II and GST, they do not indicate whether the malfunction is still occurring
or occurred in the past and returned to normal.
CONSULT-II can identify them as shown below, therefore, CONSULT-II (if available) is recommended.
A sample of CONSULT-II display for DTC and 1st trip DTC is shown
on the next page. DTC or 1st trip DTC of a malfunction is displayed
in SELF-DIAGNOSTIC RESULTS mode for “ENGINE” with CONSULT-II. Time data indicates how many times the vehicle was driven
after the last detection of a DTC.

If the DTC is being detected currently, the time data will be “0”.
SAT015K
If a 1st trip DTC is stored in the ECM, the time data will be “1t”.
SAT016K
Freeze Frame Data and 1st Trip Freeze Frame Data
The ECM has a memory function, which stores the driving condition such as fuel system status, calculated
load value, engine coolant temperature, short term fuel trim, long term fuel trim, engine speed and vehicle
speed at the moment the ECM detects a malfunction.
Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data,
and the data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II
or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
detail, refer to EC-659, "FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA" .
Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the following priorities to update the data.

Except the above items (Includes A/T related items)
1st trip freeze frame data
Both 1st trip freeze frame data and freeze frame data (along with the DTC) are cleared when the ECM memory is erased.
HOW TO ERASE DTC
The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as
described following.
●
If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours.
●
When you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode
selector on the ECM.
The following emission-related diagnostic information is cleared from the ECM memory when erasing DTC
related to OBD-II. For details, refer to EC-654, "EMISSION-RELATED DIAGNOSTIC INFORMATION ITEMS"

Fail-Safe
ECS009CW
The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is a malfunction in a main electronic control input/output signal circuit.
In fail-safe mode, a driving condition is selected according to the malfunctioning location, and line pressure is
set at the maximum. For this reason, the customer will be subjected to uncomfortable “slipping” or “poor acceleration” of the vehicle.
In that case, handle according to the “diagnostics flow” (Refer to AT-435 ).

How To Perform Trouble Diagnosis For Quick and Accurate Repair
ECS009CX
INTRODUCTION
The TCM receives a signal from the vehicle speed signal, throttle position sensor (accelerator pedal position
sensor) or PNP switch and provides shift control or lock-up control via A/T solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the
A/T system for malfunction-diagnostic purposes. The TCM is capable of diagnosing malfunctioning parts while the ECM can store malfunctions in its memory.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good operating condition and be free of valve seizure, solenoid valve malfunction, etc.
SAT631IB
It is much more difficult to diagnose an error that occurs intermittently rather than continuously. Most intermittent errors are caused
by poor electric connections or improper wiring. In this case, careful
checking of suspected circuits may help prevent the replacement of
good parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-II (or GST) or a circuit tester connected should be
performed. Follow the AT-435, "WORK FLOW" .
SAT632I
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The customer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic Worksheet” as shown on
the example (Refer to AT-436 ) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.

WORK FLOW
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symptoms or conditions for a customer complaint.
Make good use of the two sheets provided, “Information From Customer” (Refer to AT-436 ) and “Diagnostic
Worksheet” (Refer to AT-436 ), to perform the best troubleshooting possible.

CONSULT-II Function (TCM)

CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.

WORK SUPPORT
SELF-DIAG RESULTS
DATA MONITOR
CAN DIAG SUPPORT MNTR
ACTIVE TEST
FUNCTION TEST
ECU PART NUMBER
Description
Supports inspections and adjustments. Commands are transmitted to the TCM for setting the status
suitable for required operation, input/output signals are received from the TCM and received data is
displayed.
Displays TCM self-diagnosis results.
Displays TCM input/output data in real time.
The result of transmit/receive diagnosis of CAN communication can be read.
Operation of electrical loads can be checked by sending drive signal to them.
Conducted by CONSULT-II instead of a technician to determine whether each system is "OK" or "NG".
TCM part number can be read.
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” (Refer to AT-463 ), place check
marks for results on the AT-436, "DIAGNOSTIC WORKSHEET" . Reference pages are provided following the
items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each solenoid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Manual may differ slightly. This occurs because of the following reasons:
–
Actual shift schedule has more or less tolerance or allowance,
–
Shift schedule indicated in Service Manual refers to the point where shifts start, and
–
Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Display of solenoid valves on CONSULT-II changes at the start of shifting, while gear position is displayed
upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
CONSULT-II SETTING PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.

ECS009EC
The turbine revolution sensor detects forward clutch drum rpm
(revolutions per minute). It is located on the input side of the
automatic transaxle. The revolution sensor is located on the output side of the automatic transaxle. With the two sensors, input
and output rpms are accurately detected. The result is optimal
shift timing during deceleration and improved shifting.
Hall IC is installed in turbine revolution sensor, it itself handles in
pulse of rectangular wave signal and transmits it to TCM due to
hall effect. TCM recognizes the pulse with input rpm speed. Size
of output doesn't depend on a rotation number and is fixed.

DTC P0795 PRESSURE CONTROL SOLENOID VALVE C (TCC AND SHIFT PRESSURE)
PFP:31940
Description
ECS009HL
●
●
●
●
The pressure control solenoid valve C is normally low, 3-port linear pressure control solenoid.
The pressure control solenoid valve C is activated to control the
apply and release of the 2nd brake and 1st and reverse brake,
and torque converter clutch.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 1/8) in lockup condition, the engine speed should not change abruptly. If
there is a big jump in engine speed, there is no lock-up.

●
A
ECS009HS
This malfunction will not be detected while the A/T CHECK indicator lamp is indicating another self-diagnosis malfunction.
B
This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such
as control valve sticking, improper solenoid valve operation, etc.
The pressure control solenoid valve C is normally low, 3-port linAT
ear pressure control solenoid.
The pressure control solenoid valve C is activated to control the
apply and release of the 2nd brake and 1st and reverse brake,
D
and torque converter clutch.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
E

●
Park/neutral position (PNP) switch
The park/neutral (PNP) switch assembly includes a transmission range switch. The transmission range
switch detects the selector lever position and sends a signal to the TCM.
Stop lamp switch signal
Detects the brake pedal state (stop lamp switch is ON or OFF) and sends a signal via CAN communication line to the TCM.
Closed throttle position signal
ECM judges throttle opening based on a signal from accelerator pedal position sensor, and sends the signal via CAN communication line to TCM.

ECS009J4
The electrical key interlock mechanism also operates as a shift lock:
With the key switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other posi- B
tion unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.
AT
The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock solenoid and by the operation of the rotator and slider located inside the key cylinder.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS002PJ
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Working with HFC-134a (R-134a)
EJS002PK
WARNING:
●
CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed compressor failure is likely to occur. Refer ATC-4, "Contaminated Refrigerant" . To
determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant
Recovery/Recycling Recharging equipment and Refrigerant Identifier.
●
Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
If oil other than that specified is used, compressor failure is likely to occur.
●
The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:
–
When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
–
When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system.
–
Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without
proper sealing, oil will become moisture saturated and should not be used.
–
Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting
requirements of SAE J2210 [HFC-134a (R-134a) recycling equipment], or J2209 [HFC-134a (R-134a)
recycling equipment], If accidental system discharge occurs, ventilate work area before resuming
service. Additional health and safety information may be obtained from refrigerant and oil manufacturers.
–
Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.
Contaminated Refrigerant
EJS002PL
If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are:
●
Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant
into the atmosphere.
●
Explain that recovery of the contaminated refrigerant could damage your service equipment and refrigerant supply.
●
Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
●
If you choose to perform the repair, recover the refrigerant using only dedicated equipment and containers. Do not recover contaminated refrigerant into your existing service equipment. If your facility
Revision: November 2006
ATC-4
2006 Altima
PRECAUTIONS
●
does not have dedicated recovery equipment, you may contact a local refrigerant product retailer for available service. This refrigerant must be disposed of in accordance with all federal and local regulations. In
addition, replacement of all refrigerant system components on the vehicle is recommended.
If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN
Customer Affairs for further assistance.

B
EJS002PM
WARNING:
●
Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
●
Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
●
Do not store or heat refrigerant containers above 52°C (125°F).
●
Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
●
Do not intentionally drop, puncture, or incinerate refrigerant containers.
●
Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
●
Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
●
Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air conditioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refrigerant manufacturers.

EJS002PN
The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
I
(UV) lamp is required to illuminate the dye when inspecting for leaks.
Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
ATC
A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).
Always remove any dye from the leak area after repairs are complete to avoid a misdiagnosis during a K
future service.
Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period
L
of time cannot be removed .
Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
Do not use more than one refrigerant dye bottle (1/4 ounce / 7.4 cc) per A/C system.
M
Leak detection dyes for HFC-134a (R-134a) and HC-12 (R-12) A/C systems are different. Do not use
HFC-134a (R-134a) leak detection dye in R-12 A/C systems or HC-12 (R-12) leak detection dye in HFC134a (R-134a) A/C systems or A/C system damage may result.
The fluorescent properties of the dye will remain for over three (3) years unless a compressor failure
occurs.

FEATURES OF NEW TYPE REFRIGERANT CONNECTION
●
●
The O-ring has been relocated. It has also been provided with a groove for proper installation. This eliminates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of
the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing
characteristics.
The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facilitating piping connections.

Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is F
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
G
●
When the compressor is removed, store it in the same position as it is when mounted on the car.
Failure to do so will cause oil to enter the low pressure chamber.
●
When connecting tubes, always use a torque wrench and a back-up wrench.
H
●
After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
●
When installing an air conditioner in the vehicle, connect the pipes as the final stage of the operation. Do not remove the seal caps of pipes and other components until just before required for
I
connection.
●
Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
ATC
●
Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
●
Always replace used O-rings.
●
When connecting tube, apply oil to circle of the O-rings shown in illustration. Be careful not to K
apply oil to threaded portion.

●
●
EJS002PQ
Plug all openings to prevent moisture and foreign matter from entering.
When the compressor is removed, store it in the same position as it is when mounted on the car.
When replacing or repairing compressor, follow “Maintenance of Oil Quantity in Compressor”
exactly. Refer to ATC-19, "Maintenance of Oil Quantity in Compressor" .
Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with oil,
wipe it off by using a clean waste cloth moistened with thinner.
After compressor service operation, turn the compressor shaft by hand more than 5 turns in both
directions. This will equally distribute oil inside the compressor. After the compressor is installed,
let the engine idle and operate the compressor for 1 hour.
After replacing the compressor magnet clutch, apply voltage to the new one and check for normal
operation. [Gap between clutch disc and pulley is 0.3 - 0.6 mm (0.012 - 0.024 in)]
Precautions for Service Equipment

PRECAUTIONS
VACUUM PUMP
A
The oil contained inside the vacuum pump is not compatible with the
specified oil for HFC-134a (R-134a) A/C systems. The vent side of
the vacuum pump is exposed to atmospheric pressure so the vacuum pump oil may migrate out of the pump into the service hose.
This is possible when the pump is switched off after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve situated near the
hose-to-pump connection, as follows.
●
Usually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.
●
For pumps without an isolator, use a hose equipped with a manual shut-off valve near the pump end. Close the valve to isolate
the hose from the pump.
●
If the hose has an automatic shut off valve, disconnect the hose
from the pump: as long as the hose is connected, the valve is
open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under a no vacuum condition. Such valves may restrict the pump's
ability to pull a deep vacuum and are not recommended.

REFRIGERATION SYSTEM
REFRIGERATION SYSTEM
Refrigerant Cycle
PFP:KA990
A
EJS002PW
REFRIGERANT FLOW
The refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank,
through the evaporator, and back to the compressor. The refrigerant evaporation through the evaporator coil is
controlled by an externally equalized expansion valve, located inside the evaporator case.
Refrigerant System Protection
EJS002PX
REFRIGERANT PRESSURE SENSOR
The refrigerant system is protected against excessively high or low pressures by the refrigerant pressure sensor, located on the condenser. If the system pressure rises above or falls below the specifications, the refrigerant pressure sensor detects the pressure inside the refrigerant line and sends the voltage signal to the ECM.
The ECM then ceases to supply power to the A/C relay which disengages and stops the compressor when
pressure on the high pressure side (as detected by refrigerant pressure sensor) is over approximately 2,746
kPa (28 kg/cm2 , 398 psi), or below approximately 120 kPa (1.22 kg/cm2 , 17.4 psi).
B
C
D
E
PRESSURE RELIEF VALVE
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
When the pressure of refrigerant in the system increases to an abnormal level [more than 3,727 kPa (38 kg/
cm2 , 540 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into
the atmosphere.

AIR CONDITIONER CONTROL
AIR CONDITIONER CONTROL
Overview Air Conditioner LAN Control System
PFP:27500
EJS002Q0
The LAN (local area network) system consists of front air control, air mix door motor, intake door motor, and
mode door motor.
A configuration of these components is shown in the diagram below.
WJIA0876E
System Construction
EJS002Q1
A small network is constructed between the front air control, air mix door motor, intake door motor, and mode
door motor. The front air control and motors are connected by data transmission lines and motor power supply
lines. The LAN network is built through the ground circuits of the two motors.
Addresses, motor opening angle signals, motor stop signals and error checking messages are all transmitted
through the data transmission lines connecting the front air control and each motor.
The following functions are contained in LCUs built into the air mix door motor, intake door motor, and the
mode door motor.
●
Address
●
Motor opening angle signals
●
Data transmission
●
Motor stop and drive decision
●
Opening angle sensor (PBR function)
●
Comparison
●
Decision (front air control indicated value and motor opening angle comparison)
WJIA0877E
OPERATION
The front air control receives data from each of the sensors. It then sends air mix door, mode door and intake
door opening angle data to the air mix door motor LCU, mode door motor LCU and intake door motor LCU.
The air mix door motor, mode door motor and intake door motor read their respective signals according to the
address signal. Opening angle indication signals received from the front air control and each of the motor position sensors are compared by the LCUs in each motor with the existing decision and opening angles. Subse-

D
WJIA0878E
TRANSMISSION DATA AND TRANSMISSION ORDER
E
Front air control data is transmitted consecutively to each of the door motors following the form shown in figure
below.
Start: Initial compulsory signal sent to each of the door motors.
Address: Data sent from the front air control is selected according to data-based decisions made by the air mix F
door motor, mode door motor and intake door motor.
If the addresses are identical, the opening angle data and error check signals are received by the door motor
LCUs. The LCUs then make the appropriate error decision. If the opening angle data is normal, door control G
begins.
If an error exists, the received data is rejected and corrected data received. Finally, door control is based upon
the corrected opening angle data.
H
Opening angle: Data that shows the indicated door opening angle of each door motor.
Error check: Procedure by which sent and received data is checked for errors. Error data is then compiled.
The error check prevents corrupted data from being used by the air mix door motor, mode door motor and
intake door motor. Error data can be related to the following problems.
I
●
Abnormal electrical frequency
●
Poor electrical connections
ATC
●
Signal leakage from transmission lines
●
Signal level fluctuation
Stop signal: At the end of each transmission, a stop operation, in-operation, or internal problem message is
K
delivered to the front air control. This completes one data transmission and control cycle.

AIR CONDITIONER CONTROL
FAN SPEED CONTROL
Fan speed is automatically controlled based on temperature setting, ambient temperature, in-vehicle temperature, intake temperature, amount of sunload and air mix door position.
With fan switch set to AUTO, the blower motor starts to gradually increase air flow volume.
When engine coolant temperature is low, the blower motor operation is delayed to prevent cool air from flowing.
INTAKE DOOR CONTROL
The intake door is automatically controlled by the: temperature setting, ambient temperature, in-vehicle temperature, intake temperature, amount of sunload and ON-OFF operation of the compressor.
MODE DOOR CONTROL
The mode door is automatically controlled by the: temperature setting, ambient temperature, in-vehicle temperature, intake temperature and amount of sunload.

Automatic Mode
I
In the automatic mode, the blower motor speed is calculated by the front air control based on inputs from the
PBR, in-vehicle sensor, sunload sensor, intake sensor and ambient sensor.
When the air flow is increased, the duty ratio of the blower fan motor's drive signal is changed at 8% sec. to
ATC
prevent a sudden increase in air flow.
In addition to manual air flow control and the normal automatic air flow control, starting air flow control, low
water temperature starting control and high passenger compartment temperature starting control are availK
able.
Starting Fan Speed Control
Start Up From COLD SOAK Condition (Automatic mode)
In a cold start up condition where the engine coolant temperature is below 56°C (133°F), the blower will not
operate for a short period of time (up to 150 seconds). The exact start delay time varies depending on the
ambient and engine coolant temperature.
In the most extreme case (very low ambient) the blower starting delay will be 150 seconds as described
above. After this delay, the blower will operate at low speed until the engine coolant temperature rises above
56°C (133°F), at which time the blower speed will increase to the objective speed.
Start Up From Normal or HOT SOAK Condition (Automatic mode)
The blower will begin operation momentarily after the A/C button is pushed. The blower speed will gradually
rise to the objective speed over a time period of 3 seconds or less (actual time depends on the objective
blower speed).
Fan Speed Compensation
Sunload
When the in-vehicle temperature and the set temperature are very close, the fan will be operating at low
speed. The low speed will vary depending on the sunload. During conditions of high sunload, the fan low
speed is "normal" low speed (approx. 6V). During low or no sunload conditions, the low speed will drop to
"low" low speed (approx. 5V).

Ambient Sensor
C
The ambient sensor is attached to the front bumper reinforcement. It
detects ambient temperature and converts it into a resistance value
which is then input into the front air control.
D
E
F
WJIA0097E
AMBIENT TEMPERATURE INPUT PROCESS
G
The automatic amplifier includes a processing circuit for the ambient sensor input. However, when the temperature detected by the ambient sensor increases quickly, the processing circuit retards the front air control function. It only allows the front air control to recognize an ambient temperature increase of 0.33°C (0.6°F) per 100
seconds.
As an example, consider stopping for a cup of coffee after high speed driving. Although the actual ambient
temperature has not changed, the temperature detected by the ambient sensor will increase. This is because
the heat from the engine compartment can radiate to the front grille area, location of the ambient sensor.

TROUBLE DIAGNOSIS
Sunload Sensor Circuit
EJS002QP
COMPONENT DESCRIPTION
The sunload sensor is located on the right defroster grille. It detects
sunload entering through windshield by means of a photo diode. The
sensor converts the sunload into a current value which is then input
into the front air control.
WJIA0086E
SUNLOAD INPUT PROCESS
The front air control also includes a processing circuit which averages the variations in detected sunload over
a period of time. This prevents drastic swings in the ATC system operation due to small or quick variations in
detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor will vary whenever the trees obstruct the sunlight. The processing circuit averages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the ATC system operation. On the other hand, shortly
after entering a long tunnel, the system will recognize the change in sunload, and the system will react accordingly.

Checking for Refrigerant Leaks
A
EJS002RJ
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leakage, damage and corrosion. A/C oil leakage may indicate an area of refrigerant leakage. Allow extra inspection time in these areas when using either an electronic refrigerant leak detector or fluorescent dye leak
detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 25 - 50 mm (1 - 2 in) per second and no further than 6 mm (1/4 in) from the component.
CAUTION:
Moving the electronic leak detector probe slower and closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak Detector
EJS002RK
B
C
D
E
F
1.
Check A/C system for leaks using the UV lamp and safety goggles (J-42220) in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indi- G
cates an evaporator core assembly (tubes, core or TXV) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
H
3. After the leak is repaired, remove any residual dye using refrigerant dye cleaner (J-43872) to prevent
future misdiagnosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
I
leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and oils, may falsely trigger the leak detector. Make sure the surfaces to be checked are ATC
clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings K
and may damage the detector.
Dye Injection
EJS002RL
NOTE:
This procedure is only necessary when recharging the A/C system or when the compressor has seized and
has been replaced.
1.
2.
3.
4.
5.
6.
7.
Check the A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.52 kg/cm2 , 50 psi).
Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (J-41459).
CAUTION:
If repairing the A/C system or replacing a component, pour the dye directly into the open system
connection and proceed with the service procedures.
Connect the injector tool to the A/C LOW PRESSURE side service valve.
Start the engine and switch the A/C ON and fan ON.
While the A/C is operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye
through the low-pressure service valve using dye injector tool (J-41459), refer to the manufacturer's operating instructions.
With the engine still running, disconnect the injector tool from the low-pressure service valve.
Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leak size, operating conditions and location of the leak, it may take from a few minutes to a few days for
the dye to penetrate the leak and become visible.

Electronic Refrigerant Leak Detector
EJS002RM
PRECAUTIONS FOR HANDLING THE LEAK DETECTOR
When performing a refrigerant leak check, use a electronic refrigerant leak detector (J-41995) or equivalent. Ensure that the instrument
is calibrated and set properly per the manufacturer's operating
instructions.
The leak detector is a delicate device. In order to use the leak detector properly, read the manufacturer's operating instructions and perform any specified maintenance.
AHA281A
1.
Position the leak detector probe approximately 5 mm (3/16 in)
away from the point to be checked.
SHA707EA
2.
When testing, circle each fitting completely with the leak detector probe.
SHA706E
3.
Move the leak detector probe along the component at approximately 25 to 50 mm (1 to 2 in)/sec.
SHA708EA
CHECKING PROCEDURE
NOTE:
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in a calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Turn engine OFF.
2. Connect a suitable A/C manifold gauge set to the A/C service ports.
Revision: November 2006
ATC-116
2006 Altima
REFRIGERANT LINES
Check if the A/C refrigerant pressure is at least 345 kPa (3.52 kg/cm2 , 50 psi) above 16°C (61°F). If less
A
than specification, recover/evacuate and recharge the system with the specified amount of refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected since the system may not reach 345 kPa
B
(3.52 kg/cm2 , 50 psi) pressure.
4. Conduct the leak test from the high side (compressor discharge to evaporator inlet) to the low side (evaporator drain hose to the compressor shaft seal). Refer to ATC-104, "Components" . Clean the component
C
to be checked and move the leak detector probe completely around the connection/component.
Perform a leak check for the following areas:
● Compressor
D
● High and low-pressure hose fittings, relief valve and shaft seal.
● Liquid tank
● Refrigerant pressure sensor
E
● Service valves
– Check that all the service valve caps are secure on the service valves (to prevent leaks).
– After removing A/C manifold gauge set from service valves, wipe any residue from the valves to preF
vent any false readings by the leak detector.
● Evaporator
– With engine OFF, turn blower fan on high speed for at least 15 seconds to dissipate any refrigerant
G
trace around the evaporator. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer's recommended procedure for actual wait time) before inserting the leak detector probe into the
drain hose.
H
– Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with
water or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
I
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7 - 10.
ATC
7. Start engine.
8. Set the front air control as follows;
a. A/C switch: ON
K
b. Mode: Vent
c. Intake position: Recirculation
d. Temperature: MAX cold
L
e. Blower fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps 4
M
through 6 above.
Refrigerant leaks should be checked immediately after stopping
the engine. Begin with the leak detector at the compressor. The
pressure on the high pressure side will gradually drop after
refrigerant circulation stops and pressure on the low pressure
side will gradually rise, as shown in the graph. Some leaks are
more easily detected when pressure is high.
3.
SHA839E
11. Before connecting the recovery/recycling equipment to the A/C system, check the recovery/recycling
equipment gauges. No refrigerant pressure should be displayed. If pressure is displayed, recover the
refrigerant from the equipment lines and then check the refrigerant purity.
12. Confirm the refrigerant purity in the supply tank using the recovery/recycling equipment and the refrigerant
identifier equipment.
Revision: November 2006
ATC-117
2006 Altima
REFRIGERANT LINES
13. Confirm the refrigerant purity in the A/C system using the recovery/recycling equipment and the refrigerant identifier equipment.
14. Discharge the A/C system using approved refrigerant recovery/recycling equipment. Repair the leaking fitting or component as necessary.
15. Evacuate and recharge the A/C system and perform the leak test to confirm there are no refrigerant leaks.
16. Conduct the A/C performance test to ensure that the system works properly. Refer to ATC-69, "PERFORMANCE CHART" .

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS008RD
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

AV Switch Self-Diagnosis Function
EKS008RO
It can check ON/OFF operation of each switch in the audio unit (without NAVI) or AV switch (with NAVI) and
diagnose the input signals from the steering switch (with NAVI) (except TRIP on the steering wheel audio control switch).
STARTING THE SELF-DIAGNOSIS MODE (WITHOUT NAVI)
1.
2.
Turn ignition switch from OFF to ACC.
Press and hold the “CLOCK” switch and turn the volume control dial clockwise or counterclockwise for 30
clicks or more.
WKIA1935E

5.
6.
Then the self-diagnosis initiates.
Initially, all display segments will be illuminated.
Then the current software version will be displayed when the "TUNE UP" switch is pressed.
Then a speaker check will occur when the "TUNE DOWN" switch is pressed. The audio unit will send a
series of three beeps to each speaker channel in the following sequence: FR→FL→RL→RR. This check
will continue until any switch (except "TUNE UP", "TUNE DOWN" or volume) is operated.
Press each audio unit switch (except "TUNE UP", "TUNE DOWN" or volume). When each switch is
pressed, a series of three beeps will sound.
NOTE:
Steering wheel audio control switches (except base), "TUNE UP", "TUNE DOWN" and volume switches
are not included in this test.
STARTING THE SELF-DIAGNOSIS MODE (WITH NAVI)
1.
2.
3.
Turn ignition switch from OFF to ACC.
Within 10 seconds press and hold the switches “PAUSE/MUTE”
and “PREV” simultaneously for 3 seconds.
Then the self-diagnosis initiates. A single beep indicates selfdiagnosis mode is active.
Press each switch and listen for beep.
NOTE:
TRIP button on steering wheel audio control switch and CD
player LOAD and EJECT buttons are not included in this test
and will not beep when pressed.
WKIA2679E
EXITING THE SELF-DIAGNOSIS MODE
●

NOTE:
The following noise results from variations in field strength, such as fading noise and multi-path noise, or
external noise from trains and other sources. It is not a malfunction.
●
Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking the signal.
●
Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the
antenna at a different time from the waves which reflect off mountains or buildings.

NAVIGATION SYSTEM
System Description
PFP:25915
A
EKS00GAK
NOTE:
Refer to NAVI System Owner's Manual for system operation.
B
The navigation system periodically calculates the vehicle's current
position according to the following three signals: Travel distance of
the vehicle as determined by the vehicle speed sensor, turning angle
of the vehicle as determined by the gyroscope (angular velocity sensor), and the direction of vehicle travel as determined by the GPS
antenna (GPS information).
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVDROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen with a current-location mark.
C
D
E
WKIA1371E
F
By comparing the vehicle position detection results found by the
GPS and by map-matching, more accurate vehicle position data can
be used.
The current vehicle position will be calculated by detecting the distance the vehicle moved from the previous calculation point and its
direction.
G
H
I
SEL684V
TRAVEL DISTANCE
Travel distance calculations are based on the vehicle speed sensor input signal. Therefore, the calculation
may become incorrect as the tires wear down. To prevent this, an automatic distance fine adjustment function
has been adopted. Adjustments can be made in extreme cases such as driving with tire chain fitted on tires.
TRAVEL DIRECTION
Change in the travel direction of the vehicle is calculated by a gyroscope (angular velocity sensor) and a GPS
antenna (GPS information). As the gyroscope and GPS antenna have both merit and demerit, input signals
from them are prioritized in each situation. However, this order of priority may change in accordance with more
detailed travel conditions so that the travel direction is detected more accurately.
Type
Gyroscope (angular velocity sensor)

Disadvantage
●
Direction errors may accumulate when the
vehicle is driven for long distances without
stopping.
●
Correct direction cannot be detected when
the vehicle speed is low.
2006 Altima
NAVIGATION SYSTEM
MAP-MATCHING
Map-matching is a function that repositions the vehicle on the road
map when a new location is judged to be the most accurate. This is
done by comparing the current vehicle position, calculated by the
method described in the position detection principle, with the road
map data around the vehicle, read from the map DVD-ROM stored in
the DVD-ROM drive.
Therefore, the vehicle position may not be corrected after the vehicle
is driven over a certain distance or time in which GPS information is
hard to receive. In this case, the current-location mark on the display
must be corrected manually.
CAUTION:
The road map data is based on data stored in the map DVDROM.
●
In map-matching, alternative routes to reach the destination will
be shown and prioritized, after the road on which the vehicle is
currently driven has been judged and the current-location mark
has been repositioned.
If there is an error in distance and/or direction, the alternative
routes will be shown in different order of priority, and the wrong
road can be avoided.
If two roads are running in parallel, they are of the same priority.
Therefore, the current-location mark may appear on either of
them alternately, depending on maneuvering of the steering
wheel and configuration of the road.
●
●
Map-matching does not function correctly when the road on
which the vehicle is driving is new and not recorded in the map
DVD-ROM, or when the road pattern stored in the map data and
the actual road pattern are different due to repair.
When driving on a road not present in the map, the map-matching function may find another road and position the current-location mark on it. Then, when the correct road is detected, the
current-location mark may leap to it.
Effective range for comparing the vehicle position and travel
direction calculated by the distance and direction with the road
data read from the map DVD-ROM is limited. Therefore, when
there is an excessive gap between the current vehicle position
and the position on the map, correction by map-matching is not possible.

