Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BCS000N8
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.
Precautions Necessary for Steering Wheel Rotation After Battery Disconnect
BCS000N9
NOTE:
●
This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).
●
Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
●
Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1.
2.
3.
4.
5.
6.
Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
Perform the necessary repair operation.
When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
Perform a self-diagnosis check of all control units using CONSULT-II.
AT-10
PRECAUTIONS
Precautions for On Board Diagnostic (OBD) System of A/T and Engine (For
EURO-OBD models Only)
BCS000NA
A
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.
B
CAUTION:
●
Be sure to turn the ignition switch OFF and disconnect battery negative cable from battery negative terminal before any repair or inspection work. The open/short circuit of related switches, senAT
sors, 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 connectors are free from water,
grease, dirt, bent terminals, etc.)
D
●
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 erase the unnecessary malfunction information (repairs completed) from the TCM and E
ECM before returning the vehicle to the customer.
Precautions
●
BCS000NB
F
Before connecting or disconnecting the TCM harness connector, turn ignition switch OFF and disconnect the battery
cable from the negative terminal. Failure to do so may damage the TCM. Because battery voltage is applied to TCM
even if ignition switch is turned off.
G
H
I
SEF289H
●
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.
J
K
L
AAT470A
●
●
●
●
●
●
Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. (See page AT-80, "TCM Terminals and Reference
Value".)
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
MEF040DA
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 shop rags can leave fibers that could interfere
with the operation of the A/T.
Place disassembled parts in order for easier and proper assembly.
AT-11
M
PRECAUTIONS
●
●
●
●
●
●
●
●
●
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 A/T 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 A/T 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-19, "Changing A/T Fluid" , AT-18, "Checking A/T Fluid" .
Service Notice or Precautions

clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.
AT-12
PRECAUTIONS
OBD SELF-DIAGNOSIS (FOR EURO-OBD MODELS ONLY)
A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through A
the blinking pattern of the OD OFF indicator lamp or the malfunction indicator lamp (MIL). Refer to the
table on AT-95, "Judgement of Self-diagnosis Code" for the indicator used to display each self-diagnostic
result.
B
●
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-99, "HOW TO ERASE DTC" to com- AT
plete 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

Line Pressure Control
●
●
●
BCS000NM
TCM has various line pressure control characteristics to match 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 characteristic of the line pressure to the throttle opening 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 or D3,
great driving force is applied to the clutch inside the transaxle. 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.
SCIA4828E
AT-32
A/T CONTROL SYSTEM
AT LOW FLUID TEMPERATURE
●
●
A/T fluid viscosity and frictional characteristics of the clutch facing change with A/T fluid temperature.
Clutch engaging or band-contacting pressure is compensated for, according to A/T fluid temperature, to
stabilize shifting quality.
The line pressure is reduced below 60°C (140°F) to prevent
shifting shock due to high viscosity of A/T fluid when temperature is low.
A
B
AT
D
SCIA4829E
●
Line pressure is increased to a maximum irrespective of the
throttle opening when A/T fluid temperature drops to −10°C
(14°F). This pressure rise is adopted to prevent a delay in clutch
and brake operation due to extreme drop of A/T fluid viscosity at
low temperature.

SCIA4830E
Shift Control
BCS000NN
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 (accelerator
pedal position sensor). This results in improved acceleration performance and fuel economy.
I
J
CONTROL OF SHIFT SOLENOID VALVES A AND B
The TCM activates shift solenoid valves A and B according to signals from the accelerator pedal position sensor and revolution sensor to select the optimum gear position on the basis of the shift
schedule memorized in the TCM.
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.

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 figure 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
BCS000NO
The torque converter clutch piston in the torque converter is locked to eliminate torque converter slip and 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 torque converter clutch piston.
CONDITIONS FOR LOCK-UP OPERATION
When vehicle is driven in 3rd and 4th gear positions, 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.

A/T CONTROL SYSTEM
Lock-up Released
In the lock-up released state, the torque converter clutch control valve is set into the unlocked state by draining the torque converter clutch piston applying pressure and the torque converter clutch piston release pressure is generated.
In this way, the torque converter clutch piston is not coupled.
A
B
Lock-up Applied
In the lock-up applied state, the torque converter clutch control valve is set into the locked state by generating
the torque converter clutch piston applying pressure and the torque converter clutch piston release pressure is AT
drained.
In this way, the torque converter clutch piston is pressed and coupled.
D
SMOOTH LOCK-UP CONTROL
When shifting from the lock-up released state to the lock-up applied state, the current output to the torque converter clutch solenoid 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.
E
Half-clutched State
The current output from the TCM to the torque converter clutch solenoid is varied to steadily increase the
torque converter clutch solenoid pressure.
In this way, the lock-up applying pressure gradually rises and while the torque converter clutch piston is put
into half-clutched status, the torque converter clutch piston applying pressure is increased and the coupling is
completed smoothly.
Engine Brake Control (Overrun Clutch Control)
F
G
BCS000NP
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.

AT-35
A/T CONTROL SYSTEM
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. Only in “1” position, however, 1 range pressure is
applied to overrun clutch control valve, resulting in valve moving
downward and clutch engaged.
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. At overrun clutch reducing valve in “D” position, the hydraulic pressure is reduced to a level
that balances the spring force. This is sent to overrun clutch control
valve and becomes the operating pressure of overrun clutch which is
engaged at all times. In “2” position and “1” position, overrun clutch
reducing valve is pushed down by 2 range pressure. Line pressure is
directly sent to overrun clutch control valve and becomes the operating pressure of overrun clutch which is engaged at all times.

Centrifugal Cancel Mechanism
BCS000NR
FUNCTION
The centrifugal cancel mechanism is a mechanism to cancel the centrifugal hydraulic pressure instead of the
conventional check balls. It cancels the centrifugal hydraulic pressure which is generated as high clutch drum
rotates, and it allows for preventing high clutch from dragging and for providing stable high clutch piston pressing force in all revolution speeds.
STRUCTURE/OPERATION
A centrifugal cancel housing is provided to cancel the clutch housing pressure. The centrifugal cancel housing
is always filled with ATF from the dedicated fluid passage of oil pump.
SCIA6832E
When Clutch Pressure Is Not Applied
As high clutch drum rotates, a centrifugal force applies to the remaining ATF in clutch housing to push high
clutch piston. However, on the other hand, the centrifugal force also applies to ATF filled in centrifugal cancel
housing, resulting in a force that pushes high clutch piston back. Consequently the high clutch piston does not
move because both forces cancel each other, and thus high clutch is prevented from dragging.
When Clutch Pressure Is Applied
Clutch pressure that applies to clutch housing overcomes the fluid pressure and spring force of the opposing
centrifugal housing to push high clutch piston, and high clutch is engaged. At this time, the centrifugal force
caused by the revolution speed of high clutch drum has no impact any more since the centrifugal force that
applies to the clutch pressure of clutch housing is canceled by the centrifugal force that applies to centrifugal
cancel housing. As a result, high clutch piston pressing force is always stable in all revolution speeds, and
thus smooth shifting characteristics are achieved.

Fail-safe
BCS000NV
The TCM has an electronic Fail-safe 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.
Always follow the “AT-43, "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.
FAIL-SAFE FUNCTION
The following fail-safe functions allow vehicles to be driven even when sensor, switch or solenoid malfunction
occurs.
Vehicle Speed Sensor·A/T (Revolution Sensor)
Vehicle speed sensor·MTR signal is input from combination meter.
Accelerator Pedal Position Sensor Signal and Throttle Position Sensor Signal
TCM controls the throttle opening angle to a predetermined fixed position to enable driving if a malfunctioning

PNP Switch
When the multiple PNP switch signals are input to TCM, the priority of selector lever position becomes “D”,
“N”, “R”, “2” and “1” in order by internal TCM determination.
The use of 4th gear is inhibited until normal operation resumes. Because the hydraulic circuit of the control

TROUBLE DIAGNOSIS
How to Perform Trouble Diagnoses for Quick and Accurate Repair
BCS000NW
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, accelerator pedal position sensor or PNP switch and provides shift control or
lock-up control via A/T solenoid valves.
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.
It is much more difficult to diagnose a malfunction that occurs intermittently rather than continuously. Most intermittent malfunctions 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 malfunctions. A
road test with CONSULT-II or a circuit tester connected should be
performed. Follow the AT-43, "WORK FLOW" .
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 malfunctions, especially intermittent ones. Find out what symptoms are present and
under what conditions they occur. A “DIAGNOSTIC WORKSHEET”
like the example (AT-45, "DIAGNOSTIC WORKSHEET" ) should be
used.
Start your diagnosis by looking for “conventional” malfunctions first.
This will help troubleshoot driveability malfunctions on an electronically controlled engine vehicle.
Also check related Service bulletins for information.

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).

ON BOARD DIAGNOSTIC (OBD) SYSTEM
[EURO-OBD]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
Introduction
[EURO-OBD]
PFP:00028
BCS000OC
A/T system has two self-diagnostic systems.
The first is emission-related on board diagnostic system (OBD) performed by the TCM 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 OD OFF indicator lamp. The malfunction is
stored in the TCM memory. The detected items are overlapped with OBD self-diagnostic items. For detail,
refer to AT-85, "SELF-DIAGNOSTIC RESULT MODE" .
OBD Function for A/T System
BCS000OD
The ECM provides emission-related on board diagnostic (OBD) 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
BCS000OE
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. — 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 Diagnostic Trouble Code (DTC)
BCS000OF
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, P0720 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.
SAT014K
AT-98

[EURO-OBD]
If the DTC is being detected currently, the time data will be “0”.

SAT015K
D
If a 1st trip DTC is stored in the ECM, the time data will be “1t”.
E

G
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-102, "CONSULT-II Function (ENGINE)" .
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.
Priority

Items
Freeze frame data

Fuel Injection System Function — DTC: P0171, P0172, P0174, P0175
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 cleared 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. For details, refer to EC-48, "Emission-related Diagnostic Information" .

DTC U1000 CAN COMMUNICATION LINE
[EURO-OBD]
DTC U1000 CAN COMMUNICATION LINE
Description
PFP:31940
BCS000OH
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 malfunction 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 is an OBD self-diagnostic item.
Diagnostic trouble code “P0731 A/T 1ST GR FNCTN” with CONSULT-II is detected when A/T cannot be
shifted to the 1st gear position even if electrical circuit is good.
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 above

This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosis
malfunction.
This malfunction is detected when the A/T does not shift into fourth gear position or the torque converter
clutch does not lock up as instructed by the TCM. This is not caused by electrical malfunction (circuits
open or shorted) but by mechanical malfunction such as control valve sticking, improper solenoid valve
operation, malfunctioning oil pump or torque converter clutch, etc.

This is an OBD self-diagnostic item.
Diagnostic trouble code “P0734 A/T 4TH GR FNCTN” with CONSULT-II is detected when A/T cannot be
shifted to the 4th gear position even if electrical circuit is good.
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 A is stuck open or 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 A stuck open: 2, 2, 3 and 3* positions
In case of gear position with shift solenoid valve B stuck closed: 1, 2, 2 and 1* positions to each gear
position above
*: “P0734 A/T 4TH GR FNCTN” is detected.

BCS000Q2
The torque converter clutch solenoid valve is activated, with the gear in D4 and D3 , by the TCM in
response to signals sent from the vehicle speed sensor 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) on lock-up condition, the engine speed should
not change abruptly. If there is an abrupt change in engine speed, there is no lock-up.

This is an OBD self-diagnostic item.
Diagnostic trouble code “P0744 A/T TCC S/V FNCTN” with CONSULT-II is detected when A/T cannot perform lock-up even if electrical circuit is good.
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

The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in
response to signals sent from the TCM.
The line pressure duty cycle value is not constant when the closed throttle position switch is ON. To
confirm the line pressure duty cycle at low-pressure, the accelerator (throttle) should be open until the
closed throttle position switch is OFF.
CONSULT-II Reference Value
Display value (Approx.)

The turbine revolution sensor (power train revolution sensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automatic transaxle. The vehicle speed sensor A/T (Revolution
sensor) is located on the output side of the automatic transaxle. With the two sensors, input and output rpms
are accurately detected. As a result, optimal shift timing during deceleration and shift quality can be improved.

The torque converter clutch solenoid valve is activated, with the gear in D4 and D3 , by the TCM in
response to signals sent from the vehicle speed sensor 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) on lock-up condition, the engine speed should
not change abruptly. If there is an abrupt change in engine speed, there is no lock-up.

Diagnostic trouble code “A/T 1ST GR FNCTN” with CONSULT-II is detected when A/T cannot be shifted
to the 1st gear position even if electrical circuit is good.
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 above

Diagnostic trouble code “A/T 4TH GR FNCTN” with CONSULT-II is detected when A/T cannot be shifted
to the 4th gear position even if electrical circuit is good.
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 A stuck open: 2, 2, 3 and 3* positions
In case of gear position with shift solenoid valve B stuck closed: 1, 2, 2 and 1* positions to each gear
position above
*: “A/T 4TH GR FNCTN” is detected.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BJS000AI
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.

Precautions for Working with HFC-134a (R-134a)
BJS000AK
WARNING:
●
Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If lubricant other than that specified is used, compressor malfunction is likely to occur.
●
The specified HFC-134a (R-134a) lubricant 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 lubricant from a sealed container. Immediately reseal containers of lubricant. Without proper sealing, lubricant will become moisture saturated and should not be used.
–
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and lubricant
manufacturers.
–
Do not allow lubricant (Nissan A/C System Oil Type R) to come in contact with styrofoam parts.
Damage may result.
General Refrigerant Precautions
BJS000AL

PRECAUTIONS
●
●
●
●
●
●
●
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.
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.

CAUTION:
G
When replacing or cleaning refrigerant cycle components, observe the following.
●
When the compressor is removed, store it in the same position as it is when mounted on the car.
Malfunction to do so will cause lubricant to enter the low-pressure chamber.
H
●
When connecting tubes, always use a torque wrench and a back-up wrench.
●
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 operaI
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.
●
Allow components stored in cool areas to warm to working area temperature before removing seal
ATC
caps. This prevents condensation from forming inside A/C components.
●
Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
●
Always replace used O-rings.

BJS000AO
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 Lubricant Quantity in Compressor” exactly. Refer to ATC-17, "Maintenance of Lubricant Quantity in Compressor" .
Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubricant, wipe it off by using a clean waste cloth moistened with thinner.
After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.
After replacing the compressor magnet clutch, apply voltage to the new one and check for usual
operation.
Precautions for Service Equipment

ATC-8
PRECAUTIONS
VACUUM PUMP
A
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pressure. So the vacuum pump lubricant 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 placed near the hoseto-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.

●
●
●
●
●
●
●
●
BJS000AQ
The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(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.
The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluorescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to pinpoint refrigerant leaks.
For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.
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.
Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis
during a 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
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.
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 system or CFC-12 (R-12) leak detector dye
in HFC-134a (R-134a) A/C system or A/C system damage may result.
The fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction
occurs.

REFRIGERATION SYSTEM
REFRIGERATION SYSTEM
Refrigerant Cycle
PFP:KA990
A
BJS000AU
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 is
controlled by an externally equalized expansion valve, located inside the evaporator case.
FREEZE PROTECTION
B
C
Under usual operating conditions, when the A/C is switched ON, the compressor runs continuously, and the
evaporator pressure, and therefore, temperature is controlled by the compressor to prevent freeze up.
Refrigerant System Protection
BJS000AV
D
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.
ECM makes the A/C relay go OFF and stops the compressor when pressure on the high-pressure side
detected by refrigerant pressure sensor is over about 2,746 kPa (27.46 bar, 28.0 kg/cm2 , 398 psi), or below
about 134 kPa (1.34 bar, 1.4 kg/cm2 , 20 psi).
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 unusual level [more than 3.8MPa (38 bar,
38.76 kg/cm2 , 551 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into the atmosphere.

Drain the lubricant from the old (removed) compressor into a graduated container and recover the amount
of lubricant drained.
Drain the lubricant from the new compressor into a separate, clean container.
Measure an amount of new lubricant installed equal to amount drained from old compressor. Add this
lubricant to new compressor through the suction port opening.
Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant
to new compressor through the suction port opening.
If the liquid tank also needs to be replaced, add another 5 m (0.2 Imp fl oz.) of lubricant at this time.
Do not add this 5 m (0.2 Imp fl oz.) of lubricant only when replaces the compressor.

When A/C switch, AUTO switch or DEF switch is pressed, auto amp. inputs compressor ON signal to BCM.
BCM sends compressor ON signal to ECM, via CAN communication line.
ECM judges whether compressor can be turned ON, based on each sensor status (refrigerant-pressure sensor signal, throttle angle, etc.). If it judges compressor can be turned ON, it sends compressor ON signal to
IPDM E/R, via CAN communication line.
Upon receipt of compressor ON signal from ECM, IPDM E/R turns air conditioner relay ON to operate compressor.

CAN Communication System Description
BJS000B5
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-27,

System Operation
The auto amp. receives data from each of the sensors. When a drive signal is input from auto amp. to door
motor, a step motor built into the door motor rotates according to the drive signal, and then stops at the position of target door.
Mode door changes to manual select mode by pressing MODE/DEF switch of the controller. That allows mode
door to be fixed.
Pressing AUTO switch allows automatic control by auto amp., and mode door is fixed in the FOOT position by
pressing OFF switch.
During automatic operation of mode door, mode door position (VENT, B/L, FOOT) is selected according to the
temperature of discharge air calculated by auto amp. based on the target opening angle of air mix door and
the amount of sunload. And only when ambient temperature is extremely low with the mode door in the FOOT
position, D/F is selected and prevents windshield fogging.