GPS (GLOBAL POSITIONING SYSTEM)
GPS (Global Positioning System) has been developed and controlled by the US Department of Defense. The system utilizes GPS
satellite (NAVSTAR), sending out radio waves while flying on an orbit
around the earth at the height of approx. 21,000 km (13,000 miles).
The GPS receiver calculates the vehicle's position in three dimensions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimensional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), utilizing the altitude data calculated previously by using radio waves from four or more GPS satelSEL526V
lites (two-dimensional positioning).
Accuracy of the GPS will deteriorate under the following conditions.
●
In two-dimensional positioning, the GPS accuracy will deteriorate when the altitude of the vehicle position
changes.
●
There may be an error of approximately 10 m (30 ft) in position detected by three-dimensional positioning,
which is more accurate than two-dimensional positioning. The accuracy can be even lower depending on
the arrangement of the GPS satellites utilized for the positioning.

●
●
Position detection is not possible when the vehicle is in an area where radio waves from the GPS satellite
do not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves
from the GPS satellites may not be received when some object is located over the GPS antenna.
Position correction by GPS is not available while the vehicle is stopped.

The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.
Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by combining this data with the data contained in the DVD-ROM map.
Location information is shown on liquid crystal display (display
unit).
Maps, traffic control regulations, and other pertinent information
can be easily read from the DVD-ROM disc.
The oscillator gyro sensor is used to detect changes in vehicle
steering angle.

On Board Self-Diagnosis Function
EKS008SO
DESCRIPTION
Diagnosis function consists of the self-diagnosis mode performed automatically and the CONFIRMATION/
ADJUSTMENT mode operated manually.
Self-diagnosis mode checks for connections between the units constituting this system, analyzes each
individual unit at the same time, and displays the results on the LCD screen.
CONFIRMATION/ADJUSTMENT mode is used to perform trouble diagnosis that require operation and
judgment by an operator (trouble that cannot be automatically judged by the system), to check/change the
set value, and to display the History of Errors of the navigation system.

HISTORY OF ERRORS
AV

SKIA0366E
DIAGNOSIS BY HISTORY OF ERRORS
The “Self-diagnosis” results indicate whether an error occurred during the period from when the ignition switch
is turned to ON until “Self-diagnosis” is completed.
Revision: November 2006
AV-105
2006 Altima
NAVIGATION SYSTEM
If an error occurred before the ignition switch was turned to ON and does not occur again until the “Self-diagnosis” is completed, the diagnosis result will be judged normal. Therefore, those errors in the past which cannot be found by the “Self-diagnosis” must be found by diagnosing the “History of Errors”.
The History of Errors displays the time and place of the most recent occurrence of that error. However, take
note of the following points.
●
Correct time of the error occurrence may not be displayed when the GPS antenna substrate within the
NAVI control unit has malfunctioned.
●
Place of the error occurrence is represented by the position of the current-location mark at the time when
the error occurred. If the current-location mark has deviated from the correct position, then the place of
the error occurrence may be located correctly.
●
The maximum number of occurrences which can be stored is 50. For the 51st and later occurrences, the
displayed number remains 50.
When a reproducible malfunction occurred but its cause cannot be identified because several errors are
present, record the item, number and place (longitude/latitude) of error occurrence (or delete the History of
Errors), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the History of Errors
to find the items which show an increased number of occurrences, and diagnose the item.

Symptom
Detouring route is recommended.
Landmarks on the map do not

Recommended route is far from
the starting point, passing points,
and destination.
Cause
Remedy
A
In some areas, highways (gray routes) are not
used for the search. (Note). Therefore, detour
route may be recommended.
Set the route closer to the basic route (gray
route).
A detour route may be shown when some traffic
regulation (one-way traffic, etc.) is set at the area
around the starting point or the destination.
Slightly move the starting point or the destination, or set the passing point on the route
of your choice.
B
In the area where highways (gray routes) are
used for the search, left turn has priority around
the current location and the destination (passing
points). For this reason, the recommended route
may be detouring.
System is not malfunctioning.
C
This can be happen due to omission or error in
the map data.
As a rule, an updated map DVD-ROM will be
released once a year. Wait until the latest
map has become available.
Starting point, passing points, and destination of
the route guide were set far from the desired
points because route searching data around
these area were not stored.
D
Reset the destination onto the road nearby. If
this road is one of the highways (gray
routes), an ordinary road nearby may be displayed as the recommended route.
NOTE:
Except for the ordinance-designated cities. (Malfunctioning areas may be changed in the updated map disc.)

ELK0192D
Spiral roads
When driving on a large, continuous spiral
road (such as loop bridge), turning angle
error is accumulated and the vehicle mark
may deviate from the correct location.
ELK0193D
Straight roads
When driving on a long, straight road and
slow curve without stopping, map-matching does not work effectively enough and
distance errors may accumulate. As a
result, the vehicle mark may deviate from
the correct location when the vehicle is
turned at a corner.

Zigzag roads
When driving on a zigzag road, the map
may be matched to other roads in the similar direction nearby at every turn, and the
vehicle mark may deviate from the correct

Roads laid out in a grid pattern
When driving where roads are laid out in a
grid pattern, or where many roads are running in the similar direction nearby, the
map may be matched to them by mistake
and the vehicle mark may deviate from the
correct location.

Abusive driving
Driving condition
Remarks (correction, etc.)
If the vehicle is driven just after the engine
is started when the gyroscope (angular
speed sensor) correction is not completed,
the vehicle can lose its direction and may
have deviated from the correct location.
Wait for a short while before
driving after starting the engine.
When driving long distances without stopping, direction errors may accumulate, and
the current-location mark may deviate from
the correct road.
Stop and adjust the orientation.
Spinning the wheels or engaging in other
kinds of abusive driving may result in the
system being unable perform correct
detection, and may cause the vehicle mark
to deviate from the correct road.
If after travelling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if necessary, direction correction.
If the accuracy of location settings is poor,
accuracy may be reduced when the correct
road cannot be found, particularly in places
where there are many roads.
Enter in the road displayed on
the screen with an accuracy of
approx. 1mm.
Caution: Whenever possible,
use detailed map for the correction.
If the accuracy of location settings during
correction is poor, accuracy may be
reduced afterwards.
Perform direction correction.

CURRENT-LOCATION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG
In the following cases, the current-location mark may appear on completely different position in the map
depending on the GPS satellite signal receiving conditions. In this case, perform location correction and direction correction.
●
When location correction has not been done
–
If the receiving conditions of the GPS satellite signal is poor, or if the current-location mark becomes out of
place, it may move to a completely different location and not come back if location correction is not done.
The position will be corrected if the GPS signal can be received.
●
When the vehicle has traveled by ferry, or when the vehicle has been towed
–
Because calculation of the current location cannot be done when travelling with the ignition OFF, for
example when traveling by ferry or when being towed, the location before travel is displayed. If the precise
location can be detected with GPS, the location will be corrected.
CURRENT-LOCATION MARK JUMPS
In the following cases, the current-location mark may appear to jump as a result of automatic correction of the
current location.
●
When map-matching has been done
–
If the current location and the current-location mark are different when map-matching is done, the currentlocation mark may seem to jump. At this time, the location may be “corrected” to the wrong road or to a
location which is not on a road.
●
When GPS location correction has been done
–
If the current location and the current-location mark are different when the location is corrected using GPS
measurements, the current-location mark may seem to jump. At this time, the location may be “corrected”
to a location which is not on a road.

NAVIGATION SYSTEM
CURRENT-LOCATION MARK IS IN A RIVER OR SEA
The navigation system moves the current-location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
A
WHEN DRIVING ON SAME ROAD, SOMETIMES CURRENT-LOCATION MARK IS IN RIGHT
PLACE AND SOMETIMES IT IS WRONG PLACE
B
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.
C
LOCATION CORRECTION BY MAP-MATCHING IS SLOW
●
●
The map-matching function needs to refer to the data of the surrounding area. It is necessary to drive
some distance for the function to work.
Because map-matching operates on this principle, when there are many roads running in similar directions in the surrounding area, no matching determination may be made. The location may not be corrected until some special feature is found.
ALTHOUGH GPS RECEIVING DISPLAY IS GREEN, VEHICLE MARK DOES NOT RETURN TO
CORRECT LOCATION
●
●
●
The GPS accuracy has an error of approximately 10 m (30 ft). In some cases the current-location mark
may not be on the correct street, even when GPS location-correction is done.
The navigation system compares the results of GPS location detection with the results from map-matching location detection. The one which is determined to have higher accuracy is used.
GPS location correction may not be performed when the vehicle is stopped.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS008R5
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

BCM (BODY CONTROL MODULE)
System Description
●
PFP:284B2
A
EKS008R6
BCM (body control module) controls the operation of various electrical units installed on the vehicle.
BCM FUNCTION
B
BCM has a combination switch reading function for reading the operation of combination switches (light, wiper
washer, turn signal) in addition to the function for controlling the operation of various electrical components.
Also, it functions as an interface that receives signals from the front air control, and sends signals to ECM
using CAN communication.
C
COMBINATION SWITCH READING FUNCTION
1.
2.
Description
● BCM reads combination switch (light, wiper) status, and controls various electrical components according to the results.
● BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five input terminals (INPUT 1-5).
Operation description
● BCM activates transistors of output terminals (OUTPUT 1-5) periodically and allows current to flow in
turn.
● If any (1 or more) of the switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals (INPUT 1-5) becomes active.
● At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When
voltage of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects
voltage change and BCM determines that switch is ON.

LIIA1324E
NOTE:
Headlamp has a dual system switch.
4.
Example operation: (When lighting switch 1st position turned ON)
● When lighting switch 1st position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.
● When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges lighting
switch 1st position is ON. Then BCM sends tail lamp ON signal to IPDM E/R using CAN communication.
● When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5 and recognizes that lighting switch 1st position is continuously ON.

NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore, after a switch is turned ON,
electrical loads are activated with a time delay. But this time delay is so short that it cannot be noticed.
J
Operation mode
● Combination switch reading function has operation modes as follows:
BCS
Normal status
● When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.

Revision: November 2006
BCS-5
2006 Altima
BCM (BODY CONTROL MODULE)
●
When BCM is in sleep mode, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low-current-consumption mode. OUTPUTS (2, 3, and 4) turn ON-OFF at 60 ms intervals, and receives lighting
switch input only.
WKIA4093E
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information through the two communication lines (CAN-L, CAN-H)
connecting the various control units in the system. Each control unit transmits/receives data, but selectively
reads required data only.
BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
● With ignition switch ON, CAN communicates with other control units normally.
● Control by BCM is being operated properly.
● When ignition switch is OFF, switching to sleep mode is possible.
● Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status
● This status shuts down CAN communication when ignition switch is turned OFF.
● It transmits sleep request signal to IPDM E/R and combination meter.
● Two seconds after CAN communication of all control units stops, CAN communication switches to inactive status.
3. CAN communication inactive status
● With ignition switch OFF, CAN communication is not active.
● With ignition switch OFF, control performed only by BCM is active.
● Three seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS003H8
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for work
●
●
EIS003H9
After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check
their operation.
Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to BL-10, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
●
The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
●
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.
●
After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
●
Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
●
Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
●
Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
●
Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
●
Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
●
Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
●
Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
●
Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.
●
Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
●
Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
●
If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.

E
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
F
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1.

●
●
●
●
●
G
Narrow down the noise to a general area.To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear: J-39565 and mechanic's stethoscope).
Narrow down the noise to a more specific area and identify the cause of the noise by:
H
removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be broken or lost during the repair, resulting in the creation of new noise.
BL
tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.
feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the J
noise.
placing a piece of paper between components that you suspect are causing the noise.
K
looking for loose components and contact marks.
Refer to BL-8, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
If the cause is a loose component, tighten the component securely.
●
If the cause is insufficient clearance between components:
–
separate components by repositioning or loosening and retightening the component, if possible.
–
insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through your authorized NISSAN
Parts Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISSAN Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle Troubleshooting
EIS00487
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise.

TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise.
SUNROOF/HEADLINING
A
B
C
D
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
E
F
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lense loose.
3. Loose screws at console attachment points.
SEATS
G
H
BL
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
J
K
L
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

ID Code Entry Procedure
EIS003IN
A
KEYFOB ID SET UP WITH CONSULT-II
NOTE:
●
If a keyfob is lost, the ID code of the lost keyfob must be erased to prevent unauthorized use. A
specific ID code can be erased with CONSULT-II. However, when the ID code of a lost keyfob is not
known, all controller ID codes should be erased. After all ID codes are erased, the ID codes of all
remaining and/or new keyfobs must be re-registered.
●
When registering an additional keyfob, the existing ID codes in memory may or may not be erased.
If five ID codes are stored in memory when an additional code is registered, only the oldest code is
erased. If less than five codes are stored in memory when an additional code is registered, the
new ID code is added and no ID codes are erased.
●
Entry of a maximum of five ID codes is allowed. When more than five codes are entered, the oldest
ID code will be erased.
●
Even if the same ID code that is already in memory is input, the same ID code can be entered. The
code is counted as an additional code.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communications.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the

To erase all ID codes in memory, register one ID code (keyfob) five times. After all ID codes are erased,
the ID codes of all remaining and/or new keyfobs must be re-registered.
●
When registering an additional keyfob, the existing ID codes in memory may or may not be erased. If five
ID codes are stored in memory, when an additional code is registered, only the oldest code is erased. If
less than five ID codes are stored in memory, when an additional ID code is registered, the new ID code is
added and no ID codes are erased.
●
If you need to activate more than two additional new keyfobs, repeat the procedure “Additional ID code
entry” for each new keyfob.
●
Entry of maximum five ID codes is allowed. When more than five ID codes are entered, the oldest ID code
will be erased.
●
Even if same ID code that is already in the memory is input, the same ID code can be entered. The code
is counted as an additional code.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
System Description
EIS003J7
A
DESCRIPTION
Setting the vehicle security system
Disarmed phase
●
When the vehicle is being driven or when doors or trunk lid is open, the vehicle security system is set in
the disarmed phase on the assumption that the owner is inside or near the vehicle.
Pre-armed phase and armed phase
●
The vehicle security system turns into the "pre-armed" phase when trunk lid and all doors are closed and
locked by electronic key. The security indicator lamp illuminates for 30 seconds. Then, the system automatically shifts into the "armed" phase.
B
C
D
Canceling the set vehicle security system
When one of the following operations is performed, the armed phase is canceled.
1. Unlock the doors with the key or the keyfob.
2. Open the trunk lid with the key or the keyfob. When the trunk lid is closed after opening the trunk lid with
the keyfob, the system returns to the armed phase.
E
Activating the alarm operation of the vehicle security system
F
Make sure the system is in the armed phase.
When one of the following operations is performed, the system sounds the horns and flashes the head-lamps
for about 50 seconds.
1. Any door is opened before unlocking door with key or keyfob.
2. Door is unlocked without using key or keyfob.
3. Trunk lid is opened without using key or keyfob.

H
POWER SUPPLY
Power is supplied at all times
●
through 10A fuse [No.19, located in the fuse block (J/B)]
●
to security indicator lamp terminal 1
●
through 10A fuse [No. 21, located in the fuse block (J/B)]
●
to key switch and key lock solenoid terminal 3
●
to BCM terminal 57
●
through 50A fusible link (letter f , located in the fuse and fusible link box)
●
to BCM terminal 70.
With the ignition switch in the ACC or ON position, power is supplied
●
through 10A fuse [No. 6, located in the fuse block (J/B)]
●
to BCM terminal 11.
BL
J
K
L
INITIAL CONDITION TO ACTIVATE THE SYSTEM
M
The operation of the vehicle security system is controlled by the doors and trunk lid.
To activate the vehicle security system, BCM must receive signals indicating the doors and trunk lid are closed
and the doors are locked.
When a door is open, BCM terminal 12, 13, 47 or 48 receives a ground signal from each door switch.
When front door LH is unlocked, BCM terminal 22 receives a signal from terminal 14 of main power window
and door lock/unlock switch.
When front door RH is unlocked, BCM terminal 22 receives a signal from terminal 11 of power window and
door lock/unlock switch RH.
The IPDM E/R then sends a signal to the BCM through the CAN SYSTEM.
When the trunk lid is open, BCM terminal 42 receives a ground signal
●
from terminal 1 of the trunk lamp switch and trunk release solenoid
●
through body grounds B7 and B19.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
●
opening a door
●
opening the trunk lid
Revision: November 2006
BL-87
2006 Altima
VEHICLE SECURITY (THEFT WARNING) SYSTEM
unlocking door without using the key or keyfob.
The vehicle security system will be triggered once the system is in armed phase
●
when BCM receives a ground signal at terminals 12, 13, 47, 48 (door switch), 42 (trunk lamp and trunk
release solenoid switch).
Power is supplied at all times
●
to horn relay terminal 1
●
through 15A fuse (No. 25, located in fuse and fusible link box).
When the vehicle security system is triggered, ground is supplied intermittently
●
to headlamp high relay
●
from IPDM E/R terminal 51
●
to horn relay terminal 2.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
●
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or the trunk lid must be unlocked with the key or keyfob.
When the key is used to unlock the driver door, BCM terminal 22 receives signal
●
from terminal 14 of the main power window and door lock/unlock switch.
When the key is used to unlock the trunk lid, BCM terminal 41 receives a ground signal from terminal 1 of the
trunk key cylinder switch (unlock switch).
When the BCM receives either one of these signals or unlock signal from keyfob, the vehicle security system
is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Remote keyless entry system may or may not operate vehicle security system (horn and headlamps) as
required.
When the remote keyless entry system is triggered, ground is supplied intermittently
●
to headlamp high relay
●
from IPDM E/R terminal 51
●
to horn relay terminal 2.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from keyfob.

NVIS(NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS)
System Description
EIS003JR
NVIS (Nissan Vehicle Immobilizer System-NATS) has the following immobilizer functions:
●
Since only NVIS (NATS) ignition keys, whose IDs have been registered into the ECM and BCM, allow the
engine to run, operation of a stolen vehicle without a NVIS (NATS) registered key is prevented by NVIS
(NATS).
NVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS
(NATS).
●
All of the originally supplied ignition key IDs have been NVIS (NATS) registered.
If requested by the vehicle owner, a maximum of five key IDs can be registered into the NVIS (NATS)
components.
●
The security indicator blinks when the ignition switch is in OFF or ACC position. NVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.
●
When NVIS (NATS) detects trouble, the security indicator lamp lights up while ignition key is in the ON
position.
●
NVIS (NATS) trouble diagnoses, system initialization and additional registration of other NVIS (NATS)
ignition key IDs must be carried out using CONSULT-II hardware and CONSULT-II NVIS (NATS) software.
When NVIS (NATS) initialization has been completed, the ID of the inserted ignition key is automatically
NVIS (NATS) registered. Then, if necessary, additional registration of other NVIS (NATS) ignition key IDs
can be carried out.
Regarding the procedures of NVIS (NATS) initialization and NVIS (NATS) ignition key ID registration, refer
to CONSULT-II Operation Manual NATS-IVIS/NVIS.
●
When servicing a malfunction of the NVIS (NATS) (indicated by lighting up of Security Indicator
Lamp) or registering another NVIS (NATS) ignition key ID, it may be necessary to re-register original key identification. Therefore, be sure to receive ALL KEYS from vehicle owner.

ECM Re-communicating Function
EIS003JT
The following procedure can automatically perform re-communication of ECM and BCM, but only when the
ECM has been replaced with a new one which has never been energized on-board.
(In this step, initialization procedure by CONSULT-II is not necessary.)
NOTE:
●
When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual NATS-IVIS/NVIS.
●
If multiple keys are attached to the key holder, separate them before work.
●
Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Using a registered key (*1), turn ignition switch to ON.
*1: To perform this step, use the key that has been used before performing ECM replacement.
3. Maintain ignition switch in ON position for at least 5 seconds.
4. Turn ignition switch to OFF.
5. Start engine.
If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-II Operation Manual NATS-IVIS/NVIS and initialize control
unit.

Corrosion Protection
EIS003KA
DESCRIPTION
To provide improved corrosion prevention, the following anti-corrosive measures have been implemented in
NISSAN production plants. When repairing or replacing body panels, it is necessary to use the same anti-corrosive measures.
ANTI-CORROSIVE PRECOATED STEEL (GALVANNEALED STEEL)
To improve repairability and corrosion resistance, a new type of anticorrosive precoated steel sheet has been adopted replacing conventional zinc-coated steel sheet.
Galvannealed steel is electroplated and heated to form Zinc-iron
alloy, which provides excellent and long term corrosion resistance
with cationic electrodeposition primer.
PIIA0093E
Nissan Genuine Service Parts are fabricated from galvannealed steel. Therefore, it is recommended that
GENUINE NISSAN PARTS or equivalent be used for panel replacement to maintain the anti-corrosive performance built into the vehicle at the factory.
PHOSPHATE COATING TREATMENT AND CATIONIC ELECTRODEPOSITION PRIMER
A phosphate coating treatment and a cationic electrodeposition primer, which provide excellent corrosion protection, are employed on all body components.
CAUTION:
Confine paint removal during welding operations to an absolute
minimum.
PIIA0095E
Nissan Genuine Service Parts are also treated in the same manner. Therefore, it is recommended that GENUINE NISSAN PARTS or equivalent be used for panel replacement to maintain anti-corrosive performance built
into the vehicle at the factory.

BODY REPAIR
ANTI-CORROSIVE WAX
To improve corrosion resistance, anti-corrosive wax is applied inside the body sill and inside other closed sections. Accordingly, when replacing these parts, be sure to apply anti-corrosive wax to the appropriate areas of
the new parts. Select an excellent anti-corrosive wax which will penetrate after application and has a long shelf
life.

UNDERCOATING
The underside of the floor and wheelhouse are undercoated to prevent rust, vibration, noise and stone chipping. Therefore, when such a panel is replaced or repaired, apply undercoating to that part. Use an undercoating which is rust preventive, soundproof, vibration-proof, shock-resistant, adhesive, and durable.
Precautions in undercoating
1.
2.
3.
4.
Do not apply undercoating to any place unless specified (such as the areas above the muffler and three
way catalyst which are subjected to heat).
Do not undercoat the exhaust pipe or other parts which become hot.
Do not undercoat rotating parts.
Apply bitumen wax after applying undercoating.

Precautions in Repairing High Strength Steel
EIS003KF
High strength steel is used for body panels in order to reduce vehicle weight.
Accordingly, precautions in repairing automotive bodies made of high strength steel are described below:
HIGH STRENGTH STEEL (HSS) USED IN NISSAN VEHICLES
Tensile strength
373 N/mm2
(38kg/mm2 ,54klb/sq in)
785-981 N/mm2
(80-100kg/mm2

●

C
D
E
SP130 is the most commonly used HSS.
SP150 HSS is used only on parts that require much more strength.
F
Read the following precautions when repairing HSS:
1. Additional points to consider
● The repair of reinforcements (such as side members) by heating is not recommended since it may weaken the component.
When heating is unavoidable, do not heat HSS parts above
550°C (1,022°F).
Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appropriate.)
G
H
BL
PIIA0115E
●
When straightening body panels, use caution in pulling any
HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.
J
K
L
M
PIIA0116E
●
When cutting HSS panels, avoid gas (torch) cutting if possible. Instead, use a saw to avoid weakening surrounding areas
due to heat. If gas (torch) cutting is unavoidable, allow a minimum margin of 50 mm (1.97in).
PIIA0117E
Revision: November 2006
BL-155
2006 Altima
BODY REPAIR
●
When welding HSS panels, use spot welding whenever possible in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use M.I.G. welding. Do not use
gas (torch) welding because it is inferior in welding strength.
PIIA0144E
●
●
2.
The spot weld on HSS panels is harder than that of an ordinary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a
low speed high torque drill (1,000 to 1,200 rpm) to increase
drill bit durability and facilitate the operation.
SP150 HSS panels with a tensile strength of 785 to 981 N/
mm2 (80 to 100 kg/mm2 , 114 to 142 klb/sq in), used as reinforcement in the door guard beams, is too strong to repair.
When these HSS parts are damaged, the outer panels also
sustain substantial damage; therefore, the assembly parts
must be replaced.
PIIA0145E
Precautions in spot welding HSS
This work should be performed under standard working conditions. Always note the following when spot welding HSS:
● The electrode tip diameter must be sized properly according
to the metal thickness.
PIIA0146E
●
The panel surfaces must fit flush to each other, leaving no
gaps.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EFS007AO
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
BR
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
G
Precautions for Brake System
EFS0045K
Always use new brake fluid. Refer to MA-12, "RECOMMENDED FLUIDS AND LUBRICANTS" .
●
Never reuse drained brake fluid.
●
Be careful not to splash brake fluid on painted areas.
●
To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean
brake fluid.
●
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic
system.
●
Use flare nut wrench when removing and installing brake
tube.
●
Always tighten brake lines to specified torque when installing.
●
Burnish the brake contact surfaces after refinishing or
replacing drums or rotors, after replacing pads or linings,
or if a soft pedal occurs at very low mileage.
WARNING:
●
Clean brake pads and shoes with a waste cloth, then wipe
with a dust collector.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EFS0046S
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
BRC
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
G
Precautions for Brake System
EFS0046T
CAUTION:
●
Refer to MA-12, "RECOMMENDED FLUIDS AND LUBRICANTS" for recommended brake fluid.
●
Never reuse drained brake fluid.
●
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
●
To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
●
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic
system.
●
Use flare nut wrench when removing and installing brake
tube.
●
Brake system is an important safety part. If a brake fluid
leak is detected, always disassemble the affected part. If a
malfunction is detected, replace part with a new one.
●
Before working, turn ignition switch OFF and disconnect
electrical connector of ABS actuator and electric unit (control unit) or battery terminals.
●
Always torque brake lines when installing.
●
Burnish the brake contact surfaces after refinishing or
SBR686C
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to BR-26, "Brake Burnishing Procedure" .
WARNING:
●
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.

PURPOSE
The Anti-lock Brake System (ABS) consists of electronic and hydraulic components. It allows for control of
braking force so that locking of the wheels can be avoided.
The ABS:
●
Ensures proper tracking performance through steering wheel operation.
●
Enables obstacles to be avoided through steering wheel operation.
●
Ensures vehicle stability by preventing flat spins.
●
●
C
D
OPERATION
●
B
When the vehicle speed is less than 10 km/h (6 MPH) this system does not work.
The ABS has self-test capabilities. The system turns on the ABS warning lamp for 2 seconds after turning
the ignition switch ON. The system performs another test the first time the vehicle reaches 6 km/h (4 E
MPH). A mechanical noise may be heard as the ABS performs a self-test. This is a normal part of the selftest feature. If a malfunction is found during this check, the ABS warning lamp will come on.
BRC
During ABS operation, a mechanical noise may be heard. This is a normal condition.
Fail Safe
EFS0046Y
If trouble occurs in the ABS, the ABS warning lamp in the combination meter comes on. At the same time, the
vehicle stops the ABS control and braking becomes the same as that of a vehicle without ABS.

Control Unit
EFS00471
The control unit computes the wheel rotating speed by the signal
sent from the sensor. Then it supplies a DC current to the actuator
solenoid valve. It also controls ON-OFF operation of the solenoid
valve relay and motor relay. If any electrical malfunction should be
detected in the system, the control unit causes the warning lamp to
turn on. In this condition, the ABS will be deactivated by the control
unit, and the vehicle's brake system reverts to normal operation.

The ABS actuator and electric unit (control unit) contains:
●
An electric motor and pump
●
Two relays
●
Eight solenoid valves, each inlet and outlet for
— LH front
— RH front
— LH rear
— RH rear
●

EFS00474
INTRODUCTION
The ABS has an electronic control unit to control major functions.
The control unit accepts input signals from sensors and controls
operation of the actuator. It is also important to check for conventional problems such as air leaks in the booster or lines, lack of
brake fluid, or other problems with the brake system.
It is much more difficult to diagnose a problem that occurs intermittently rather than continuously. Most intermittent problems are
caused by poor electrical connections or faulty wiring. In this case,
careful checking of suspicious circuits may help prevent the replacement of good parts.
A visual check only may not find the cause of the problem, so a road
test should be performed.
Before undertaking actual checks, take just a few minutes to talk with
a customer who approaches with an ABS complaint. The customer
is a very good source of information on such problems, especially
intermittent ones. Through the talks with the customer, find out what
symptoms are present and under what conditions they occur.
Start your diagnosis by looking for “conventional” problems first. This
is one of the best ways to troubleshoot brake problems on an ABS
controlled vehicle. Also check related Service Bulletins for information.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EFS0047U
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
BRC
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

EFS0047Z
PURPOSE
The Anti-lock Brake System (ABS) consists of electronic and hydraulic components. It allows for control of
braking force so that locking of the wheels can be avoided.
The ABS:
●
Ensures proper tracking performance through steering wheel operation.
●
Enables obstacles to be avoided through steering wheel operation.
●
Ensures vehicle stability by preventing flat spins.
●
●
C
D
ABS (ANTI-LOCK BRAKE SYSTEM) OPERATION
●
B
When the vehicle speed is less than 10 km/h (6 MPH) this system does not work.
The ABS has self-test capabilities. The system turns on the ABS warning lamp for 2 seconds after turning
the ignition switch ON. The system performs another test the first time the vehicle reaches 6 km/h (4 E
MPH). A mechanical noise may be heard as the ABS performs a self-test. This is a normal part of the selftest feature. If a malfunction is found during this check, the ABS warning lamp will come on.
BRC
During ABS operation, a mechanical noise may be heard. This is a normal condition.
TCS (TRACTION CONTROL SYSTEM) OPERATION
●
●
●
●
●
This system is designed to limit wheel slip during acceleration by changing the transmission shift schedule
(with A/T) and cutting fuel to selected engine cylinders.
The ABS actuator and electric unit (control unit) detects drive wheel slip by comparing wheel speed signals from all 4 wheels. The ABS actuator and electric unit (control unit) will then determine the desired
torque reduction needed to minimize wheel spin.
The torque reduction by the ABS actuator and electric unit (control unit) may result in a combination of
transmission shift timing adjustments (with A/T) and fuel cutoff.
The torque reduction is sent from the ABS actuator and electric unit (control unit) through the CAN (Controller Area Network) lines to the TCM (with A/T) and the ECM. The ECM will cut fuel and/or the TCM will
change transmission shift schedule to achieve torque reduction.
The TCS will be enabled when the TCS OFF switch is in the ON position (TCS OFF indicator not illuminated), and if the catalytic converter temperature is within the normal operating range.
During TCS operation, the system informs the driver of system operation by flashing the SLIP indicator
lamp.
This system has a self-diagnostic function. When the ignition switch is initially turned ON, the SLIP indicator lamp and TCS OFF indicator lamp will illuminate. If the ABS/TCS system is operating correctly, both
indicator lamps will go out as soon as the engine starts.
The TCS OFF switch cancels the TCS function. The TCS OFF indicator lamp then illuminates to indicate
that the TCS system is not operating.
This system utilizes a fuel-cut function to control drive torque. If fuel cut continues for an extended period
of time during high-speed operation, the catalyst may melt and deteriorate. During continued TCS operation, the system will sometimes suspend the drive torque control function, preventing catalyst damage.
Fail Safe
EFS00480
If trouble occurs in the ABS, the ABS warning lamp in the combination meter will turn on. At the same time, the
ABS actuator and electric unit (control unit) will disable ABS control, and braking becomes the same as that of
a vehicle without ABS.

ABS FUNCTION
The control unit computes the wheel rotating speed by the signal
sent from the sensor. Then it supplies a DC current to the actuator
solenoid valve. It also controls ON-OFF operation of the valve relay
and motor relay. If any electrical malfunction should be detected in
the system, the warning lamp is turned on. In this condition, the ABS
will be disabled, and the vehicle's brake system reverts to normal
operation.

J
K

WFIA0267E
M
TCS FUNCTION
Drive wheel slippage is determined by comparing speed signals from
all 4 wheels. When the wheel slip becomes excessive, the TCS
operates, causing the SLIP indicator lamp to flash. At the same time,
a signal requesting a change in the shift schedule will be sent to the
TCM (with A/T) and a fuel-cut signal is sent to the ECM. When the
TCS OFF switch is used to cancel TCS function, the TCS OFF indicator lamp will light. (TCS does not activate.) In case of a malfunction in the TCS, both the SLIP indicator lamp and the TCS OFF
indicator lamp will light, while shutting down the TCS system operation. The vehicle will operate in the same way as a vehicle not
equipped with TCS.

EFS00485
The front wheel sensor units consist of a gear-shaped sensor rotor
and a sensor element. The element contains a magnet around which
a coil is wound. The front wheel sensors are installed on the front of
the wheel knuckles. As the wheel rotates, the sensor generates a
square-wave signal. The frequency increases as the wheel speed
increases.
LBR333
The rear wheel sensor units consist of wheel hubs with a series of
internal magnets and a sensor element. The rear wheel sensors are
installed on the inner side of the wheel knuckles. As the wheel
rotates, the sensor generates a square-wave signal. The frequency
increases as the wheel speed increases.

INTRODUCTION
The ABS/TCS has an electronic control unit to control major functions. The control unit accepts input signals from sensors and controls actuator operation. It is also important to check for conventional
problems such as air leaks in the booster or lines, lack of brake fluid,
or other problems with the brake system.
It is much more difficult to diagnose a problem that occurs intermittently rather than continuously. Most intermittent problems are
caused by poor electrical connections or faulty wiring. In this case,
careful checking of suspicious circuits may help prevent the replacement of good parts.
A visual check only may not find the cause of the problem, so a road
test should be performed.
Before undertaking actual checks, take just a few minutes to talk with
a customer who approaches with an ABS/TCS complaint. The customer is a very good source of information on such problems, especially intermittent ones. Through the talks with the customer, find out
what symptoms are present and under what conditions they occur.
Start your diagnosis by looking for “conventional” problems first. This
is one of the best ways to troubleshoot brake problems on an ABS/
TCS controlled vehicle. Also check related Service Bulletins for information.

After 3.0 seconds, the SLIP indicator lamp starts flashing to indicate the malfunction code No. (See NOTE.)
Verify the location of the malfunction with the malfunction code
chart. Refer to BRC-64, "SELF-DIAGNOSTIC RESULTS
MODE" . Then make the necessary repairs following the diagnostic procedures.
After the malfunctions are repaired, erase the malfunction codes
stored in the control unit. Refer to BRC-70, "HOW TO ERASE
SELF-DIAGNOSTIC RESULTS (MALFUNCTION CODES)" .
Repeat the self-diagnostic procedure to verify that the malfunction codes have been erased.
Disconnect the data link connector terminal 9 from ground. The
self-diagnostic results mode is now complete.
10. Verify that the ABS warning lamp, TCS OFF indicator lamp and
SLIP indicator lamp remain off after driving vehicle over 30 km/h
(19 MPH) for at least one minute.
11. After making certain that the ABS warning lamp, TCS OFF indicator lamp and SLIP indicator lamp do not come on, test the
ABS/TCS in a safe area to verify that it functions properly.
NOTE:
The indication terminates after five minutes.
However, when the ignition switch is turned from OFF to ON, the
SLIP indication starts flashing again. The TCS OFF indicator
lamp and ABS warning lamp remain lighted.

3.
Determine the code No. by counting the number of times the ABS warning lamp or SLIP indicator lamp
flashes on and off.
When several malfunctions occur at one time, up to three code numbers can be stored; the latest malfunction will be indicated first.
The indication begins with the start code 12. After that, a maximum of three code numbers appear in the
order of the latest one first. The indication then returns to the start code 12 and the sequence is repeated
(the indication will stay on for five minutes at the most).

HOW TO ERASE SELF-DIAGNOSTIC RESULTS (MALFUNCTION CODES)
1.
Disconnect data link connector terminal 9 from ground (ABS
warning lamp will stay lit).
2. Within 12.5 seconds, ground the data link connector terminal 9
three times. Each terminal ground must last more than 1 second. The ABS warning lamp turns off after the erase operation
has been completed.
3. Perform self-diagnosis again. Refer to BRC-22, "SELF-DIAGNOSIS PROCEDURE" . Only the start code should appear, no
malfunction codes.
After the erase operation is completed, it is necessary to repeat
the self-diagnostic procedure to verify that malfunction codes
no longer appear. Only the start code (12) should be indicated
when erase operation is completed and system is functioning normally.
NOTE:
The TCS OFF indicator lamp and ABS warning lamp remain on.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS00IYV
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions
ECS00939
Recommended fluid is brake fluid “DOT 3”.
●
Never reuse drained brake fluid.
●
Be careful not to splash brake fluid on painted areas.
●
When removing and installing clutch piping, use Tool.
●
Use new brake fluid to clean or wash all parts of master cylinder and operating cylinder.
●
Never use mineral oils such as gasoline or kerosene. It will
ruin the rubber parts of the hydraulic system.
WARNING:
After cleaning clutch disc, wipe it with a dust collector. Do not
use compressed air.

Check to see if the clutch pedal clevis pin floats freely in the bore
of the clutch pedal. It should not be bound by the clevis or clutch
pedal.
If the pin is not free, check that the ASCD switch or pedal stopper bolt is not applying pressure to the clutch pedal causing the
pin to bind. To adjust, loosen the ASCD switch or pedal stopper
bolt lock nut and turn the ASCD switch or pedal stopper bolt.
Tighten the lock nut.
Verify that the clutch pedal clevis pin floats freely in the bore of
the clutch pedal. It should not be bound by the clevis or clutch
pedal.
If the pin is still not free, remove the pin and check for deformation or damage. Replace the pin if necessary. Leave the pin
removed for step 2.
Check the clutch pedal stroke for free range of movement.
With the clutch pedal clevis pin removed, manually move the
pedal up and down to determine if it moves freely.
If any sticking is noted, replace the related parts (clutch pedal,
pedal bracket, assist spring and bushing). Reassemble the
pedal and re-verify that the clevis pin floats freely in the bore of
the pedal.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EBS00J7B
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along CO
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
F
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

CAUTION:
The compressed air supply must be equipped with an air dryer.
The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open
the ball valve on the refill hose slightly. Coolant will be visible rising in the refill hose. Once the refill hose is
full of coolant, close the ball valve. This will purge any air trapped in the refill hose.
Continue to draw the vacuum until the gauge reaches 28 inches
of vacuum. The gauge may not reach 28 inches in high altitude
locations, refer to the vacuum specifications based on the altitude above sea level.
Altitude above sea level

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EBS00J7V
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along CO
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
F
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EKS008OV
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

EKS008Q9
FUNCTION
The board computer can indicate the following items.
●
Outside air temperature
●
DTE (distance to empty) (without NAVI)
●
Trip distance
●
Trip time (without NAVI)
●
Average fuel consumption (without NAVI)
●
Average vehicle speed (without NAVI)
B
C
D
OUTSIDE AIR TEMPERATURE INDICATION
The outside air temperature indication is displayed while the ignition switch is in the ON position.
Signal is supplied
●
through ambient sensor terminal 1
●
to combination meter (board computer) terminal 33.
Indication range is between -30 and 55°C (-22 and 131°F). When outside temperature is less than 3°C (37°F),
display shows ICY. In this case, the display will change to the outside air temperature mode even though the
display is showing a different mode. When outside temperature is more than 55°C (131°F), indication will be
blank. The indicated temperature is not affected by engine heat. It changes only when one of the following
conditions exists.
●
When vehicle speed is more than 20 km/h (12 MPH).
●
The ignition switch has been turned OFF for more than 3.5 hours.
●
When outside air temperature is less than the indicated temperature.
DTE (DISTANCE TO EMPTY) INDICATION
E
F
G
H
I
The range indication provides the driver with an estimation of the distance that can be driven before refueling.
The range is calculated by signals from the fuel level sensor unit (fuel remaining), ECM (fuel consumption)
and vehicle speed sensor (without TCS or 5-speed A/T) or the ABS actuator and electric unit (with TCS or 5- J
speed A/T). The indication will be refreshed every 30 seconds. When fuel remaining is less than approximately 10 (2 5/8 US gal, 2 1/4 Imp gal), the indication will blink as a warning. If the fuel remaining is less than
approximately 8 (2 1/8 US gal, 1 3/4 Imp gal), the indication will show "---". In this case, the display will
DI
change to the DTE mode even though the display is showing a different mode. When the battery is disconnected and reconnected, DTE mode will display "---" until the vehicle is driven 500 miles (804.5 km).
TRIP DISTANCE
L
Trip distance is calculated by signal from the vehicle speed sensor (without TCS or 5-speed A/T) or the ABS
actuator and electric unit (with TCS or 5-speed A/T). If trip distance is reset, trip time will be reset at the same
time.
TRIP TIME
Trip time displays cumulative ignition switch ON time. If trip time is reset, trip distance will be reset at the same
time.
AVERAGE FUEL CONSUMPTION
Average fuel consumption indication is calculated by signals from the vehicle speed sensor (without TCS or 5speed A/T) or the ABS actuator and electric unit (with TCS or 5-speed A/T) and the ECM (fuel consumption).
The indication will be refreshed every 30 seconds.
AVERAGE VEHICLE SPEED
Average vehicle speed indication is calculated by running distance and running time. The indication will be
refreshed every 30 seconds. If average vehicle speed is reset, average fuel consumption will be reset at the
same time. After resetting, the display will show "---" for 30 seconds.
HOW TO CHANGE/RESET INDICATION
Indication can be changed in the following order by momentarily depressing the board computer switch or the
board computer steering switch.
Revision: November 2006
DI-61
2006 Altima
M
BOARD COMPUTER
Outside air temperature → dte (without NAVI) → Average fuel consumption (without NAVI) → Average vehicle
speed (without NAVI) → Trip time (without NAVI) → Trip distance.
Holding the switch for more than 0.8 second will reset the indication of the currently displayed mode (trip distance, trip time, average vehicle speed or average fuel consumption).
NOTE:
After the display changes automatically, the indication can be changed to the last mode by pushing the board
computer switch or the board computer steering switch.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
UBS00IIV
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along EC
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
F
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
G
On Board Diagnostic (OBD) System of Engine and A/T
UBS002NU
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
●
Be sure to turn the ignition switch OFF and disconnect the battery ground cable before any repair
or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MIL to light up.
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
●
Certain systems and components, especially those related to OBD, may use a new style slidelocking type harness connector. For description and how to disconnect, refer to PG-66, "HARNESS CONNECTOR" .
●
Be sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MIL to light up due to the short circuit.
●
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to the malfunction of the fuel injection system, etc.
●
Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.
Precaution
●
●
●
●
UBS002NV
Always use a 12 volt battery as power source.
Do not attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness connector, turn ignition switch OFF and disconnect battery
ground cable. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned OFF.
Before removing parts, turn ignition switch OFF and then
disconnect battery ground cable.

A poor connection can cause an extremely high (surge)
voltage to develop in coil and condenser, thus resulting in
damage to ICs.
Keep engine control system harness at least 10 cm (4 in)
away from adjacent harness, to prevent engine control system malfunctions due to receiving external noise, degraded
operation of ICs, etc.
Keep engine control system parts and harness dry.
Before replacing ECM, perform “ECM Terminals and Reference Value” inspection and make sure ECM functions properly. Refer to EC-109 .
Handle mass air flow sensor carefully to avoid damage.
Do not disassemble mass air flow sensor.
Do not clean mass air flow sensor with any type of detergent.
Do not disassemble electric throttle control actuator.
Even a slight leak in the air intake system can cause serious incidents.
Do not shock or jar the camshaft position sensor (PHASE),

by input signals (for engine speed and intake air) from both the crankshaft position sensor and the mass air
flow sensor.

MIXTURE RATIO FEEDBACK CONTROL (CLOSED LOOP CONTROL)
PBIB3020E
The mixture ratio feedback system provides the best air-fuel mixture ratio for driveability and emission control.
The three way catalyst (manifold) can then better reduce CO, HC and NOx emissions. This system uses air
fuel ratio (A/F) sensor 1 in the exhaust manifold to monitor whether the engine operation is rich or lean. The
ECM adjusts the injection pulse width according to the sensor voltage signal. For more information about air
fuel ratio (A/F) sensor 1, refer to EC-228, "DTC P0131 A/F SENSOR 1" . This maintains the mixture ratio
within the range of stoichiometric (ideal air-fuel mixture).
This stage is referred to as the closed loop control condition.
Heated oxygen sensor 2 is located downstream of the three way catalyst (manifold). Even if the switching
characteristics of air fuel ratio (A/F) sensor 1 shift, the air-fuel ratio is controlled to stoichiometric by the signal
from heated oxygen sensor 2.
Open Loop Control
The open loop system condition refers to when the ECM detects any of the following conditions. Feedback
control stops in order to maintain stabilized fuel combustion.
●
Deceleration and acceleration
●
High-load, high-speed operation
●
Malfunction of air fuel ratio (A/F) sensor 1 or its circuit
●
Insufficient activation of air fuel ratio (A/F) sensor 1 at low engine coolant temperature
●
High engine coolant temperature
●
During warm-up
●
After shifting from N to D (A/T models)
●
When starting the engine
MIXTURE RATIO SELF-LEARNING CONTROL
The mixture ratio feedback control system monitors the mixture ratio signal transmitted from air fuel ratio (A/F)
sensor 1. This feedback signal is then sent to the ECM. The ECM controls the basic mixture ratio as close to
the theoretical mixture ratio as possible. However, the basic mixture ratio is not necessarily controlled as originally designed. Both manufacturing differences (i.e., mass air flow sensor hot wire) and characteristic
changes during operation (i.e., fuel injector clogging) directly affect mixture ratio.
Accordingly, the difference between the basic and theoretical mixture ratios is monitored in this system. This is
then computed in terms of “injection pulse duration” to automatically compensate for the difference between
the two ratios.
“Fuel trim” refers to the feedback compensation value compared against the basic injection duration. Fuel trim
includes short term fuel trim and long term fuel trim.
“Short term fuel trim” is the short-term fuel compensation used to maintain the mixture ratio at its theoretical
value. The signal from air fuel ratio (A/F) sensor 1 indicates whether the mixture ratio is RICH or LEAN compared to the theoretical value. The signal then triggers a reduction in fuel volume if the mixture ratio is rich, and
an increase in fuel volume if it is lean.
“Long term fuel trim” is overall fuel compensation carried out long-term to compensate for continual deviation
of the short term fuel trim from the central value. Such deviation will occur due to individual engine differences,
wear over time and changes in the usage environment.

Sequential Multiport Fuel Injection System
Fuel is injected into each cylinder during each engine cycle according to the firing order. This system is used
when the engine is running.
Simultaneous Multiport Fuel Injection System
Fuel is injected simultaneously into all four cylinders twice each engine cycle. In other words, pulse signals of
the same width are simultaneously transmitted from the ECM.
The four fuel injectors will then receive the signals two times for each engine cycle.
This system is used when the engine is being started and/or if the fail-safe system (CPU) is operating.

BASIC ASCD SYSTEM
Refer to Owner's Manual for ASCD operating instructions.
Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at predetermined constant speed
without depressing accelerator pedal. Driver can set vehicle speed in advance between approximately 40 km/
h (25 MPH) and 144 km/h (89 MPH).
ECM controls throttle angle of electric throttle control actuator to regulate engine speed.
Operation status of ASCD is indicated by CRUISE indicator and SET indicator in combination meter. If any
malfunction occurs in ASCD system, it automatically deactivates control.
NOTE:
Always drive vehicle in safe manner according to traffic conditions and obey all traffic laws.
SET OPERATION
Press MAIN switch. (The CRUISE indicator in combination meter illuminates.)
When vehicle speed reaches a desired speed between approximately 40 km/h (25 MPH) and 144 km/h (89
MPH), press SET/COAST switch. (Then SET indicator in combination meter illuminates.)
ACCELERATE OPERATION
If the RESUME/ACCELERATE switch is depressed during cruise control driving, increase the vehicle speed
until the switch is released or vehicle speed reaches maximum speed controlled by the system.
And then ASCD will keep the new set speed.
CANCEL OPERATION
When any of following conditions exist, cruise operation will be canceled.
●
CANCEL switch is pressed
●
More than 2 switches at ASCD steering switch are pressed at the same time (Set speed will be cleared)
●

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

PBIB2037E
The evaporative emission system is used to reduce hydrocarbons emitted into the atmosphere from the fuel
system. This reduction of hydrocarbons is accomplished by activated charcoals in the EVAP canister.
The fuel vapor in the sealed fuel tank is led into the EVAP canister which contains activated carbon and the
vapor is stored there when the engine is not operating or when refueling to the fuel tank.
The vapor in the EVAP canister is purged by the air through the purge line to the intake manifold when the
engine is operating. EVAP canister purge volume control solenoid valve is controlled by ECM. When the
engine operates, the flow rate of vapor controlled by EVAP canister purge volume control solenoid valve is
proportionally regulated as the air flow increases.
EVAP canister purge volume control solenoid valve also shuts off the vapor purge line during decelerating and
idling.

System Description
PFP:00032
UBS00CFA
PBIB1387E
From the beginning of refueling, the air and vapor inside the fuel tank go through refueling EVAP vapor cut
valve and EVAP/ORVR line to the EVAP canister. The vapor is absorbed by the EVAP canister and the air is
released to the atmosphere.
When the refueling has reached the full level of the fuel tank, the refueling EVAP vapor cut valve is closed and
refueling is stopped because of auto shut-off. The vapor which was absorbed by the EVAP canister is purged
during driving.
WARNING:
When conducting inspections below, be sure to observe the following:
●
Put a “CAUTION: INFLAMMABLE” sign in workshop.
●
Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
●
Be sure to furnish the workshop with a CO2 fire extinguisher.
CAUTION:
●
Before removing fuel line parts, carry out the following procedures:
–
Put drained fuel in an explosion-proof container and put lid on securely.
–
Release fuel pressure from fuel line. Refer to EC-84, "FUEL PRESSURE RELEASE" .
–
Disconnect battery ground cable.
●
Always replace O-ring when the fuel gauge retainer is removed.
●
Do not kink or twist hose and tube when they are installed.
●
Do not tighten hose and clamps excessively to avoid damaging hoses.
●
After installation, run engine and check for fuel leaks at connection.
●
Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.

POSITIVE CRANKCASE VENTILATION
Description
PFP:11810
UBS0034D
SYSTEM DESCRIPTION
PBIB0492E
This system returns blow-by gas to the intake manifold.
The positive crankcase ventilation (PCV) valve is provided to conduct crankcase blow-by gas to the intake
manifold. During partial throttle operation of the engine, the intake manifold sucks the blow-by gas through the
PCV valve. Normally, the capacity of the valve is sufficient to handle any blow-by and a small amount of ventilating air. The ventilating air is then drawn from the air inlet tubes into the crankcase. In this process the air
passes through the hose connecting air inlet tubes to rocker cover. Under full-throttle condition, the manifold
vacuum is insufficient to draw the blow-by flow through the valve. The flow goes through the hose connection
in the reverse direction.
On vehicles with an excessively high blow-by, the valve does not
meet the requirement. This is because some of the flow will go
through the hose connection to the air inlet tubes under all conditions.

PCV (POSITIVE CRANKCASE VENTILATION) VALVE

*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator lamp (MIL) on the instrument panel lights up when the same malfunction is detected
in two consecutive trips (Two trip detection logic), or when the ECM enters fail-safe mode. (Refer to EC-96 .)
Two Trip Detection Logic
I
UBS002OE
When a malfunction is detected for the first time, 1st trip DTC and 1st trip Freeze Frame data are stored in the
ECM memory. The MIL will not light up at this stage. <1st trip>
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in
the ECM memory, and the MIL lights up. The MIL lights up at the same time when the DTC is stored. <2nd
trip> The “trip” in the “Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation. Specific on board diagnostic items will cause the ECM to light up or blink the MIL,
and store DTC and Freeze Frame data, even in the 1st trip, as shown below.

DTC AND 1ST TRIP DTC
The 1st trip DTC (whose number is the same as the DTC number) is displayed for the latest self-diagnostic
result obtained. If the ECM memory was cleared previously, and the 1st trip DTC did not reoccur, the 1st trip
DTC will not be displayed.
Revision: November 2006

2006 Altima
ON BOARD DIAGNOSTIC (OBD) SYSTEM
[QR]
If a malfunction is detected during the 1st trip, the 1st trip DTC is stored in the ECM memory. The MIL will not
light up (two trip detection logic). If the same malfunction is not detected in the 2nd trip (meeting the required A
driving pattern), the 1st trip DTC is cleared from the ECM memory. If the same malfunction is detected in the
2nd trip, both the 1st trip DTC and DTC are stored in the ECM memory and the MIL lights up. In other words,
the DTC is stored in the ECM memory and the MIL lights up when the same malfunction occurs in two consecEC
utive trips. If a 1st trip DTC is stored and a non-diagnostic operation is performed between the 1st and 2nd
trips, only the 1st trip DTC will continue to be stored. For malfunctions that blink or light up the MIL during the
1st trip, the DTC and 1st trip DTC are stored in the ECM memory.
Procedures for clearing the DTC and the 1st trip DTC from the ECM memory are described in EC-64, "HOW C
TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
For malfunctions in which 1st trip DTCs are displayed, refer to EC-54, "EMISSION-RELATED DIAGNOSTIC
INFORMATION ITEMS" . These items are required by legal regulations to continuously monitor the system/ D
component. In addition, the items monitored non-continuously are also displayed on CONSULT-II.
1st trip DTC is specified in Service $07 of SAE J1979. 1st trip DTC detection occurs without lighting up the MIL
and therefore does not warn the driver of a malfunction. However, 1st trip DTC detection will not prevent the
E
vehicle from being tested, for example during Inspection/Maintenance (I/M) tests.
When a 1st trip DTC is detected, check, print out or write down and erase (1st trip) DTC and Freeze Frame
data as specified in Work Flow procedure Step 2, refer to EC-89, "WORK FLOW" . Then perform DTC Confirmation Procedure or Overall Function Check to try to duplicate the malfunction. If the malfunction is dupli- F
cated, the item requires repair.
How to Read DTC and 1st Trip DTC
DTC and 1st trip DTC can be read by the following methods.
WITH CONSULT-II
WITH GST
CONSULT-II or GST (Generic Scan Tool) Examples: P0340, P1148, P1706, etc.
These DTCs are prescribed by SAE J2012.
(CONSULT-II also displays the malfunctioning component or system.)
NO TOOLS
The number of blinks of the MIL in the Diagnostic Test Mode II (Self-Diagnostic Results) indicates the DTC.
Example: 0340, 1148, 1706, etc.
These DTCs are controlled by NISSAN.
●
1st trip DTC No. is the same as DTC No.
●
Output of a DTC indicates a malfunction. However, GST or the Diagnostic Test Mode II do not indicate whether the malfunction is still occurring or has occurred in the past and has returned to normal. CONSULT-II can identify malfunction status as shown below. Therefore, using CONSULT-II (if
available) is recommended.
A sample of CONSULT-II display for DTC and 1st trip DTC is shown below. DTC or 1st trip DTC of a malfunction is displayed in SELF-DIAGNOSTIC RESULTS mode of CONSULT-II. Time data indicates how many times
the vehicle was driven after the last detection of a DTC.
If the DTC is being detected currently, the time data will be 0.
If a 1st trip DTC is stored in the ECM, the time data will be [1t].
PBIB0911E
FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA
The ECM records the driving conditions such as fuel system status, calculated load value, engine coolant temperature, short term fuel trim, long term fuel trim, engine speed, vehicle speed, base fuel schedule and intake
air temperature at the moment a malfunction is detected.
Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data.
The data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II or

GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
details, see EC-57, "FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA" .
Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the following priorities to update the data.
Priority
1
Items
Freeze frame data
Misfire — DTC: P0300 - P0304
Fuel Injection System Function — DTC: P0171, P0172
2
3
Except the above items (Includes A/T related items)
1st trip freeze frame data
For example, the EGR malfunction (Priority: 2) was detected and the freeze frame data was stored in the 2nd
trip. After that when the misfire (Priority: 1) is detected in another trip, the freeze frame data will be updated
from the EGR malfunction to the misfire. The 1st trip freeze frame data is updated each time a different malfunction is detected. There is no priority for 1st trip freeze frame data. However, once freeze frame data is
stored in the ECM memory, 1st trip freeze data is no longer stored (because only one freeze frame data or 1st
trip freeze frame data can be stored in the ECM). If freeze frame data is stored in the ECM memory and freeze
frame data with the same priority occurs later, the first (original) freeze frame data remains unchanged in the
ECM memory.
Both 1st trip freeze frame data and freeze frame data (along with the DTCs) are cleared when the ECM memory is erased. Procedures for clearing the ECM memory are described in EC-54, "EMISSION-RELATED
DIAGNOSTIC INFORMATION ITEMS" .
SYSTEM READINESS TEST (SRT) CODE
System Readiness Test (SRT) code is specified in Service $01 of SAE J1979.
As part of an enhanced emissions test for Inspection & Maintenance (I/M), certain states require the status of
SRT be used to indicate whether the ECM has completed self-diagnosis of major emission systems and components. Completion must be verified in order for the emissions inspection to proceed.
If a vehicle is rejected for a State emissions inspection due to one or more SRT items indicating “INCMP”, use
the information in this Service Manual to set the SRT to “CMPLT”.
In most cases the ECM will automatically complete its self-diagnosis cycle during normal usage, and the SRT
status will indicate “CMPLT” for each application system. Once set as “CMPLT”, the SRT status remains
“CMPLT” until the self-diagnosis memory is erased.
Occasionally, certain portions of the self-diagnostic test may not be completed as a result of the customer's
normal driving pattern; the SRT will indicate “INCMP” for these items.
NOTE:
The SRT will also indicate “INCMP” if the self-diagnosis memory is erased for any reason or if the ECM memory power supply is interrupted for several hours.
If, during the state emissions inspection, the SRT indicates “CMPLT” for all test items, the inspector will continue with the emissions test. However, if the SRT indicates “INCMP” for one or more of the SRT items the
vehicle is returned to the customer untested.
NOTE:
If MIL is ON during the state emissions inspection, the vehicle is also returned to the customer untested even
though the SRT indicates “CMPLT” for all test items. Therefore, it is important to check SRT (“CMPLT”) and
DTC (No DTCs) before the inspection.