Start up from COLD SOAK Condition (Automatic mode)
In a cold start up condition where the engine coolant temperature is below 56°C, 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, at which time the blower speed will increase to the objective speed.
Start up from usual or HOT SOAK Condition (Automatic mode)
ATC-72
TROUBLE DIAGNOSIS
The blower will begin operation momentarily after the A/C switch 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).
A
Blower Speed Compensation
Sunload
When the in-vehicle temperature and the set temperature are very close, the blower will be operating at low
speed. The low speed will vary depending on the sunload. During conditions of low or no sunload, the blower
low speed is usual low speed (approx. 4.0V). During high sunload conditions, auto amp. causes the blower
speed to increase (approx. 6.5V).

Ambient Sensor Circuit

COMPONENT DESCRIPTION
Ambient Sensor
The ambient sensor (1) is attached on the radiator core support
upper. It detects ambient temperature and converts it into a resistance value which is then input into the auto amp.
B
C
D
MJIB0467E
AMBIENT TEMPERATURE INPUT PROCESS
The auto amp. 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 auto amp. function. It only
allows the auto amp. to recognize an ambient temperature increase of 0.33°C (0.6°F) per 100 seconds.
As an example, consider stopping for a few minutes 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
BJS000BR
A
COMPONENT DESCRIPTION
Sunload Sensor
The sunload sensor (1) is located on the instrument upper mask. 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 auto amp.
B
C
D
MJIB0431E
SUNLOAD INPUT PROCESS
The auto amp. 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
BJS000CN
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant 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 1 to 2 inches per second and no further than 1/4 inch 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

E
BJS000CO
1.
Check A/C system for leaks using the UV lamp and safety goggles [SST: J-42220] in a low sunlight area
(area without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a F
bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indicates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
G
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner [SST: J-43872] to prevent future misdiagnosis.
H
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
leak detector.
NOTE:
I
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
ATC
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.

7.
Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.45 bar, 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 [SST: J-41459].
Connect the injector tool to the A/C low-pressure side service fitting.
Start engine and switch A/C ON.
When the A/C 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 manufacture’s operating instructions).
With the engine still running, disconnect the injector tool from the service fitting.
CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system
connection and proceed with the service procedures.
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 minutes to days for the dye to
penetrate a leak and become visible.

REFRIGERANT LINES
CHECKING PROCEDURE
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 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.
3.
4.
Check if the A/C refrigerant pressure is at least 345 kPa (3.45 bar, 3.52 kg/cm2 , 50 psi) above 16°C. If
less than specification, recover/evacuate and recharge the system with the specified amount of refrigerant.
NOTE:
At temperatures below 16°C, leaks may not be detected since the system may not reach 345 kPa (3.45
bar, 3.52 kg/cm2 , 50 psi).
Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet f) to the
low-pressure side (evaporator drain hose g to shaft seal k). Refer to ATC-137, "Components" . Perform a
leak check for the following areas carefully. Clean the component to be checked and move the leak
detected probe completely around the connection/component.

Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. 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.
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.
If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
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.
Start engine.
Set the heater A/C control as follows;
A/C switch: ON
MODE door position: VENT (Ventilation)
Intake door position: Recirculation
Temperature control dial: Max. cold
Fan speed: High
Run engine at 1,500 rpm for at least 2 minutes.

10. Turn engine off and perform leak check again following steps 4
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.
11. Before connecting ACR4 to vehicle, check ACR4 gauges. No
refrigerant pressure should be displayed. If pressure is displayed, recover refrigerant from equipment lines.
12. Discharge A/C system using approved refrigerant recovery
equipment. Repair the leaking fitting or component if necessary.
13. Evacuate and recharge A/C system and perform the leak test to confirm no refrigerant leaks.
14. Perform A/C performance test to ensure system works properly.

BKS001C3
The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic
interference, etc.). Check the symptoms below to diagnose the malfunction.
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment, and then determine the cause.
NOTE:
● CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be
incorrectly mastered by the customer on a computer.
● Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact Disc Standard and may not play.

Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources, 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 a time difference between the broadcast waves directly from the

CAN COMMUNICATION CONTROL
B
CAN communication is capable of dealing with a lot of information through the two communication lines (CAN
L line, CAN H line) connecting control units in the system. Also each control unit functions to transmit and
receive data, and reads necessary information only.
C
BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
D
1. CAN communication status
● With ignition switch ON, CAN communicates with other control units normally.
● Control by BCM is being operated properly.
E
● 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.
F
2. Pre-sleep status
● This is the status to stop CAN communication when ignition switch is turned OFF.
● It transmits sleep request signal to IPDM E/R and combination meter.
G
● Two seconds after CAN communication with another control unit stops, it switches to CAN communication inactive status.
H
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.
I
● Two seconds after CAN communication with another control unit stops, it switches to CAN communication inactive status.
4. Sleep status
J
● BCM is activated with low-current-consumption mode.
● CAN communication is not active.
● When CAN communication operation is detected, it switches to CAN communication status.
BCS
● When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
● It changes combination switch reading function.

CAN Communication
BKS0026S
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.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
BIS000HV
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.

CAN Communication

BIS000I8
SYSTEM DESCRIPTION
G
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.

CAN Communication
BIS000IZ
SYSTEM DESCRIPTION
A
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.

BIS000K6
The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock
function) and start the engine (engine start function) by carrying the Intelligent Key, which operates based
on the results of electrical key-ID verification using two-way communications between the Intelligent Key
and the vehicle.
Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote control entry system. (Remote control entry functions)
As an ignition key warning function, when a door lock is locked or unlocked with door request switch or
Intelligent Key button operation, the hazard lamps flashes and sound the Intelligent Key buzzer.
Even if the vehicle or Intelligent Key battery runs out, the door locks can be locked and unlocked and the
engine can be initiated by the mechanical key built-in the Intelligent Key.
If Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be
registered.
It has been made possible to diagnose the system, change the function setting and register Intelligent Key
with the CONSULT-II.
DOOR LOCK FUNCTION
Operation Description
When the driver door, passenger door, or back door request switch is pressed, Intelligent Key unit sends a
request signal from the transmission antenna corresponding to the pressed door request switch, key-ID
verification is performed using two-way communication with Intelligent Key, and if ID is successfully verified, a door lock/unlock request signal is sent to BCM (Body Control Module) through CAN communication
to lock/unlock the door lock.
●
With the locking operation of door request switch, door lock actuators of all doors will be locked.
Driver side door request switch operation
●
When door request switch (driver side) is pressed, driver side door lock actuator will be unlocked.
●

Intelligent Key Lock-in Prevention Function
When Intelligent Key is within the vehicle, a door is open or doors are locked using door lock and unlock
switch, driver door lock knob or door request switch, Intelligent Key unit sends door unlock request signal to
BCM via CAN communication to unlock all doors to prevent Intelligent Key from being locking in vehicle.
CAUTION:
The functions mentioned above are operable when the Intelligent Key is inside the vehicle. However,
there may be times that the Intelligent Key cannot be detected in some blind spot of the inside key
antennas. Thus engine start function system might not response when the Intelligent Key is placed on
the instrument panel, rear parcel shelf or in the glove box. Furthermore, by placing the Intelligent Key
in the door pocket and opening the door may interrupt the communication between the Intelligent Key
and the antennas.
REMOTE CONTROL ENTRY FUNCTIONS
Door Lock Function
●
●
Operating the button on the Intelligent Key sends the Intelligent Key-ID signals to the Intelligent Key unit.
Intelligent Key unit conducts a verification of the received key-ID, and if the verification is accepted, a door
lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock the door lock.
When door lock/unlock is performed using Intelligent Key button operation, confirmation is conducted by
making hazard lamps flashes and Intelligent Key warning buzzer sounds.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
BFS0007Q
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.

BFS0007S
Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
Recommended fluid is brake fluid “Nissan Genuine Brake Fluid or DOT 3 or DOT 4 (US FMVSS No.116)”.
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, disc brake caliper and wheel cylinder, use new brake fluid.
Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
Use a flare nut wrench when removing flare nuts, and use a flare
nut torque wrench when tightening flare nuts.
Always tighten brake lines to the specified torque when installing.
Before working, turn ignition switch OFF and disconnect electrical connector of ABS actuator and electric unit (control unit) or
the battery cables.
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.

types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
C
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 perD
formed 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
E
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 harness connecBRC
tors.

Recommended fluid is brake fluid “Nissan Genuine Brake Fluid or DOT 3 or DOT 4 (US FMVSS No.116)”.
Do not reuse the drained brake fluid.
Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.
Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.
Using a flare nut torque wrench, securely tighten brake tube
flare nuts.
Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble malfunctioning parts. If any malfunctioning part is found, replace the part with a new one.
Before working, turn ignition switch OFF and disconnect connectors for ABS actuator and electric unit or battery terminals.
When installing brake piping, be sure to check tightening torque.

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is a normal status of operation check.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
When an error is indicated by ABS or another warning lamp, collect all necessary information from the
customer (what symptoms are present under what conditions) and check for simple causes before starting diagnostic servicing. Besides the electrical system inspection, check booster operation, brake fluid
level, and oil leaks.
If tyre size and type are used in an improper combination, or brake pads are not Genuine Nissan parts,
stopping distance or steering stability may deteriorate.
If there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, ABS system
may malfunction or return an error.
If aftermarket parts (e.g. car stereo equipment, CD player) have been installed, check electrical harnesses
for pinches, open, and improper wiring.

ABS Function
●
●
●
BFS00096
Anti-lock Brake System monitors wheel rotation in braking and electronically controls braking force (brake
fluid pressure) to prevent wheel locking. Thus, it improves vehicle stability in abrupt braking and allows
driver to clear obstacles more easily.
In the event of an electric system malfunction, the fail-safe function will operate, the vehicle will enter the
ABS non-operation state, and ABS warning lamp will come on.
CONSULT-II can be used to diagnose the electrical system.
●
●
BFS00097
The electronically controlled braking force distribution unit detects the minute slips that occur in front and
rear wheels during braking and uses electronic control to control rear wheel braking force (brake hydraulic
pressure) to suppress rear wheel slipping as much as possible to improve stability during braking.
In the event an electrical system malfunction occurs, the fail-safe function will operate and EBD and ABS
will enter non-operational states, and ABS warning lamp and brake warning lamp will come on.
CONSULT-II can be used to diagnose the electrical system.

TROUBLE DIAGNOSIS
Diagnosis Procedure
PFP:00004
BFS0009A
BASIC CONCEPT
●
●
The most important point in performing trouble diagnosis is to thoroughly understand the vehicle systems
(both control and mechanical).
It is also important to clarify customer concerns before starting
the inspection.
First of all, reproduce the symptom, and understand it fully.
Ask the customer about his/her complaints carefully. In some
cases, it will be necessary to check the symptoms by driving the
vehicle with the customer.
CAUTION:
Customers are not professional. It is dangerous to make an
easy guess like “maybe the customer means that...,” or
“maybe the customer mentions this symptom”.
EFJ0028D
●
●
●
●
It is essential to check symptoms right from the beginning in
order to repair a error completely.
For an intermittent error, it is important to reproduce the symptom based on an interview with the customer and past examples. Do not perform an inspection on an ad hoc basis. Most
intermittent errors are caused by poor contacts. In this case, it
will be effective to shake the suspected harness or connector by
hand. When repairs are performed without any symptom diagnosis, no one can judge if the error has actually been eliminated.
After completing trouble diagnosis, be sure to perform “erase
memory”. Refer to BRC-19, "ERASE MEMORY" .
SEF233G
For an intermittent error, move the harness or harness connector by hand to check for poor contact or false open circuit.
Always read the GI section to be aware of the general precautions. Refer to GI-4, "General Precautions" .

CAN Communication
BFS000EY
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.

Check fluid level in brake reservoir tank. If fluid level is low, refill the brake fluid.
Check area around the brake piping and ABS actuator for leaks. If a leak or oozing is detected, check as
follows:
● If ABS actuator connections are loose, tighten piping to the specified torque. Check again for leaks, and
make sure there is no fluid leakage.
● If flare nuts at the connections and the threads of ABS actuator are damaged, replace damaged parts.
Then check again for leaks, and make sure that there is no fluid leak.
● If a leak or oozing is detected on other parts than ABS actuator connections, wipe the applicable part
with a clean cloth. Then check again for leaks, and if there is still a leak or oozing, replace damaged
part.
● If leaks or oozing are detected on ABS actuator body, wipe with a clean cloth and check again. If there
is still a leak or oozing, replace ABS actuator.

Recommended fluid is brake fluid “Nissan Genuine Brake Fluid or DOT 3 or DOT 4 (US FMVSS No.116)”.
Do not reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.
Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.
Using a flare nut torque wrench, securely tighten brake tube
flare nuts.
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 connectors of ABS actuator and electric unit (control unit) or
battery negative terminals.
When installing brake piping, be sure to check torque.
After removing/installing any hydraulic parts of the brake or ESP

During ESP/TCS/ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This
is normal.
When starting engine, or just after starting vehicle, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
When an error is indicated by ABS or another warning lamp, collect all necessary information from the
customer (what symptoms are present under what conditions) and check for simple causes before starting diagnostic servicing. Besides the electrical system inspection, check booster operation, brake fluid
level, and fluid leaks.
If tyre size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ESP/TCS/ABS
function may have a malfunction or error.

If the following components are replaced with non-genuine components or converted, ESP OFF indicator
lamp and SLIP indicator lamp may turn on or the ESP system may not operate properly. Components
related to suspension (Shock Absorber, Strut, Spring, Bush, etc.), Tyres, wheels (exclude specified size),
components related to brake (Pad, Rotor, Caliper, etc.), components related to engine (Muffler, ECM,
etc.), components related to body reinforcement (Roll bar, Tower bar, etc.).
Driving in the condition of breakage or excessive wear of suspension, tyres or components related to the
brakes may cause ESP OFF indicator lamp and SLIP indicator lamp turn on, and the ESP system may not
operate properly.
When the TCS or ESP is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and ESP.
When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the ESP may not operate normally, or ESP warning lamp and SLIP indicator
lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after restarting
engine.
Sudden turns (such as spin turns, acceleration turns), drifting, etc. When ESP function is OFF (ESP SW
ON) may cause the G -sensor system indicate a malfunction. However, this is not a malfunction, if normal
operation can be resumed after restarting engine.

BFS000A8
In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected
from steering angle sensor and pressure sensor, and the vehicle's driving status (amount of under steering / over steering) is determined from information from G-sensor, wheel sensor, etc., and this information
is used to improve vehicle stability by controlling the braking and engine power to all four wheels.
SLIP indicator lamp flashes to inform the driver of ESP operation.
During ESP operation, body and brake pedal lightly vibrate and mechanical noises may be heard. This is
normal.
ABS warning lamp, ESP OFF indicator lamp, and SLIP indicator lamp might turn on when vehicle is subject to strong shaking or large vibration, such as when vehicle is on a turn table, a ship or a steep slope
such as bank while engine is running. In this case, restart engine on a normal road, and if ABS warning

BFS000A9
The wheel spin of the drive wheels is detected by ABS actuator and electric unit (control unit) from the
wheel speed signals from four wheels, so if wheel spin occurs, drive wheel right and left brake fluid pressure control and engine fuel cut are performed while throttle value is restricted to reduce the engine
torque and decrease the amount of wheel spin. In addition, the degree throttle is opened is controlled to
achieve the optimum engine torque.
Depending on road circumstances, the driver may have a sluggish feel. This is normal, because the optimum traction has the highest priority under TCS operation.
TCS may be activated any time vehicle suddenly accelerates, suddenly down/upshifts, or is driven on a
road with a varying surface friction coefficient.
During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.
ABS Function

BFS000AA
The anti-lock brake system is a function that detects wheel revolution while braking, and it improves handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.
If the electrical system breaks down, then the fail-safe function starts, the ABS becomes inoperative, and
ABS warning lamp turns on.
Electrical system diagnosis by CONSULT-II is available.
During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

NOTE:
In condition 1 described above, an ABS self-diagnosis sound may be heard. That is a normal condition
because a self-diagnosis for “Key Switch ON” and “the First Starting” are being performed.

CAN COMMUNICATION
[ESP/TCS/ABS]
CAN COMMUNICATION
System Description
PFP:23710
BFS000AE
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.
Refer to LAN-27, "CAN Communication Unit" .

How to Proceed With Diagnosis
PFP:00004

BFS000AG
BASIC CONCEPT
●
Most important point to perform diagnosis is to understand systems (control and mechanism) in vehicle
thoroughly.
●
It is also important to clarify customer complaints before inspection.
First of all, reproduce symptom, and understand it fully.
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptom by driving vehicle with
customer.
NOTE:
Customers are not professionals. Do not assume “maybe customer means...” or “maybe customer mentioned this symptom”.

●
It is essential to check symptoms right from beginning in order to
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptom based on interview with customer and past examples.
Do not perform inspection on ad hoc basis. Most intermittent
malfunctions are caused by poor contacts. In this case, it will be
effective to shake suspected harness or connector by hand.
When repairs are performed without any symptom check, no
one can judge if malfunction has actually been eliminated.
After diagnosis, make sure to carry out “erase memory”. Refer to
BRC-62, "ERASE MEMORY" .
SEF233G
For an intermittent malfunction, move harness or harness connector by hand to check poor contact or false open circuit.
Always read “GI General Information” to confirm general precautions. Refer to GI-4, "General Precautions" .

Complaints against malfunction vary depending on each person.
It is important to clarify customer complaints.
Ask customer about what symptoms are present and under
what conditions. Use information to reproduce symptom while
driving.
It is also important to use diagnosis sheet so as not to miss information.