When all SRT related self-diagnoses showed OK results in a single cycle (Ignition OFF-ON-OFF), the SRT will
indicate “CMPLT”. → Case 1 above
When all SRT related self-diagnoses showed OK results through several different cycles, the SRT will indicate
“CMPLT” at the time the respective self-diagnoses have at least one OK result. → Case 2 above
If one or more SRT related self-diagnoses showed NG results in 2 consecutive cycles, the SRT will also indicate “CMPLT”. → Case 3 above
The table above shows that the minimum number of cycles for setting SRT as “INCMP” is one (1) for each
self-diagnosis (Case 1 & 2) or two (2) for one of self-diagnoses (Case 3). However, in preparation for the state
emissions inspection, it is unnecessary for each self-diagnosis to be executed twice (Case 3) for the following
reasons:
●
The SRT will indicate “CMPLT” at the time the respective self-diagnoses have one (1) OK result.
●
The emissions inspection requires “CMPLT” of the SRT only with OK self-diagnosis results.
●
When, during SRT driving pattern, 1st trip DTC (NG) is detected prior to “CMPLT” of SRT, the self-diagnosis memory must be erased from ECM after repair.
●
If the 1st trip DTC is erased, all the SRT will indicate “INCMP”.

TEST VALUE AND TEST LIMIT (GST ONLY — NOT APPLICABLE TO CONSULT-II)
The following is the information specified in Service $06 of SAE J1979.
The test value is a parameter used to determine whether a system/circuit diagnostic test is “OK” or “NG” while
being monitored by the ECM during self-diagnosis. The test limit is a reference value which is specified as the
maximum or minimum value and is compared with the test value being monitored.
These data (test value and test limit) are specified by Test ID (TID) and Component ID (CID) and can be displayed on the GST screen.

HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION
How to Erase DTC
With CONSULT-II
The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELFDIAG RESULTS” mode with CONSULT-II.
If DTCs are displayed for both ECM and TCM (Transmission control module), they need to be erased individually from the ECM and TCM (Transmission control module).

DESCRIPTION
The MIL is located on the instrument panel.
1. The MIL will light up when the ignition switch is turned ON without the engine running. This is a bulb check.
If the MIL does not light up, refer to DI-31, "WARNING LAMPS"
, or see EC-610, "MIL AND DATA LINK CONNECTOR" .
2. When the engine is started, the MIL should go off.
If the MIL remains on, the on board diagnostic system has
detected an engine system malfunction.

MALFUNCTION
WARNING
This is a usual driving condition. When a malfunction is
detected twice in two consecutive driving cycles (two trip
detection logic), the MIL will light up to inform the driver
that a malfunction has been detected.
The following malfunctions will light up or blink the MIL in
the 1st trip.

When there is an open circuit on MIL circuit, the ECM cannot warn the driver by MIL lighting up when there is
malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as
NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by means
of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MIL circuit are detected, and demands the
driver to repair the malfunction.

When any SRT codes are not set, MIL may flash without DTC. For the details, refer to EC-61, "How to Display
SRT Status" .
HOW TO SWITCH DIAGNOSTIC TEST MODE
NOTE:
●
It is better to count the time accurately with a clock.
●
It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit
has a malfunction.
●
Always ECM returns to Diagnostic Test Mode I after ignition switch is turned OFF.

A particular trouble code can be identified by the number of four-digit numeral flashes. The “zero” is indicated
by the number of ten flashes. The “A” is indicated by the number of eleven flash. The length of time the
1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-second) - OFF (0.6-second)
cycle.
The 100th-digit numeral and lower digit numerals consist of a 0.3-second ON and 0.3-second OFF cycle.
A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-second OFF.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC 0000 refers to no malfunction. (See EC-15, "INDEX FOR DTC" )
How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
The DTC can be erased from the back-up memory in the ECM by depressing accelerator pedal. Refer to EC68, "How to Erase Diagnostic Test Mode II (Self-diagnostic Results)" .
●
If the battery is disconnected, the DTC will be lost from the backup memory within 24 hours.
●
Be careful not to erase the stored memory before starting trouble diagnoses.

When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data are
stored in the ECM memory.
When the same malfunction is detected in two consecutive trips, the DTC and the freeze frame data are
stored in the ECM memory, and the MIL will come on. For details, refer to EC-53, "Two Trip Detection
Logic" .
The MIL will go off after the vehicle is driven 3 times (driving pattern B) with no malfunction. The drive is
counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction
occurs while counting, the counter will reset.

EXPLANATION FOR DRIVING PATTERNS FOR “MISFIRE ”, “FUEL INJECTION SYSTEM”
Driving pattern B means the vehicle operation as follows:
All components and systems should be monitored at least once by the OBD system.
●
The B counter will be cleared when the malfunction is detected once regardless of the driving pattern.
●
The B counter will be counted up when driving pattern B is satisfied without any malfunction.
●
The MIL will go off when the B counter reaches 3. (*2 in “OBD SYSTEM OPERATION CHART”)
Driving pattern C means the vehicle operation as follows:
The following conditions should be satisfied at the same time:
Engine speed: (Engine speed in the freeze frame data) ±375 rpm
Calculated load value: (Calculated load value in the freeze frame data) x (1±0.1) [%]
Engine coolant temperature (T) condition:
●
When the freeze frame data shows lower than 70°C (158°F), “T” should be lower than 70°C (158°F).
●
When the freeze frame data shows higher than or equal to 70°C (158°F), “T” should be higher than or
equal to 70°C (158°F).
Example:
If the stored freeze frame data is as follows:
Engine speed: 850 rpm, Calculated load value: 30%, Engine coolant temperature: 80°C (176°F)
To be satisfied with driving pattern C, the vehicle should run under the following conditions:
Engine speed: 475 - 1,225 rpm, Calculated load value: 27 - 33%, Engine coolant temperature: more than 70°C
(158°F)
●
The C counter will be cleared when the malfunction is detected regardless of vehicle conditions above.
●
The C counter will be counted up when vehicle conditions above is satisfied without the same malfunction.
●
The DTC will not be displayed after C counter reaches 80.
●
The 1st trip DTC will be cleared when C counter is counted once without the same malfunction after DTC
is stored in ECM.

TROUBLE DIAGNOSIS
Trouble Diagnosis Introduction
PFP:00004
UBS002OJ
INTRODUCTION
The engine has an ECM to control major systems such as fuel control, ignition control, idle air control system, etc. The ECM accepts
input signals from sensors and instantly drives actuators. It is essential that both input and output signals are proper and stable. At the
same time, it is important that there are no malfunctions such as vacuum leaks, fouled spark plugs, or other malfunctions with the engine.
MEF036D
It is much more difficult to diagnose an incident that occurs intermittently rather than continuously. Most intermittent incidents are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replacement of good parts.
SEF233G
A visual check only may not find the cause of the incidents. A road
test with CONSULT-II (or GST) or a circuit tester connected should
be performed. Follow the WORK FLOW on EC-89 .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The customer can supply good information about such incidents, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A DIAGNOSTIC WORKSHEET like the
example on EC-93 should be used.
Start your diagnosis by looking for conventional malfunctions first.
This will help troubleshoot driveability malfunctions on an electronically controlled engine vehicle.

DIAGNOSTIC WORKSHEET
Description
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about an incident. It is
important to fully understand the symptoms or conditions for a customer complaint.
Utilize a diagnostic worksheet like the one on the next page in order
to organize all the information for troubleshooting.
Some conditions may cause the MIL to come on steady or blink and
DTC to be detected. Examples:
●
Vehicle ran out of fuel, which caused the engine to misfire.
●
Fuel filler cap was left off or incorrectly screwed on, allowing fuel
to evaporate into the atmosphere.

Fail-safe Chart
UBS002OL
When the DTC listed below is detected, the ECM enters fail-safe mode and the MIL lights up.
DTC No.
Detected items
Engine operating condition in fail-safe mode
P0102
P0103
Mass air flow sensor circuit
Engine speed will not rise more than 2,400 rpm due to the fuel cut.
P0117
P0118
Engine coolant temperature sensor circuit
Engine coolant temperature will be determined by ECM based on the time after turning
ignition switch ON or START.
CONSULT-II displays the engine coolant temperature decided by ECM.
Condition
Engine coolant temperature decided (CONSULTII display)
Just as ignition switch is turned
ON or START
40°C (104°F)
More than approx. 4 minutes after
ignition ON or START
80°C (176°F)
Except as shown above
40 - 80°C (104 - 176°F)
(Depends on the time)
When the fail-safe system for engine coolant temperature sensor is activated, the cooling fan operates while engine is running.
P0122
P0123
P0222
P0223
P2135
Throttle position sensor
The ECM controls the electric throttle control actuator in regulating the throttle opening
in order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.
P0643
Sensor power supply
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2100
P2103
Throttle control relay
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2101
Electric throttle control function
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2118
Throttle control motor
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2119
Electric throttle control actuator
(When electric throttle control actuator does not function properly due to the return
spring malfunction:)
ECM controls the electric throttle actuator by regulating the throttle opening around the
idle position. The engine speed will not rise more than 2,000 rpm.
(When throttle valve opening angle in fail-safe mode is not in specified range:)
ECM controls the electric throttle control actuator by regulating the throttle opening to
20 degrees or less.
(When ECM detects the throttle valve is stuck open:)
While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops,
the engine stalls.
The engine can restart in N or P (A/T), Neutral (M/T) position, and engine speed will
not exceed 1,000 rpm or more.
P2122
P2123
P2127
P2128
P2138
●
Accelerator pedal position
sensor
The ECM controls the electric throttle control actuator in regulating the throttle opening
in order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.
When there is an open circuit on MIL circuit, the ECM cannot warn the driver by MIL lighting up when
there is malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected
as NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by
means of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MIL circuit are detected, and demands
the driver to repair the malfunction.

TROUBLE DIAGNOSIS
[QR]
The malfunction will be identified on the CONSULT-II screen
in real time.
In other words, DTC/1st trip DTC and malfunction item will be
displayed if the malfunction is detected by ECM.
At the moment a malfunction is detected by ECM, “MONITOR” in “DATA MONITOR” screen is changed to “Recording
Data ... xx%” as shown at right, and the data after the malfunction detection is recorded. Then when the percentage
reached 100%, “REAL-TIME DIAG” screen is displayed. If
“STOP” is touched on the screen during “Recording Data ...
xx%”, “REAL-TIME DIAG” screen is also displayed.
The recording time after the malfunction detection and the
recording speed can be changed by “TRIGGER POINT” and
“Recording Speed”. Refer to CONSULT-II OPERATION MANUAL.
“MANU TRIG” (Manual trigger):
● DTC/1st trip DTC and malfunction item will not be displayed
automatically on CONSULT-II screen even though a malfunction is detected by ECM.
DATA MONITOR can be performed continuously even though
a malfunction is detected.

Operation
1.
“AUTO TRIG”
While trying to detect the DTC/1st trip DTC by performing the DTC Confirmation Procedure, be sure to
select to “DATA MONITOR (AUTO TRIG)” mode. You can confirm the malfunction at the moment it is
detected.
● While narrowing down the possible causes, CONSULT-II should be set in “DATA MONITOR (AUTO
TRIG)” mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, components and harness in the DTC Confirmation Procedure, the moment a malfunction is found the DTC/1st
trip DTC will be displayed. (Refer to “Incident Simulation Tests” in GI-27, "How to Perform Efficient
Diagnosis for an Electrical Incident" .)
“MANU TRIG”
● If the malfunction is displayed as soon as “DATA MONITOR” is selected, reset CONSULT-II to “MANU
TRIG”. By selecting “MANU TRIG” you can monitor and store the data. The data can be utilized for further diagnosis, such as a comparison with the value for the normal operating condition.

Remarks:
● Specification data are reference values.
● Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in
spite of the ignition timing not being adjusted to the specification data. This IGN TIMING monitors the data calculated by the ECM
according to the signals input from the camshaft position sensor and other ignition timing related sensors.

Intermittent incidents may occur. In many cases, the malfunction resolves itself (the part or circuit function
returns to normal without intervention). It is important to realize that the symptoms described in the customer's EC
complaint often do not recur on (1st trip) DTC visits. Realize also that the most frequent cause of Intermittent
Incidents occurrences is poor electrical connections. Because of this, the conditions under which the incident
occurred may not be clear. Therefore, circuit checks made as part of the standard diagnostic procedure may

Ground Inspection
UBS00ELS
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground
connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can
become an unwanted resistance. This unwanted resistance can change the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even
when the ground connection looks clean, there can be a thin film of rust on the surface.
When inspecting a ground connection follow these rules:
●
Remove the ground bolt or screw.
●
Inspect all mating surfaces for tarnish, dirt, rust, etc.
●
Clean as required to assure good contact.
●
Reinstall bolt or screw securely.
●
Inspect for “add-on” accessories which may be interfering with the ground circuit.
●
If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the
wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.
For detailed ground distribution information, refer to PG-29, "Ground Distribution" .

*: This signal is sent to ECM through CAN communication line.
PBIB3085E
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid
valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to
increase engine torque in low/mid speed range and output in high-speed range.

DTC P0075 IVT CONTROL SOLENOID VALVE
Component Description
PFP:23796
A
UBS00NPW
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.

DTC P0101 MAF SENSOR
Component Description
PFP:22680
UBS002PU
The mass air flow sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake
flow. The mass air flow sensor controls the temperature of the hot
wire to a certain amount. The heat generated by the hot wire is
reduced as the intake air flows around it. The more air, the greater
the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.

Component Description
PFP:16119
UBS002ZQ
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometers which transform the throttle valve position into
output voltage, and emit the voltage signal to the ECM. In addition,
these sensors detect the opening and closing speed of the throttle
valve and feed the voltage signals to the ECM. The ECM judges the
current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve
opening angle properly in response to driving condition.

FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MIL lights up.
Engine operation condition in fail-safe mode
The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10
degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.

Component Description

A
UBS00NQ4
The A/F sensor 1 is a planar dual-cell limit current sensor. The sensor element of the A/F sensor 1 is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, which
transports ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range (0.7 <
< air).
The exhaust gas components diffuse through the diffusion gap at the
electrode of the oxygen pump and Nernst concentration cell, where
they are brought to thermodynamic balance.
EC

D
SEF579Z
E
An electronic circuit controls the pump current through the oxygenpump cell so that the composition of the exhaust gas in the diffusion
gap remains constant at = 1. Therefore, the A/F sensor 1 is able to
indicate air-fuel ratio by this pumping of current. In addition, a heater
is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).

DTC P0132 A/F SENSOR 1
Component Description
PFP:22693
UBS00NQJ
The A/F sensor 1 is a planar dual-cell limit current sensor. The sensor element of the A/F sensor 1 is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, which
transports ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range (0.7 <
< air).
The exhaust gas components diffuse through the diffusion gap at the
electrode of the oxygen pump and Nernst concentration cell, where
they are brought to thermodynamic balance.
SEF579Z
An electronic circuit controls the pump current through the oxygenpump cell so that the composition of the exhaust gas in the diffusion
gap remains constant at = 1. Therefore, the A/F sensor 1 is able to
indicate air-fuel ratio by this pumping of current. In addition, a heater
is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).

To judge the malfunction of air fuel ratio (A/F) sensor 1, this diagnosis measures response time of the A/F signal computed by ECM from the air fuel ratio (A/F) sensor 1 signal. The time is compensated by engine operating (speed and load), fuel feedback control constant, and the air fuel ratio (A/F) sensor 1 temperature index.

UBS00OZF
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the A/F sensor 1 are shifted, the
air-fuel ratio is controlled to stoichiometric, by the signal from the
heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions.
Under normal conditions the heated oxygen sensor 2 is not used for
engine control operation.

DTC P0138 HO2S2
Component Description
PFP:226A0
A
UBS00OZG
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the A/F sensor 1 are shifted, the
air-fuel ratio is controlled to stoichiometric, by the signal from the
heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions.
Under normal conditions the heated oxygen sensor 2 is not used for
engine control operation.

Component Description
PFP:226A0
A
UBS002S5
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the A/F sensor 1 are shifted, the
air-fuel ratio is controlled to stoichiometric, by the signal from the
heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions.
Under normal conditions the heated oxygen sensor 2 is not used for
engine control operation.

On Board Diagnosis Logic
UBS002S7
The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the A/F sensor 1. The oxygen storage
capacity before the three way catalyst (manifold) causes the longer
switching time. To judge the malfunctions of heated oxygen sensor
2, ECM monitors whether the switching response of the sensor's
voltage is faster than specified during the various driving condition
such as fuel-cut.

With the Air-Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the
theoretical mixture ratio based on the mixture ratio feedback signal from the A/F sensor 1. The ECM calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the
ECM judges the condition as the fuel injection system malfunction and lights up the MIL (2 trip detection logic).

UBS002SI
With the Air-Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the
theoretical mixture ratio based on the mixture ratio feedback signal from the A/F sensor 1. The ECM calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The actual mixture ratio is too rich.), the
ECM judges the condition as the fuel injection system malfunction and lights up the MIL (2 trip detection logic).

DTC P0222, P0223 TP SENSOR
Component Description
PFP:16119
UBS002TF
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometers which transform the throttle valve position into
output voltage, and emit the voltage signal to the ECM. In addition,
these sensors detect the opening and closing speed of the throttle
valve and feed the voltage signals to the ECM. The ECM judges the
current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve
opening angle properly in response to driving condition.

FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MIL lights up.
Engine operation condition in fail-safe mode
The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10
degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.

On Board Diagnosis Logic
A
UBS002U3
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crank- EC
shaft position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is occurring.

On board diagnosis of misfire
The misfire detection logic consists of the following two conditions.
1. One Trip Detection Logic (Three Way Catalyst Damage)
On the 1st trip that a misfire condition occurs that can damage the three way catalyst (TWC) due to overheating, the MIL will blink.
When a misfire condition occurs, the ECM monitors the CKP sensor (POS) signal every 200 engine revolutions for a change.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will turn off.
If another misfire condition occurs that can damage the TWC on a 2nd trip, the MIL will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will remain on.
If another misfire condition occurs that can damage the TWC, the MIL will begin to blink again.
2. Two Trip Detection Logic (Exhaust quality deterioration)
For misfire conditions that will not damage the TWC (but will affect vehicle emissions), the MIL will only
light when the misfire is detected on a 2nd trip. During this condition, the ECM monitors the CKP sensor
signal every 1,000 engine revolutions.
A misfire malfunction can be detected on any one cylinder or on multiple cylinders.
DTC No.

A
UBS002UD
The crankshaft position sensor (POS) is located on the cylinder
block rear housing facing the gear teeth (cogs) of the signal plate at
the end of the crankshaft. It detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
ECM receives the signals as shown in the figure.

DTC P0340 CMP SENSOR (PHASE)
Component Description
PFP:23731
UBS002UL
The camshaft position sensor (PHASE) senses the retraction with
camshaft (intake) to identify a particular cylinder. The camshaft position sensor (PHASE) senses the piston position.
When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor (PHASE) provides various controls of engine parts instead, utilizing timing of cylinder identification
signals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor changes.
ECM receives the signals as shown in the figure.

If DTC P0441 is displayed with other DTC such as P2122, P2123 P2127, P2128, P2138, first perform
trouble diagnosis for other DTC.
PBIB1026E
In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions.
Purge volume is related to air intake volume. Under normal purge conditions (non-closed throttle), the EVAP
canister purge volume control solenoid valve is open to admit purge flow. Purge flow exposes the EVAP control system pressure sensor to intake manifold vacuum.
On Board Diagnosis Logic

control solenoid valve
*1: ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to the ECM though CAN communication line.
This system controls flow rate of fuel vapor from the EVAP canister. The opening of the vapor by-pass passage in the EVAP canister purge volume control solenoid valve changes to control the flow rate. The EVAP
canister purge volume control solenoid valve repeats ON/OFF operation according to the signal sent from the
ECM. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is
determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapor
from the EVAP canister is regulated as the air flow changes.
COMPONENT DESCRIPTION
The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount of fuel vapor that will flow through the valve.

This system controls flow rate of fuel vapor from the EVAP canister. The opening of the vapor by-pass passage in the EVAP canister purge volume control solenoid valve changes to control the flow rate. The EVAP
canister purge volume control solenoid valve repeats ON/OFF operation according to the signal sent from the
ECM. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is
determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapor
from the EVAP canister is regulated as the air flow changes.
H
I
COMPONENT DESCRIPTION
The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount of fuel vapor that will flow through the valve.

Component Description

A
UBS00CDH
The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.
This solenoid valve responds to signals from the ECM. When the
ECM sends an ON signal, the coil in the solenoid valve is energized.
A plunger will then move to seal the canister vent. The ability to seal
the vent is necessary for the on board diagnosis of other evaporative
emission control system components.
This solenoid valve is used only for diagnosis, and usually remains
opened.
When the vent is closed, under normal purge conditions, the evaporative emission control system is depressurized and allows EVAP
Control System diagnoses.

sensor detects a fuel level in the fuel tank and transmits a signal to
the combination meter. The combination meter sends the fuel level
sensor signal to the ECM through CAN communication line.
It consists of two parts, one is mechanical float and the other is variable resistor. Fuel level sensor output voltage changes depending on
the movement of the fuel mechanical float.

NOTE:
If DTC P0506 is displayed with other DTC, first perform the trouble diagnosis for the other DTC.
The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idling speed. The crankshaft position sensor (POS) detects
the actual engine speed and sends a signal to the ECM.
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value
memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.
The optimum value stored in the ECM is determined by taking into consideration various engine conditions,
such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan
operation, etc.).

UBS002ZY
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometers which transform the throttle valve position into
output voltage, and emit the voltage signal to the ECM. In addition,
these sensors detect the opening and closing speed of the throttle
valve and feed the voltage signals to the ECM. The ECM judges the
current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve
opening angle properly in response to driving condition.

DTC P1800 VIAS CONTROL SOLENOID VALVE
Component Description
PFP:14955
UBS00C7P
The VIAS control solenoid valve cuts the intake manifold vacuum
signal for power valve control. It responds to ON/OFF signals from
the ECM. When the solenoid is OFF, the vacuum signal from the
intake manifold is cut. When the ECM sends an ON signal the coil
pulls the plunger downward and feeds the vacuum signal to the
power valve actuator.

The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10
degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.

Component Description
PFP:16119
UBS002T7
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometers which transform the throttle valve position into
output voltage, and emit the voltage signal to the ECM. In addition,
these sensors detect the opening and closing speed of the throttle
valve and feed the voltage signals to the ECM. The ECM judges the
current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve
opening angle properly in response to driving condition.

DTC P2A00 A/F SENSOR 1
Component Description
PFP:22693
A
UBS00NSZ
The A/F sensor 1 is a planar dual-cell limit current sensor. The sensor element of the A/F sensor 1 is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, which
transports ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range (0.7 <
< air).
The exhaust gas components diffuse through the diffusion gap at the
electrode of the oxygen pump and Nernst concentration cell, where
they are brought to thermodynamic balance.
EC
C
D
SEF579Z
E
An electronic circuit controls the pump current through the oxygenpump cell so that the composition of the exhaust gas in the diffusion
gap remains constant at = 1. Therefore, the A/F sensor 1 is able to
indicate air-fuel ratio by this pumping of current. In addition, a heater
is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).

FUEL INJECTOR
[QR]
FUEL INJECTOR
Component Description
PFP:16600
UBS00NTC
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the needle valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for 1 second after the ignition switch is turned ON to improve engine startability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows that
the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the
ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging,
thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump
relay, which in turn controls the fuel pump.

When the engine is running at low or medium speed, the power valve is fully closed. Under this condition, the
effective suction port length is equivalent to the total length of the intake manifold collector's suction port
including the intake valve. This long suction port provides increased air intake which results in improved suction efficiency and higher torque generation.
The surge tank and one-way valve are provided. When engine is running at high speed, the ECM sends the
signal to the VIAS control solenoid valve. This signal introduces the intake manifold vacuum into the power
valve actuator and therefore opens the power valve to two suction passages together in the collector.
Under this condition, the effective port length is equivalent to the length of the suction port provided independently for each cylinder. This shortened port length results in enhanced engine output with reduced suction
resistance under high speeds.

COMPONENT DESCRIPTION
Power Valve
The power valve is installed in intake manifold collector and used to
control the suction passage of the variable induction air control system. It is set in the fully closed or fully opened position by the power
valve actuator operated by the vacuum stored in the surge tank. The
vacuum in the surge tank is controlled by the VIAS control solenoid
valve.
BBIA0022E
VIAS Control Solenoid Valve
The VIAS control solenoid valve cuts the intake manifold vacuum
signal for power valve control. It responds to ON/OFF signals from
the ECM. When the solenoid is off, the vacuum signal from the
intake manifold is cut. When the ECM sends an ON signal the coil
pulls the plunger downward and feeds the vacuum signal to the
power valve actuator.

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
UBS00IIZ
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
On Board Diagnostic (OBD) System of Engine and A/T
UBS00HZI
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
●
Be sure to turn the ignition switch OFF and disconnect the negative battery cable before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MIL to light up.
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
●
Certain systems and components, especially those related to OBD, may use a new style slidelocking type harness connector. For description and how to disconnect, refer to PG-66, "HARNESS CONNECTOR" .
●
Be sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MIL to light up due to the short circuit.
●
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to the malfunction of the EVAP system or fuel injection system,
etc.
●
Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.
Precaution
●
●
●
●
UBS00HZJ
Always use a 12 volt battery as power source.
Do not attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness connector, turn ignition switch OFF and disconnect negative
battery cable. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned OFF.
Before removing parts, turn ignition switch OFF and then
disconnect negative battery cable.

time the valve remains open (injection pulse duration). The amount of fuel injected is a program value in the
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from both the crankshaft position sensor and the mass air
flow sensor.

MIXTURE RATIO FEEDBACK CONTROL (CLOSED LOOP CONTROL)
A
EC
C
PBIB3020E
The mixture ratio feedback system provides the best air-fuel mixture ratio for driveability and emission control.
The three way catalyst (manifold) can then better reduce CO, HC and NOx emissions. This system uses air
fuel ratio (A/F) sensor 1 in the exhaust manifold to monitor whether the engine operation is rich or lean. The
ECM adjusts the injection pulse width according to the sensor voltage signal. For more information about air
fuel ratio (A/F) sensor 1, refer to EC-846, "DTC P0131, P0151 A/F SENSOR 1" . This maintains the mixture
ratio within the range of stoichiometric (ideal air-fuel mixture).
This stage is referred to as the closed loop control condition.
Heated oxygen sensor 2 is located downstream of the three way catalyst (manifold). Even if the switching
characteristics of air fuel ratio (A/F) sensor 1 shift, the air-fuel ratio is controlled to stoichiometric by the signal
from heated oxygen sensor 2.

MIXTURE RATIO SELF-LEARNING CONTROL
The mixture ratio feedback control system monitors the mixture ratio signal transmitted from A/F sensor 1.
This feedback signal is then sent to the ECM. The ECM controls the basic mixture ratio as close to the theoretical mixture ratio as possible. However, the basic mixture ratio is not necessarily controlled as originally
designed. Both manufacturing differences (i.e., mass air flow sensor hot wire) and characteristic changes during operation (i.e., fuel injector clogging) directly affect mixture ratio.
Accordingly, the difference between the basic and theoretical mixture ratios is monitored in this system. This is
then computed in terms of “injection pulse duration” to automatically compensate for the difference between
the two ratios.
“Fuel trim” refers to the feedback compensation value compared against the basic injection duration. Fuel trim
includes short term fuel trim and long term fuel trim.
“Short term fuel trim” is the short-term fuel compensation used to maintain the mixture ratio at its theoretical
value. The signal from A/F sensor 1 indicates whether the mixture ratio is RICH or LEAN compared to the theoretical value. The signal then triggers a reduction in fuel volume if the mixture ratio is rich, and an increase in
fuel volume if it is lean.
“Long term fuel trim” is overall fuel compensation carried out long-term to compensate for continual deviation
of the short term fuel trim from the central value. Such deviation will occur due to individual engine differences,
wear over time and changes in the usage environment.

FUEL INJECTION TIMING
SEF179U
Two types of systems are used.
Sequential Multiport Fuel Injection System
Fuel is injected into each cylinder during each engine cycle according to the firing order. This system is used
when the engine is running.
Simultaneous Multiport Fuel Injection System
Fuel is injected simultaneously into all six cylinders twice each engine cycle. In other words, pulse signals of
the same width are simultaneously transmitted from the ECM.
The six fuel injectors will then receive the signals two times for each engine cycle.
This system is used when the engine is being started and/or if the fail-safe system (CPU) is operating.
FUEL SHUT-OFF
Fuel to each cylinder is cut off during deceleration, operation of the engine at excessively high speeds or operation of the vehicle at excessively high speeds.

Description

SYSTEM DESCRIPTION
PBIB1631E
The evaporative emission system is used to reduce hydrocarbons emitted into the atmosphere from the fuel
system. This reduction of hydrocarbons is accomplished by activated charcoals in the EVAP canister.
The fuel vapor in the sealed fuel tank is led into the EVAP canister which contains activated carbon and the
vapor is stored there when the engine is not operating or when refueling to the fuel tank.
The vapor in the EVAP canister is purged by the air through the purge line to the intake manifold when the
engine is operating. EVAP canister purge volume control solenoid valve is controlled by ECM. When the
engine operates, the flow rate of vapor controlled by EVAP canister purge volume control solenoid valve is
proportionally regulated as the air flow increases.
EVAP canister purge volume control solenoid valve also shuts off the vapor purge line during decelerating and
idling.

PBIB1387E
From the beginning of refueling, the air and vapor inside the fuel tank go through refueling EVAP vapor cut
valve and EVAP/ORVR line to the EVAP canister. The vapor is absorbed by the EVAP canister and the air is
released to the atmosphere.
When the refueling has reached the full level of the fuel tank, the refueling EVAP vapor cut valve is closed and
refueling is stopped because of auto shut-off. The vapor which was absorbed by the EVAP canister is purged
during driving.
WARNING:
When conducting inspections below, be sure to observe the following:
●
Put a “CAUTION: INFLAMMABLE” sign in workshop.
●
Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
●
Be sure to furnish the workshop with a CO2 fire extinguisher.
CAUTION:
●
Before removing fuel line parts, carry out the following procedures:
–
Put drained fuel in an explosion-proof container and put lid on securely.
–
Release fuel pressure from fuel line. Refer to EC-686, "FUEL PRESSURE RELEASE" .
–
Disconnect battery ground cable.
●
Always replace O-ring when the fuel gauge retainer is removed.
●
Do not kink or twist hose and tube when they are installed.
●
Do not tighten hose and clamps excessively to avoid damaging hoses.
●
After installation, run engine and check for fuel leaks at connection.
●
Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.

POSITIVE CRANKCASE VENTILATION
Description
PFP:11810
UBS00IG2
SYSTEM DESCRIPTION
SEC921C
This system returns blow-by gas to the intake manifold.
The positive crankcase ventilation (PCV) valve is provided to conduct crankcase blow-by gas to the intake
manifold. During partial throttle operation of the engine, the intake manifold sucks the blow-by gas through the
PCV valve. Normally, the capacity of the valve is sufficient to handle any blow-by and a small amount of ventilating air. The ventilating air is then drawn from the air inlet tubes into the crankcase. In this process the air
passes through the hose connecting air inlet tubes to rocker cover. Under full-throttle condition, the manifold
vacuum is insufficient to draw the blow-by flow through the valve. The flow goes through the hose connection
in the reverse direction.
On vehicles with an excessively high blow-by, the valve does not
meet the requirement. This is because some of the flow will go
through the hose connection to the air inlet tubes under all conditions.
PBIB1588E
Component Inspection

PCV (POSITIVE CRANKCASE VENTILATION) VALVE
With engine running at idle, remove PCV valve from rocker cover. A
properly working valve makes a hissing noise as air passes through
it. A strong vacuum should be felt immediately when a finger is
placed over valve inlet.

The malfunction indicator lamp (MIL) on the instrument panel lights up when the same malfunction is detected
in two consecutive trips (Two trip detection logic), or when the ECM enters fail-safe mode. (Refer to EC-697 .)
I
UBS00I03
When a malfunction is detected for the first time, 1st trip DTC and 1st trip Freeze Frame data are stored in the
ECM memory. The MIL will not light up at this stage. <1st trip>
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in
the ECM memory, and the MIL lights up. The MIL lights up at the same time when the DTC is stored. <2nd
trip> The “trip” in the “Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation. Specific on board diagnostic items will cause the ECM to light up or blink the MIL,
and store DTC and Freeze Frame data, even in the 1st trip, as shown below.

When there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when there is
malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as
NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by means
of operating fail-safe function.

*4: SRT code will not be set if the self-diagnostic result is NG.
*5: The troubleshooting for this DTC need CONSULT-II.

*7: When the ECM is in the mode of displaying SRT status, MIL may flash. For the details, refer to EC-662, "How to Display SRT Status"
.
DTC AND 1ST TRIP DTC
The 1st trip DTC (whose number is the same as the DTC number) is displayed for the latest self-diagnostic
result obtained. If the ECM memory was cleared previously, and the 1st trip DTC did not reoccur, the 1st trip
DTC will not be displayed.
If a malfunction is detected during the 1st trip, the 1st trip DTC is stored in the ECM memory. The MIL will not
light up (two trip detection logic). If the same malfunction is not detected in the 2nd trip (meeting the required
driving pattern), the 1st trip DTC is cleared from the ECM memory. If the same malfunction is detected in the
2nd trip, both the 1st trip DTC and DTC are stored in the ECM memory and the MIL lights up. In other words,
the DTC is stored in the ECM memory and the MIL lights up when the same malfunction occurs in two consecutive trips. If a 1st trip DTC is stored and a non-diagnostic operation is performed between the 1st and 2nd
trips, only the 1st trip DTC will continue to be stored. For malfunctions that blink or light up the MIL during the
1st trip, the DTC and 1st trip DTC are stored in the ECM memory.
Procedures for clearing the DTC and the 1st trip DTC from the ECM memory are described in EC-666, "HOW
TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .

ON BOARD DIAGNOSTIC (OBD) SYSTEM
[VQ]
For malfunctions in which 1st trip DTCs are displayed, refer to EC-654, "EMISSION-RELATED DIAGNOSTIC
INFORMATION ITEMS" . These items are required by legal regulations to continuously monitor the system/
component. In addition, the items monitored non-continuously are also displayed on CONSULT-II.
1st trip DTC is specified in Service $07 of SAE J1979. 1st trip DTC detection occurs without lighting up the MIL
and therefore does not warn the driver of a malfunction. However, 1st trip DTC detection will not prevent the
vehicle from being tested, for example during Inspection/Maintenance (I/M) tests.
When a 1st trip DTC is detected, check, print out or write down and erase (1st trip) DTC and Freeze Frame
data as specified in Work Flow procedure Step 2, refer to EC-690, "WORK FLOW" . Then perform DTC Confirmation Procedure or Overall Function Check to try to duplicate the malfunction. If the malfunction is duplicated, the item requires repair.
How to Read DTC and 1st Trip DTC
DTC and 1st trip DTC can be read by the following methods.
With CONSULT-II
With GST
CONSULT-II or GST (Generic Scan Tool) Examples: P0340, P1148, P2101, etc.
These DTCs are prescribed by SAE J2012.
(CONSULT-II also displays the malfunctioning component or system.)
No Tools
The number of blinks of the MIL in the Diagnostic Test Mode II (Self-Diagnostic Results) indicates the DTC.
Example: 0340, 1148, 2101, etc.
These DTCs are controlled by NISSAN.
●
1st trip DTC No. is the same as DTC No.
●
Output of a DTC indicates a malfunction. However, GST or the Diagnostic Test Mode II do not indicate whether the malfunction is still occurring or has occurred in the past and has returned to normal. CONSULT-II can identify malfunction status as shown below. Therefore, using CONSULT-II (if
available) is recommended.
A sample of CONSULT-II display for DTC and 1st trip DTC is shown below. DTC or 1st trip DTC of a malfunction is displayed in SELF-DIAGNOSTIC RESULTS mode of CONSULT-II. Time data indicates how many times
the vehicle was driven after the last detection of a DTC.
If the DTC is being detected currently, the time data will be [0].
If a 1st trip DTC is stored in the ECM, the time data will be [1t].

FREEZE FRAME DATA AND 1ST TRIP FREEZE FRAME DATA
The ECM records the driving conditions such as fuel system status, calculated load value, engine coolant tem- A
perature, short term fuel trim, long term fuel trim, engine speed, vehicle speed, absolute throttle position, base
fuel schedule and intake air temperature at the moment a malfunction is detected.
Data which are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data. EC
The data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II or
GST. The 1st trip freeze frame data can only be displayed on the CONSULT-II screen, not on the GST. For
details, see EC-726, "Freeze Frame Data and 1st Trip Freeze Frame Data" .
Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in the C
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no D
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the following priorities to update the data.
Priority

Items
Freeze frame data

Fuel Injection System Function — DTC: P0171, P0172, P0174, P0175
F
Except the above items (Includes A/T related items)
1st trip freeze frame data
For example, the EGR malfunction (Priority: 2) was detected and the freeze frame data was stored in the 2nd
trip. After that when the misfire (Priority: 1) is detected in another trip, the freeze frame data will be updated
from the EGR malfunction to the misfire. The 1st trip freeze frame data is updated each time a different malfunction is detected. There is no priority for 1st trip freeze frame data. However, once freeze frame data is
stored in the ECM memory, 1st trip freeze data is no longer stored (because only one freeze frame data or 1st
trip freeze frame data can be stored in the ECM). If freeze frame data is stored in the ECM memory and freeze
frame data with the same priority occurs later, the first (original) freeze frame data remains unchanged in the
ECM memory.
Both 1st trip freeze frame data and freeze frame data (along with the DTCs) are cleared when the ECM memory is erased. Procedures for clearing the ECM memory are described in EC-666, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
SYSTEM READINESS TEST (SRT) CODE
System Readiness Test (SRT) code is specified in Service $01 of SAE J1979.
As part of an enhanced emissions test for Inspection & Maintenance (I/M), certain states require the status of
SRT be used to indicate whether the ECM has completed self-diagnosis of major emission systems and components. Completion must be verified in order for the emissions inspection to proceed.
If a vehicle is rejected for a State emissions inspection due to one or more SRT items indicating “INCMP”, use
the information in this Service Manual to set the SRT to “CMPLT”.
In most cases the ECM will automatically complete its self-diagnosis cycle during normal usage, and the SRT
status will indicate “CMPLT” for each application system. Once set as “CMPLT”, the SRT status remains
“CMPLT” until the self-diagnosis memory is erased.
Occasionally, certain portions of the self-diagnostic test may not be completed as a result of the customer's
normal driving pattern; the SRT will indicate “INCMP” for these items.
NOTE:
The SRT will also indicate “INCMP” if the self-diagnosis memory is erased for any reason or if the ECM memory power supply is interrupted for several hours.
If, during the state emissions inspection, the SRT indicates “CMPLT” for all test items, the inspector will continue with the emissions test. However, if the SRT indicates “INCMP” for one or more of the SRT items the
vehicle is returned to the customer untested.
NOTE:
If MIL is ON during the state emissions inspection, the vehicle is also returned to the customer untested even
though the SRT indicates “CMPLT” for all test items. Therefore, it is important to check SRT (“CMPLT”) and
DTC (No DTCs) before the inspection.

When all SRT related self-diagnoses showed OK results through several different cycles, the SRT will indicate
“CMPLT” at the time the respective self-diagnoses have at least one OK result. → Case 2 above
If one or more SRT related self-diagnoses showed NG results in 2 consecutive cycles, the SRT will also indicate “CMPLT”. → Case 3 above
The table above shows that the minimum number of cycles for setting SRT as “INCMP” is one (1) for each
self-diagnosis (Case 1 & 2) or two (2) for one of self-diagnoses (Case 3). However, in preparation for the state

[VQ]
emissions inspection, it is unnecessary for each self-diagnosis to be executed twice (Case 3) for the following
reasons:
A
●
The SRT will indicate “CMPLT” at the time the respective self-diagnoses have one (1) OK result.
●
The emissions inspection requires “CMPLT” of the SRT only with OK self-diagnosis results.
●
When, during SRT driving pattern, 1st trip DTC (NG) is detected prior to “CMPLT” of SRT, the self-diagno- EC
sis memory must be erased from ECM after repair.
●
If the 1st trip DTC is erased, all the SRT will indicate “INCMP”.
C
NOTE:
SRT can be set as “CMPLT” together with the DTC(s). Therefore, DTC check must always be carried out
prior to the state emission inspection even though the SRT indicates “CMPLT”.
D

How to Display SRT Status
WITH CONSULT-II
Selecting “SRT STATUS” in “DTC CONFIRMATION” mode with
CONSULT-II.
For items whose SRT codes are set, a “CMPLT” is displayed on the
CONSULT-II screen; for items whose SRT codes are not set,
“INCMP” is displayed.
A sample of CONSULT-II display for SRT code is shown in the figure.
“INCMP” means the self-diagnosis is incomplete and SRT is not set.
“CMPLT” means the self-diagnosis is complete and SRT is set.
NOTE:
Though displayed on the CONSULT-II screen, “HO2S HTR” is not
SRT item.
WITH GST
Selecting Service $01 with GST (Generic Scan Tool)
NO TOOLS
A SRT code itself can not be displayed while only SRT status can be.
1. Turn ignition switch ON and wait 20 seconds.
2. SRT status is indicated as shown below.
● When all SRT codes are set, MIL lights up continuously.
● When any SRT codes are not set, MIL will flash periodically for 10 seconds.

How to Set SRT Code
To set all SRT codes, self-diagnosis for the items indicated above must be performed one or more times. Each
diagnosis may require a long period of actual driving under various conditions.
WITH CONSULT-II
Perform corresponding DTC Confirmation Procedure one by one based on Performance Priority in the table
on EC-660, "SRT Item" .
WITHOUT CONSULT-II
The most efficient driving pattern in which SRT codes can be properly set is explained on the next page. The
driving pattern should be performed one or more times to set all SRT codes.

The time required for each diagnosis varies with road surface conditions, weather, altitude, individual driving habits, etc.
Zone A refers to the range where the time, required for the diagnosis under normal conditions*, is the
shortest.
Zone B refers to the range where the diagnosis can still be performed if the diagnosis is not completed
within zone A.
*: Normal conditions refer to the following:
●
Sea level
●
Flat road
●
Ambient air temperature: 20 - 30°C (68 - 86°F)
●
Diagnosis is performed as quickly as possible under normal conditions.
Under different conditions [For example: ambient air temperature other than 20 - 30°C (68 - 86°F)], diagnosis may also be performed.
Pattern 1:
●
The engine is started at the engine coolant temperature of −10 to 35°C (14 to 95°F)
(where the voltage between the ECM terminal 73 and ground is 3.0 - 4.3V).
●
The engine must be operated at idle speed until the engine coolant temperature is greater than
70°C (158°F) (where the voltage between the ECM terminal 73 and ground is lower than 1.4V).
●
The engine is started at the fuel tank temperature of warmer than 0°C (32°F) (where the voltage
between the ECM terminal 107 and ground is less than 4.1V).
Pattern 2:
●
When steady-state driving is performed again even after it is interrupted, each diagnosis can be conducted. In this case, the time required for diagnosis may be extended.
Pattern 3:
●
The driving pattern outlined in *2 must be repeated at least 3 times.
Pattern 4:
●
Tests are performed after the engine has been operated for at least 17 minutes.
●
The accelerator pedal must be held very steady during steady-state driving.
●
If the accelerator pedal is moved, the test must be conducted all over again.
*1: Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH), then release the accelerator pedal
and keep it released for more than 10 seconds. Depress the accelerator pedal until vehicle speed is 90 km/h
(56 MPH) again.
*2: Operate the vehicle in the following driving pattern.
1. Decelerate vehicle to 0 km/h (0 MPH) and let engine idle.
2. Repeat driving pattern shown at right at least 10 times.
–
During acceleration, hold the accelerator pedal as steady as
possible.
*3: Checking the vehicle speed with GST is advised.

DESCRIPTION
The MIL is located on the instrument panel.
1. The MIL will light up when the ignition switch is turned ON without the engine running. This is a bulb check.
If the MIL does not light up, refer to DI-31, "WARNING LAMPS" ,
or see EC-1302 .
2. When the engine is started, the MIL should go off.
If the MIL remains on, the on board diagnostic system has
detected an engine system malfunction.

M
When there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when there is
malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as
NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by means
of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MIL circuit are detected and demands the
driver to repair the malfunction.
Engine operating condition in fail-safe mode
Engine speed will not rise more than 2,500 rpm due to the fuel cut
MIL Flashing Without DTC
When any SRT codes are not set, MIL may flash without DTC. For the details, refer to EC-662, "How to Display SRT Status" .

A particular trouble code can be identified by the number of four-digit numeral flashes. The “zero” is indicated
by the number of ten flashes. The “A” is indicated by the number of eleven flash. The length of time the
1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-second) - OFF (0.6-second)
cycle.
The 100th-digit numeral and lower digit numerals consist of a 0.3-second ON and 0.3-second OFF cycle.
A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-second OFF.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC 0000 refers to no malfunction. (See EC-614, "INDEX FOR DTC" )
How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
The DTC can be erased from the back up memory in the ECM by depressing accelerator pedal. Refer to EC670, "How to Erase Diagnostic Test Mode II (Self-diagnostic Results)" .

The MIL will go off after the vehicle is driven 3 times (driving pattern B) with no malfunction. The drive is
counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction
occurs while counting, the counter will reset.
The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A)
without the same malfunction recurring (except for Misfire and Fuel Injection System). For Misfire and
Fuel Injection System, the DTC and freeze frame data will be stored until the vehicle is driven 80 times
(driving pattern C) without the same malfunction recurring. The “TIME” in “SELF-DIAGNOSTIC
RESULTS” mode of CONSULT-II will count the number of times the vehicle is driven.
The 1st trip DTC is not displayed when the self-diagnosis results in OK for the 2nd trip.

EXPLANATION FOR DRIVING PATTERNS FOR “MISFIRE ”, “FUEL INJECTION SYSTEM”
Driving pattern B means the vehicle operation as follows:
All components and systems should be monitored at least once by the OBD system.
●
The B counter will be cleared when the malfunction is detected once regardless of the driving pattern.
●
The B counter will be counted up when driving pattern B is satisfied without any malfunction.
●
The MIL will go off when the B counter reaches 3. (*2 in “OBD SYSTEM OPERATION CHART”)
Driving pattern C means the vehicle operation as follows:
The following conditions should be satisfied at the same time:
Engine speed: (Engine speed in the freeze frame data) ±375 rpm
Calculated load value: (Calculated load value in the freeze frame data) x (1±0.1) [%]
Engine coolant temperature (T) condition:
●
When the freeze frame data shows lower than 70°C (158°F), T should be lower than 70°C (158°F).
●
When the freeze frame data shows higher than or equal to 70°C (158°F), T should be higher than or equal
to 70°C (158°F).
Example:
If the stored freeze frame data is as follows:
Engine speed: 850 rpm, Calculated load value: 30%, Engine coolant temperature: 80°C (176°F)
To be satisfied with driving pattern C, the vehicle should run under the following conditions:
Engine speed: 475 - 1,225 rpm, Calculated load value: 27 - 33%, Engine coolant temperature: more than 70°C
(158°F)
●
The C counter will be cleared when the malfunction is detected regardless of vehicle conditions above.
●
The C counter will be counted up when vehicle conditions above is satisfied without the same malfunction.
●
The DTC will not be displayed after C counter reaches 80.
●
The 1st trip DTC will be cleared when C counter is counted once without the same malfunction after DTC
is stored in ECM.

UBS00I08
INTRODUCTION
The engine has an ECM to control major systems such as fuel control, ignition control, idle air control system, etc. The ECM accepts
input signals from sensors and instantly drives actuators. It is essential that both input and output signals are proper and stable. At the
same time, it is important that there are no malfunctions such as vacuum leaks, fouled spark plugs, or other malfunctions with the engine.

It is much more difficult to diagnose an incident that occurs intermittently rather than continuously. Most intermittent incidents are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replacement of good parts.

H
SEF233G
I
A visual check only may not find the cause of the incidents. A road
test with CONSULT-II (or GST) or a circuit tester connected should
be performed. Follow the WORK FLOW on EC-690 .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The customer can supply good information about such incidents, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A DIAGNOSTIC WORKSHEET like the
example on EC-694 should be used.
Start your diagnosis by looking for conventional malfunctions first.
This will help troubleshoot driveability malfunctions on an electronically controlled engine vehicle.

DIAGNOSTIC WORKSHEET
Description
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a incident. It is
important to fully understand the symptoms or conditions for a customer complaint.
Utilize a diagnostic worksheet like the one on the next page in order
to organize all the information for troubleshooting.
Some conditions may cause the MIL to come on steady or blink and
DTC to be detected. Examples:
●
Vehicle ran out of fuel, which caused the engine to misfire.
●
Fuel filler cap was left off or incorrectly screwed on, allowing fuel
to evaporate into the atmosphere.

Fail-safe Chart
UBS00I0A
A
When the DTC listed below is detected, the ECM enters fail-safe mode and the MIL lights up.
DTC No.
Detected items
Engine operating condition in fail-safe mode
P0102
P0103
Mass air flow sensor circuit
Engine speed will not rise more than 2,400 rpm due to the fuel cut.
P0117
P0118
Engine coolant temperature sensor circuit
Engine coolant temperature will be determined by ECM based on the time after turning
ignition switch ON or START.
CONSULT-II displays the engine coolant temperature decided by ECM.
Condition
Engine coolant temperature decided
(CONSULT-II display)
Just as ignition switch is turned

Except as shown above
EC
D
E
40 - 80°C (104 - 176°F)
(Depends on the time)
When the fail-safe system for engine coolant temperature sensor is activated, the cooling
fan operates while engine is running.
F
P0122
P0123
P0222
P0223
P2135
Throttle position sensor
The ECM controls the electric throttle control actuator in regulating the throttle opening in
order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal
condition.
So, the acceleration will be poor.
P0643
Sensor power supply
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2100
P2103
Throttle control motor relay
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2101
Electric throttle control
function
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2118
Throttle control motor
ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2119
Electric throttle control
actuator
(When electric throttle control actuator does not function properly due to the return spring
malfunction:)
ECM controls the electric throttle actuator by regulating the throttle opening around the
idle position. The engine speed will not rise more than 2,000 rpm.
K
(When ECM detects the throttle valve is stuck open:)
While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops,
the engine stalls.
The engine can restart in N or P position, and engine speed will not exceed 1,000 rpm or
more.
L
(When throttle valve opening angle in fail-safe mode is not in specified range:)
ECM controls the electric throttle control actuator by regulating the throttle opening to 20
degrees or less.
P2122
P2123
P2127
P2128
P2138
●
C
Accelerator pedal position
sensor
The ECM controls the electric throttle control actuator in regulating the throttle opening in
order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal
condition.
So, the acceleration will be poor.
When there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when
there is malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected
as NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by
means of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MIL circuit are detected and demands
the driver to repair the malfunction.

REAL TIME DIAGNOSIS IN DATA MONITOR MODE (RECORDING VEHICLE DATA)
Description
CONSULT-II has two kinds of triggers and they can be selected by touching “SETTING” in “DATA MONITOR”
mode.
1. “AUTO TRIG” (Automatic trigger):
● The malfunction will be identified on the CONSULT-II screen
in real time.
In other words, DTC/1st trip DTC and malfunction item will be
displayed if the malfunction is detected by ECM.
At the moment a malfunction is detected by ECM, “MONITOR” in “DATA MONITOR” screen is changed to “Recording
Data ... xx%” as shown at right, and the data after the malfunction detection is recorded. Then when the percentage
reached 100%, “REAL-TIME DIAG” screen is displayed. If
“STOP” is touched on the screen during “Recording Data ...
SEF705Y
xx%”, “REAL-TIME DIAG” screen is also displayed.
The recording time after the malfunction detection and the
recording speed can be changed by “TRIGGER POINT” and
“Recording Speed”. Refer to CONSULT-II Operation Manual.
2. “MANU TRIG” (Manual trigger):
● DTC/1st trip DTC and malfunction item will not be displayed
automatically on CONSULT-II screen even though a malfunction is detected by ECM.
DATA MONITOR can be performed continuously even though
a malfunction is detected.

“AUTO TRIG”
● While trying to detect the DTC/1st trip DTC by performing the DTC Confirmation Procedure, be sure to
select to “DATA MONITOR (AUTO TRIG)” mode. You can confirm the malfunction at the moment it is
detected.
EC
● While narrowing down the possible causes, CONSULT-II should be set in “DATA MONITOR (AUTO
TRIG)” mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, compo- C
nents and harness in the DTC Confirmation Procedure, the moment a malfunction is found the DTC/1st
trip DTC will be displayed. (Refer to “INCIDENT SIMULATION TESTS” in GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" .)
D
“MANU TRIG”
● If the malfunction is displayed as soon as “DATA MONITOR” is selected, reset CONSULT-II to “MANU
TRIG”. By selecting “MANU TRIG” you can monitor and store the data. The data can be utilized for furE
ther diagnosis, such as a comparison with the value for the normal operating condition.

Remarks:
● Specification data are reference values.
● Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in
spite of the ignition timing not being adjusted to the specification data. This IGN TIMING monitors the data calculated by the ECM
according to the signals input from the camshaft position sensor and other ignition timing related sensors.

Description
PFP:00031
UBS00I0L
The specification (SP) value indicates the tolerance of the value that is displayed in “DATA MONITOR (SPEC)”
mode of CONSULT-II during normal operation of the Engine Control System. When the value in “DATA MONITOR (SPEC)” mode is within the SP value, the Engine Control System is confirmed OK. When the value in
“DATA MONITOR (SPEC)” mode is NOT within the SP value, the Engine Control System may have one or
more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MIL.
The SP value will be displayed for the following three items:
●
B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correction)
●
A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)
●
MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
Description
PFP:00006
UBS00I0P
Intermittent incidents may occur. In many cases, the malfunction resolves itself (the part or circuit function
returns to normal without intervention). It is important to realize that the symptoms described in the customer's
complaint often do not recur on (1st trip) DTC visits. Realize also that the most frequent cause of intermittent
incidents occurrences is poor electrical connections. Because of this, the conditions under which the incident
occurred may not be clear. Therefore, circuit checks made as part of the standard diagnostic procedure may
not indicate the specific malfunctioning area.
Common Intermittent Incidents Report Situations
STEP in Work Flow

The CONSULT-II is used. The SELF-DIAG RESULTS screen shows time data other than [0] or [1t].

Ground Inspection
UBS00I0T
A
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground
connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can
become an unwanted resistance. This unwanted resistance can change the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasti- EC
cally affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even
when the ground connection looks clean, there can be a thin film of rust on the surface.
When inspecting a ground connection follow these rules:
C
●
Remove the ground bolt or screw.
●
Inspect all mating surfaces for tarnish, dirt, rust, etc.
D
●
Clean as required to assure good contact.
●
Reinstall bolt or screw securely.
●
Inspect for “add-on” accessories which may be interfering with the ground circuit.
●
If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the E
wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.

Description
PFP:23710
UBS00I0U
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid
valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to
increase engine torque in low/mid speed range and output in high-speed range.

DTC P0075, P0081 IVT CONTROL SOLENOID VALVE
Component Description
PFP:23796
A
UBS00NOX
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.

DTC P0101 MAF SENSOR
Component Description
PFP:22680
UBS00I1C
The mass air flow sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake
flow. The mass air flow sensor controls the temperature of the hot
wire to a certain amount. The heat generated by the hot wire is
reduced as the intake air flows around it. The more air, the greater
the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.

UBS00I27
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are
a kind of potentiometers which transform the throttle valve position
into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the
throttle valve and feed the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the
throttle valve opening angle properly in response to driving condition.

[VQ]
DTC P0130, P0150 A/F SENSOR 1
Component Description
PFP:22693
UBS00NP0
The A/F sensor is a planar dual-cell limit current sensor. The sensor
element of the A/F sensor is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, which transports
ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range (0.7 <
< air).
The exhaust gas components diffuse through the diffusion gap at the
electrode of the oxygen pump and Nernst concentration cell, where
they are brought to thermodynamic balance.
SEF579Z
An electronic circuit controls the pump current through the oxygenpump cell so that the composition of the exhaust gas in the diffusion
gap remains constant at = 1. Therefore, the A/F sensor is able to
indicate air/fuel ratio by this pumping of current. In addition, a heater
is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).

DTC P0132, P0152 A/F SENSOR 1
Component Description
PFP:22693
A
UBS00NP7
The A/F sensor is a planar dual-cell limit current sensor. The sensor
element of the A/F sensor is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, which transports
ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range (0.7 <
< air).
The exhaust gas components diffuse through the diffusion gap at the
electrode of the oxygen pump and Nernst concentration cell, where
they are brought to thermodynamic balance.
EC
C
D
SEF579Z
E
An electronic circuit controls the pump current through the oxygenpump cell so that the composition of the exhaust gas in the diffusion
gap remains constant at = 1. Therefore, the A/F sensor is able to
indicate air/fuel ratio by this pumping of current. In addition, a heater
is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).

To judge the malfunction of air fuel ratio (A/F) sensor 1, this diagnosis measures response time of the A/F signal computed by ECM from the air fuel ration (A/F) sensor 1 signal. The time is compensated by engine operating (speed and load), fuel feedback control constant, and the air fuel ration (A/F) sensor 1 temperature
index. Judgment is based on whether the compensated time (the A/F signal cycling time index) is inordinately
long or not.