PRECAUTIONS FOR DIAGNOSIS
●
●
●
●
●
●
●
●
●
Before performing diagnosis, always read precautions. Refer to BRC-49, "How to Proceed With Diagnosis" .
If ABS actuator and electric unit (control unit), steering angle sensor, steering system parts or suspension
system parts have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of
steering angle sensor before driving. Refer to BRC-42, "Adjustment of Steering Angle Sensor Neutral
Position" .
After diagnosis is finished, be sure to erase memory. Refer to BRC-62, "ERASE MEMORY" .
When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector terminals.
For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.
If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.
To use CONSULT-II to perform self-diagnosis of ABS actuator and electric unit (control unit), active tests,
or work support, first stop work, then connect CONSULT-II and select “ABS”.
While self-diagnostic results of CONSULT-II shows malfunction, if CONSULT-II active test is performed,
an engine system error may be indicated. In this case, start engine to resume the normal screen.
ESP/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:
Symptom
Symptom description
Result
This is noise of motor inside ABS actuator and electric unit (control unit).
Slight noise may occur during ESP, TCS, and ABS operation.
Motor operation noise
When the vehicle speed goes over 10 km/h (6 MPH), motor and valves
operating noise may be heard. It happens only once after IGN (ignition)
is ON. This is a normal status of the system operation check.
System operation check
noise
When engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check.
Normal
Normal
TCS may activate momentarily if wheel speed changes when driving
over location where friction coefficient varies, when up/downshifting, or
when fully depressing accelerator pedal.
ESP/TCS operation
(SLIP indicator lamp blinking)
For inspection of speedometer or other instruments, press
ESP OFF SW to turn ESP/TCS function off.
When accelerator pedal is depressed on a chassis dynamometer, vehicle speed will not increase. This is not normal. It is result of TCS being
activated by stationary front wheels. Warning lamp may also illuminate
to indicate “sensor system error”. This is also normal, and is the result of
the stationary front wheels being detected. To be certain, restart engine,
and drive vehicle at 30 km/h (19 MPH) or above. Make sure warning
lamp does not illuminate.
Normal
Cancel the ESP/TCS
function for the
inspection on a chassis dynamometer.
ABS operation (Longer stopping distance)
On roads with low friction coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. Therefore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low.
Normal
Insufficient feeling of acceleration
Depending on road conditions, driver may feel that feeling of acceleration is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation.

Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
Check brake piping and around ABS actuator and electric unit (control unit) for leaks. If there is leaking or
oozing fluid, check the following items.
● If ABS actuator and electric unit (control unit) connection is loose, tighten piping to the specified torque
and re-perform the leak inspection to make sure there are no leaks.
● If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-perform the leak inspection to make sure there are no leaks.
● When there is fluid leaking or oozing from a part other than ABS actuator and electric unit (control unit)
connection, if fluid is just oozing out, use a clean cloth to wipe off the oozing fluid and re-check for
leaks. If fluid is still oozing out, replace the damaged part.
● When there is fluid leaking or oozing at ABS actuator and electric unit (control unit), if fluid is just oozing
out, use a clean cloth to wipe off oozing fluid and re-check for leaks. If fluid is still oozing out, replace
ABS actuator and electric unit (control unit) body.
CAUTION:
ABS actuator and electric unit (control unit) body cannot be disassembled.
Check brake pad degree of wear. Refer to BR-21, "PAD WEAR INSPECTION" and BR-28, "INSPECTION AFTER REMOVAL" .

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
BKS000Z9
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.

CAN Communication
BKS000ZF
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul- J
tiplex 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. DI
Each control unit transmits/receives data but selectively reads required data only.

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.

PRECAUTIONS
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BBS003ZU
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.
Maintenance Information
BBS005AP
If any of following part is replaced, always replace with new* one.
If it's not (or fail to do so), the electrical system may not be operated properly.
*: New one means a virgin control unit that has never been energized on-board.

PIIB3706J
On Board Diagnostic (OBD) System of Engine
BBS002TD
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) 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 MI to light up.
EC-26
PRECAUTIONS
[CR (WITH EURO-OBD)]
●
●
●
●
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease, A
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-88, "HAR- EC
NESS CONNECTOR" .
Be sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MI to light up due to the short circuit.
C
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI 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 D
before returning the vehicle to the customer.
Precaution
●
●
●
●
BBS002TE
E
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.

Do not disassemble ECM.
If battery cable is disconnected, the memory will return to
the initial ECM values.
The ECM will now start to self-control at its initial values.
Engine operation can vary slightly when the cable is disconnected. However, this is not an indication of a malfunction. Do not replace parts because of a slight variation.
If the battery is disconnected, the following emission

●
When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
Securely connect ECM harness connectors.
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-95, "ECM Terminals and Reference Value" .
Handle manifold absolute pressure sensor carefully to
avoid damage.
Do not clean air clear element 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),
crankshaft position sensor (POS).
After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function
Check should be a good result if the repair is completed.

When measuring ECM signals with a circuit tester, connect
a break-out box (SST) and Y-cable adapter (SST) between
the ECM and ECM harness connector.
When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the ECM's
transistor. Use a ground other than ECM terminals, such as
the ground.

SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
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 volume) from the crankshaft position sensor (POS), camshaft
position sensor (PHASE) and the manifold absolute pressure sensor.
VARIOUS FUEL INJECTION INCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compensated to improve engine performance under various operating conditions as listed below.

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 A
heated oxygen 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
heated oxygen sensor 1, refer to EC-178 . This maintains the mixture ratio within the range of stoichiometric
EC
(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 heated oxygen sensor 1 shift, the air-fuel ratio is controlled to stoichiometric by the signal C
from heated oxygen sensor 2.
Open Loop Control
D
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 heated oxygen sensor 1 or its circuit
●
Insufficient activation of heated oxygen sensor 1 at low engine coolant temperature
●
High engine coolant temperature
●
During warm-up
●
When starting the engine

MIXTURE RATIO SELF-LEARNING CONTROL
The mixture ratio feedback control system monitors the mixture ratio signal transmitted from heated oxygen
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., manifold absolute pressure sensor silicon diaphragm)
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 heated oxygen 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.

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.
EC-35
ENGINE CONTROL SYSTEM
[CR (WITH EURO-OBD)]
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.
FUEL SHUT-OFF
Fuel to each cylinder is cut off during deceleration or operation of the engine at excessively high speeds or
operation of the vehicle at excessively high speeds.

SYSTEM DESCRIPTION
Firing order: 1 - 3 - 4 - 2
The ignition timing is controlled by the ECM to maintain the best air-fuel ratio for every running condition of the
engine. The ignition timing data is stored in the ECM.
The ECM receives information such as the injection pulse width and camshaft position sensor signal. Computing this information, ignition signals are transmitted to the power transistor.
During the following conditions, the ignition timing is revised by the ECM according to the other data stored in
the ECM.
●
At starting
●
During warm-up
●
At idle
●
At low battery voltage
●
During acceleration
The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed
within the anti-knocking zone, if recommended fuel is used under dry conditions. The retard system does not
operate under normal driving conditions. If engine knocking occurs, the knock sensor monitors the condition.
The signal is transmitted to the ECM. The ECM retards the ignition timing to eliminate the knocking condition.

SYSTEM DESCRIPTION
If the engine speed is above 2,500 rpm with no load (for example, the shift position is neutral and engine
speed is over 2,500 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies
EC
based on engine speed.
Fuel cut will operate until the engine speed reaches 2,000 rpm, then fuel cut is cancelled.

BBS003ZE
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 elec- EC
tronic 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.

EVAPORATIVE EMISSION SYSTEM
Description
PFP:14950
BBS00343
SYSTEM DESCRIPTION
PBIB0491E
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.

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.

*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator (MI) 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-81 .)
Two Trip Detection Logic
F
I
BBS002TW
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 MI 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 MI lights up. The MI 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 MI, and store
DTC and Freeze Frame data, even in the 1st trip, as shown below.

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 MI 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 MI lights up. In other words,
the DTC is stored in the ECM memory and the MI 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 MI during the
1st trip, the DTC and 1st trip DTC are stored in the ECM memory.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
[CR (WITH EURO-OBD)]
Procedures for clearing the DTC and the 1st trip DTC from the ECM memory are described in EC-57, "HOW
TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
For malfunctions in which 1st trip DTCs are displayed, refer to EC-48, "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 ISO 15031-5. 1st trip DTC detection occurs without lighting up the
MI 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-75, "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: P0112, P1217, P1805, etc.
These DTCs are prescribed by ISO 15031-5.
(CONSULT-II also displays the malfunctioning component or system.)
No Tools
The number of blinks of the MI in the Diagnostic Test Mode II (Self-Diagnostic Results) indicates the DTC.
Example: 0112, 1217, 1805 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-104, "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/MI 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.

EC
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-57, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
System Readiness Test (SRT) code is specified in Service $01 of ISO 15031-5.
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 MI 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”.
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”.

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 72 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 72 and ground is lower than 1.4V).
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.
*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: Checking the vehicle speed with GST is advised.

TEST VALUE AND TEST LIMIT (GST ONLY — NOT APPLICABLE TO CONSULT-II)
The following is the information specified in Service $06 of ISO 15031-5.
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.

When there is an open circuit on MI circuit, the ECM can not warn the driver by lighting up MI 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 has a malfunction and MI circuit is open by
means of operating fail-safe function.
The fail-safe function also operate when above diagnoses except MI circuit are detected and demands the
driver to repair the a malfunction.

PBIA3905E
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 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-22, "INDEX FOR DTC" )

RELATIONSHIP BETWEEN MI, 1ST TRIP DTC, DTC, AND DETECTABLE ITEMS
●
●
●
●
●
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 MI will come on. For details, refer to EC-47, "Two Trip Detection
Logic" .
The MI 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.

CAUTION:
●
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
●
The fuel hose connection method used when taking fuel pressure check must not be used for
other purposes.
●
Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains sealability with O-rings inside.
●
When installing fuel hose quick connector, refer to EM-18, "AIR CLEANER AND AIR DUCT" .
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because E11 models do not have fuel return system.
1. Release fuel pressure to zero. Refer to EC-71, "FUEL PRESSURE RELEASE" .
2. Prepare fuel hose and fuel hose clamp for fuel pressure check, and connect fuel pressure gauge.
● Use suitable fuel hose for fuel pressure check (genuine NISSAN fuel hose without quick connector).
● To avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure check.
● Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
● Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-18, "AIR CLEANER AND AIR DUCT" .
● Do not twist or kink fuel hose because it is plastic hose.

TROUBLE DIAGNOSIS
Trouble Diagnosis Introduction
PFP:00004
BBS002U1
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-75 .
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-79 should be used.
Start your diagnosis by looking for conventional malfunctions first.
This will help troubleshoot driveability malfunctions on an electronically controlled engine vehicle.

Detected items
Engine operating condition in fail-safe mode
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.

Throttle position sensor
P1121
Electric throttle control
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.
H
(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.
I
P1122
Electric throttle control

ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P1124

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.

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 accelerator pedal is depressed, engine speed will not rise more than 2,500 rpm
due to fuel cut.
When there is an open circuit on MI circuit, the ECM can not warn the driver by lighting up MI when there
is a malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses is continuously detected
as NG for 5 trips, ECM warns the driver that engine control system has a malfunction and MI circuit is
open by means of operating fail-safe function.
The fail-safe function also operate when above diagnoses except MI circuit are detected and demands
the driver to repair the malfunction.
Engine operating condition in fail-safe mode
G
(When electric throttle control actuator does not function properly due to the return
spring malfunction:)
ECM controls the electric throttle control actuator by regulating the throttle opening
around the idle position. The engine speed will not rise more than 2,000 rpm.
(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 Neutral position, and engine speed will not exceed 1,000 rpm
or more.

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 in the figure, 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 ...

Operation
1.
2.
“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-25, "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.

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 MONI- EC
TOR (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 C
MI.
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 cor- D
rection)

BBS002UI
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
incident 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
BBS002UM
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.

BBS002UN
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.

BBS002VT
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.

BBS002W0
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, the ECM enters fail-safe mode and the MI 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.

To judge the malfunction of heated oxygen sensor 1, this diagnosis
measures response time of heated oxygen sensor 1 signal. The time
is compensated by engine operating (speed and load), fuel feedback
control constant, and heated oxygen sensor 1 temperature index.
Judgment is based on whether the compensated time (heated oxygen sensor 1 cycling time index) is inordinately long or not.

Component Description
PFP:226A0
BBS002X6
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the heated oxygen 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
BBS002X8
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 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 heated oxygen sensor 1. The
ECM calculates the necessary compensation to correct the offset between the actual and the theoretical

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 heated oxygen sensors 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 MI (2 trip detection logic).

Component Description

A
BBS002XN
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.

When the malfunction is detected, the ECM enters fail-safe mode and the MI 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.

PFP:00000
On Board Diagnosis Logic
BBS002XV
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crankshaft position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is occurring.
Sensor

ECM Function
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 MI 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 MI will turn off.
If another misfire condition occurs that can damage the TWC on a second trip, the MI will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MI will remain on.
If another misfire condition occurs that can damage the TWC, the MI 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 MI 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.

Component Description
PFP:23731
BBS002Y5
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
A
BBS002YD
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.
ECM receives the signals as shown in the figure.

*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.

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.

BBS00306
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Component Description

BBS0030E
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

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 heated oxygen 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 minimum voltage of sensor is
sufficiently low during the various driving condition such as fuel-cut.

DTC P1147 HO2S2
Component Description
PFP:226A0
BBS0030V
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 heated oxygen 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
BBS0030X
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.

ECM computes two intake air volume values.
1: Computed from manifold absolute pressure signal and intake air temperature signal.
2: Computed from engine revolution signal and throttle position signal.
In normal condition, value 1 is used for engine control.
If intake air leak occurred between throttle valve and intake air port, manifold absolute pressure sensor signal
might increase, and then ECM increases amount of fuel injected. In this case, ECM uses value 2 for engine
control instead of value1.
ECM monitors the difference between value 1 and value 2. If the difference is extremely large, ECM judges
intake air leak occurs and light up the MI

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.

DTC P2122, P2123 APP SENSOR
Component Description
PFP:18002
A
BBS0032H
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the acceleraEC
tor 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
C
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
D
these signals and controls the throttle control motor based on these
signals.
PBIB1741E
Idle position of the accelerator pedal is determined by the ECM
E
receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation such as fuel cut.

FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
Engine operating 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.

DTC P2127, P2128 APP SENSOR
Component Description
PFP:18002
BBS0032P
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.
PBIB1741E
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.

FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
Engine operating 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 throttle valve to be slower than the normal condition.
So, the acceleration will be poor.

DTC P2138 APP SENSOR
Component Description
PFP:18002
A
BBS00335
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the acceleraEC
tor 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
C
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
D
these signals and controls the throttle control motor based on these
signals.
PBIB1741E
Idle position of the accelerator pedal is determined by the ECM
E
receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation such as fuel cut.

FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
Engine operating 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.

FUEL INJECTOR
Component Description
PFP:16600
A
BBS0033I
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 several seconds after the ignition switch is turned ON to improve engine
startability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and 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.

On Board Diagnostic (OBD) System of Engine
BBS0034O
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) 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 MI to light up.
EC-455
PRECAUTIONS
[CR (WITHOUT EURO-OBD)]

●
●
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI 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-88, "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 MI to light up due to the short circuit.
Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM.
Precaution

●
●
BBS0034P
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.

Securely connect ECM harness connectors.
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-512, "ECM Terminals and Reference Value"
.
Handle manifold absolute pressure sensor carefully to
avoid damage.
Do not clean air clear element 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),
crankshaft position sensor (POS).
After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function

SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
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 volume) from the crankshaft position sensor (POS), camshaft
position sensor (PHASE) and the manifold absolute pressure sensor.

MIXTURE RATIO FEEDBACK CONTROL (CLOSED LOOP CONTROL)
PBIB2938E
EC-463
K
L
M
ENGINE CONTROL SYSTEM
[CR (WITHOUT EURO-OBD)]
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
heated oxygen 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
heated oxygen sensor 1, refer to EC-577 . 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 heated oxygen 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 heated oxygen sensor 1 or its circuit
●
Insufficient activation of heated oxygen sensor 1 at low engine coolant temperature
●
High engine coolant temperature
●
During warm-up
●
When starting the engine
MIXTURE RATIO SELF-LEARNING CONTROL
The mixture ratio feedback control system monitors the mixture ratio signal transmitted from heated oxygen
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., manifold absolute pressure sensor silicon diaphragm)
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 heated oxygen 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
SEF337W
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.
EC-464
ENGINE CONTROL SYSTEM
[CR (WITHOUT EURO-OBD)]
Simultaneous Multiport Fuel Injection System
Fuel is injected simultaneously into all four cylinders twice each engine cycle. In other words, pulse signals of A
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.
EC
FUEL SHUT-OFF
Fuel to each cylinder is cut off during deceleration or operation of the engine at excessively high speeds or
operation of the vehicle at excessively high speeds.

SYSTEM DESCRIPTION
Firing order: 1 - 3 - 4 - 2
The ignition timing is controlled by the ECM to maintain the best air-fuel ratio for every running condition of the
engine. The ignition timing data is stored in the ECM.
The ECM receives information such as the injection pulse width and camshaft position sensor signal. Computing this information, ignition signals are transmitted to the power transistor.
During the following conditions, the ignition timing is revised by the ECM according to the other data stored in
the ECM.
●
At starting
●
During warm-up
●
At idle
●
At low battery voltage
●
During acceleration
The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed
within the anti-knocking zone, if recommended fuel is used under dry conditions. The retard system does not
operate under normal driving conditions. If engine knocking occurs, the knock sensor monitors the condition.
The signal is transmitted to the ECM. The ECM retards the ignition timing to eliminate the knocking condition.