Component Description
PFP:226A0
UBS00I9K
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas on each bank.
Even if switching characteristics of the air fuel ratio (A/F) sensor 1
are shifted, the air-fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions.
Under normal conditions the heated oxygen sensor 2 is not used for
engine control operation.

The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the heated oxygen sensor 1. The oxygen
storage capacity of the three way catalyst (manifold) causes the
longer switching time. To judge the malfunctions of heated oxygen
sensor 2, ECM monitors whether the maximum voltage of the sensor
is sufficiently high during the various driving condition such as fuelcut.

Component Description
PFP:226A0
A
UBS00I34
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas on each bank.
Even if switching characteristics of the air fuel ratio (A/F) sensor 1
are shifted, the air-fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2.
This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions.
Under normal conditions the heated oxygen sensor 2 is not used for
engine control operation.

On Board Diagnosis Logic
UBS00I36
The heated oxygen sensor 2 has a much longer switching time
between rich and lean than the air fuel ratio (A/F) sensor 1. The oxygen storage capacity before the three way catalyst (manifold) causes
the longer switching time. To judge the malfunctions of heated oxygen sensor 2, ECM monitors whether the switching response of the
sensor's voltage is faster than specified during the various driving
condition such as fuel-cut.

With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the
theoretical mixture ratio based on the mixture ratio feedback signal from the A/F sensors 1. The ECM calcu- EC
lates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the

In case the amount of the compensation value is extremely large (The actual mixture ratio is too rich.), the
ECM judges the condition as the fuel injection system malfunction and lights up the MIL (2 trip detection logic).

DTC P0222, P0223 TP SENSOR
Component Description
PFP:16119
UBS00I3Z
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are
a kind of potentiometers which transform the throttle valve position
into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the
throttle valve and feed the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the
throttle valve opening angle properly in response to driving condition.

FAIL-SAFE MODE
When the malfunction is detected, ECM enters fail-safe mode an the MIL lights up.
Engine operation condition in fail-safe mode
The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10
degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.

On Board Diagnosis Logic
A
UBS00I47
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crank- EC
shaft position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is occurring.
Sensor

On board diagnosis of misfire
The misfire detection logic consists of the following two conditions.
1. One Trip Detection Logic (Three Way Catalyst Damage)
On the first trip that a misfire condition occurs that can damage the three way catalyst (TWC) due to overheating, the MIL will blink.
When a misfire condition occurs, the ECM monitors the CKP sensor signal every 200 engine revolutions
for a change.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will turn off.
If another misfire condition occurs that can damage the TWC on a second trip, the MIL will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will remain on.
If another misfire condition occurs that can damage the TWC, the MIL will begin to blink again.
2. Two Trip Detection Logic (Exhaust quality deterioration)
For misfire conditions that will not damage the TWC (but will affect vehicle emissions), the MIL will only
light when the misfire is detected on a second trip. During this condition, the ECM monitors the CKP sensor signal every 1,000 engine revolutions.
A misfire malfunction can be detected on any one cylinder or on multiple cylinders.

DTC P0335 CKP SENSOR (POS)
Component Description
PFP:23731
UBS00I4H
The crankshaft position sensor (POS) is located on the oil pan facing
the gear teeth (cogs) of the signal plate. It detects the fluctuation of
the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
ECM receives the signals as shown in the figure.

UBS00I4P
The camshaft position sensor (PHASE) senses the retraction of
camshaft (intake) to identify a particular cylinder. The camshaft position sensor (PHASE) senses the piston position.
When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor (PHASE) provides various controls of engine parts instead, utilizing timing of cylinder identification
signals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor changes.

DTC P0400 EGR FUNCTION
[VQ]
COMPONENT DESCRIPTION
EGR Volume Control Valve
A
The EGR volume control valve uses a step motor to control the flow
rate of EGR from exhaust manifold. This motor has four winding
phases. It operates according to the output pulse signal of the ECM.
Two windings are turned ON and OFF in sequence. Each time an
ON pulse is issued, the valve opens or closes, changing the flow
rate. When no change in the flow rate is needed, the ECM does not
issue the pulse signal. A certain voltage signal is issued so that the
valve remains at that particular opening.
EC
C
D
SEF552W
EGR Temperature Sensor
E
The EGR temperature sensor detects temperature changes in the
EGR passageway. When the EGR volume control valve opens, hot
exhaust gases flow, and the temperature in the passageway
changes. The EGR temperature sensor is a thermistor that modifies
a voltage signal sent from the ECM. This modified signal then
returns to the ECM as an input signal. As the temperature increases,
EGR temperature sensor resistance decreases.
This sensor is not directly used to control the engine system. It is
used only for the on board diagnosis.

The ECM monitors the switching frequency ratio of air fuel ratio (A/F)
sensor 1 and heated oxygen sensor 2.
A three way catalyst (manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of air fuel ration (A/F) sensor 1 and heated
oxygen sensor 2 approaches a specified limit value, the three way
catalyst (manifold) malfunction is diagnosed.

*1: ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to the ECM through CAN communication line.
This system controls flow rate of fuel vapor from the EVAP canister. The opening of the vapor by-pass passage in the EVAP canister purge volume control solenoid valve changes to control the flow rate. The EVAP
canister purge volume control solenoid valve repeats ON/OFF operation according to the signal sent from the
ECM. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is
determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapor
from the EVAP canister is regulated as the air flow changes.
COMPONENT DESCRIPTION
The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount of fuel vapor that will flow through the valve.

DTC P0447 EVAP CANISTER VENT CONTROL VALVE
Component Description
PFP:14935
A
UBS00I61
The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.
This solenoid valve responds to signals from the ECM. When the
ECM sends an ON signal, the coil in the solenoid valve is energized.
A plunger will then move to seal the canister vent. The ability to seal
the vent is necessary for the on board diagnosis of other evaporative
emission control system components.
This solenoid valve is used only for diagnosis, and usually remains
opened.
When the vent is closed, under normal purge conditions, the evaporative emission control system is depressurized and allows EVAP
Control System diagnosis.

The fuel level sensor is mounted in the fuel level sensor unit. The
sensor detects a fuel level in the fuel tank and transmits a signal to
the combination meter. The combination meter sends the fuel level
sensor signal to the ECM through CAN communication line.
It consists of two parts, one is mechanical float and the other is variable resistor. Fuel level sensor output voltage changes depending on
the movement of the fuel mechanical float.

DTC P0506 ISC SYSTEM
Description
PFP:23781
UBS00I7J
NOTE:
If DTC P0506 is displayed with other DTC, first perform the trouble diagnosis for the other DTC.
The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idling speed. The crankshaft position sensor (POS) detects
the actual engine speed and sends a signal to the ECM.
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value
memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.
The optimum value stored in the ECM is determined by taking into consideration various engine conditions,
such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan
operation, etc.).

Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are
a kind of potentiometers which transform the throttle valve position
into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the
throttle valve and feed the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the
throttle valve opening angle properly in response to driving condition.

*1: This signal is sent to the ECM through CAN communication line.
*2: ECM determines the start signal status by the signals of engine speed and battery voltage.
This system controls flow rate of EGR led from exhaust manifold to intake manifold. The opening of the EGR
by-pass passage in the EGR volume control valve changes to control the flow rate. A built-in step motor
moves the valve in steps corresponding to the ECM output pulses. The opening of the valve varies for optimum engine control. The optimum value stored in the ECM is determined by considering various engine conditions. The EGR volume control valve remains closed under the following conditions.

DTC P1402 EGR FUNCTION
[VQ]
COMPONENT DESCRIPTION
EGR Volume Control Valve
A
The EGR volume control valve uses a step motor to control the flow
rate of EGR from exhaust manifold. This motor has four winding
phases. It operates according to the output pulse signal of the ECM.
Two windings are turned ON and OFF in sequence. Each time an
ON pulse is issued, the valve opens or closes, changing the flow
rate. When no change in the flow rate is needed, the ECM does not
issue the pulse signal. A certain voltage signal is issued so that the
valve remains at that particular opening.
EC
C
D
SEF552W
EGR Temperature Sensor
E
The EGR temperature sensor detects temperature changes in the
EGR passageway. When the EGR volume control valve opens, hot
exhaust gases flow, and the temperature in the passageway
changes. The EGR temperature sensor is a thermistor that modifies
a voltage signal sent from the ECM. This modified signal then
returns to the ECM as an input signal. As the temperature increases,
EGR temperature sensor resistance decreases.
This sensor is not directly used to control the engine system. It is
used only for the on board diagnosis.

NOTE:
●
Diagnosis for this DTC will occur when engine coolant temperature is below 50 to 60°C (122 to 140°F).
Therefore, it will be better to turn ignition switch ON (start engine) at the engine coolant temperature below
30°C (86°F) when starting DTC confirmation procedure.
●
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait
at least 10 seconds before conducting the next test.
TESTING CONDITION:
●
Always perform the test at a temperature above −10°C (14°F).
●
Engine coolant temperature and EGR temperature must be
verified in “DATA MONITOR” mode with CONSULT-II before
starting DTC WORK SUPPORT test. If it is out of range
below, the test cannot be conducted.

The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelerator position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometers which transform the accelerator pedal
position into output voltage, and emit the voltage signal to the ECM.
In addition, these sensors detect the opening and closing speed of
the accelerator pedal and feed the voltage signals to the ECM. The
ECM judges the current opening angle of the accelerator pedal from
these signals and controls the throttle control motor based on these
signals.

Idle position of the accelerator pedal is determined by the ECM
receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation such as fuel cut.

[VQ]
DTC P2A00, P2A03 A/F SENSOR 1
Component Description
PFP:22693
A
UBS00IB2
The A/F sensor is a planar dual-cell limit current sensor. The sensor
element of the A/F sensor is the combination of a Nernst concentration cell (sensor cell) with an oxygen-pump cell, which transports
ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range (0.7 <
< air).
The exhaust gas components diffuse through the diffusion gap at the
electrode of the oxygen pump and Nernst concentration cell, where
they are brought to thermodynamic balance.
EC
C
D
SEF579Z
E
An electronic circuit controls the pump current through the oxygenpump cell so that the composition of the exhaust gas in the diffusion
gap remains constant at = 1. Therefore, the A/F sensor is able to
indicate air/fuel ratio by this pumping of current. In addition, a heater
is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).

FUEL INJECTOR
Component Description
PFP:16600
UBS00IEY
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse duration. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.

*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for 1 second after the ignition switch is turned ON to improve engine startability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows that
the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the
ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging,
thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump
relay, which in turn controls the fuel pump.

*: ECM determines the start signal status by the signals of engine speed and battery voltage.
PBIB1822E
When the engine is running at medium speed, the ECM sends the ON signal to the VIAS control solenoid
valve. This signal introduces the intake manifold vacuum into the power valve actuator and therefore closes
the power valve.
Under this condition, the effective intake manifold length is equivalent to the total length of passage A and passage B. This long intake manifold provides increased amount of intake air, which results in improved suction
efficiency and higher torque.
When engine is running at low or high speed, the ECM sends the OFF signal to the VIAS control solenoid
valve and the power valve is opened.
Under this condition, the effective intake manifold length is equivalent to the length of passage B. This shortened intake manifold length results in enhanced engine output due to reduced suction resistance under high
speeds.
COMPONENT DESCRIPTION
Power Valve
The power valve is installed in intake manifold collector and used to
control the suction passage of the variable induction air control system. It is set in the fully closed or fully opened position by the power
valve actuator (1) operated by the vacuum stored in the surge tank.

VIAS Control Solenoid Valve
The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to A
ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut.
When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the
power valve actuator.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EIS003MB
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

H
get in the way with cloth.
When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
Keep removed parts protected with cloth.
EI
If a clip is deformed or damaged, replace it.
If an unreusable part is removed, replace it with a new one.
Tighten bolts and nuts firmly to the specified torque.
J
After re-assembly has been completed, make sure each part functions correctly.
Remove stains in the following way.
K
Water-soluble stains:
Dip a cloth in warm water, and squeeze tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the L
stain with the cloth. Next, dip the soft cloth in fresh water, and then squeeze it tightly. Then clean off the
detergent completely. Then wipe the area with a soft dry cloth.
Do not use any organic solvent, such as thinner or benzine.

CUSTOMER INTERVIEW
Interview the customer, if possible, to determine the conditions that exist when the noise occurs. Use the Diag- H
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to EI-9, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
EI
●
The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
●
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
J
is concerned about. This can be accomplished by test driving the vehicle with the customer.
●
After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
K
defining the noise.
–
Squeak — (Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surL
faces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping
–
Creak — (Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
M
–
Rattle — (Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
–
Knock — (Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
–
Tick — (Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
–
Thump — (Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
–
Buzz — (Like a bumblebee)
Buzz characteristics include high frequency rattle/firm contact.
●
Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.
●
Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following:
●
Close a door.
●
Tap or push/pull around the area where the noise appears to be coming from.
●
Rev the engine.
●
Use a floor jack to recreate vehicle “twist”.
●
At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
●
Raise the vehicle on a hoist and hit a tire with a rubber hammer.
●
Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
●
If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1.
2.
Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear: J-39565 and mechanics stethoscope).
Narrow down the noise to a more specific area and identify the cause of the noise by:
● Removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fasteners
can be broken or lost during the repair, resulting in the creation of new noise.
● Tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only temporarily.
● Feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing
the noise.
● Placing a piece of paper between components that you suspect are causing the noise.
● Looking for loose components and contact marks.
Refer to EI-7, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
If the cause is a loose component, tighten the component securely.
If the cause is insufficient clearance between components:
–
Separate components by repositioning or loosening and retightening the component, if possible.
–
Insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through your authorized NISSAN
Parts Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISSAN Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
H
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
EI
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
J
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by K
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness.
L
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
M
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise.
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EBS00Z4V
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along EM
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
F
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
G
Precautions for Draining Coolant
●
EBS00J4A
Drain coolant when engine is cooled.
Precautions for Disconnecting Fuel Piping
●
●
●
Before starting work, make sure no fire or spark producing items are in the work area.
Release fuel pressure before any removal or disassembly.
After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and Disassembly

Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way,
and replace if necessary.
Precautions for Assembly and Installation
●
I
When instructed to use special service tools, use the specified tools. Always be careful to work safely,
avoid forceful operations.
Use maximum care to avoid damage to mating or sliding surfaces.
Cover openings of engine system with tape or equivalent, if necessary, to seal out foreign materials.
Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, follow the specifications.
Precautions for Inspection, Repair and Replacement
●
H
EBS00J4B
EBS00J4E
Use torque wrench to tighten bolts or nuts.
When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified, follow the specifications.
Always replace the old with a new gasket, packing, oil seal or O-ring.
Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
Bleed the air trapped within the system after draining the coolant.
Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine
stopped). Then make sure that there are no leaks at fuel line connections.

●
●
●
EBS00J4F
Use an angle wrench for the final tightening of the following engine parts.
Cylinder head bolts
Lower cylinder block bolts
Connecting rod cap bolts
Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)
Do not use a torque value for final tightening.
The torque value for these parts are for a preliminary step.
Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions for Liquid Gasket
EBS00J4G
REMOVAL OF LIQUID GASKET SEALING
●
After removing the bolts and nuts, separate the mating surface
and remove the sealant using Tool.
Tool number
: KV10111100 (J-37228)
CAUTION:
Be careful not to damage the mating surfaces.
●
In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap (1) the cutter where the RTV Silicone Sealant is
applied. Use a plastic hammer to slide the cutter (2) by tapping
on the side.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating surfaces.
PBIC0002E
LIQUID GASKET APPLICATION PROCEDURE

3.
4.
Using a scraper, remove the old Silicone RTV Sealant adhering
to the gasket application surface and the mating surface.
● Remove the sealant completely from the groove of the gasket
application surface, mounting bolts, and bolt holes.
Thoroughly clean the gasket application surface and the mating
surface and remove adhering moisture, grease and foreign
materials.
Attach the sealant tube to the tube presser.
Use Genuine Silicone RTV Sealant or equivalent. Refer to
GI-45, "RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .

If compression pressure is below minimum value, check valve clearances and parts associated with combustion chamber (valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head gasket). After the checking, measure compression pressure again.
●
If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
●
If the added engine oil improves the compression, the piston rings may be worn or damaged. Check the
piston rings and replace if necessary.

HOW TO SELECT A MAIN BEARING
When New Cylinder Block and Crankshaft are Used:
1.
"Main Bearing Selection Table" rows correspond to bearing
housing grade on rear left side of cylinder block.
● If there is a corrected stamp mark on the cylinder block, use it
as a correct reference.

2.
Apply journal diameter grade stamped on crankshaft front side
to column in "Main Bearing Selection Table".
KBIA0073E
3.
4.
Find value at crossing of row and column in "Main Bearing Selection Table".
CAUTION:
● There are two main bearing selection tables. One is for odd-numbered journals (1, 3, and 5) and
the other is for even-numbered journals (2 and 4). Make certain to use the appropriate table.
This is due to differences in the specified clearances.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EBS00Z4W
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along EM
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front C
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
F
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
G
Precautions for Drain Coolant

Use torque wrench to tighten bolts or nuts to specification.
When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified, do exactly as specified.
Replace with new gasket, packing, oil seal or O-ring.
Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
Release air within route after draining coolant.

Remove oil and dust on the crankshaft pin and the surfaces of
each bearing completely.
Cut a Plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.
Install the connecting rod bearings to the connecting rod cap,
and tighten the connecting rod nuts to the specified torque.
CAUTION:
Never rotate the crankshaft.
Remove the connecting rod cap and bearings, and using the
scale on the Plastigage bag, measure the Plastigage width.

●
Be careful not to cut your hand on the insulator edges.
●
If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insulator, clean and inspect the insulator.
C
●
When installing the insulator avoid large gaps or interference between the insulator and each
exhaust pipe.
●
Remove deposits from the sealing surface of each connection. Connect them securely to avoid D
exhaust gas leaks.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EBS00QUV
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EES0024N
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions
●
●
●
EES0016W
When installing rubber parts, final tightening must be carried out under unladen condition* with
tires on ground.
Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
*: Fuel, engine coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
After installing removed suspension parts, check wheel alignment and adjust if necessary.
Lock nuts are unreusable parts; always use new ones.
When replacing, do not wipe the oil off the new lock nut before tightening.

GENERAL INFORMATION AND RECOMMENDATIONS
1.
2.
B
A Four-Wheel Thrust Alignment should be performed.
● This type of alignment is recommended for any NISSAN vehicle.
● The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
C
is centered.
● The alignment machine itself should be capable of accepting any NISSAN vehicle.
● The alignment machine should be checked to ensure that it is level.
D
Make sure the alignment machine is properly calibrated.
● Your alignment machine should be regularly calibrated in order to give correct information.
● Check with the manufacturer of your specific alignment machine for their recommended Service/Cali- FSU
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-18, "Front
Wheel Alignment (Unladen*1)" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
● The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.
● This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “compensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
● Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
● See Instructions in the alignment machine you are using for more information.

Description
PFP:00001
GI
EAS0018O
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
B
EAS002EK
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for NVIS/IVIS (NISSAN/INFINITI VEHICLE IMMOBILIZER SYSTEM NATS) (If Equipped)
EAS001QJ
NVIS/IVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS/IVIS
(NATS).
Both of the originally supplied ignition key IDs have been NVIS/IVIS (NATS) registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NVIS/IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.
●
When NVIS/IVIS (NATS) detects trouble, the security indicator lamp lights up while ignition switch is in
"ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.
●
When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
other NVIS/IVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II NVIS/IVIS (NATS)
software is necessary.
Regarding the procedures of NVIS/IVIS (NATS) initialization and NVIS/IVIS (NATS) ignition key ID registration, refer to CONSULT-II operation manual, NVIS/IVIS (NATS).
Therefore, CONSULT-II NVIS/IVIS (NATS) software (program card and operation manual) must be kept
strictly confidential to maintain the integrity of the anti-theft function.
●
When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
other NVIS/IVIS (NATS) ignition key IDs), it may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A maximum of four or five key IDs can be registered into NVIS/IVIS (NATS).
●
When failing to start the engine first time using the key of NVIS/IVIS (NATS), start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.

HOW TO PROBE CONNECTORS
Connector damage and an intermittent connection can result from improperly probing of the connector during
circuit checks.
The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the connector, follow the procedures below using a “T” pin. For the best contact grasp the “T” pin using an alligator
clip.
Probing from Harness Side
Standard type (not waterproof type) connector should be probed
from harness side with “T” pin.
●
If the connector has a rear cover such as a ECM connector,
remove the rear cover before probing the terminal.
●
Do not probe waterproof connector from harness side. Damage
to the seal between wire and connector may result.
SGI841
Probing from Terminal Side
FEMALE TERMINAL
●
There is a small notch above each female terminal. Probe each
terminal with the “T” pin through the notch.
Do not insert any object other than the same type male terminal
into female terminal.

Waterproof Connector Inspection
If water enters the connector, it can short interior circuits. This may lead to intermittent problems.
Check the following items to maintain the original waterproof characteristics.
RUBBER SEAL INSPECTION
●
Most waterproof connectors are provided with a rubber seal
between the male and female connectors. If the seal is missing,
the waterproof performance may not meet specifications.
●
The rubber seal may come off when connectors are disconnected. Whenever connectors are reconnected, make sure the
rubber seal is properly installed on either side of male or female
connector.
SEL275V
WIRE SEAL INSPECTION
The wire seal must be installed on the wire insertion area of a waterproof connector. Be sure that the seal is
installed properly.
Terminal Lock Inspection
Check for unlocked terminals by pulling wire at the end of connector.
An unlocked terminal may create intermittent signals in the circuit.

INCIDENT SIMULATION TESTS
Introduction
Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The following section illustrates ways to simulate the conditions/environment under which the owner experiences an
electrical incident.
The section is broken into the six following topics:
●
Vehicle vibration
●
Heat sensitive

●
Cold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
●
Vehicle Vibration
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustration.
CONNECTORS & HARNESS
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
HINT
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector terminals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
SENSORS & RELAYS
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
SGI839
ENGINE COMPARTMENT
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:
●
Connectors not fully seated.
●
Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
●
Wires laying across brackets or moving components.
●
Loose, dirty or corroded ground wires.
●
Wires routed too close to hot components.
To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previously explained. Using the wiring diagrams inspect the
wiring for continuity.
BEHIND THE INSTRUMENT PANEL
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehicle vibration can aggravate a harness which is routed along a bracket or near a screw.
UNDER SEATING AREAS
Revision: November 2006
GI-28
2006 Altima
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or GI
pinching.
Heat Sensitive
B
The customer's concern may occur during hot weather or after car
has sat for a short time. In such cases you will want to check for a
heat sensitive condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat components above 60°C (140°F). If incident occurs
while heating the unit, either replace or properly insulate the component.
C
D
SGI842
E
Freezing
The customer may indicate the incident goes away after the car
warms up (winter time). The cause could be related to water freezing
somewhere in the wiring/electrical system.
There are two methods to check for this. The first is to arrange for
the owner to leave his car overnight. Make sure it will get cold
enough to demonstrate his complaint. Leave the car parked outside
overnight. In the morning, do a quick and thorough diagnosis of
those electrical components which could be affected.
The second method is to put the suspect component into a freezer
long enough for any water to freeze. Reinstall the part into the car
and check for the reoccurrence of the incident. If it occurs, repair or
replace the component.
F
G
H
SGI843
I
Water Intrusion
The incident may occur only during high humidity or in rainy/snowy
weather. In such cases the incident could be caused by water intrusion on an electrical part. This can be simulated by soaking the car
or running it through a car wash.
Do not spray water directly on any electrical components.
J
K
L
SGI844
Electrical Load
The incident may be electrical load sensitive. Perform diagnosis with
all accessories (including A/C, rear window defogger, radio, fog
lamps) turned on.
SGI845
Cold or Hot Start Up
On some occasions an electrical incident may occur only when the car is started cold, or it may occur when
the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to
make a proper diagnosis.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
CIRCUIT INSPECTION
Introduction
In general, testing electrical circuits is an easy task if it is approached in a logical and organized method.
Before beginning it is important to have all available information on the system to be tested. Also, get a thorough understanding of system operation. Then you will be able to use the appropriate equipment and follow
the correct test procedure.
You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring harness or electrical component to do this.
OPEN
A circuit is open when there is no continuity through a section of the circuit.
There are two types of shorts.
SHORT
●
SHORT CIRCUIT
When a circuit contacts another circuit and causes the normal resistance to
change.
●
SHORT TO GROUND
When a circuit contacts a ground source and grounds the circuit.
NOTE:
Refer to “How to Check Terminal” to probe or check terminal.
Testing for “Opens” in the Circuit
Before you begin to diagnose and test the system, you should rough sketch a schematic of the system. This
will help you to logically walk through the diagnosis process. Drawing the sketch will also reinforce your working knowledge of the system.
SGI846-A
CONTINUITY CHECK METHOD
The continuity check is used to find an open in the circuit. The digital multimeter (DMM) set on the resistance
function will indicate an open circuit as over limit (no beep tone or no ohms symbol). Make sure to always start
with the DMM at the highest resistance level.
To help in understanding the diagnosis of open circuits, please refer to the previous schematic.
●
Disconnect the battery negative cable.
●
Start at one end of the circuit and work your way to the other end. (At the fuse block in this example)
●
Connect one probe of the DMM to the fuse block terminal on the load side.
●
Connect the other probe to the fuse block (power) side of SW1. Little or no resistance will indicate that
portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an
over limit or infinite resistance condition. (point A)
●
Connect the probes between SW1 and the relay. Little or no resistance will indicate that portion of the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or infinite resistance condition. (point B)
●
Connect the probes between the relay and the solenoid. Little or no resistance will indicate that portion of
the circuit has good continuity. If there were an open in the circuit, the DMM would indicate an over limit or
infinite resistance condition. (point C)
Any circuit can be diagnosed using the approach in the previous example.
VOLTAGE CHECK METHOD
To help in understanding the diagnosis of open circuits please refer to the previous schematic.
In any powered circuit, an open can be found by methodically checking the system for the presence of voltage.
This is done by switching the DMM to the voltage function.
Revision: November 2006
GI-30
2006 Altima
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
Connect one probe of the DMM to a known good ground.
●
Begin probing at one end of the circuit and work your way to the other end.

Ground Inspection
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground
connections are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can
become an unwanted resistance. This unwanted resistance can change the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically affect an electronically controlled circuit. A poor or corroded ground can easily affect the circuit. Even
when the ground connection looks clean, there can be a thin film of rust on the surface.
When inspecting a ground connection follow these rules:
●
Remove the ground bolt or screw.
●
Inspect all mating surfaces for tarnish, dirt, rust, etc.
●
Clean as required to assure good contact.
●
Reinstall bolt or screw securely.
●
Inspect for “add-on” accessories which may be interfering with the ground circuit.
●
If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the
wires are clean, securely fastened and providing a good ground path. If multiple wires are cased in one
eyelet make sure no ground wires have excess wire insulation.
For detailed ground distribution information, refer to “Ground Distribution” in PG section.
SGI853
Voltage Drop Tests
Voltage drop tests are often used to find components or circuits which have excessive resistance. A voltage
drop in a circuit is caused by a resistance when the circuit is in operation.
Check the wire in the illustration. When measuring resistance with DMM, contact by a single strand of wire will
give reading of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire
is not able to carry the current. The single strand will have a high resistance to the current. This will be picked
up as a slight voltage drop.
Unwanted resistance can be caused by many situations as follows:
●
Undersized wiring (single strand example)
●
Corrosion on switch contacts
●
Loose wire connections or splices.
If repairs are needed always use wire that is of the same or larger gauge.
MEASURING VOLTAGE DROP — ACCUMULATED METHOD
Revision: November 2006
GI-32

G
SGI974
MEASURING VOLTAGE DROP — STEP-BY-STEP
The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in
“Computer Controlled Systems”).
Circuits in the “Computer Controlled System” operate on very low amperage.
The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the
system. Such resistance variation may be caused by poor connection, improper installation, improper wire
gauge or corrosion.
The step by step voltage drop test can identify a component or wire with too much resistance.

CAUTION:
●
Never tow an automatic transaxle model with the rear wheels raised and the front wheels on the
ground. This may cause serious and expensive damage to the transaxle. If it is necessary to tow
the vehicle with the rear wheels raised, always use towing dollies under the front wheels.
●
Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
NISSAN recommends that the vehicle be towed with the driving
(front) wheels off the ground as illustrated.
CAUTION:
●
Always release the parking brake when towing the vehicle
with the front wheels raised with the rear wheels on the
ground.
●
When towing manual transaxle models with the front
wheels on the ground (if a towing dolly is not used), turn
the ignition key to the OFF position, and secure the steering
wheel in the straight-ahead position with a rope or similar
device. Never place the ignition key in the LOCK position.
This will result in damage to the steering lock mechanism.
Move the shift lever to the N (Neutral) position.