If the engine speed is above 2,500 rpm with no load (for example, the shift position is neutral and engine
speed is over 2,500 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies
based on engine speed.
Fuel cut will operate until the engine speed reaches 2,000 rpm, then fuel cut is cancelled.

System Description
PFP:23710
BBS003ZH
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.

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
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.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Introduction
PFP:00028

The ECM has an on board diagnostic system, which detects malfunctions related to engine sensors or actuators. The ECM also records various emission-related diagnostic information including:
Emission-related diagnostic information
Diagnostic Trouble Code (DTC)
Freeze Frame data
1st Trip Diagnostic Trouble Code (1st Trip DTC)
1st Trip Freeze Frame data
The above information can be checked using procedures listed in the table below.

*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator (MI) 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-498 .)
Two Trip Detection Logic
BBS00357
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 MI 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 MI lights up. The MI 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.
When there is an open circuit on MI circuit, the ECM can not warn the driver by lighting up MI when there is a
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 has malfunction and MI circuit is open by
means of operating fail-safe function.
The fail-safe function also operate when above diagnoses except MI 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

*3: The troubleshooting for this DTC needs CONSULT-II.
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 MI 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 MI lights up. In other words,

the DTC is stored in the ECM memory and the MI 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 fail-safe items, DTC is stored in the ECM memory even in the 1st trip.
Procedures for clearing the DTC and the 1st trip DTC from the ECM memory are described in EC-478, "HOW
TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION"
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-492, "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
CONSULT-II displays the DTC in “SEFL-DIAG RESULTS” mode. Examples: P0117, P0340, P1065, etc.
(CONSULT-II also displays the malfunctioning component or system.)
Without CONSULT-II
The number of blinks of the MI in the Diagnostic Test Mode II (Self-Diagnostic Results) indicates the DTC.
Example: 0107, 0340, 1065 etc.
●
1st trip DTC No. is the same as DTC No.
●
Output of a DTC indicates a malfunction. However, 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. For
details, see EC-521, "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/MI 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. 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-478, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .

played, they may be either DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified
codes can be identified by using the CONSULT-II. A DTC will be used as an example for how to read a code.
PBIA3905E
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 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-451, "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 EC480, "HOW TO SWITCH DIAGNOSTIC TEST MODE" .
●
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.

CAUTION:
●
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
●
The fuel hose connection method used when taking fuel pressure check must not be used for
other purposes.
●
Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains sealability with O-rings inside.
●
When installing fuel hose quick connector, refer to EM-18, "AIR CLEANER AND AIR DUCT" .
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because E11 models do not have fuel return system.
1. Release fuel pressure to zero. Refer to EC-488, "FUEL PRESSURE RELEASE" .
2. Prepare fuel hose and fuel hose clamp for fuel pressure check, and connect fuel pressure gauge.
● Use suitable fuel hose for fuel pressure check (genuine NISSAN fuel hose without quick connector).
● To avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure check.
● Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
● Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose. Refer to EM-18, "AIR CLEANER AND AIR DUCT" .

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.
EC

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.

A visual check only may not find the cause of the incidents. A road
test with CONSULT-II or a circuit tester connected should be performed. Follow the Work Flow on EC-492 .
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-496 should be used.
Start your diagnosis by looking for conventional malfunctions first.

Throttle position sensor
The ECM controls the electric throttle control actuator in regulating the throttle opening

So, the acceleration will be poor.
P1121
Electric throttle control
actuator
(When electric throttle control actuator does not function properly due to the return
spring malfunction:)
ECM controls the electric throttle control 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 Neutral position and engine speed will not exceed 1,000 rpm
or more.

When accelerator pedal is depressed, engine speed will not rise more than 2,500 rpm
due to fuel cut.
ECM stops the electric throttle control actuator control, throttle valve is maintained at a

Normal
When accelerating
Poor acceleration
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 MI circuit, the ECM can not warn the driver by lighting up MI when there
is a malfunction on engine control system.
Therefore, when electrical controlled throttle and part of ECM related diagnoses is continuously detected
as NG for 5 trips, ECM warns the driver that engine control system has a malfunction and MI circuit is
open by means of operating fail-safe function.
The fail-safe function also operate when above diagnoses except MI 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 in the figure, 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.
MBIB0295E
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.
SEF707X
Operation
1.
2.
“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-25, "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.

BBS0035N
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
MI.
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 (The mean value of air-fuel ratio feedback correction factor per cycle)

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
Description
PFP:00006
BBS0035R
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
incident 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 Incident Report Situations

POWER SUPPLY AND GROUND CIRCUIT
[CR (WITHOUT EURO-OBD)]
Ground Inspection
BBS0035V
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-38, "Ground Distribution" .

DTC P0122, P0123 TP SENSOR
Component Description
PFP:16119
BBS0036N
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, the ECM enters fail-safe mode and the MI 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.

BBS0037B
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the heated oxygen 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

BBS0037J
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, the ECM enters fail-safe mode and the MI 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.

DTC P0335 CKP SENSOR (POS)
Component Description
PFP:23731
A
BBS0037Y
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.

BBS00386
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.

DTC P1111 IVT CONTROL SOLENOID VALVE
Component Description
PFP:23796
BBS0038M
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.

ECM computes two intake air volume values.
1: Computed from manifold absolute pressure signal and intake air temperature signal.
2: Computed from engine revolution signal and throttle position signal.
In normal condition, value 1 is used for engine control.
If intake air leak occurred between throttle valve and intake air port, manifold absolute pressure sensor signal
might increase, and then ECM increases amount of fuel injected. In this case, ECM uses value 2 for engine
control instead of value1.
ECM monitors the difference between value 1 and value 2. If the difference is extremely large, ECM judges
intake air leak occurs and light up the MI

Overall Function Check
BBS00482
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap (Models without A/C) or reservoir tank cap (Models with A/C) when the
engine is hot. Serious burns could be caused by high pressure fluid escaping from the radiator (Models without A/C) or reservoir tank (Models with A/C).
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.

Component Description

BBS0039Y
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.

Component Description
PFP:18002
A
BBS003AQ
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the acceleraEC
tor 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
C
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
D
these signals and controls the throttle control motor based on these
signals.
PBIB1741E
Idle position of the accelerator pedal is determined by the ECM
E
receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation such as fuel cut.

When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
Engine operating 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.

DTC P2127, P2128 APP SENSOR
Component Description
PFP:18002
BBS003AY
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.
PBIB1741E
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.

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 throttle valve to be slower than the normal condition.
So, the acceleration will be poor.

DTC P2138 APP SENSOR
Component Description
PFP:18002
A
BBS003BE
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the acceleraEC
tor 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
C
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
D
these signals and controls the throttle control motor based on these
signals.
PBIB1741E
Idle position of the accelerator pedal is determined by the ECM
E
receiving the signal from the accelerator pedal position sensor. The ECM uses this signal for the engine operation such as fuel cut.

FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
Engine operating 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.

*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
I
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.

FUEL INJECTOR
Component Description
PFP:16600
BBS003CS
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 several seconds after the ignition switch is turned on to improve engine
startability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and 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.

The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

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 heated oxygen 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 Diagnostic (OBD) System of Engine and A/T
BBS0048U
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) 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 MI to light up.
EC-809
PRECAUTIONS
[HR (WITH EURO-OBD)]
●
●
●
●
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI 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-88, "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 MI 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 MI 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
●

●
●
BBS0048V
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.

When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
Securely connect ECM harness connectors.
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-883, "ECM Terminals and Reference Value"
.
Handle mass air flow sensor carefully to avoid damage.
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),
crankshaft position sensor (POS).
After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function

SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
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 the crankshaft position sensor (POS), camshaft position
sensor (PHASE) and the mass air flow sensor.

ENGINE CONTROL SYSTEM
[HR (WITH EURO-OBD)]
MIXTURE RATIO FEEDBACK CONTROL (CLOSED LOOP CONTROL)
PBIB2953E
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
heated oxygen 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
heated oxygen sensor 1, refer to EC-967, "DTC P0133 HO2S1" . 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 heated oxygen 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 heated oxygen sensor 1 or its circuit
●
Insufficient activation of heated oxygen 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 heated oxygen
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 heated oxygen 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.

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 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.

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.

SYSTEM DESCRIPTION
Firing order: 1 - 3 - 4 - 2
The ignition timing is controlled by the ECM to maintain the best air-fuel ratio for every running condition of the
engine. The ignition timing data is stored in the ECM.
The ECM receives information such as the injection pulse width and camshaft position sensor (PHASE) signal. Computing this information, ignition signals are transmitted to the power transistor.
During the following conditions, the ignition timing is revised by the ECM according to the other data stored in
the ECM.

During acceleration
The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed
within the anti-knocking zone, if recommended fuel is used under dry conditions. The retard system does not
operate under normal driving conditions. If engine knocking occurs, the knock sensor monitors the condition.
The signal is transmitted to the ECM. The ECM retards the ignition timing to eliminate the knocking condition.

CAN COMMUNICATION
System Description
PFP:23710
BBS00494
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.
Refer to LAN-21, "CAN COMMUNICATION" , about CAN communication for detail.

PBIB3039E
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.

POSITIVE CRANKCASE VENTILATION
Description
PFP:11810
BBS00498
SYSTEM DESCRIPTION
PBIB2962E
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.

*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator (MI) 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-870, "FailSafe Chart" .)
Two Trip Detection Logic
BBS0049B
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 MI 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 MI lights up. The MI 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 MI, and store
DTC and Freeze Frame data, even in the 1st trip, as shown below.

When there is an open circuit on MI circuit, the ECM cannot warn the driver by lighting up MI 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 MI circuit is open by means
of operating fail-safe function.

*3: In Diagnostic Test Mode II (Self-diagnostic results), this number is controlled by NISSAN.
*4: The troubleshooting for this DTC needs CONSULT-II.
*5: When engine is running, MI may flash. For details, refer to EC-844, "MI Flashing Without DTC" .
*6: When the fail-safe operations for both self-diagnoses occur at the same time, the MI illuminates.
*7:This self-diagnosis is not for ECM power supply circuit, even though “ECM BACK UP/CIRCUIT” is displayed on CONSULT-II screen.
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 MI 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 MI lights up. In other words,
the DTC is stored in the ECM memory and the MI 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 MI 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-841, "HOW
TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
For malfunctions in which 1st trip DTCs are displayed, refer to EC-831, "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 ISO 15031-5. 1st trip DTC detection occurs without lighting up the
MI 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-864, "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.

J
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, P0740, P1217, etc.
These DTCs are prescribed by ISO 15031-5.
(CONSULT-II also displays the malfunctioning component or system.)
No Tools
The number of blinks of the MI in the Diagnostic Test Mode II (Self-Diagnostic Results) indicates the DTC.
Example: 0340, 0740, 1217, 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-893, "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/MI 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
2
3
Items
Freeze frame data
Misfire — DTC: P0300 - P0304
Fuel Injection System Function — DTC: P0171, P0172
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-841, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
SYSTEM READINESS TEST (SRT) CODE
System Readiness Test (SRT) code is specified in Service $01 of ISO 15031-5.
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.
EC-834
ON BOARD DIAGNOSTIC (OBD) SYSTEM
[HR (WITH EURO-OBD)]
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 A
vehicle is returned to the customer untested.
NOTE:
If MI is ON during the state emissions inspection, the vehicle is also returned to the customer untested even EC
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
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”.
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”.
SRT Service Procedure
If a vehicle has failed the state emissions inspection due to one or more SRT items indicating “INCMP”, review

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 38 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 38 and ground is lower than 1.4V).
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.
*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

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).
NOTE:
If the DTC is not for A/T related items (see EC-803, "INDEX FOR DTC" ), skip steps 2 through 4.
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
2. Turn CONSULT-II ON and touch “A/T”.
3. Touch “SELF-DIAG RESULTS”.

When there is an open circuit on MI circuit, the ECM cannot warn the driver by lighting up MI 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 MI circuit is open by means
of operating fail-safe function.
EC-843

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 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-803, "INDEX FOR DTC" .)

RELATIONSHIP BETWEEN MI, 1ST TRIP DTC, DTC, AND DETECTABLE ITEMS
●
●
●
●
●
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 MI will come on. For details, refer to EC-830, "Two Trip Detection
Logic" .
The MI 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.

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 MI 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.
●

TROUBLE DIAGNOSIS
Trouble Diagnosis Introduction
PFP:00004
A
BBS0049L
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.
EC
C
D
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.
E
F
G
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-864, "WORK FLOW" .
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-868, "Worksheet Sample" 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 MI to come on steady or blink and
DTC to be detected. Examples:
●
Vehicle ran out of fuel, which caused the engine to misfire.

When the DTC listed below is detected, the ECM enters fail-safe mode and the MI 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.
P1121
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.
●
P1122
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.
P1124
P1126
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.
P1128
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.
P1229
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.
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 MI circuit, the ECM cannot warn the driver by lighting up MI 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 MI circuit is open by
means of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MI 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

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 ...
PBIB1593E
xx%”, “REAL-TIME DIAG” screen is also displayed.

2.
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.

“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-25, "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
BBS004A6
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-38, "Ground Distribution" .

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.

Component Description
PFP:22680
A
BBS004AN
The mass air flow sensor (1) 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

A
BBS004B9
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.

When the malfunction is detected, ECM enters fail-safe mode and the MI 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.

The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Component Description

A
BBS004BY
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

A
BBS004CF
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the heated oxygen 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 before the three way catalyst (manifold) causes the
longer switching time. To judge the malfunctions of heated oxygen
sensor 2, ECM monitors whether the voltage is unusually high 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 heated oxygen sensor 1. The
ECM calculates the necessary compensation to correct the offset between the actual and the theoretical

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 MI (2 trip detection logic).

DTC P0222, P0223 TP SENSOR
Component Description
PFP:16119
BBS004DC
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.

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.

DTC P0300 - P0304 MULTIPLE CYLINDER MISFIRE, NO. 1 - 4 CYLINDER MISFIRE
PFP:00000
On Board Diagnosis Logic
BBS004DK
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crankshaft position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is occurring.
Sensor
Crankshaft position sensor (POS)
Input Signal to ECM
ECM function

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 MI 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 MI will turn off.
If another misfire condition occurs that can damage the TWC on a second trip, the MI will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MI will remain on.
If another misfire condition occurs that can damage the TWC, the MI 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 MI 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)
[HR (WITH EURO-OBD)]
DTC P0335 CKP SENSOR (POS)
Component Description
PFP:23731
BBS004DU
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.

*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.
G
COMPONENT DESCRIPTION
I
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.

BBS004EY
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 P1121 ELECTRIC THROTTLE CONTROL ACTUATOR
Component Description
PFP:16119
BBS004F6
Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The throttle position sensor detects the throttle valve position, and the opening and closing speed of the throttle valve and feeds 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.

BBS004FV
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Component Description
PFP:226A0
A
BBS004GK
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the heated oxygen 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
BBS004GM
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 before 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.

DTC P1225 TP SENSOR
Component Description
PFP:16119
BBS004H9
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

BBS004HE
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.

DTC P2122, P2123 APP SENSOR
Component Description
PFP:18002
BBS004I2
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.
PBIB1741E
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.

An excessively high voltage from the APP
sensor 1 is sent to ECM.
Possible cause
●
Harness or connectors
(APP sensor 1 circuit is open or
shorted.)
●
Accelerator pedal position sensor
(APP sensor 1)
FAIL-SAFE MODE
When the malfunction is detected, ECM enters fail-safe mode and the MI lights up.
Engine operating 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
BBS004II
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, the ECM enters fail-safe mode and the MI 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.

FUEL INJECTOR
Component Description
PFP:16600
A
BBS004J3
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 several seconds after the ignition switch is turned ON to improve engine
startability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and 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.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
BBS004K4
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
C
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 perD
formed 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
E
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.
F
Maintenance Information
BBS005AT
If any of following part is replaced, always replace with new* one.
If it's not (or fail to do so), the electrical system may not be operated properly.
*: New one means a virgin control unit that has never been energized on-board.

On Board Diagnostic (OBD) System of Engine
BBS004K6
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) 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 MI to light up.
EC-1243
PRECAUTIONS
[HR (WITHOUT EURO-OBD)]
●
●
●
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI 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-88, "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 MI to light up due to the short circuit.
Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM
before returning the vehicle to the customer.
Precaution
●
●
●
●
BBS004K7
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.

Do not disassemble ECM.
If a battery cable is disconnected, the memory will return to
the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slightly when the terminal is disconnected. However, this is not an indication of a malfunction. Do not replace parts because of a slight variation.
If the battery is disconnected, the following emissionrelated diagnostic information will be lost within 24 hours.

●
When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
Securely connect ECM harness connectors.
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-1304, "ECM Terminals and Reference
Value" .
Handle mass air flow sensor carefully to avoid damage.
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),
crankshaft position sensor (POS).
After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Overall Function
Check should be a good result if the repair is completed.

SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
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 the crankshaft position sensor (POS), camshaft position
sensor (PHASE) and the mass air flow sensor.

MIXTURE RATIO FEEDBACK CONTROL (CLOSED LOOP CONTROL)
PBIB2953E
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
heated oxygen 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
heated oxygen sensor 1, refer to EC-1373, "DTC P0132 HO2S1" . 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 heated oxygen 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 heated oxygen sensor 1 or its circuit
●
Insufficient activation of heated oxygen 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 heated oxygen
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 heated oxygen 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.