Vehicle Recovery (Freeing a stuck vehicle)
EAS0019J
Front
●
Use the towing hook only, not other parts of the vehicle. Otherwise, the vehicle body will be damaged.
●
Use the towing hook only to free a vehicle stuck in sand, snow,
mud, etc. Never tow the vehicle for a long distance using only
the towing hook.
●
The towing hook is under tremendous force when used to free a
stuck vehicle. Always pull the cable straight out from the front or
rear of the vehicle. Never pull on the hook at an angle.
●
Stand clear of a stuck vehicle.
Rear
LAIA0025E
●
Tow chains or cables must be attached only to the main structural members of the vehicle.
●
Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or cooling systems.
●
Always pull the cable straight out from the front or rear of the vehicle. Never pull on the vehicle at an
angle.
●
Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or recovery.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EIS003KH
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

EIS003KI
Do not use an adhesive which is past its usable date. Shelf life of this product is limited to six months after G
the date of manufacture. Carefully adhere to the expiration or manufacture date printed on the box.
Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.
Open the seal of the primer and adhesive just before application. Discard the remainder.
H
Before application, be sure to shake the primer container to stir the contents. If any floating material is
found, do not use it.
If any primer or adhesive contacts the skin, wipe it off with gasoline or equivalent and wash the skin with GW
soap.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag- H
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to GW-9, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
GW
●
The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
●
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
J
is concerned about. This can be accomplished by test driving the vehicle with the customer.
●
After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
K
defining the noise.
●
Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surL
faces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
●
Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
M
●
Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
●
Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
●
Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
●
Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
●
Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
●
Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.
●
Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
●
Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
●
If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1.
2.
●
●
●
●
●
Narrow down the noise to a general area.To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear: J-39565 and mechanic's stethoscope).
Narrow down the noise to a more specific area and identify the cause of the noise by:
removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be broken or lost during the repair, resulting in the creation of new noise.
tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.
feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
placing a piece of paper between components that you suspect are causing the noise.
looking for loose components and contact marks.
Refer to GW-7, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
If the cause is a loose component, tighten the component securely.
●
If the cause is insufficient clearance between components:
–
separate components by repositioning or loosening and retightening the component, if possible.
–
insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through your authorized NISSAN
Parts Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISSAN Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.
URETHANE PADS [1.5 mm (0.059 in) thick]

Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle Troubleshooting
EIS0048B
F
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
G
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
H
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
GW
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
J
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring harK
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
L
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
M
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise.
Revision: November 2006
GW-7

SQUEAK AND RATTLE TROUBLE DIAGNOSES
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lense loose.
3. Loose screws at console attachment points.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

During raising operation of driver or passenger power window (if equipped), if door control module detects that
foreign object is pinched, power window lowers approximately 150 mm (5.91 in).
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to power window, it
may lower.
Operation conditions

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS003N1
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

CUSTOMER INTERVIEW
Interview the customer, if possible, to determine the conditions that exist when the noise occurs. Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to IP-8, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
●
The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
●
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.
●
After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
–
Squeak — (Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
–
Creak — (Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
–
Rattle — (Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
–
Knock — (Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
–
Tick — (Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
–
Thump — (Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
–
Buzz — (Like a bumblebee)
Buzz characteristics include high frequency rattle/firm contact.
●
Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.
●
Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following:
1. Close a door.
2. Tap or push/pull around the area where the noise appears to be coming from.
3. Rev the engine.
4. Use a floor jack to recreate vehicle “twist”.
5. At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6. Raise the vehicle on a hoist and hit a tire with a rubber hammer.
●
Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
●
If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.

F
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
G
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1.
2.
Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool H
(Chassis Ear: J-39570, Engine Ear: J-39565 and mechanics stethoscope).
Narrow down the noise to a more specific area and identify the cause of the noise by:
IP
● Removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fasteners
can be broken or lost during the repair, resulting in the creation of new noise.
● Tapping or pushing/pulling the component that you suspect is causing the noise.
J
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only temporarily.
● Feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing
K
the noise.
● Placing a piece of paper between components that you suspect are causing the noise.
● Looking for loose components and contact marks.
L
Refer to IP-6, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
If the cause is a loose component, tighten the component securely.
●
If the cause is insufficient clearance between components:
–
Separate components by repositioning or loosening and retightening the component, if possible.
–
Insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through your authorized NISSAN
Parts Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISSAN Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle Troubleshooting
EIS0058V
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Revision: November 2006
IP-6
2006 Altima
SQUEAK AND RATTLE TROUBLE DIAGNOSIS
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise.
A
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise.
SUNROOF/HEADLINING
B
C
D
E
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
F
G
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of H
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
IP
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.
J
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
UKS001OF
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

CHECK POINTS FOR USING CONSULT-II
–
C
UKS001R6
When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1.
B
Do not apply voltage of 7.0 V or higher to the measurement terminals.
Use the tester with its open terminal voltage being 7.0 V or less.
Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before
checking the circuit.

System Description
PFP:23710
UKS001OC
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS008LD
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

EKS008LE
Never work with wet hands.
The xenon headlamp system includes a high voltage generating
part. Be sure to disconnect battery negative cable (negative terminal) or power fuse before removing, installing, or touching the
xenon headlamp (including lamp bulb).
Turn the lighting switch OFF before disconnecting and connecting the connector.
When turning the xenon headlamp on and while it is illuminated,
never touch the harness, bulb, and socket of the headlamp.
When checking the headlamp on/off operation, check it on vehiPKIA0183E
cle and with the power connected to the vehicle-side connector.
Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
Install the xenon headlamp bulb socket correctly. If it is installed
improperly, high-voltage leak or corona discharge may occur
that can melt the bulb, connector, and housing. Do not illuminate
the xenon headlamp bulb out of the headlamp housing. Doing
so can cause fire and harm your eyes.
When the bulb has burned out, wrap it in a thick vinyl bag and
discard. Do not break the bulb.
Leaving the bulb removed from the headlamp housing for a long
period of time can deteriorate the performance of the lens and
reflector (dirt, clouding). Always prepare a new bulb and have it
EL-3422D
on hand when replacing the bulb.
When adjusting the headlamp aiming, turn the aiming adjustment screw only in the tightening direction. (If it is necessary to loosen the screw, first fully loosen the
screw, and then turn it in the tightening direction.)
Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

System Description
EKS008LH
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
requesting the headlamps (and tail lamps) to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized,
these relays direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times
●
to headlamp high relay, located in the IPDM E/R, and
●
to headlamp low relay, located in the IPDM E/R, and
●
through 50A fusible link (letter f , located in the fuse and fusible link box)
●
to BCM terminal 70.
With the ignition switch in the ON or START position, power is supplied
●
through 10A fuse [No. 1, located in the fuse block (J/B)]
●
to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
●
through 10A fuse [No. 6, located in the fuse block (J/B)]
●
to BCM terminal 11.

Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This
input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R controls the headlamp low relay coil. When energized, this relay directs power
●
through 15A fuse (No. 36, located in the IPDM E/R)
●
through IPDM E/R terminal 20
●
to headlamp RH terminal 1, and
●
through 15A fuse (No. 45, located in the IPDM E/R)
●
through IPDM E/R terminal 30
●
to headlamp LH terminal 1.
Ground is supplied
●
to headlamp RH terminal 2
●
to headlamp LH terminal 2
●
through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input requesting the headlamp high beams to illuminate. This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH BEAM indicator.
The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power
●
through 10A fuse (No. 40, located in the IPDM E/R)
●
through IPDM E/R terminal 27
●
to headlamp RH terminal 1, and
●
through 10A fuse (No. 38, located in the IPDM E/R)
●
through IPDM E/R terminal 28
●
to headlamp LH terminal 1.
Ground is supplied
●
to headlamp RH terminal 2
●
to headlamp LH terminal 2
●
through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON) and the ignition switch is turned from
ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting
switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps
are turned off.
AUTO LIGHT OPERATION
Refer to LT-43, "System Description" for auto light operation.
XENON HEADLAMP (IF EQUIPPED)
The low beam headlamps may be equipped with xenon type bulbs. Xenon bulbs do not use a filament.
Instead, they produce light when a high voltage current is passed between two tungsten electrodes through a
mixture of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic
control of the power supply gives the headlamps stable quality and tone color.
Following are some of the advantages of the xenon type headlamp.
●
The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
●
Light output is nearly double that of halogen headlamps, affording increased area of illumination.
Revision: November 2006
LT-6
2006 Altima
HEADLAMP (FOR USA)
●
●
The light features a high relative spectral distribution at wavelengths to which the human eye is most sensitive. This means that even in the rain, more light is reflected back from the road surface toward the vehicle for added visibility.
Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.

System Description
EKS008M3
The headlamp system for Canada vehicles is equipped with a daytime light control unit that activates the high
beam headlamps at approximately half illumination whenever the engine is running. If the parking brake is
applied before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminate
once the parking brake is released. Thereafter, the daytime lights will continue to operate when the parking
brake is applied.
Battery saver system is controlled by the BCM (body control module).
Power is supplied at all times
●
to headlamp high relay located in the IPDM E/R (intelligent power distribution module engine room), and
●
through 50A fusible link (letter f , located in the fuse and fusible link box)

●
BATTERY SAVER CONTROL
With the combination switch (lighting switch) is in the 2ND position (ON) and the ignition switch is turned from
ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes unless the combination switch (lighting
switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps
are turned off.
AUTO LIGHT OPERATION
For auto light operation, refer to LT-43, "System Description" .

With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, power is
supplied
●
through daytime light control unit terminal 7

Because the high beam headlamps are now wired in series, they operate at half illumination.
XENON HEADLAMP (IF EQUIPPED)
The low beam headlamps may be equipped with xenon type bulbs. Xenon bulbs do not use a filament.
Instead, they produce light when a high voltage current is passed between two tungsten electrodes through a
mixture of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic
control of the power supply gives the headlamps stable quality and tone color.
Following are some of the advantages of the xenon type headlamp.
●
The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
●
Light output is nearly double that of halogen headlamps, affording increased area of illumination.
●
The light features a high relative spectral distribution at wavelengths to which the human eye is most sensitive. This means that even in the rain, more light is reflected back from the road surface toward the vehicle for added visibility.
●
Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
OPERATION
After starting the engine with the lighting switch in the "OFF" or 1ST position, the headlamp high beam automatically turns on. Lighting switch operations other than the above are the same as conventional light systems.

System Description
EKS008MC
This system automatically turns the parking lamps and the headlamps on and off in accordance with ambient
light.
Timing for when the lamps turn on/off can be selected using four modes.
L
OUTLINE
The auto light control system uses an optical sensor that detects the brightness of outside light.
When the lighting switch is in AUTO position, it automatically turns on/off the parking lamps and the headlamps (and fog lamps, if equipped) in accordance with the ambient light. Sensitivity can be adjusted in four
steps. For the details of the setting, refer to LT-49, "SETTING CHANGE FUNCTIONS" .
When the lighting switch is in "AUTO" position, power is supplied
●
through BCM (body control module) terminal 17
●
to auto light sensor terminal 1.
When lighting switch is in "AUTO" position, ground is supplied
●
to auto light sensor terminal 3
●
through BCM terminal 18.
When ignition switch is turned to "ON" or "START" position and when outside brightness is darker than prescribed level, input is supplied
●
through auto light sensor terminal 2
●
to BCM terminal 14.
The headlamps will then illuminate. For a description of headlamp operation, refer to LT-5, "System Description" .

AUTO LIGHT SYSTEM
BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the AUTO position, and the ignition switch is turned from
ON or ACC to OFF, and one of the doors is opened, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting
switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps
are turned off.
SHUT OFF DELAY
When the ignition switch is turned from ON to OFF while the auto light system is activated and the headlamps
are illuminated, the shut off delay feature is activated. Under this condition, the BCM no longer receives a voltage signal at terminal 38 and this starts the auto light shut off delay timer. The shut off delay timer is active
until one of the doors is opened or the combination switch (lighting switch) position is changed. If one of the
doors is opened, the shut off delay feature is deactivated and the battery saver control feature is activated. If
the combination switch (lighting switch) position is changed, the headlamps are turned off.

System Description

Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The lighting switch must be in the AUTO position (with auto light system) or headlamps position (LOW beam is ON) for
front fog lamp operation. When the lighting switch is placed in the fog lamp position, the BCM (body control LT
module) receives input requesting the fog lamps to illuminate. This input is communicated to the IPDM E/R
(intelligent power distribution module engine room) across the CAN communication lines. The CPU (central
processing unit) of the IPDM E/R controls the front fog lamp relay coil. When energized, this relay directs L
power to the front fog lamps.
OUTLINE
M
Power is supplied at all times
●
through 15A fuse (No. 43, located in the IPDM E/R)
●
to front fog lamp relay, located in the IPDM E/R, and
●
through 50A fusible link (letter f, located in the fuse and fusible link box)
●
to BCM terminal 70.
When the ignition switch is in ON or START position, power is supplied
●
through 10A fuse [No. 1, located in the fuse block (J/B)]
●
to BCM terminal 38.
When the ignition switch is in ACC or ON position, power is supplied
●
through 10A fuse [No. 6, located in the fuse block (J/B)]

FRONT FOG LAMP
FOG LAMP OPERATION
The fog lamp switch is built into the combination switch. The lighting switch can only be in AUTO position (with
auto light system) or headlamps position (low beam is ON) and the fog lamp switch must be ON for fog lamp
operation.
With the fog lamp switch in the ON position, the CPU of the IPDM E/R grounds the coil side of the fog lamp
relay. The fog lamp relay then directs power
●
through IPDM E/R terminal 37
●
to front fog lamp LH terminal 1, and
●
through IPDM E/R terminal 36
●
to front fog lamp RH terminal 1.
Ground is supplied
●
to front fog lamp LH terminal 2
●
through grounds E15 and E24, and
●
to front fog lamp RH terminal 2
●
through grounds E15 and E24.
With power and grounds supplied, the front fog lamps illuminate.
BATTERY SAVER CONTROL
When the fog lamp switch is ON and the ignition switch is turned from ON to ACC or OFF, or if the ignition
switch is in the OFF position when the fog lamp switch is turned ON, the battery saver control feature is activated.
Under this condition, the fog lamps (and headlamps) remain illuminated for 5 minutes, unless the combination
switch (lighting switch) position is changed. If the combination switch (lighting switch) position is changed,
then the fog lamps (and headlamps) are turned off.

When the remote keyless entry system is triggered by input from the keyfob, the BCM supplies power
●
to front turn signal lamp LH terminal 3
●
to front turn signal lamp RH terminal 3
G
●
to rear turn signal lamp LH terminal 3
●
to rear turn signal lamp RH terminal 3.
Ground is supplied
H
●
to front turn signal lamp LH terminal 2
●

●
through grounds E15 and E24, and
I
●
to rear turn signal lamp LH terminal 5
●
to rear turn signal lamp RH terminal 5
J
●
through grounds B7 and B19.
The BCM sends a signal to combination meter across the CAN communication lines. This input is processed
by the CPU of the combination meter, which in turn supplies ground to the left and right turn signal indicator
lamps.
LT
With power and ground supplied, the BCM controls the flashing of the hazard warning lamps when keyfob is
used to activate the remote keyless entry system.

System Description
EKS008NW
J
Control of the parking, license plate, and tail lamp operation is dependent upon the position of the lighting
switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body control
module) receives input signal requesting the parking, license plate, and tail lamps to illuminate. This input sig- LT
nal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN
communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil.
When energized, this relay directs power to the parking, license plate, and tail lamps, which then illuminate.
L
Power is supplied at all times
●
through 10A fuse (No. 41, located in the IPDM E/R)
●
to tail lamp relay, located in the IPDM E/R, and
M
●
through 50A fusible link (letter f , located in the fuse and fusible link box)
●
to BCM terminal 70.
With the ignition switch in the ON or START position, power is supplied
●
through 10A fuse [No. 1, located in the fuse block (J/B)]
●
to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
●
through 10A fuse [No. 6, located in the fuse block (J/B)]
●
to BCM terminal 11.
Ground is supplied
●
to BCM terminal 67
●
through grounds F14, M57 and M61.
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1st or 2nd position (or if the auto light system is activated), the BCM receives
input signal requesting the parking, license plate, and tail lamps to illuminate. This input signal is communiRevision: November 2006

relay coil. When energized, this relay directs power
●
through terminal 22 of the IPDM E/R
●
to front combination lamp LH terminal 1

With power and ground supplied, the parking, license and tail lamps illuminate.
BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST (or 2ND) position and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the parking, license plate, and tail lamps remain illuminated for 5 minutes, unless the
combination switch (lighting switch) position is changed. If the combination switch (lighting switch) position is
changed, then the parking, license plate and tail lamps are turned off.

(with left front only power window anti-pinch system)
●
through main power window and door lock/unlock switch, power window and door lock/unlock switch RH
and front door lock assembly (key cylinder switch).
At the time that either front door is opened, BCM detects that door is unlocked. It determines that interior room
lamp timer operation conditions are met and turns the interior room lamp ON for 30 seconds.
When key is in ignition key cylinder (key switch ON), power is supplied
●
through key switch and key lock solenoid terminal 4
●
to BCM terminal 37.
When key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated. BCM
detects that key has been removed, determines that interior room lamp timer conditions are met and turns the
interior room lamp ON for 30 seconds.
When front door LH opens → closes and the key is not inserted in the key switch (key switch OFF), BCM terminal 47 changes between 0V (door open) → 12V (door closed). The BCM determines that conditions for interior room lamp operation are met and turns the interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
●
Front door LH is locked [when locked with keyfob, main power window and door lock/unlock switch, or
front door lock assembly (key cylinder switch)]

If interior lamp is left ON, it will not be turned out even when door is closed.
BCM turns off interior lamp automatically to save battery 30 minutes after ignition switch is turned OFF.
BCM controls interior lamps listed below:
●
Step lamp
●
Spot lamp
●
Trunk room lamp
●
Interior room lamp
●
Ignition keyhole illumination lamp
After lamps turn OFF by the battery saver system, the lamps illuminate again when
●
signal received from keyfob or main power window and door lock/unlock switch, or front door lock assembly (key cylinder switch) is locked or unlocked
●
door is opened or closed
●
key is removed from or inserted in ignition key cylinder.
Interior lamp battery saver control period can be changed by the function setting of CONSULT-II.

System Description
EKS008ON
Control of the illumination lamps operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated)
the BCM (body control module) receives input requesting the illumination lamps to illuminate. This input is
communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs power to the illumination lamps, which then illuminate.
Power is supplied at all times
●
through 10A fuse (No. 41, located in the IPDM E/R)
●
to tail lamp relay, located in the IPDM E/R, and
●
through 50A fusible link (letter f , located in the fuse and fusible link box)
●
to BCM terminal 70.
With the ignition switch in the ON or START position, power is supplied
●
through 10A fuse [No. 1, located in the fuse block (J/B)]
●
to BCM terminal 38.

ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input requesting the illumination lamps to illuminate. This input is communicated to the IPDM E/R across the
CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil which, when energized,
directs power
●
through IPDM E/R terminal 22
●
to illumination control switch terminal 1

BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is activated)
and the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the illumination lamps remain illuminated for 30 minutes unless the combination switch
(lighting switch) position is changed. If the combination switch (lighting switch) position is changed, then the
illumination lamps are turned off after a 30 second delay.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps have been turned off by the battery saver control, the illumination lamps illuminate again.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
ELS0014S
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

The underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these substances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate.

Be sure to perform engine maintenance when the engine is stopped.
NOTE:
On vehicles not equipped with A/C, there is an idler pulley in the position for the drive belt routing.
●
Remove the under cover using power tool, when inspecting the power steering pump belt.
●
Make sure that the stamp mark of the drive belt auto-tensioner is within the usable range.
NOTE:
● Check the drive belt auto-tensioner indicator (notch) when the engine is cold.
● When the new drive belt is installed, the range should be “A” as shown.
● Visually check the entire belt for wear, damage or cracks.
● If the indicator is out of allowable working range or belt is damaged, replace the belt. Refer to EM-15,
"Removal and Installation" .

WARNING:
●
To avoid being scalded, never change the coolant when the engine is hot.
●
Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn
to release built-up pressure. Then push down and turn the cap all the way to remove.
DRAINING ENGINE COOLANT

2.
When the inner and outer unbalance values are shown on the
wheel balancer indicator, multiply outer unbalance value by 1.6
to determine balance weight that should be used. Select the
outer balance weight with a value closest to the calculated
value, then install it at the designated outer position of, or at the
designated angle position on the road wheel.
Outer balance weight calculation:
Indicated unbalance value × 5/3 = outer balance weight
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) outer
balance weight (closer to calculated balance weight value)
SMA054D
NOTE:
The selected balance weight value must be the closest balance weight available to the calculated balance
weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)
CAUTION:
● Do not install the inner balance weight before installing the outer balance weight.
● Before installing the balance weight, be sure to clean the mating surface of the road wheel.

PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS00IYW
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Caution

ECS0093X
Do not reuse transaxle oil, properly dispose of it after it has been drained out.
Check the oil level or replace the oil only with the vehicle parked on level ground.
During removal or installation, keep inside of transaxle clear of dust or dirt.
Check for the correct installation status prior to removal or disassembly. If mating marks are required, be
certain they do not interfere with the function of the parts when applied.
In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, use it.
Be careful not to damage sliding surfaces and mating surfaces.

PRECAUTIONS
[RS6F51A]
PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
ECS00IYX
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along B
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front MT
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
D
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
E
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
F
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
G
Caution
●
●
●
●
●
●
ECS0094R
Do not reuse transaxle oil.
Drain, fill and check transaxle oil with the vehicle on level ground.
During removal and installation, keep inside of transaxle clean of dust and dirt.
Check for the correct installation orientation prior to removal or disassembly. If mating marks are required,
be certain they do not interfere with the function of the parts they are applied to.
In principle, tighten bolts or nuts gradually in several steps working diagonally and from inside to outside
as applicable. If a tightening sequence is specified, follow it.
Be careful not to damage the sliding surfaces and mating surfaces of parts.

When adjusting the reverse idler gear end play, select the
adjusting shim for the reverse idler gear. To select the correct
thickness of adjusting shim, measure the clearance between the
transaxle case and reverse idler gear.
Calculate the dimension “Q” (thickness of adjusting shim) using
the following steps to adjust the end play of the reverse idler
gear to specification.
End play
: 0.04 - 0.10 mm (0.0016 - 0.0039 in)
Dimension “Q” = (“Q1 ” - “Q2 ”) – End play

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS002RO
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Working with HFC-134a (R-134a)
EJS002RP
WARNING:
●
CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants
are mixed compressor failure is likely to occur. Refer MTC-4, "Contaminated Refrigerant" . To
determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refrigerant
Recovery/Recycling Recharging equipment and Refrigerant Identifier.
●
Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
If oil other than that specified is used, compressor failure is likely to occur.
●
The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:
–
When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
–
When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system.
–
Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without
proper sealing, oil will become moisture saturated and should not be used.
–
Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting
requirements of SAE J2210 [HFC-134a (R-134a) recycling equipment], or J2209 [HFC-134a (R-134a)
recycling equipment], If accidental system discharge occurs, ventilate work area before resuming
service. Additional health and safety information may be obtained from refrigerant and oil manufacturers.
–
Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.
Contaminated Refrigerant
EJS002RQ
If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are:
●
Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant
into the atmosphere.
●
Explain that recovery of the contaminated refrigerant could damage your service equipment and refrigerant supply.
●
Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
●
If you choose to perform the repair, recover the refrigerant using only dedicated equipment and containers. Do not recover contaminated refrigerant into your existing service equipment. If your facility
Revision: November 2006
MTC-4
2006 Altima
PRECAUTIONS
●
does not have dedicated recovery equipment, you may contact a local refrigerant product retailer for available service. This refrigerant must be disposed of in accordance with all federal and local regulations. In
addition, replacement of all refrigerant system components on the vehicle is recommended.
If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN
Customer Affairs for further assistance.
General Refrigerant Precautions
Precautions for Leak Detection Dye
●
●
●
●
●
●
●
●
B
EJS002RR
WARNING:
●
Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
●
Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
●
Do not store or heat refrigerant containers above 52°C (125°F).
●
Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
●
Do not intentionally drop, puncture, or incinerate refrigerant containers.
●
Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
●
Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
●
Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air conditioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refrigerant manufacturers.

EJS002RS
The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
I
(UV) lamp is required to illuminate the dye when inspecting for leaks.
Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
MTC
A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal
should only be repaired after confirming the leak with an electronic refrigerant leak detector (J-41995).
Always remove any dye from the leak area after repairs are complete to avoid a misdiagnosis during a K
future service.
Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled,
clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period
L
of time cannot be removed .
Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
Do not use more than one refrigerant dye bottle (1/4 ounce / 7.4 cc) per A/C system.
M
Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C systems or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C systems or A/C system damage may result.
The fluorescent properties of the dye will remain for over three (3) years unless a compressor failure
occurs.
A/C Identification Label
EJS002RT
Vehicles with factory installed fluorescent dye have this green identification label on the underside of hood.
Precautions for Refrigerant Connection
EJS002RU
A new type refrigerant connection has been introduced to all refrigerant lines except the following locations.
●
Expansion valve to cooling unit
●
Evaporator pipes to evaporator (inside cooling unit)
●
Refrigerant pressure sensor

PRECAUTIONS
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
●
●
The O-ring has been relocated. It has also been provided with a groove for proper installation. This eliminates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of
the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing
characteristics.
The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facilitating piping connections.

less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
G
●
When the compressor is removed, store it in the same position as it is when mounted on the car.
Failure to do so will cause oil to enter the low pressure chamber.
●
When connecting tubes, always use a torque wrench and a back-up wrench.
H
●
After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
●
When installing an air conditioner in the vehicle, connect the pipes as the final stage of the operation. Do not remove the seal caps of pipes and other components until just before required for
I
connection.
●
Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
MTC
●
Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
●
Always replace used O-rings.
●
When connecting tube, apply oil to circle of the O-rings shown in illustration. Be careful not to K
apply oil to threaded portion.

EJS002RV
Plug all openings to prevent moisture and foreign matter from entering.
When the compressor is removed, store it in the same position as it is when mounted on the car.
When replacing or repairing compressor, follow “Maintenance of Oil Quantity in Compressor”
exactly. Refer to MTC-19, "Maintenance of Oil Quantity in Compressor" .
Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with oil,
wipe it off by using a clean waste cloth moistened with thinner.
After compressor service operation, turn the compressor shaft by hand more than 5 turns in both
directions. This will equally distribute oil inside the compressor. After the compressor is installed,
let the engine idle and operate the compressor for 1 hour.
After replacing the compressor magnet clutch, apply voltage to the new one and check for normal
operation. [Gap between clutch disc and pulley is 0.3 - 0.6 mm (0.012 - 0.024 in)]
Precautions for Service Equipment

PRECAUTIONS
VACUUM PUMP
A
The oil contained inside the vacuum pump is not compatible with the
specified oil for HFC-134a (R-134a) A/C systems. The vent side of
the vacuum pump is exposed to atmospheric pressure so the vacuum pump oil may migrate out of the pump into the service hose.
This is possible when the pump is switched off after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve situated near the
hose-to-pump connection, as follows.
●
Usually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.
●
For pumps without an isolator, use a hose equipped with a manual shut-off valve near the pump end. Close the valve to isolate
the hose from the pump.
●
If the hose has an automatic shut off valve, disconnect the hose
from the pump: as long as the hose is connected, the valve is
open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under a no vacuum condition. Such valves may restrict the pump's
ability to pull a deep vacuum and are not recommended.

SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.

REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC134a (R-134a) and specified
oils have been used with the scale. If the scale controls refrigerant
flow electronically, the hose fitting must be 1/2”-16 ACME.
RHA274D
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder's top valve
when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.

REFRIGERATION SYSTEM
REFRIGERATION SYSTEM
Refrigerant Cycle
PFP:KA990
A
EJS002S1
REFRIGERANT FLOW
The refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank,
through the evaporator, and back to the compressor. The refrigerant evaporation through the evaporator coil is
controlled by an externally equalized expansion valve, located inside the evaporator case.
Refrigerant System Protection
EJS002S2
REFRIGERANT PRESSURE SENSOR
The refrigerant system is protected against excessively high or low pressures by the refrigerant pressure sensor, located on the condenser. If the system pressure rises above or falls below the specifications, the refrigerant pressure sensor detects the pressure inside the refrigerant line and sends the voltage signal to the ECM.
The ECM then signals the BCM (via CAN communication lines) to cease suppling power to the A/C relay
which disengages and stops the compressor. This occurs when pressure on the high pressure side (as
detected by refrigerant pressure sensor) is over approximately 2,746 kPa (28 kg/cm2 , 398 psi), or below
approximately 120 kPa (1.22 kg/cm2 , 17.4 psi).
PRESSURE RELIEF VALVE
B
C
D
E
F
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
When the refrigerant pressure in the system increases to an abnormal level [more than 3,727 kPa (38 kg/cm2
, 540 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into the
atmosphere.