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 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.

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.

The knock sensor retard system is designed only for emergencies. The basic ignition timing is programmed
within the anti-knocking zone, if recommended fuel is used under dry conditions. The retard system does not
operate under normal driving conditions. If engine knocking occurs, the knock sensor monitors the condition.
The signal is transmitted to the ECM. The ECM retards the ignition timing to eliminate the knocking condition.

BBS004KG
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.

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.

POSITIVE CRANKCASE VENTILATION
Description
PFP:11810
BBS004KK
SYSTEM DESCRIPTION
PBIB2962E
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.

*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator (MI) 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-1291, "FailSafe Chart" .)
Two Trip Detection Logic
BBS004KN
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 MI 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 MI lights up. The MI 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.
When there is an open circuit on MI circuit, the ECM cannot warn the driver by lighting up MI 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 MI circuit is open by means
of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MI 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

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 MI lights up. In other words,
the DTC is stored in the ECM memory and the MI 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 MI 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-1267, "HOW
TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
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-1285, "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
CONSULT-II displays the DTC in “SELF-DIAG RESULTS” mode. Examples: P0117, P0340, P1217, etc.
(CONSULT-II also displays the malfunctioning component or system.)
Without CONSULT-II
The number of blinks of the MI in the Diagnostic Test Mode II (Self-Diagnostic Results) indicates the DTC.
Example: 0117, 0340, 1217, etc.
●
1st trip DTC No. is the same as DTC No.
●
Output of a DTC indicates a malfunction. However, 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. For
details, see EC-1314, "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/MI 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.
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-1267, "HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .

ON BOARD DIAGNOSTIC (OBD) SYSTEM
[HR (WITHOUT EURO-OBD)]
Malfunction Indicator (MI)
BBS004KP
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
If the MI does not light up, refer to DI-32, "WARNING LAMPS" ,
or see EC-1596, "MI & DATA LINK CONNECTORS" .
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.

Function
Explanation of Function
Mode I
Ignition switch in
ON position
BULB CHECK
This function checks the MI bulb for damage (blown, open
circuit, etc.).
If the MI does not come on, check MI circuit.
Engine running
MALFUNCTION
WARNING
This is a usual driving condition. When a malfunction is
detected twice in two consecutive driving cycles (two trip
detection logic), the MI will light up to inform the driver that
a malfunction has been detected.
One trip detection diagnoses will light up the MI in the 1st
trip.
Ignition switch in
ON position
SELF-DIAGNOSTIC
RESULTS
This function allows DTCs and 1st trip DTCs to be read.
HEATED OXYGEN SENSOR 1
MONITOR
This function allows the fuel mixture condition (lean or
rich), monitored by heated oxygen sensor 1, to be read.
Engine stopped
Mode II
Engine stopped
Engine running
When there is an open circuit on MI circuit, the ECM cannot warn the driver by lighting up MI 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 MI circuit is open by means
of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MI 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

This DTC number is clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC RESULTS)
DIAGNOSTIC TEST MODE II — SELF-DIAGNOSTIC RESULTS
In this mode, the DTC and 1st trip DTC are indicated by the number of blinks of the MI as shown below.
The DTC and 1st trip DTC are displayed at the same time. If the MI does not illuminate in diagnostic test mode
I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MI illuminates in diagnostic test mode II (SELF-DIAGNOSTIC RESULTS), it is a DTC; if two or more codes are displayed, they may be either DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified
codes can be identified by using CONSULT-II. A DTC will be used as an example for how to read a code.
PBIA3905E
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 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-1239, "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 EC1269, "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.

FUEL PRESSURE CHECK
CAUTION:
●
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
●
The fuel hose connection method used when taking fuel pressure check must not be used for
other purposes.
●
Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains sealability with O-rings inside.
●
Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/
C, etc.) Fuel pressure gauge may indicate false readings due to varying engine load and changes
in manifold vacuum.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because E11 models do not have fuel return system.
1. Release fuel pressure to zero. Refer to EC-1281, "FUEL PRESSURE RELEASE" .
2. Prepare fuel hose for fuel pressure check B and fuel tube
adapter (KV10118400) D, then connect fuel pressure gauge A.
●
: To quick connector
: To fuel tube (engine side)
● C: Clamp
● Use suitable fuel hose for fuel pressure check (genuine NISSAN fuel hose without quick connector).
● To avoid unnecessary force or tension to hose, use moderately long fuel hose for fuel pressure check.
● Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
● Use Pressure Gauge to check fuel pressure.
Remove fuel hose. Refer to EM-120, "INTAKE MANIFOLD" .
● Do not twist or kink fuel hose because it is plastic hose.
Connect fuel hose for fuel pressure check (1) to fuel tube

TROUBLE DIAGNOSIS
Trouble Diagnosis Introduction
PFP:00004
BBS004KW
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 a circuit tester connected should be performed. Follow the Work Flow on EC-1285, "WORK FLOW" .
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-1289, "Worksheet Sample" should be used.
Start your diagnosis by looking for conventional malfunctions first.
This will help troubleshoot driveability malfunctions on an electronically controlled engine vehicle.

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.
P1121
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.
A
EC
C
D
E
(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.
P1122
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.
P1124
P1126
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.
P1128
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.
P1229
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.
P1805
Brake switch
ECM controls the electric throttle control actuator by regulating the throttle opening to a
small range.
Therefore, acceleration will be poor.

When engine is idling
Normal
When accelerating
Poor acceleration
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 MI circuit, the ECM cannot warn the driver by lighting up MI 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 MI circuit is open by
means of operating fail-safe function.
The fail-safe function also operates when above diagnoses except MI 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

REAL TIME DIAGNOSIS IN DATA MONITOR MODE (RECORDING VEHICLE DATA)
Description
A
CONSULT-II has two kinds of triggers and they can be selected by touching “SETTING” in “DATA MONITOR”
mode.
EC
1. “AUTO TRIG” (Automatic trigger):
● The malfunction will be identified on the CONSULT-II screen
in real time.
C
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
D
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
E
“STOP” is touched on the screen during “Recording Data ...
PBIB1593E
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
F
“Recording Speed”. Refer to CONSULT-II OPERATION MANUAL.
2. “MANU TRIG” (Manual trigger):
G
● DTC/1st trip DTC and malfunction item will not be displayed
automatically on CONSULT-II screen even though a malfunction is detected by ECM.
H
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.
● 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-25, "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.

CONSULT-II Reference Value in Data Monitor
BBS004L6
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.

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
Description
PFP:00006
BBS004LC
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.

Ground Inspection
BBS004LG
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:
EC-1342
POWER SUPPLY AND GROUND CIRCUIT
[HR (WITHOUT EURO-OBD)]
Remove the ground bolt or screw.
A
Inspect all mating surfaces for tarnish, dirt, rust, etc.
●
Clean as required to assure good contact.
●
Reinstall bolt or screw securely.
EC
●
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
C
eyelet make sure no ground wires have excess wire insulation.
For detailed ground distribution information, refer to PG-38, "Ground Distribution" .

BBS004LH
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 P0102, P0103 MAF SENSOR
Component Description
PFP:22680
BBS004LY
The mass air flow sensor (1) 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.

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.

When the malfunction is detected, ECM enters fail-safe mode and the MI 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
BBS004ML
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Component Description
PFP:226A0
BBS004N1
The heated oxygen sensor 2, after three way catalyst (manifold),
monitors the oxygen level in the exhaust gas.
Even if switching characteristics of the heated oxygen 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
BBS004N3
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 before the three way catalyst (manifold) causes the
longer switching time. To judge the malfunctions of heated oxygen
sensor 2, ECM monitors whether the voltage is unusually high during
the various driving condition such as fuel-cut.

BBS004N9
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.

BBS004NO
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
A
BBS004NW
The camshaft position sensor (PHASE) senses the protrusion of
camshaft (INT) 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.

BBS004OB
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 P1121 ELECTRIC THROTTLE CONTROL ACTUATOR
Component Description
PFP:16119
BBS004OJ
Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The throttle position sensor detects the throttle valve position, and the opening and closing speed of the throttle valve and feeds 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 MI lights up.
Detected items
Engine operating condition in fail-safe mode
Malfunction A
The 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.
Malfunction B

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.

Component Description
PFP:18002
BBS004QH
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.
PBIB1741E
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.

Component Description

A
BBS004QX
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, the ECM enters fail-safe mode and the MI 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.

*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.

FUEL INJECTOR
Component Description
PFP:16600
A
BBS004RO
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 several seconds after the ignition switch is turned ON to improve engine
startability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and 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.

A
BBS004S0
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
BBS003ZY
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
C
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 perD
formed 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
E
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.
F
Maintenance Information
BBS005AU
If any of following part is replaced, always replace with new* one.
If it's not (or fail to do so), the electrical system may not be operated properly.
*: New one means a virgin control unit that has never been energized on-board.

PIIB3706J
On Board Diagnostic (OBD) System of Engine
BBS003ZZ
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:
●
Be sure to turn the ignition switch OFF and disconnect the battery negative cable before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves,
etc. will cause the MI to light up.
EC-1603
PRECAUTIONS
[K9K]
●
●
●
●
●
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI 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-88, "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 MI 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 MI to light up due to the malfunction of the fuel system, etc.
Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM
before returning the vehicle to the customer.
Precautions
●
●
●
●
BBS00400
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
negative 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 negative cable.

●
●
When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in coil and condenser, thus resulting in
damage to IC's.
Keep engine control system harness at least 10cm (4 in)
away from adjacent harness, to prevent engine control system malfunctions due to receiving external noise, degraded
operation of IC's, etc.
Keep engine control system parts and harness dry.
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.
Even a slight leak in the air intake system can cause serious incidents.
Do not shock or jar the camshaft position sensor, crankshaft position sensor.
When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the ECM's
transistor. Use a ground other than ECM terminals, such as
the ground.
Do not disassemble fuel pump.
If NG, take proper action.
Do not disassemble fuel injector.
If NG, replace fuel injector.

CLEANLINESS INSTRUCTIONS WHICH MUST BE FOLLOWED WHEN WORKING ON THE
HIGH PRESSURE DIRECT INJECTION SYSTEM
Risks Relating to Contamination
The system is very sensitive to contamination. The risks caused by the introduction of contamination are:
●
Damage or destruction of the high pressure injection system and the engine
●
Seizing or leaking of a component
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles a few microns in size) get into the system during dismantling or into the circuits via the fuel unions.
The cleanliness principle must be applied from the filter to the fuel injectors.
WHAT ARE THE SOURCES OF CONTAMINATION?
Contamination is caused by:
●
Metal or plastic chips
●
Paint
●
fibres:
–
Boxes
–
Brushes
–
Paper
–
Clothing
–
Cloths
●
Foreign bodies such as hair
●
Ambient air
●
etc
IMPORTANT: It is not possible to clean the engine using a high pressure washer because of the risk of damaging connections. In addition, moisture may collect in the connectors and create electrical connection malfunctions.
INSTRUCTIONS TO BE FOLLOWED BEFORE ANY WORK IS CARRIED OUT ON THE INJECTION SYSTEM
●
●
●
Ensure that you have the plugs for the unions to be opened (bag of plugs sold at the Parts Store - Nissan
part No.: 16830 BN700, Renault part No.: 77 01 206 804). Plugs are to be used once only. After use, they

System Overview
BBS004TJ
The DCM1.2 injection system used on the K9K engine is an electronically-controlled high-pressure injection
system. The fuel is compressed by a high-pressure pump and then stored in a fuel rail that feeds the fuel injectors. Injection takes place when a current pulse applied to the fuel injector holder. The injection delivery is proportional to the fuel rail pressure and the length of pulse applied, and the start of injection is synchronised with
the start of the pulse.
The circuit comprises two sub-systems that can be distinguished from one another by the pressure level of the
fuel:
●
The low-pressure circuit comprises the reservoir, the fuel filter, the transfer pump and the fuel injector
holder return pipes
●
The high-pressure circuit consists of the high-pressure pump, the fuel rail, the fuel injector holders and the
high-pressure tubes
Finally, there are a certain number of regulation sensors and actuators that allow command and control of the
system as a whole.
Fuel Injection Control
BBS004TL
The high pressure injection system is intended to deliver a specific quantity of fuel to the engine at a specific
time.

ECM
●
The “common rail” direct high pressure injection system works sequentially.
●
This new injection system reduces operating noise, reduces the volume of pollutant gases and particles
and produces high engine torque at low engine speeds thanks to a pre-injection procedure.
●
The high pressure pump generates the high pressure sent to the fuel rail. The flow actuator on the pump
controls the quantity of fuel supplied according to the demand determined by the ECM. The fuel rail supplies each fuel injector through a steel pipe.
●
The ECM:
–
Determines the value of injection pressure necessary for the engine to operate well and then controls the
pressure regulator. It checks that the pressure value is correct by analyzing the value transmitted by the
fuel rail pressure sensor located on the fuel rail.
–
Determines the injection time necessary to deliver the right quantity of fuel and the moment when injection
should be started.
–
Controls each fuel injector electrically and individually after determining these two values.
●
The injected flow to the engine is determined by:
–
The duration of fuel injector control

The high pressure pump is supplied at low pressure by an integrated low pressure pump (transfer pump).
It supplies the fuel rail whose pressure is controlled for charge by the flow actuator and for discharging by
the fuel injector valves. Falls in pressure can be compensated for in this way. The flow actuator allows the E
high pressure pump to provide just the amount of fuel necessary to maintain the pressure in the fuel rail.
Thanks to this element, heat generation is minimized and engine output improved.
In order to discharge the fuel rail using the fuel injector valves, the valves are controlled by short electrical

impulses:
Short enough not to open the fuel injector, (through the return circuit from the fuel injectors)
Long enough to open the valves and discharge the fuel rail

The engine must not operate with:
Fuel containing more than 10% diester
Gasoline, even in tiny quantities
The system can inject the fuel into the engine at a pressure up to 1400 bars. Before carrying out any work,
check that the fuel rail is not under pressure and that the fuel temperature is not too high.
You must respect the cleaning and safety advice specified in this document for any work on the high pressure injection system.
Removal of the interior of the pump and fuel injectors is prohibited. Only the flow actuator, the fuel pump
temperature sensor and the venturi can be replaced.
For safety reasons, it is strictly forbidden to slacken a high pressure pipe union when the engine is running.
It is not possible to remove the fuel rail pressure sensor from the fuel rail because this may cause circuit
contamination malfunctions. If the fuel rail pressure sensor fails, the fuel rail pressure sensor, the fuel rail
and the five high pressure pipes must be replaced.
It is strictly forbidden to remove any injection pump pulley marked number 070 575. If the pump is being
replaced, the pulley must be replaced.
It is forbidden to repair the wiring connecting the knock sensor and the crankshaft positon sensor. If the
wiring should malfunction, it has to be replaced with new wiring.
Applying 12V directly to any component in the system is prohibited.
Ultrasonic carbon removal and cleaning are prohibited.
Never start the engine without the battery being connected correctly.
Disconnect the injection system ECM when carrying out any welding work on the vehicle.
It is essential to replace all the disconnected air intake plastic pipes.

Function: Fuel supply management (advance, delivery and pressure).
Quantity of fuel injected and regulation of injection advance.
The injection control parameters are the quantities to be injected and their respective advances.

●
Accelerator pedal position

The quantities to be injected and their respective advances are converted into:
●
Reference tooth
●
Time between this tooth and the start of the pulse
●
Time for which the fuel injector holder is fed
An electrical current (pulse) is sent to each fuel injector holder as a function of the previously calculated data.
The system performs between one and four injections (a pilot injection, a pre-injection, a main injection and a
post-injection). The general principle is to calculate a total delivery injected which will then be distributed
across the deliveries of the various injections to promote efficient combustion and a reduction in pollutant
emissions.
●
●
A knock sensor is used to control some of the deviations when the fuel is injected. This plays a number of
roles:
●
Protection of the engine by detecting injection losses (disabled on the basic version)
●
Checking of the pilot quantity by measurement of the deviations and dispersions
By modifying the duration on the one hand and the injection advance on the other, it is possible to readjust the
quantity of fuel injected and the instant of ignition of the mixture.
FUEL RAIL PRESSURE CONTROL
The quality of combustion is influenced by the size of the droplets atomised in the cylinder. In the combustion
chamber, smaller drops of fuel will have time to burn completely and not produce smoke or nonburned particles. To meet anti-pollution requirements it is necessary to reduce the size of the droplets and thus the injection holes.
The smaller these holes are, the less fuel can be introduced at a given pressure which limits the power. To
overcome this malfunction it is necessary to increase the quantity of fuel injected which in practice means
increasing the pressure (and the number of openings of the fuel injector nozzles). In the case of the Delphi
Common Rail, the pressure can reach 1600 bar in the fuel rail and must be permanently controlled. The measurement circuit is comprised an active fuel rail pressure sensor on the fuel rail linked to an analogue port of
the ECM.
The high-pressure pump is fed at low pressure (5 bar) by an integral transfer pump. This feeds the fuel rail, the
pressure of which is controlled for the charging by the fuel flow actuator (fuel pressure regulator) and for discharge by the fuel injector. This allows drops in pressure to be compensated. The fuel flow actuator (fuel pressure regulator) allows the high-pressure pump to only supply the quantity of fuel necessary to maintain the
pressure in the fuel rail. Thanks to this device, the generation of heat is minimised and the efficiency of the
engine is improved.
In order to discharge the fuel rail using the fuel injectors, the fuel injectors are operated by means of small
electrical pulses:
●
Sufficiently small not to open the fuel injector (the fuel passes through the return circuit from the fuel injectors)
●
Sufficiently long to open the valves and discharge the fuel rail
Surplus fuel is fed back to the fuel filter or to the reservoir according to its delivery. In the event of non-actuation of the fuel flow actuator (fuel pressure regulator), the pressure in the fuel rail is limited by a pressure relief
valve fitted on the pump.
IDLING CONTROL
The ECM is responsible for idling control. In practice it has to take into account the instantaneous power level
to be delivered as a function of the following elements:

INDIVIDUAL FUEL INJECTOR CORRECTION
The fuel injectors of the DCM1.2 system must be calibrated with fuel injector adjusting values in order to accurately set their delivery. Calibration of each fuel injector is performed for various pressures on a test bed and
the characteristics are shown on a label attached to the fuel injector holder body. These fuel injector adjusting
values are then entered in the ECM memory thereby allowing it to operate the fuel injectors taking into account
their manufacturing variance.

D
MEASUREMENT OF THE ANGULAR POSITION
Crankshaft position sensor (CKPS):
Measurement of the angular position is performed by means of a magneto-inductive sensor that is excited by
machined into the flywheel of the crankshaft. This flywheel comprises sixty teeth with a spacing of six degrees,
less two missing teeth to form a notch.
Camshaft position sensor (CMPS):
A second sensor (Hall effect) excited by a tooth machined in the drive pulley of the high-pressure pump (in
synch with the camshaft), rotates at half the speed of the engine and provides information on the operation of
the injection cycle.
By comparing the signals from these two sensors, the angular position subsystem (APS) of the ECM is capable of providing the system as a whole with the following synchronisation information: the angular position of
the flywheel, the speed, the number of the active fuel injector and the advance in the injection cycle.
This module also provides the system with information on the speed of rotation.

NEW PUMP HOUSING FUEL FLOW STRATEGY (PUMP FUEL FLOW)
Lubrication of the pump is by means of a fuel flow cycle during which the pump is filled and comes up to pressure before transferring the fuel to the fuel rail.
This lubrication is performed using a strategy known as “new pump housing fuel flow” which prevents starting
for around 10 seconds, which is the time needed for filling of the pump and starting.
For vehicles equipped with keys, if the key is released before this “first start-up” phase it is not necessary to
perform a power latch before proceeding to restart the vehicle.
This strategy applies following an initial start-up in the factory and then whenever there is a change of ECM if
the fuel rail pressure parameters are not copied over to the new ECM, or also following reprogramming of the
ECM.
I
J
K
VARIABLE LOW CAPACITY (VLC) FUNCTION
Due to the combination of a number of parameters such as the temperature of the fuel, wear of parts, clogging
of the fuel filter, and so on, the system′s limit may be reached during its lifetime. In this case, the pressure in
the fuel rail cannot be maintained because of a lack of capacity of the pump. In the event of a lack of pump
capacity, therefore, this strategy will reduce the delivery required to a value that allows the pressure controller
to re-check the pressure.
EGR VOLUME CONTROL VALVE OPERATION
The EGR system (exhaust gas recirculation) is comprised a direct current proportional EGR volume control
valve with integral potentiometer to read the position of the valve. The EGR volume control position is controlled in a closed circuit via the potentiometer and/or the change in the estimated air deliver
AIR DELIVERY CALCULATION
The delivery of fresh air that enters the engine is indicated by a mass air flow sensor. This mass air flow sensor allows management of the quantity of exhaust gas to be recirculated in order to guarantee the best recirculation rates. An intake air temperature sensor is incorporated in the mass air flow sensor.
Measurement of the air delivery allows closed-circuit control via the EGR volume control valve.
TURBO CONTROL

The turbo system is comprised a solenoid valve that allows control of the waste gate in order to create a boost
pressure or a depression in the admission circuit.

FUNCTION: STORED FUNCTIONS
Climate Control Management Assistance
With climate controlled models, the DCM1.2 system offers the possibility of deactivating the air conditioning
under certain usage conditions:
●
Intentional interruption by the driver
●
During the start-up phases
●
In the event of overheating (in order to reduce the power to be supplied by the engine)
●
When the speed is maintained at a very high level (protection of the compressor)
●
For temporary periods (such as strong acceleration demands during overtaking, anti-stalling and moving
off). These conditions are only taken into account where they occur repeatedly, in order to avoid instability
of the system (untimely deactivations)
●
When certain malfunctions arise
Cold Loop Climate Control
The climate control is the cold loop type and its management shared between a number of control units. The
ECM is responsible for:
●
Managing the demand for cold as a function of the controls in the passenger compartment and the pressure value
●
Determining the power absorbed by the compressor from the pressure
●
Determining the engine ventilator set commands as a function of the speed of the vehicle and the pressure
The driver turns on the climate control from the instrument panel. The information is sent to the ECM via the
CAN system. This demand for cold is authorised or declined as a function of the measured pressure. If this
pressure is outside the operational limits, the cold loop strategy is not activated.
NOTE:
These demands for operation of the air cooling set can be made from the ECM but they pass via the CAN.
These demands are a function of the climate control, but also the engine coolant temperature and the speed
of the vehicle.
Passenger Compartment Climate Control
A direct injection engine is characterised by injection of the fuel directly into the combustion chamber. The
result is a reduction in heat losses from the upper part of the engine and consequently a smaller cylinder head
cooling circuit is needed.
The effect of this reduction is that the temperature of the water passing through is increased more slowly. This
water is then used by the passenger compartment heating system. During severe cold spells, therefore, it
becomes difficult to quickly reach a comfortable temperature in the passenger compartment.
In order to limit the heating delay, air heating resistors are incorporated in the passenger compartment heating
circuit. The passenger compartment heating unit determines the need to operate the heating resistors, the
IPDM E/R physically controls the heating resistors and the ECM determines on the one hand as a function of
the alternator the operational power limits of the heating resistors and on the other when to disable the heating
resistors as a function of the engine speed, the load and the speed of the vehicle.
Idle Speed Control
BBS004TM
The ECM takes over calculation of the idle speed to maintain the idle speed at the recommended level and to
compensate for any variation in the mechanical or electrical couple as regards:
●
Engine coolant temperature
●
Battery voltage
●
Gear selected on the transmission
●
Electrical loads (climate control system, cooling fan assembly etc.)
●
Any malfunctions found
At the normal operating temperature, without high electrical load, the idle speed is 800 ± 50 rpm.

PURPOSE OF THE EGR SYSTEM
A
Exhaust gas recirculation is used to reduce the nitrogen oxide (NOx) content of the exhaust gases.
The ECM authorises gas to pass by controlling an EGR volume control valve.
OPERATING PRINCIPLE
The valve is controlled by an RCO (Opening Cyclic Ratio) signal sent by the ECM. The RCO signal modulates
the opening of the valve and consequently the quantity of exhaust gas directed back to the intake manifold.
The ECM continuously carries out a test to detect the position of the EGR volume control valve.
NOTE:
The position of the EGR volume control valve is determined by the calculation of the amount of air taken in by
the engine.
EC
C
D
OPERATING CONDITIONS
The parameters which determine the activation of the EGR volume control valve are as follows:
●
Engine coolant temperature
●
Intake air temperature
●
Ambient barometric pressure
●
Accelerator pedal position
●
Injected fuel flow
●
Engine speed
Operating point for the EGR volume control valve test:
The EGR volume control valve is activated when:
●
Intake air temperature is > 15 °C (59 °F) and engine coolant temperature is > 70 °C (158 °F)
●
Intake air temperature is > 50 °C (122 °F) and engine coolant temperature is > 40 °C (104 °F)
●
Engine speed is between 850 and 1,000 rpm
●
Injected fuel flow is between 2 and 5 mg/stroke
●

CAN Communication
BBS0040B
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.
Refer to LAN-27, "CAN Communication Unit" , about CAN communication for detail.

Injector Adjustment Value Registration
BBS0040E
There is a 16 digit code on the fuel injectors called injector adjustment value. This code is specific to each fuel
injector, and takes into account differences in manufacture and specifies the flow injected by each of them.
When a fuel injector is replaced, it is necessary to program the injector adjustment value of the new fuel injector into the ECM.
When an ECM is replaced, it is necessary to program the injector adjustment values of the four fuel injectors.
There are two possibilities:
●
If it is possible to communicate with the ECM:
–
Read out the data from the ECM using the “SAVE DATA FOR REPLACE” in “WORK SUPPORT” mode
with CONSULT-II.
–
Turn ignition switch OFF.
–
Remove battery negative cable.
–
Change the ECM.
–
Reprogram the data from the “WRITE DATA AFTER REPLACE” in “WORK SUPPORT” mode with CONSULT-II to the replaced ECM.
–
After replacement, ensure that the ECM has not detected malfunctions relating to the injector adjustment
value and check that the MI is turned OFF.
●
If it is not possible to communicate with the ECM:
–
Turn ignition switch OFF.
–
Remove battery negative cable.
–
Change the ECM.
–
Read the data on the fuel injectors.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Introduction
PFP:00028
BBS0040I
The ECM controls the display on the instrument panel of certain information relating to the operation of the
engine.
Four functions are involved here: The OBD malfunction indicator [MI(Yellow)] for the EOBD (European On
Board Diagnostics), the pre/post heating, the engine coolant temperature and engine malfunction [MI(Red)].
These four functions are represented by four lights given out by the ECM
PRE/POST HEATING LAMP
This lamp indicates that the pre-heating has been activated.
ENGINE COOLANT TEMPERATURE LIGHT
This light is used as an indicator of engine overheating.
●
In the event of overheating, it is up to the driver whether to stop the vehicle or not.
OBD LIGHT
The OBD malfunction indicator [MI(Yellow)] is used to alert the driver to the existence of engine control system
malfunctions involving excessive pollution or if the EOBD system is deactivated.
The ECM makes a request for lighting of the MI(Yellow) only where there is a malfunction present at the end of
three consecutive cycles.
The 3-second visual check upon powering up (automatic test procedure controlled by the IPDM E/R) is performed by the ECM.
In the event of a confirmed OBD malfunction by lighting of the OBD light, no flashing of the light must be
observed following the lighting test.

with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedure of NATS initialization and all NATS ignition key ID registration, refer to
CONSULT-II operation manual, NATS.
REPLACING THE ECM
This vehicle is fitted with an engine immobilizer system which is controlled by a key recognition system.
The ECM is supplied without a code but they must all be programmed with one.
If an ECM is replaced, it must be programmed with the code of the vehicle and the correct operation of the
engine immobilizer function must be checked.
WARNING:
These vehicles have a special ECM which does not function unless it is coded.
Consequently, it is strongly recommended that you do not carry out tests using ECMs borrowed from
the warehouse or on another vehicle to prevent coding and uncoding malfunctions which may leave
the ECM useless.
UNCODING PROCEDURE
If the ECM has learnt a code and must be returned to the workshop, it is imperative that you uncode it before
removing it.

PREREQUISITES FOR TROUBLE DIAGNOSIS
To begin trouble diagnosis, it is essential to have the following items available:
Documentation Type
Diagnostic procedures:
●
Assisted with CONSULT-II, Service Manual.
●
Wiring diagrams.
Special tool required PLUGGED RAIL tools
REMINDERS
Trouble Diagnosis:
There are present DTCs and stored DTCs (which appeared in a certain context and have since disappeared
or which are still present but have not had trouble diagnosis performed on them in the current context).
The “present” or “stored” status of DTCs must be considered when activating the diagnostic tool after power is
supplied to the ECM (without activating the system components).
Deal with present DTCs according to the procedure specified in the corresponding DTC trouble diagnosis.
For stored DTCs, note the DTCs displayed and follow the instructions in the Notes section.
If the DTC is confirmed when the instructions in the Notes section are applied, the malfunction is present. Deal
with the DTC.
If the DTC is not confirmed, check:
●
Electrical lines which correspond to the malfunction
●
Connectors for these lines (for oxidation, bent pins, etc.)
●
Resistance of the malfunction component
●
Condition of the wires (melted or cut insulation, wear)
Conformity Check
The conformity check is designed to check the states and data monitor items which do not display any DTCs
on the diagnostic tool when inconsistent. This phase therefore allows:
●
Diagnoses malfunctions that do not have a DTC display, and which may correspond to a customer complaint.
●
Checks that the system is operating correctly and that there is no risk of a DTC reappearing after repairs.
This section gives the trouble diagnosis procedures for states and parameters and the conditions for checking
them.
If a state is not operating normally or a data monitor value is outside permitted tolerance values, you should
consult the corresponding trouble diagnosis page.
Customer Complaints - Trouble Diagnosis
If the test with the CONSULT-II is OK, but the customer complaint still present, the malfunction should be
treated by customer complaints.
A synopsis of the general procedure to follow is provided on the next page in the form of a flow chart.

Wiring Control
Diagnostics malfunctions
Removing the connectors and/or handling the wirings may temporarily remove the origin of a DTC. The measurements of the electrical voltages, resistance and insulation are generally correct, especially when the DTC
is not present at the time of the analysis (stored DTC).
Visual Check
Look for impacts under the bonnet and in the passenger compartment.
Perform a careful check of the protections, insulation and correct running of wirings.
Look for traces of oxidation.
Tactile Check
While manipulating the wirings, use the diagnostic tool to detect a change in DTC states from “stored” to
“present”.
Ensure that the connectors are correctly engaged.
Apply light stresses to the connectors.
Gently manipulate the wiring harness.
If a change of state occurs, try to isolate the origin of the incident.
Examination of Each Element
Disconnect the connectors and check the appearance of the clips and blades and their crimping (no crimping
on the insulating part).
Check that the clips and blades are properly engaged in the receptacles.
Ensure that there is no rebounding of clips or blades at the time of connection.
Check the contact pressure of the clips using a suitable model blade.
Resistance Control
Test the continuity of the lines in their entirety, then section by section.
Try to create a short-circuit to earth, on the + 12 V or with another wire.
If a DTC is detected, repair or replace the wiring.
SAFETY INSTRUCTIONS
All work on components requires that the safety rules be obeyed to prevent damage or injury:
●
Make sure the battery is properly charged to avoid damaging the ECM with a low charge.
●
Use the proper tools.
Cleanliness instructions which must be followed when working on the high-pressure direct injection system:
Risks Relating to Contamination:
The system is very sensitive to contamination. The risks caused by the introduction of contamination are damage to or destruction of the high-pressure injection system and the engine, seizing or incorrect sealing of a
component.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles a few microns in size) get into the system during dismantling or into the circuits via the fuel unions.
The cleanliness guidelines must be applied from the filter through to the injectors.
●
What are the sources of contamination?
Contamination is caused by:
–
Metal or plastic chips
–
Paint
–
Fibres from cardboard, brushes, paper, clothing, cloths
–
Foreign bodies such as hair
–
Ambient atmosphere, etc.
WARNING:
Before working on the injection system, ensure that the system pressure is nearing 0 bar.
CAUTION:
it is not possible to clean the engine using a high-pressure washer because of the risk of damaging
the connections. In addition, moisture may collect in the connectors and cause electrical connection
malfunctions.
Instructions to Be Followed before Any Work is Carried Out on The Injection System:
●
Ensure that you have the plugs for the unions to be opened (bag of plugs available from the Parts Stores,
NISSAN part No:16830 BN700, Renault part No: 77 01 206 804). Plugs are to be used once only. After
EC-1632
TROUBLE DIAGNOSIS
[K9K]
●
●
use, they must be thrown away (once used they are soiled and cleaning is not sufficient to make them
reusable). Unused plugs must be thrown away.
A
Ensure that you have hermetically resealable plastic bags for storing removed parts. There is less risk of
parts stored in this way being exposed to contamination. The bags must be used only once, and after use
they must be thrown away.
EC
Ensure that lint-free towelettes are used for injection pump related service purposes. The use of a normal
cloth or paper for cleaning purposes is prohibited. They are not lint-free and may contaminate the fuel circuit of the system. A lint-free cloth should only be used once.
C
Instructions to Be Followed before Opening The Fuel Circuit:
Use new thinner for each operation (used thinner contains impurities). Pour it into a clean receptacle.
For each operation, use a clean brush in good condition (the brush must not shed its bristles).
Use a brush and thinners to clean the connections to be opened.
Blow compressed air over the cleaned parts (tools, cleaned the same way as the parts, connections and injection system zone). Check that no bristles remain adhering.
Wash your hands before and during the operation if necessary.
When wearing leather protective gloves, cover them with latex gloves.
Instructions to Be Followed During The Operation:
As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.
The plugs to be used are available from the Parts Stores. They must not, under any circumstances, be reused.
Close the resealable bag, even if it has to be reopened shortly afterwards. The ambient atmosphere carries
impurities.
All components removed from the injection system must be stored in a hermetically sealed plastic bag once
the plugs have been inserted.
The use of a brush, thinner, bellows, sponge or normal cloth is strictly forbidden once the circuit has been
opened.
These items are likely to allow contaminants to enter the system.
A new component replacing an old one must not be removed from its packaging until it is to be fitted to the
vehicle.

ECM REPLACEMENT, PROGRAMMING OR REPROGRAMMING OPERATION
Following items can be (re)programmed via the DLC using the CONSULT-II.
●
System configuration
●
Injector adjustment value
Before replacing the ECM in after-sales operations, the following data must be readout using CONSULT-II:
●
The injector adjustment values to be noted to appropriate paper or CONSULT-II copying function.
NOTE:
The injector adjustment value for each fuel injector must be entered manually after the ECM has been
replaced or (re)programmed by reading the injector adjustment value on each fuel injector.
IMPORTANT: It is not possible to test an ECM from the parts stores because it cannot be fitted to any other
vehicle.
REPLACING THE INJECTORS
NOTE:
The injector adjustment value is a calibration made on each fuel injector in the factory in order to adjust its flow
precisely.
These injector adjustment values are written on a label affixed to each fuel injector then entered into the ECM
which then controls each fuel injector taking into account its individual manufacturing variations.
When replacing one or more fuel injectors, the parameters of the fuel injector output concerned must be modified. The system can be configured using the CONSULT-II.