AIR CONDITIONER CONTROL
Overview Air Conditioner LAN Control System
PFP:27500
EJS002S5
The LAN (local area network) system consists of front air control, air mix door motor, intake door motor, and
mode door motor.
A configuration of these components is shown in the diagram below.
WJIA0876E
System Construction
EJS002S6
A small network is constructed between the front air control, air mix door motor, intake door motor, and mode
door motor. The front air control and motors are connected by data transmission lines and motor power supply
lines. The LAN network is built through the ground circuits of the two motors.
Addresses, motor opening angle signals, motor stop signals and error checking messages are all transmitted
through the data transmission lines connecting the front air control and each motor.
The following functions are contained in LCUs built into the air mix door motor, intake door motor, and the
mode door motor.

OPERATION
The front air control receives signals from its various dials and switches. The front air control then sends air
mix door, mode door and intake door opening angle data to the air mix door motor LCU, mode door motor LCU
and intake door motor LCU.
The air mix door motor, mode door motor and intake door motor read their respective signals according to the
address signal. Opening angle indication signals received from the front air control and each of the motor position sensors are compared by the LCUs in each motor with the existing decision and opening angles. Subse-

WJIA0878E
TRANSMISSION DATA AND TRANSMISSION ORDER
E
Front air control data is transmitted consecutively to each of the door motors following the form shown in figure
below.
Start: Initial compulsory signal sent to each of the door motors.
Address: Data sent from the front air control is selected according to data-based decisions made by the air mix F
door motor, mode door motor and intake door motor.
If the addresses are identical, the opening angle data and error check signals are received by the door motor
LCUs. The LCUs then make the appropriate error decision. If the opening angle data is normal, door control G
begins.
If an error exists, the received data is rejected and corrected data received. Finally, door control is based upon
the corrected opening angle data.
H
Opening angle: Data that shows the indicated door opening angle of each door motor.
Error check: Procedure by which sent and received data is checked for errors. Error data is then compiled.
The error check prevents corrupted data from being used by the air mix door motor, mode door motor and
intake door motor. Error data can be related to the following problems.

●
Abnormal electrical frequency
●
Poor electrical connections

A
Mode door control system components are:
●
Front air control
●
Mode door motor (LCU)
B
System Operation
The front air control receives signals from its various dials and switches. The front air control then sends air
mix door, mode door and intake door motor opening angle data to the air mix door motor LCU, mode door
motor LCU and intake door motor LCU.
The mode door motor reads their respective signals according to the address signal. Opening angle indication
signals received from the front air control and each of the motor position sensors are compared by the LCU's
in each motor with the existing decision and opening angles. Subsequently, HOT/COLD or DEFROST/VENT
or FRESH/RECIRCULATION operation is selected. The new selection data is returned to the front air control.

Checking for Refrigerant Leaks
A
EJS002TH
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leakage, damage and corrosion. A/C oil leakage may indicate an area of refrigerant leakage. Allow extra inspection time in these areas when using either an electronic refrigerant leak detector or fluorescent dye leak
detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 25 - 50 mm (1 - 2 in) per second and no further than 6 mm (1/4 in) from the component.
CAUTION:
Moving the electronic leak detector probe slower and closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak Detector
EJS002TI

C
D
E
F
1.
Check A/C system for leaks using the UV lamp and safety goggles (J-42220) in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indi- G
cates an evaporator core assembly (tubes, core or TXV) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
H
3. After the leak is repaired, remove any residual dye using refrigerant dye cleaner (J-43872) to prevent
future misdiagnosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
I
leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and oils, may falsely trigger the leak detector. Make sure the surfaces to be checked are MTC
clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings K
and may damage the detector.

5.
6.
7.
Check the A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.52 kg/cm2 , 50 psi).
Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (J-41459).
CAUTION:
If repairing the A/C system or replacing a component, pour the dye directly into the open system
connection and proceed with the service procedures.
Connect the injector tool to the A/C LOW PRESSURE side service valve.
Start the engine and switch the A/C ON and fan ON.
While the A/C is operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye
through the low-pressure service valve using dye injector tool (J-41459), refer to the manufacturer's operating instructions.
With the engine still running, disconnect the injector tool from the low-pressure service valve.
Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leak size, operating conditions and location of the leak, it may take from a few minutes to a few days for
the dye to penetrate the leak and become visible.

PRECAUTIONS FOR HANDLING THE LEAK DETECTOR
When performing a refrigerant leak check, use a electronic refrigerant leak detector (J-41995) or equivalent. Ensure that the instrument
is calibrated and set properly per the manufacturer's operating
instructions.
The leak detector is a delicate device. In order to use the leak detector properly, read the manufacturer's operating instructions and perform any specified maintenance.
AHA281A
1.
Position the leak detector probe approximately 5 mm (3/16 in)
away from the point to be checked.
SHA707EA
2.
When testing, circle each fitting completely with the leak detector probe.
SHA706E
3.
Move the leak detector probe along the component at approximately 25 to 50 mm (1 to 2 in)/sec.
SHA708EA
CHECKING PROCEDURE
NOTE:
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in a calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Turn engine OFF.
2. Connect a suitable A/C manifold gauge set to the A/C service ports.
Revision: November 2006
MTC-102
2006 Altima
REFRIGERANT LINES
Check if the A/C refrigerant pressure is at least 345 kPa (3.52 kg/cm2 , 50 psi) above 16°C (61°F). If less
A
than specification, recover/evacuate and recharge the system with the specified amount of refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected since the system may not reach 345 kPa
B
(3.52 kg/cm2 , 50 psi) pressure.
4. Conduct the leak test from the high side (compressor discharge to evaporator inlet) to the low side (evaporator drain hose to the compressor shaft seal). Refer to MTC-90, "Components" . Clean the component
C
to be checked and move the leak detector probe completely around the connection/component.
Perform a leak check for the following areas:
● Compressor
D
● High and low-pressure hose fittings, relief valve and shaft seal.
● Liquid tank
● Refrigerant pressure sensor
E
● Service valves
– Check that all the service valve caps are secure on the service valves (to prevent leaks).
– After removing A/C manifold gauge set from service valves, wipe any residue from the valves to preF
vent any false readings by the leak detector.
● Evaporator
– With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace
G
around the evaporator. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer's
recommended procedure for actual wait time) before inserting the leak detector probe into the drain
hose.
H
– Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with
water or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
I
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7 - 10.
MTC
7. Start engine.
8. Set the front air control as follows;
a. A/C switch: ON
K
b. Mode: Vent
c. Intake position: Recirculation
d. Temperature: MAX cold
L
e. Blower fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps 4
M
through 6 above.
Refrigerant leaks should be checked immediately after stopping
the engine. Begin with the leak detector at the compressor. The
pressure on the high pressure side will gradually drop after
refrigerant circulation stops and pressure on the low pressure
side will gradually rise, as shown in the graph. Some leaks are
more easily detected when pressure is high.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EFS0067X
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System Description
EKS008UE
IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block
which were originally placed in engine compartment. It controls integrated relays via IPDM E/R control circuits.
●
IPDM E/R-integrated control circuits perform ON-OFF operation of relays, CAN communication control, oil
pressure switch signal reception, etc.
●
It controls operation of each electrical component via BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R-integrated relays can be individually removed.
●
SYSTEMS CONTROLLED BY IPDM E/R
1. Lamp control
Using CAN communication lines, it receives signals from the BCM and controls the following lamps:
●
Headlamps (Hi, Lo)
●
Parking lamps
●
Tail lamps
●
Front fog lamps
2. Wiper control
Using CAN communication lines, it receives signals from the BCM and controls the front wipers.
3. Rear window defogger relay control
Using CAN communication lines, it receives signals from the BCM and controls the rear window defogger
relay.
4. A/C compressor control
Using CAN communication lines, it receives signals from the ECM and controls the A/C compressor magnetic
clutch).
5. Cooling fan control
Using CAN communication lines, it receives signals from the ECM and controls the cooling fan relays.
6. Horn control
Using CAN communication lines, it receives signals from the BCM and controls the horn relay.
CAN COMMUNICATION LINE CONTROL
With CAN communication, by connecting each control unit using two communication lines (CAN L-line, CAN
H-line), it is possible to transmit maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and read necessary information only.
1. Fail-safe control
● When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
After CAN communication recovers normally, it also returns to normal control.
● Operation of control parts by IPDM E/R during fail-safe mode is as follows:
Controlled system
Headlamp
Tail and parking lamps
Cooling fan
Fail-safe mode
●
With the ignition switch ON, the headlamp (low) is ON.
●
With the ignition switch OFF, the headlamp (low) is OFF.
●
With the ignition switch ON, the tail and parking lamps are ON.
●
With the ignition switch OFF, the tail and parking lamps are OFF.
●
With the ignition switch ON, the cooling fan HI operates.
●
With the ignition switch OFF, the cooling fan stops.
Front wiper
Until the ignition switch is turned off, the front wiper LO and HI remains in the same status it
was in just before fail−safe control was initiated.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition.
1. CAN communication status
● CAN communication is normally performed with other control units.
● Individual unit control by IPDM E/R is normally performed.
● When sleep request signal is received from BCM, mode is switched to sleep waiting status.
2. Sleep waiting status
● Process to stop CAN communication is activated.
● All systems controlled by IPDM E/R are stopped. When 1 second has elapsed after CAN communication with other control units is stopped, mode switches to sleep status.
3. Sleep status
● IPDM E/R operates in low current-consumption mode.
● CAN communication is stopped.
● When a change in CAN communication signal is detected, mode switches to CAN communication status.
● When a change in ignition switch signal is detected, mode switches to CAN communication status.

3.
4.
5.
6.
Close hood and front door RH, and lift wiper arms away from windshield (to prevent glass damage by
wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
Turn ignition switch OFF.
Turn ignition switch ON and, within 20 seconds, press front door switch LH 10 times. Then turn ignition
switch OFF.
Turn ignition switch ON within 10 seconds after ignition switch OFF.
When auto active test mode is actuated, horn chirps once.
After a series of operations is repeated three times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Be sure to perform BL-31, "Door Switch Check" when the auto active test cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE

Concept of Auto Active Test
IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN communication line. Therefore, when auto active test mode is activated successfully, CAN communication
between IPDM E/R and BCM is normal.
●
If any of systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EGS000QL
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

EGS000QM
Before disassembly, thoroughly clean the outside of the unit.
Disassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
For easier and proper assembly, place disassembled parts in order on a parts rack.
Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
Before inspection or reassembly, carefully clean all parts with a general purpose, non-flammable
solvent.
Before assembly, apply a coat of recommended Genuine NISSAN PSF or equivalent to hydraulic
parts. Petroleum jelly may be applied to O-rings and seals. Do not use any grease.
Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during installation. Perform functional tests whenever designated.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EDS0047F
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS00BEZ
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions
EIS003LO
Disconnect both battery cables in advance.
●
Never tamper with or force air bag lid open, as this may adversely affect air bag performance.
●
Be careful not to scratch pad and other parts.
●
When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
●
When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
●
Keep removed parts protected with cloth.
●
If a clip is deformed or damaged, replace it.
●
If an unreusable part is removed, replace it with a new one.
●
Tighten bolts and nuts firmly to the specified torque.
●
After re-assembly has been completed, make sure each part functions correctly.
●
Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.
●
Do not use any organic solvent, such as thinner or benzine.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer comments; refer to RF-8, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
●
The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
●
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.
●
After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
●
Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions. Hard surfaces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
●
Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
●
Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
●
Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
●
Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
●
Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
●
Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
●
Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be irritating to the customer.
●
Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle "twist".
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
●
Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
●
If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.

CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.

●
●
●
●
G
Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear: J-39565 and mechanic's stethoscope).
Narrow down the noise to a more specific area and identify the cause of the noise by:
H
removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken
or lost during the repair, resulting in the creation of new noise.
RF
tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.
feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the J
noise.
placing a piece of paper between components that you suspect are causing the noise.
K
looking for loose components and contact marks.
Refer to RF-6, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
If the cause is a loose component, tighten the component securely.
●
If the cause is insufficient clearance between components:
–
separate components by repositioning or loosening and retightening the component, if possible.
–
insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape are available through your authorized Nissan Parts Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
Each item can be ordered separately as needed.

FELT CLOTH TAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15×25 mm (0.59×0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll.
The following materials, not found in the kit, can also be used to repair squeaks and rattles.
UHMW (TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit.
Note: Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle Troubleshooting
EIS0048D
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise.
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
Revision: November 2006
RF-6
2006 Altima
SQUEAK AND RATTLE TROUBLE DIAGNOSES
In addition look for:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.

F
G
H
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the RF
noise.
Cause of seat noise include:
1. Headrest rods and holder
J
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con- K
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
L
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EES0024S
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions
●
●
●
●
●
EES0017F
When installing each rubber part, final tightening must be carried out under unladen condition*
with tires on ground.
Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
* Fuel, engine coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
After installing removed suspension parts, check wheel alignment.
Do not jack up at the radius rod, front and rear lower links.
Lock nuts are not reusable parts, always use new ones.
When installing, do not wipe the oil off of the new lock nut before tightening.

THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-13, "Rear A
Wheel Alignment (Unladen*)" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
B
minus, Go/No Go). Do NOT use these indicators.
● The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.
C
● This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “compensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
D
● Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
● See Instructions in the alignment machine you are using for more information.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EHS000ZV
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precaution for Seat Belt Service
EHS000ZW
CAUTION:
●
Before removing the seat belt pre-tensioner assembly, turn the ignition switch off, disconnect the
battery ground cable and wait at least 3 minutes.
●
Do not use electrical test equipment for seat belt pre-tensioner connector.
●
After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-tensioner connector, check the system function. Refer to SRS-20, "SRS Operation Check" .
●
Do not use disassembled buckle or seat belt assembly.
●
Replace anchor bolts if they are deformed or worn out.
●
Never oil tongue and buckle.
●
If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.
●
If webbing is cut, frayed, or damaged, replace seat belt assembly.
●
When replacing seat belt assembly, use a genuine NISSAN seat belt assembly.

NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the collision was minor and the belts show no damage and continue to operate properly. Failure to do so
could result in serious personal injury in an accident. Seat belt assemblies not in use during a collision should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioner
should be replaced even if the seat belts are not in use during a frontal collision in which the air bags
are deployed.
Replace any seat belt assembly (including anchor bolts) if:
●
The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).
●
The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide).
●
The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.
●
Anchor bolts are deformed or worn out.
●
The seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in

AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the collision was minor and the belts show no damage and continue to operate properly. Failure to do so
could result in serious personal injury in an accident. Seat belt assemblies not in use during a collision should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioners
should be replaced even if the seat belts are not in use during a frontal collision in which the air bags
are deployed.
Replace any seat belt assembly (including anchor bolts) if:
●
The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).
●
The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide).
●
The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.

Check the seat belt warning lamp/chime for proper operation as follows:
Switch ignition ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime should
sound for about seven seconds.
Fasten driver's seat belt. The seat belt warning lamp should go out and the chime (if sounding) should
stop.
If the air bag warning lamp is blinking, conduct self-diagnosis using CONSULT-II, and air bag warning
lamp. Refer to SRS-20, "SRS Operation Check" .
Check that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Ensure guide swivels
freely and that belt lays flat and does not bind in guide. Ensure height adjuster operates properly and
holds securely.
Check retractor operation:
Fully extend the seat belt webbing and check for twists, tears or other damage.
Allow the seat belt to retract. Ensure that belt returns smoothly and completely into the retractor. If the
seat belt does not return smoothly, wipe the inside of the loops with a clean paper cloth, because dirt built
up in the loops of the upper anchors can cause the seat belts to retract slowly.
Fasten the seat belt. Check the seat belt returns smoothly and completely to the retractor. If the belt does
not return smoothly, the cause may be an accumulation of dust or dirt. Use the “SEAT BELT TAPE SET”
and perform the following steps.
Inspect the front seat belt though-anchor:
1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
2. Use a clip or other device to hold the seat belt at the center pillar belt opening.
3. Pass a thin wire through the through-anchor belt opening. Hold both ends of the wire and pull taut while
moving it up and down several times along the belt opening surface to remove dirt.
4. Any dirt that cannot be removed with the wire can be removed by cleaning the opening with a clean
cloth.
5. Apply tape at the point where the belt contacts the though-anchor belt opening.
NOTE:
Apply the tape so that there is no looseness or wrinkling.
6. Remove the clip holding the seat belt and check that the belt returns smoothly.
7. Repeat steps above as necessary to check the other seat belts.

NOTE:
All seat belt retractors are of the Emergency Locking Retractors (ELR) type. In an emergency (sudden stop)
the retractor will lock and prevent the belt from extending any further. All 3-point type seat belt retractors
except the driver's seat belt also have an Automatic Locking Retractors (ALR) mode. The ALR mode (also
called child restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt
is fully extended. When the belt is then retracted partially, the ALR mode automatically locks the seat belt in a
specific position so the belt cannot be extended any further. To cancel the ALR mode, allow the seat belt to
fully wind back into the retractor.
Check the seat belt retractors using the following test(s) to determine if a retractor assembly is operating properly.

wet or gravel roads or on public streets and highways. This could result in an accident and serious
personal injury. The driver and passenger must be prepared to brace themselves in the event the
retractor does not lock.
1. Fasten driver's seat belt. Buckle a passenger into the seat for the belt that is to be tested.
2. Proceed to the designated safe area.
3. Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of a pending sudden stop.
The driver and passenger must be prepared to brace themselves in the event the retractor does not lock.
Apply brakes firmly and make a very hard stop.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS008KU
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

CAUTION:
●
If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
●
After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
●
Never add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging
a battery.
●
The battery surface (particularly its top) should always be kept
clean and dry.
●
The terminal connections should be clean and tight.
●
At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance”
and “maintenance-free”.
MEL040F
●
When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
MEL041F
●
Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
MEL042F
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touching a battery, do not touch or rub your eyes until you have thoroughly washed your hands. If acid contacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less current and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into service by means of a long, slow charge, 12 hours or more, followed by a battery capacity test.

CHARGING SYSTEM
CHARGING SYSTEM
System Description
PFP:23100
EKS008L6
The generator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to generator terminal B through:
●
120A fusible link (letter a , located in the fusible link box).
Power is supplied at all times to generator terminal S through:
●
10A fuse (No. 26, located in the fuse and fusible link box).
Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal S detecting the input voltage. The charging circuit is protected by the
120A fusible link.
The generator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied:
●
through 10A fuse [No. 14, located in the fuse block (J/B)]
●
to combination meter terminal 22 for the charge warning lamp.
Ground is supplied to terminal 14 of the combination meter through terminal L of the generator. With power
and ground supplied, the charge warning lamp will illuminate. When the generator is providing sufficient voltage with the engine running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a fault is indicated.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS003N9
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to SE-8, "Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.
●
The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
●
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.
●
After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
●
Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
●
Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
●
Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
●
Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
●
Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.
●
Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.
●
Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
●
Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.
●
Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to duplicate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
●
Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
●
If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.

CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
F
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE

●
●
●
●
●
G
Narrow down the noise to a general area.To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear: J-39565 and mechanic's stethoscope).
Narrow down the noise to a more specific area and identify the cause of the noise by:
H
removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be broken or lost during the repair, resulting in the creation of new noise.
SE
tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.
feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the J
noise.
placing a piece of paper between components that you suspect are causing the noise.
K
looking for loose components and contact marks.
Refer to SE-6, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
If the cause is a loose component, tighten the component securely.
●
If the cause is insufficient clearance between components:
–
separate components by repositioning or loosening and retightening the component, if possible.
–
insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through your authorized NISSAN
Parts Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISSAN Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle Troubleshooting
EIS00481
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the NISSAN Squeak and Rattle Kit (J-43980) to repair the noise.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid bumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise.
SUNROOF/HEADLINING
A
B
C
D
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
E
F
OVERHEAD CONSOLE (FRONT AND REAR)
Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of
these incidents are repaired by pushing up on the console at the clip locations until the clips engage.
In addition look for:
1. Loose harness or harness connectors.
2. Front console map/reading lamp lense loose.
3. Loose screws at console attachment points.
SEATS
G
H
SE
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
J
K
L
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EHS00102
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

●
●
●
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
SRS
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
I
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
The air bag diagnosis sensor unit must always be installed with the arrow mark “⇐” pointing toward the
front of the vehicle for proper operation. Also check air bag diagnosis sensor unit for cracks, deformities or J
rust before installation and replace as required.
The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
K
turn steering wheel or column after removal of steering gear.
Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and seat mounted front side air bag module standing with the stud bolt side facing
L
down.
Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
After air bag inflates, the front instrument panel assembly should be replaced if damaged.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Front Seat Belt Pre-tensioner with Load Limiter
The seat belt pre-tensioner system with load limiter is installed for
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag system in the event of a frontal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are thrown forward in a collision and
the restraining force of the seat belt exceeds a specified level, the
load limiter permits the specified extension of the seat belt by the
twisting of the ELR shaft, and a relaxation of the chest-area seat belt
web tension while maintaining force.

Occupant Classification System (OCS)
EHS001MI
The occupant classification system (OCS) identifies different size occupants, out of position occupants, and
detects if child seat is present in the front passenger seat. The OCS receives inputs from the occupant classification sensor (located inside the passenger seat cushion assembly) and belt tension sensor (part of the passenger front seat belt assembly and located at the belt anchor location). Depending on classification of the
passenger, the OCS sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis sensor unit
uses this signal and the seat belt buckle switch RH signal to determine deployment or non deployment of the
passenger front air bag in the event of a collision. Depending on the signals received, the air bag diagnosis
sensor unit can disable the passenger front air bag completely.
NOTE:
In case of customer concern, CONSULT-II can be used to confirm the passenger air bag status (readiness).

TROUBLE DIAGNOSIS
CONSULT-II Function (AIR BAG)
EHS0013H
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
AIR BAG diagnostic mode
Description
SELF-DIAG [CURRENT]
A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring repairs.
SELF-DIAG [PAST]
TROUBLE DIAG RECORD
ECU DISCRIMINATED NO.
PASSENGER AIR BAG
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The
stored results will remain until memory erasing is executed.
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed on the CONSULT-II screen.
The air bag diagnosis sensor unit for each vehicle
model is assigned with its own, individual classification number. This number will be displayed on
the CONSULT-II screen, as shown. When replacing the air bag diagnosis sensor unit, refer to the
part number for the compatibility. After installation,
replacement with a correct unit can be checked by
confirming this classification number on the CONSULT-II screen.
The air bag diagnosis sensor unit discriminated numbers assigned are F637 (for models
without side air bags) and F638 (for models
with side air bags).
ARS366
The STATUS (readiness) of the front passenger air
bag module is displayed. The STATUS displayed
(ON/OFF) depends on the signals supplied to the
occupant classification system control module and
air bag diagnosis sensor unit. Refer to SRS-6,
"Occupant Classification System (OCS)" for more
information.

Wiring Harness Modification
The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.
Service replacement passenger air bag modules use tab-locking style harness connectors. If the passenger
air bag module is replaced, or if the direct-connect harness connectors are damaged, the vehicle wiring harness must be modified to allow connection of the service replacement passenger air bag module.
NOTE:
The wiring harness modification is to be performed only if the vehicle is equipped with the original passenger
air bag which uses direct-connect harness connectors. If the passenger air bag is to be replaced in a vehicle
that has already had the service replacement passenger air bag installed, the wiring harness modification is
not required.

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting, WT
select and adjust a drive-in weight mode suitable for wheels.
Set wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
F
When inner and outer unbalance values are shown on the wheel
balancer indicator, multiply outer unbalance value by 1.6 to
determine balance weight that should be used. Select the outer
balance weight with a value closest to the calculated value and
G
install it to the designated outer position of, or at the designated
angle in relation to the road wheel.
CAUTION:

mating surface of the wheel.
Indicated unbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz.) × 5/3 = 38.33 g (1.35 oz.) = 40 g (1.41 oz.) balance weight (closer to calculated balance J
weight value)
Note that balance weight value must be closer to the calculated balance weight value.

PRECAUTION
PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
EKS008QF
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
●
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.
●
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

LOW SPEED WIPER OPERATION
When the ignition switch is in the ON or START position and the front wiper switch is turned to low position,
the BCM detects a low speed wiper ON signal by BCM wiper switch reading function.
BCM then sends front wiper (low) request signal over CAN communication lines
●
from BCM terminals 39 and 40
●
to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper (low) request signal, it supplies ground to energize the front wiper relay.
With the front wiper relay energized, power is supplied
●
through front wiper relay
●
to front wiper HI relay
●
through IPDM E/R terminal 21
●
to front wiper motor terminal L.
With power and ground supplied, the front wiper motor operates at low speed.
HI SPEED WIPER OPERATION
I
J
WW
L
When the ignition switch is in the ON or START position and the front wiper switch is turned to high position,
the BCM detects a high speed wiper ON signal by BCM wiper switch reading function.
BCM then sends front wiper (high) request signal over CAN communication lines
●
from BCM terminals 39 and 40
●
to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper (high) request signal, it supplies ground to energize the front wiper and
the front wiper HI relays.
With the front wiper and the front wiper HI relays energized, power is supplied
●
through front wiper relay
●
to front wiper HI relay
●
through IPDM E/R terminal 31
●
to front wiper motor terminal H.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Wiper intermittent operation delay interval is determined from the combination of the intermittent wiper dial
position inputs and vehicle speed. During each intermittent operation delay interval, the BCM sends a front
wiper request signal to the IPDM E/R to operate the wipers.
Revision: November 2006

WW-5
2006 Altima

FRONT WIPER AND WASHER SYSTEM
When the ignition switch is in ON or START position and the front wiper switch is turned to intermittent position, the BCM detects a front wiper (intermittent) ON signal by BCM wiper switch reading function.
BCM then sends front wiper (intermittent) request signal over CAN communication lines
●
from BCM terminals 39 and 40
●
to IPDM E/R terminals 48 and 49.
When BCM determines that combination switch status is front wiper intermittent ON, it performs the following
operations.
●
BCM detects ON/OFF status of intermittent wiper dial position
●
BCM calculates operation interval from wiper dial position and vehicle speed signal received through CAN
communications
●
BCM sends front wiper request signal (INT) to IPDM E/R at calculated operation interval.
When IPDM E/R receives front wiper request signal (INT), it supplies ground to energize the front wiper relay.
It then sends auto-stop signal to BCM and conducts intermittent front wiper motor operation.
AUTO STOP OPERATION
When the wiper arms are not located at the base of the windshield and the wiper switch is turned OFF, the
wiper motor will continue to operate until the wiper arms reach windshield base. When wiper arms reach base
of windshield, front wiper motor terminals E and P are connected.
Ground is supplied
●
to IPDM E/R terminal 32
●
through front wiper motor terminal P
●
through front wiper motor terminal E
●
through grounds E15 and E24.
The IPDM E/R sends auto stop operation signal to BCM through CAN communication lines.
When BCM receives auto stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN communication lines. The IPDM E/R then de-energizes the front wiper relay.
Wiper motor will then stop wiper arms at the STOP position.
WASHER OPERATION
When wiper switch is in front wiper washer position, BCM detects front wiper washer signal by BCM wiper
switch reading function. Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
When the ignition switch is in ON or START position, power is supplied
●
through 10A fuse (No. 47, located in the IPDM E/R)
●
through IPDM E/R terminal 44
●
to front washer motor terminal 1.
When front wiper switch is turned to washer position, ground is supplied
●
to front washer motor terminal 2
●
through combination switch terminal 3
●
through combination switch terminal 9
●
through grounds F14, M57 and M61.
With ground supplied, the front washer motor is operated.
When BCM detects that front washer motor has operated for 0.4 seconds or longer, BCM uses CAN communication and sends wiper request signal to IPDM E/R for low speed operation of wipers.
When BCM detects that washer switch is OFF, low speed operation cycles approximately 3 times and then
stops.
MIST OPERATION
When the wiper switch is temporarily placed in the mist position, wiper low speed operation cycles once and
then stops.
For additional information about wiper operation under this condition, refer to WW-5, "LOW SPEED WIPER
OPERATION" .
If the switch is held in the mist position, low speed operation continues.
FAIL-SAFE FUNCTION
BCM includes fail-safe function to prevent malfunction of electrical components controlled by CAN communications if a malfunction in CAN communications occurs.
Revision: November 2006
WW-6
2006 Altima
FRONT WIPER AND WASHER SYSTEM
BCM uses CAN communications to stop output of electrical components it controls.
Until ignition switch is turned off, front wiper remains in same status as just before fail-safe control was initiated. (If wiper was in low speed operation just before fail-safe, it continues low speed operation until ignition
switch is turned OFF.)
When fail-safe status is initiated, BCM remains in standby until normal signals are received.
When normal signals are received, fail-safe status is canceled.

FRONT WIPERS OPERATE FOR 10 SECONDS, STOP FOR 20 SECONDS, AND AFTER
REPEATING THIS OPERATION FIVE TIMES, THEY BECOME INOPERATIVE
CAUTION:
●
When auto stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers front wipers locked and stops wiper output, which causes this symptom.
●
This status can be checked by using IPDM E/R "DATA MONITOR". Under this condition, "WIP
PROT" reads "BLOCK".