TEST 8: HIGH-PRESSURE CIRCUIT LEAK CHECK
NOTE:
Certain malfunctions make it impossible to carry out this test, deal with them first.
There is a command that performs a leak test on the high-pressure circuit when the engine is running.
This command can detect a leak on the high-pressure circuit if a union is improperly fitted or bolted, but cannot
detect a small leak if a union is not torque tightened.
This command can only be used if the engine temperature is above 60°C.
Perform “HIGH PRESS CIRC LEAK T” in ACTIVE TEST mode, the engine will automatically carry out one
cycle of 4 accelerations to raise the pressure in the fuel rail and check whether there are leaks in the high
pressure circuit.
Watch out for any objects (tools, etc.) on the sides of the engine housing during the four accelerations (vibrations possible).

J
K
TEST 9: FUEL INJECTOR LEAK CHECK
NOTE:
Certain malfunctions make it impossible to carry out this test, deal with them first.
“HIGH PRESS CIRC LEAK T” in ACTIVE TEST mode also allows you to check the return volume of each fuel
injector to detect a leak inside the fuel injectors.
Tooling required:
●
It is essential to use 4 transparent pipes with an internal diameter of 4 mm and a length of approximately
50 cm.
●
4 graduated measuring cylinders.
PROCEDURE
●
Check that the engine coolant temperature is above 60°C.
●
Turn ignition switch OFF.
●
Disconnect the return pipes from the 4 fuel injectors.
●
Fit a plug in the pump venturi tube to prevent the low-pressure circuit from depriming.
●
Connect the 4 transparent pipes with an internal diameter of 4 mm and a length of 50 cm in place of the
return pipes.
●
Immerse these 4 pipes into 4 graduated measuring cylinders.
Having carried out these preparations, start the engine, then let it run for 2 minutes at idle speed.
●
Perform “HIGH PRESS CIRC LEAK T” in ACTIVE TEST mode: the engine will automatically perform one
cycle of 4 accelerations to raise the pressure in the fuel rail and measure the leaks inside the fuel injectors
in these conditions.
EC-1665
L
M
TROUBLE DIAGNOSIS
[K9K]
Once the cycle is complete, perform “HIGH PRESS CIRC LEAK T” in ACTIVE TEST mode again for the
correct reading of the return volume of each fuel injector.
At the end of both cycles, the return volume of each fuel injector should be 35 ml at maximum. If the return
volume of one of the fuel injectors is above 35 ml, replace the suspected fuel injector.
●
Disconnect the 4 transparent pipes and reconnect the fuel injector return circuit.
Watch out for any objects (tools, etc.) at the sides of the engine housing during the four cycles (vibrations possible).
●
TEST 10: FUEL INJECTOR RETURN FLOW IN STARTING PHASE
NOTE:
Certain malfunctions make it impossible to carry out this test, deal with them first.
It is useless and dangerous to engage the starter motor for more that 5 seconds.
In the event the engine does not start, only the static leak can be measured, that is the leak with the fuel injector closed, inactive and not subject to any high pressure.
Make sure that the starting circuit is working correctly (minimum speed 200 rpm).
Tooling required:
●
It is essential to use four transparent pipes with an internal diameter of 4 mm and approximately 50 cm
long.

TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT
Description
PFP:00006
A
BBS00411
Intermittent incidents may occur. In many cases, the incident 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 com- EC
plaint often do not recur on 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 indiC
cate the specific malfunctioning area.
Diagnostic Procedure

Ground Inspection
J
K
BBS00416
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.

Description
PFP:22693
A
BBS0041O
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 elec- EC
tronic 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.
C
Each control unit transmits/receives data but selectively reads required data only.

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 cylinder. 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.

BBS0044M
The camshaft position (CMP) sensor senses the retraction with camshaft to identify a particular cylinder. The camshaft position (CMP)
sensor senses the piston position.
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.

PRECAUTIONS
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BIS000T5
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.
Precautions for Procedures without Cowl Top Cover
BIS000T6
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
PIIB3706J
Precautions
BIS000T7
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.

BBS002MV
Always use a torque wrench when tightening nuts and bolts.
Unless otherwise specified, tighten nuts and bolts from inside to outside in crisscross pattern. Tighten
them gradually and evenly in two to three steps.
Always replace gasket, packing, oil seals, and O-rings with new ones.
Thoroughly wash, clean, and blow dry each part. Be sure that engine oil and coolant passages are free of
clogs.
Remove any dirt and lint on sliding and mating surfaces. Before assembly, apply ample amount of engine
oil to sliding surfaces.
If coolant was drained, bleed air from the system.
Follow the procedure below to make sure there are no fuel leaks.
Turn the ignition switch to ON (do not start engine), and with fuel pressure applied in the fuel line, check to
make sure there are no fuel leaks from the connection.
Start the engine, and at in creased speed, check again to see if there are any fuel leaks from the connection.
After assembly, start engine and increase the engine speed, then check coolant, fuel, oil, grease, and
exhaust gas for leakage.
Parts Requiring Angle Tightening
●
BBS002MU
Thoroughly inspect each part following inspection procedure, then correct or replace as necessary.
Inspect new parts in the same way, and replace if necessary.
Precautions for Assembling and Installing
●
C
Use correct special service tool in the specified position. Always pay attention to safety.
Be careful not to damage surface accuracy of mating or sliding surfaces.
To prevent foreign material from entering the engine, close openings with appropriate tape as necessary.
Arrange disassembled parts in their normal positions in order to simplify locating the cause of damage or
excessive wear and to insure correct reassembly.
The removal order of nuts and bolts should in principle move diagonally from the outside. Locations for
which order is stipulated should follow that order.

Apply liquid gasket inside bolt holes. There may be times
when application to the exterior is required, so follow those
instructions if such are found in the text.
● Attaching should be done within 5 minutes after gasket application.
● Immediately wipe off any protruding liquid gasket.
● Do nor retighten nuts and bolts after installation.
● After finishing work, wait at least 30 minutes before refilling
engine oil and coolant.

Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
Turn the crankshaft pulley two times clockwise, and make sure
tension on all pulleys is equal before doing the test.
Visually check the belts for wear, damage, and cracks on inside
and edges.
When measuring deflection, apply 98.1 N (10 kg, 22lb) at the
marked point.
PBIC1414E
PBIC1415E
CAUTION:
When measuring belt tension immediately after the belt is installed, first set the tension to the standard, rotate the crankshaft for more than two turns in order to eliminate variance in the belt tension
between pulleys, then measure and adjust tension to the standard again.

a.
Make sure the intake camshaft sprocket is in the most advanced position.
CAUTION:
Installation and removal of the intake camshaft sprocket must be done in the most advanced position for the following reasons, so make sure you follow the procedure exactly.
● The sprocket (1) and vane (camshaft coupling) (3) are
designed to spin and move within the range of a certain
angle.
● With the engine stopped the vane (3) is in the most
retarded position. It will not spin because it is locked to
the sprocket side by the internal lock pin (2).
● If the camshaft sprocket mounting bolts are turned in the
situation described above (the most retarded position),
the lock pin (2) will become damaged and cause malfunctions because of the increased horizontal load (cutting
PBIC1439E
force) on the lock pin (2).
● Put the intake camshaft sprocket in the most advance position
in the following steps.
CAUTION:
The chain tensioner must not be removed before doing this step.
NOTE:
The spinning direction in the following description is as seen from the engine front.

NOTE:
The air pressure is used to move the lock pin into the disengage
position.
● Keep applying air pressure until step “e” is completed.
PBIC1309E
CAUTION:
● Be sure not to damage the oil passage with the tip of the air gun.
● Wipe all the oil off on the top surface of the No. 1 camshaft bracket to prevent oil from being
blown with the air, and the area around the air gun should be covered with a rag when applying
air pressure. Eye protection should be worn as needed.
Turn the intake camshaft slowly counter-clockwise in direction A
(towards the intake manifold).
● Keep the air pressure on.
CAUTION:
Also be sure the wrench immobilizing the camshaft does
not come loose.
While doing the above, once you hear a click (the sound of the
internal lock pin disengaging) from inside the intake camshaft
sprocket, start turning the intake camshaft in the opposite direction, direction B (clockwise: towards the exhaust manifold) and
PBIC1440E
to the most advanced angle position.
● Keep the air pressure on.
● If there is no click, as soon as the vane (camshaft coupling) starts moving independently of the camshaft sprocket, the lock pin has become disengaged.
● If the lock pin does not become disengaged, shake the wrench immobilizing the camshaft slightly.
● If this still does not help in disengaging the lock pin, tap the intake camshaft front very lightly with a plastic hammer.
Once the vane starts to spin and then the camshaft sprocket starts to spin with the camshaft, it has
reached the most advanced position, so stop.
● Make sure the most advanced position locating intake valve
timing control advance mark (1) of vane (3) and alignment
mark (2) of sprocket (4) as shown in the figure.

The intake camshaft sprocket should be handled with the following precautions in mind.
CAUTION:
● When removing intake camshaft sprocket, using adhesive tape or equivalent, prevent vane from
rotating so that lock pin will not rejoin in the most retarded position.
● Handle it carefully, and avoid any chance of impact caused by dropping.
● Do not disassemble. (Do not loosen the four front bolts.)
NOTE:
While removing the intake camshaft sprocket, if the lock pin has been rejoined in the most retarded position, do the following to restore it.
a. Reinstall the intake camshaft sprocket to the intake camshaft and tighten the mounting bolts enough to
prevent air leaking out when the air pressure is applied later.
CAUTION:
To prevent internal lock pin from damaging, keep the torque on the mounting bolts to the minimum required to prevent air from escaping.
b. Apply the air pressure, disengage the lock pin following step 8, and turn the vane to the most advanced
position. (The timing chain need not be attached for this step.)

● 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 out or damaged. Check
the piston rings and replace if necessary.
– If the compression pressure remains at low level despite the addition of engine oil, the valves may be
malfunctioning. Check the valves for damage. Replace the valve or valve seat accordingly.

When instructed to use special service tools, use the specified tools. Always be careful to work safely,
avoid forceful or uninstructed operations.
Exercise maximum care to avoid damage to mating or sliding surfaces.
Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-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, do exactly as specified.

BBS002O0
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 the engine oil and engine coolant passages for any restriction and blockage.
Avoid damaging the sliding or mating surfaces. Completely remove foreign materials such as cloth lint or
dust. Before assembly, oil sliding surfaces well.
Release air within route when refilling after draining coolant.
Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine
stopped). Then make sure there are no leaks at fuel line connections.
After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gas for leakage.

used, be careful not to damage the mating surfaces.
PBIC0275E
LIQUID GASKET APPLICATION PROCEDURE
1.
2.
Using a scraper, remove the old liquid gasket adhering to the liquid gasket application surface and the mating surface.
● Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
PBIC0003E
3.
4.
Attach liquid gasket tube to the tube presser (SST).
Use Genuine Liquid Gasket or equivalent.
Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
● If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
PBIC2160E
EM-106
PRECAUTIONS
[HR]
As for the bolt holes, normally apply the liquid gasket inside
the holes. Occasionally, it should be applied outside the
holes. Make sure to read the text of service manual.
● Within 5 minutes of liquid gasket application, install the mating
component.
● If the liquid gasket protrudes, wipe it off immediately.
● Do not retighten mounting bolts or nut after the installation.
● Wait 30 minutes or more after installation before refilling
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe
them.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
●
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-24, "RECOMMENDED FLUIDS AND LUBRICANTS" .
●
Use procedure below to check for fuel leakage.
–
Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–
Start engine. With engine speed increased, check again for fuel leakage at connection points.
●
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
●
Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
●
Bleed air from lines and hoses of applicable lines, such as in cooling system.
●
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

The sprocket (C) and vane (camshaft coupling) (B) are
designed to spin and move within the range of a certain
angle.
With the engine stopped and the vane in the most
retarded angle, it will not spin because it is locked to the
sprocket side by the internal lock pin (A).
If the camshaft sprocket mounting bolts are turned in the
situation described above, the lock pin will become damaged and cause malfunctions because of the increased
horizontal load (cutting force) on the lock pin.

air pressure to the oil hole.
CAUTION:
● There are other oil holes in the side grooves. Do not use
the incorrect oil holes.
● Be sure not to damage the oil path with the tip of the air
gun.
● Wipe all the oil off the air gun to prevent oil from being
blown all over along with the air, and the area around the
PBIC3682E
air gun should be wiped with a rag when applying air
pressure. Eye protection should be worn as needed.
NOTE:
The air pressure is used to move the lock pin into the disengage position.
Hold the camshaft sprocket (INT) with hands, and then apply the power counterclockwise/clockwise alternatively.

leakage at connection points.
–
Start engine. With engine speed increased, check again for fuel leakage at connection points.
●
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
●
Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil
and engine coolant.
●

If the engine speed is out of the specified range, check battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
● 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 the compression pressure again.
● If some cylinder has 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, piston rings may be worn out or damaged. Check
piston rings and replace if necessary.
– If the compression pressure remains at low level despite the addition of engine oil, valves may be malfunctioning. Check valves for damage. Replace valve or valve seat accordingly.
● If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder head gasket.
9. After inspection is completed, install removed parts.
10. Start the engine, and confirm that the engine runs smoothly.

CLEANLINESS
CLEANLINESS INSTRUCTIONS WHICH MUST BE FOLLOWED WHEN WORKING ON THE HIGH PRESSURE DIRECT INJECTION SYSTEM
Risks relating to contamination
EM
The system is very sensitive to contamination. The risks caused by the introduction of contamination are:
●
Damage or destruction of the high pressure injection system and the engine,
C
●
Seizing or leaking of a component.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (particles a few microns in size) get into the system during dismantling or into the circuits via the fuel unions.
D
The cleanliness principle must be applied from the filter to the injectors.
WHAT ARE THE SOURCES OF CONTAMINATION?
Contamination is caused by:
E
●
Metal or plastic chips,
●
Paint,
●
Fibres:
F
–
Boxes,
–
Brushes,
–
Paper,
G
–
Clothing,
–
Cloths,
●
Foreign bodies such as hair,
H
●
Ambient air,
●
Etc.
I
IMPORTANT: It is not possible to clean the engine using a high pressure washer because of the risk of damaging connections. In addition, moisture may collect in the connectors and create electrical connection malfunctions.
INSTRUCTIONS TO BE FOLLOWED BEFORE ANY WORK IS CARRIED OUT ON THE INJECTION SYS- J
TEM
●
Ensure that you have the plugs for the unions to be opened (bag of plugs sold at the Parts Stores - Nissan
part No.: 16830 BN700, Renault part No.: 77 01 206 804). Plugs are to be used once only. After use, they K
must be thrown away (once used they are soiled and cleaning is not sufficient to make them reusable).
Unused plugs must be thrown away.
●
Ensure that you have hermetically resealable plastic bags for storing removed parts. Stored parts will
therefore be less subject to the risk of impurities. The bags must be used only once, and after use they L
must be thrown away.
●
Lint-free towelettes to be used for injection pump related service purpose. The use of a normal cloth or
paper for cleaning purposes is forbidden. These are not lint-free and may contaminate the fuel circuit of M
the system. Each lint-free cloth should only be used once.
INSTRUCTIONS TO BE FOLLOWED BEFORE OPENING THE FUEL CIRCUIT
●
For each operation, use new thinner (used thinner contains impurities). Pour it into a clean receptacle.
●
For each operation, use a clean brush which is in good condition (the brush must not shed its bristles).
●
Use a brush and thinners to clean the connections to be opened.
●
Blow compressed air over the cleaned parts (tools, cleaned the same way as the parts, connections and
injection system zone). Check that no bristles remain adhered.
●
Wash your hands before and during the operation if necessary.
●
When wearing leather protective gloves, cover these with latex gloves.
INSTRUCTIONS TO BE FOLLOWED DURING THE OPERATION
●
As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system. The plugs to be used are available from the Parts Stores - Nissan part No.: 16830 BN700, Renault
part No.: 77 01 206 804. They must not, under any circumstances, be reused.
●
Close the hermetically sealed bag, even if it has to be reopened shortly afterwards. Ambient air carries
contamination.
EM-229
PRECAUTIONS
[K9K]
All components of the injection system that are removed must be stored in a hermetically sealed plastic
bag once the plugs have been inserted.
●
The use of a brush, thinner, bellows, sponge or normal cloth is strictly forbidden once the circuit has been
opened. These items are likely to allow impurities to enter the system.
●
A new component replacing an old one must not be removed from its packaging until it is to be fitted to the
vehicle.

PRECAUTIONS
[K9K]
●
●
The system can inject the diesel into the engine at a pressure of up to 140,000 kPa (1,400 bar,
1,428 kg/cm2 , 20,300 psi). Before carrying out any work, check that the injector rail is no longer A
pressurized and that the fuel temperature is not too high.
You must respect the cleaning and safety advice specified in this document for any work on the
high pressure injection system.
EM
SPECIAL FEATURES
CAUTION:
●
The engine must not operate with:
–
Diesel engine fuel containing more than 10% diester,
–
Petrol, even in tiny quantities.
●
The system can inject the diesel into the engine at a pressure up to 1400 bars. Before carrying out
any work, check that the injector rail is not under pressure and that the fuel temperature is not too
high.
●
You must respect the cleaning and safety advice specified in this document for any work on the
high pressure injection system.
●
Removal of the interior of the pump and injectors is prohibited. Only the flow actuator, the fuel
temperature sensor and the venturi can be replaced.
●
For safety reasons, it is strictly forbidden to slacken a high pressure pipe union when the engine
is running.
●
It is not possible to remove the pressure sensor from the fuel rail because this may cause circuit
contamination malfunctions. If the pressure sensor fails, the pressure sensor, the rail and the five
high pressure pipes must be replaced.
●
It is strictly forbidden to remove any injection pump pulley marked number 070 575. If the pump is
being replaced, the pulley must be replaced.
●
It is forbidden to repair the wiring connecting the knock sensor (accelerometer) and the CKP sensor (engine speed sensor). If the wiring should fail, it has to be replaced with new wiring.
●
Applying 12 volts directly to any component in the system is prohibited.
●
Ultrasonic carbon removal and cleaning are prohibited.
●
Never start the engine without the battery being connected correctly.
●
It is essential to replace all the disconnected air inlet plastic pipes.
There is a 16 digit code on the injectors called individual injector correction. This code is specific to
each injector, and takes into account differences in manufacture and specifies the flow injected by
each of them.
When an injector is replaced, it is necessary to program the code of the new injector into the ECM.
Refer to EC-1625, "Injector Adjustment Value Registration" .
INSTRUCTIONS FOR HIGH PRESSURE PIPES
CAUTION:
All the high pressure pipe removed must be systematically replaced along with the clips.
TIGHTENING THE HIGH PRESSURE PIPES

CAUTION:
After any operation, check that there are no diesel leaks.
●
Reprime the circuit using the priming pump.
●
Start the engine and allow to warm up at idle speed, visually inspecting for any fuel leaks.
●
Apply tracing fluid around the high pressure connections of the pipe that has been replaced.
●
Once the engine coolant temperature is above 50°C and provided there are no malfunctions present,
carry out a road test, taking the engine speed up to 4000 rpm at least once to check that there are no
leaks.
●
Perform a visual inspection after the road test to make sure that there are no high pressure leaks.
●
Clean off the tracing fluid.
REPLACING THE INJECTORS
NOTE:
Individual injector correction is a factory calibration carried out on each injector to adjust the flow of
each one precisely, taking into account differences in manufacture.
The correction values are written on a label affixed to each injector then entered in the ECM which can then
control each injector by taking account of their differences in manufacture.
The system can be programmed “WORK SUPPORT” mode with CONSULT-II.
The correction values (16 digit code) must be replaced after replacing an injector. Refer to EC-1625, "Injector
Adjustment Value Registration" .

BBS002QP
It is very important not to scratch the gasket faces of any aluminium components.
Use suitable tool to dissolve any part of the seal which remains stuck to the metal surface.
Apply the dissolving product to the part to be cleaned, wait approximately 10 minutes, then remove it
using a wooden spatula.
Wear gloves while carrying out this operation.
Do not allow this dissolving product to drip on to the paintwork.
Great care should be taken when performing this operation, to prevent foreign objects from entering the pipes taking oil under pressure to the camshafts (pipes in both the cylinder head and its
cover) and the oil return pipes.
Failure to follow these instructions could lead to the blocking of the oilways, resulting in rapid and
serious damage to the engine.

●
When installing exhaust pipe assembly, temporarily tighten nuts on the exhaust manifold side mounting
bolts and vehicle side mounting nuts. After making sure there is no unusual tension on each part, tighten
nuts and bolts to the specified torque.
●
Be careful not to twist or apply excess tension in any direction when installing mounting rubbers.
●
Because thickness is different between center muffler rear side mounting rubber and main muffler side
mounting rubbers, install thick mount rubber at main muffler side.
●
Install seal bearing unit in the following procedures.
●
When installing heated oxygen sensor 2, use heated oxygen sensor wrench (special service tool:
KV10117200).
CAUTION:
● Do not apply impact while handing.
● Do not use heated oxygen sensor 2 after being dropped on a solid concrete floor, from a height
of 0.5 m (1.6 ft) or higher. Replace it with a new one.
● Do not tighten heated oxygen sensor 2 to a torque larger than specified. Excess tightening may
result in damage of heated oxygen sensor 2, causing MI to turn ON.
● when using heated oxygen sensor wrench (special service tool: KV10117200), tighten to the
middle of specified torque because length of tool may induce slight indication increase. Do not
tighten to the maximum specified torque.

safe area.
CAUTION:
●
Use gasoline required by the regulations for octane number.
Refer to GI-5, "Precautions for Fuel" .
●
Before removing fuel line parts, perform the following procedures:
–
Release fuel pressure from the fuel lines. Refer to EC-860, "FUEL PRESSURE RELEASE" (with
EURO-OBD) or EC-1281, "FUEL PRESSURE RELEASE" (without EURO-OBD).
–
Disconnect the battery cable from the negative cable.
●
Always replace O-rings and clamps with new ones.
●
Do not kink or twist tubes when they are being installed.
●
Perform work on level place.
●
Do not tighten hose clamps excessively to avoid damaging hoses.
●
After connecting fuel tube quick connectors, make sure quick connectors are secure.
Ensure that connector and resin tube do not contact any adjacent parts.
●
After installing tubes, make sure there is no fuel leakage at connections in the following steps.
–
Apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped). Then check
for fuel leaks at connections.
–
Start engine and rev it up and check for fuel leaks at connections.
●
Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used,
the “MIL” may come on.
●
For servicing “Evaporative Emission System” parts, refer to EC-823, "EVAPORATIVE EMISSION
SYSTEM" (with EURO-OBD) or EC-1257, "EVAPORATIVE EMISSION SYSTEM" (without EUROOBD).

BES0002F
Recommended fluid is brake fluid “Nissan Genuine Brake Fluid
or DOT 3 or DOT4 (US FMVSS No.116)”.
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.
Use flare nut wrench when removing flare nuts, and use a flare
nut torque wrench when tighten flare nuts.
Always tighten brake lines to the specified torque when installing.

When installing rubber bushings, final tightening must be carried out under unladen conditions with tyres
on flat, level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare
tyre, jack, and hand tools should be unloaded.
After installing the removed suspension parts, always check wheel alignment and adjust if necessary.
Replace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.

BAS0002E
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.

NATS will immobilize the engine if someone tries to start it without the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.
●
When 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 NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), CONSULT-II hardware and CONSULT-II NATS software is necessary.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULTII operation manual, NATS.
Therefore, CONSULT-II NATS software (program card and operation manual) must be kept strictly confidential to maintain the integrity of the anti-theft function.
●
When servicing NATS (trouble diagnoses, system initialization and additional registration of other 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 NATS.
●
When failing to start the engine first time using the key of 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.

In some wiring diagrams, two kinds of lines, representing wires, with different weight are used.
●
A line with regular weight (wider line) represents a “detectable
line for DTC (Diagnostic Trouble Code)”. A “detectable line for
DTC” is a circuit in which ECM can detect its malfunctions with
the on board diagnostic system.
●
A line with less weight (thinner line) represents a “non-detectable line for DTC”. A “non-detectable line for DTC” is a circuit in
which ECM cannot detect its malfunctions with the on board

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

●
Water intrusion
●
Electrical load
●
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.
GI-26
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
UNDER SEATING AREAS
GI
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
pinching.
B
Heat Sensitive
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
E
SGI842
F
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.
G
H
I
SGI843
Water Intrusion
J
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.
K
L
M
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
GI-27
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
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.
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.
GI-28
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
VOLTAGE CHECK METHOD
To help in understanding the diagnosis of open circuits please refer to the previous schematic.
GI
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.
●
Connect one probe of the DMM to a known good ground.
B
●
Begin probing at one end of the circuit and work your way to the other end.
●
With SW1 open, probe at SW1 to check for voltage.
voltage; open is further down the circuit than SW1.
C
no voltage; open is between fuse block and SW1 (point A).
●
Close SW1 and probe at relay.
voltage; open is further down the circuit than the relay.
D
no voltage; open is between SW1 and relay (point B).
●
Close the relay and probe at the solenoid.
voltage; open is further down the circuit than the solenoid.
E
no voltage; open is between relay and solenoid (point C).
Any powered circuit can be diagnosed using the approach in the previous example.

RESISTANCE CHECK METHOD
●
Disconnect the battery negative cable and remove the blown fuse.
●
Disconnect all loads (SW1 open, relay disconnected and solenoid disconnected) powered through the
fuse.
●
Connect one probe of the DMM to the load side of the fuse terminal. Connect the other probe to a known
good ground.
●
With SW1 open, check for continuity.
continuity; short is between fuse terminal and SW1 (point A).
no continuity; short is further down the circuit than SW1.
●
Close SW1 and disconnect the relay. Put probes at the load side of fuse terminal and a known good
ground. Then, check for continuity.
continuity; short is between SW1 and the relay (point B).
no continuity; short is further down the circuit than the relay.
●
Close SW1 and jump the relay contacts with jumper wire. Put probes at the load side of fuse terminal and
a known good ground. Then, check for continuity.
continuity; short is between relay and solenoid (point C).
no continuity; check solenoid, retrace steps.
VOLTAGE CHECK METHOD
●
Remove the blown fuse and disconnect all loads (i.e. SW1 open, relay disconnected and solenoid disconnected) powered through the fuse.
●
Turn the ignition key to the ON or START position. Verify battery voltage at the battery + side of the fuse
terminal (one lead on the battery + terminal side of the fuse block and one lead on a known good ground).
●
With SW1 open and the DMM leads across both fuse terminals, check for voltage.
voltage; short is between fuse block and SW1 (point A).

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.
GI-30
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
If repairs are needed always use wire that is of the same or larger gauge.
GI
MEASURING VOLTAGE DROP — ACCUMULATED METHOD
●
Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the
DMM should be closer to power and the negative lead closer to ground.
●
Operate the circuit.
●
The DMM will indicate how many volts are being used to “push” current through that part of the circuit.
Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.
B
C
D
E
F
G
H
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.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
BIS000MM
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.

BIS000MO
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.
GW-3
PRECAUTIONS
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.

While the urethane adhesive is curing, open a door window. This will prevent the glass from being forced
out by passenger compartment air pressure when a door is closed.
●
The fastener and the molding must be installed securely so that it is in position and leaves no gap. Install
the moldings in order of lower to upper corner, connect joint, and then corner to center.
●
Inform the customer that the vehicle should remain stationary until the urethane adhesive has completely
cured (preferably 24 hours). Curing time varies with temperature and humidity.
WARNING:
●
Keep heat and open flames away as primers and adhesive are flammable.
●
The materials contained in the kit are harmful if swallowed, and may irritate skin and eyes. Avoid
contact with the skin and eyes.
●
Use in an open, well ventilated location. Avoid breathing the vapors. They can be harmful if
inhaled. If affected by vapor inhalation, immediately move to an area with fresh air.
●
Driving the vehicle before the urethane adhesive has completely cured may affect the performance of the windshield in case of an accident.
CAUTION:
●
Do not use an adhesive which is past its usable term. Shelf life of this product is limited to six
months after 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.
●
Do not leave primers or adhesive cartridge unattended with their caps open or off.
●
The vehicle should not be driven for at least 24 hours or until the urethane adhesive has completely cured. Curing time varies depending on temperature and humidity. The curing time will
increase under lower temperature and lower humidity.
●

CAN Communication
BIS000MU
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.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BIS000TY
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.
Precautions
BIS000TZ
Disconnect both battery cables in advance.
Disconnect air bag system line 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.

●
CAN communication line is open. (CAN-H, CAN-L, or both)
CAN communication line is shorted. (Ground, between CAN lines, or other harnesses)
The areas related to CAN communication of unit is malfunctioning.
WHEN A MALFUNCTION IS DETECTED EXCEPT CAN COMMUNICATION SYSTEM
●
●
●
Removal and installation of parts: When the units that perform CAN communication or the sensors related
to CAN communication are removed and installed, malfunction may be detected (or DTC other than CAN
communication may be detected).
Fuse blown out (removed): CAN communication of the unit may be stopped at such time.
Low voltage: If the voltage decreases because of battery discharge when ignition switch is ON, malfunction may be detected by self-diagnosis according to the units.

CAN COMMUNICATION
System Description
PFP:23710
A
BKS0014C
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”
A
BKS001CE
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.

Never work with wet hands.
Xenon headlamp includes 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.
LT-5
M
PRECAUTIONS
●
●
●
●
●
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
H
BKS001CI
The 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 signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the
IPDM E/R (intelligent power distribution module engine room) via the CAN communication. The CPU (central
processing unit) located in the IPDM E/R controls the headlamp high and headlamp low relay coils. These
relays, when energized, direct power to the respective headlamps, which then illuminate.

HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps to illuminate.
This input signal is communicated to the IPDM E/R via the CAN communication. The CPU located in the IPDM
E/R controls the headlamp low relay coil, which when energized, directs power
●
through 15A fuse (No. 50, located in IPDM E/R)
●
through IPDM E/R terminal 48

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 signal
requesting the headlamp high beams to illuminate. This input signal is communicated to the IPDM E/R via the
CAN communication. The CPU located in the IPDM E/R controls the headlamp high relay coil, which when
energized, directs power
●
through 10A fuse (No. 43, located in IPDM E/R)
●
through IPDM E/R terminal 46
●
to headlamp RH terminal 2,
●
through 10A fuse (No. 44, located in IPDM E/R)
●

Ground is supplied
●
to headlamp RH and LH terminals 3
●
through grounds E45 (CR and HR engine models),E28 and E44.
With power and ground supplied, the high beam headlamps illuminate.
The combination meter that received the high beam request signal by BCM via the CAN communication
makes a high beam indicator lamp turn ON in combination meter.

D
EXTERIOR LAMP BATTERY SAVER CONTROL
To avoid flat battery caused by user leaving exterior lamps ON. When ignition is OFF and the driver side door
is opened, all exterior lamps will be turned OFF. If the user wants some lamps to remain ON then they must
switch these lamps OFF then ON again with the combination switch once the driver side door has been
opened. A buzzer will sound if any exterior lamps are ON with the driver side door opened and ignition OFF.
*:This setting can be changed by CONSULT-II. Refer to LT-19, "WORK SUPPORT" .
E
F
FAIL-SAFE FUNCTION
When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control. If the
fail-safe system is operating, headlamps illuminate when the ignition switch is turned from OFF to ON and
headlamps are turned off when the ignition switch is turn from ON to OFF. If the fail-safe system is operating,
headlamps does not operate when the combination switch is in any position. After CAN communication recovers normally, it also returns to normal control. (Refer to PG-18, "Fail-safe Control" .)
CAN Communication System Description
H
BKS001CJ
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.

With power and ground supplied, low beam headlamps illuminate.
High Beam Operation (When Daytime Light Does Not Operate)/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH BEAM or PASSING position, the BCM receives
input signal requesting headlamp high beams to illuminate. High beam request signal is communicated to the
IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls headlamp high
relay coil and low relay coil, which when energized, directs power
●

High beam indicator illuminates when combination meter receives input signal requesting high beam indicator
to illuminate. This is communicated to BCM across the CAN communication lines.
LT-36
HEADLAMP - DAYTIME LIGHT SYSTEM DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or AUTO position (headlamp is not illuminate) and
parking brake released, the IPDM E/R receives input request signal from BCM to turn on daytime light. This
input is communicated across the CAN communication lines. The CPU of the IPDM E/R controls the daytime
light relay coil. When energized, this relay directs power
●
through 10A fuse (No. 37, located in fuse and fusible link block)
●
through daytime light relay terminals 5 and 3
●
through headlamp RH terminals 3 and 1
●
through IPDM E/R terminal 48
●
through 15A fuse (No. 50, located in IPDM E/R)
●
through 15A fuse (No. 49, located in IPDM E/R)

●
to headlamp LH terminal 1.
Ground is supplied
●
to headlamp LH terminal 3
●
through grounds E45 (CR and HR engine models), E28 and E44.
Because the low beam headlamps are now wired in series, they operate at half illumination.
If the lighting switch is in the 1st and 2nd position, daytime light operation is canceled.

Each activation of the switch adds 30 seconds to a maximum of 2 minutes.
J
EXTERIOR LAMP BATTERY SAVER CONTROL
LT
To avoid flat battery caused by user leaving exterior lamps ON. When ignition is OFF and the driver side door
is opened, all exterior lamps will be turned OFF. If the user wants some lamps to remain ON then they must
switch these lamps OFF then ON again with the combination switch once the driver side door has been
opened. A buzzer will sound if any exterior lamps are ON with the driver side door opened and ignition OFF.
*:This setting can be changed by CONSULT-II. Refer to LT-45, "WORK SUPPORT" .
L
FAIL-SAFE FUNCTION
M
When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control. If the
fail-safe system is operating, headlamps illuminate when the ignition switch is turned from OFF to ON and
headlamps are turned off when the ignition switch is turn from ON to OFF. If the fail-safe system is operating,
headlamps does not operate when the combination switch is in any position. After CAN communication recovers normally, it also returns to normal control. (Refer to PG-18, "Fail-safe Control" .)
CAN Communication System Description
BKS001M4
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.

Automatically turns ON/OFF the parking lamps and the headlamps in accordance with ambient light.
OUTLINE
The auto light control system has an light and rain sensor inside it that detects outside brightness.
When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking lamps and the
headlamps in accordance with ambient light.
Light and rain sensor, power is supplied
●
through BCM terminal 73
●
to light and rain sensor terminal 1.
Light and rain sensor, ground is supplied
●
to light and rain sensor terminal 3
●
through grounds M21 and M66.
When ignition switch is turn to ON position and
When outside brightness is darker than prescribed level, input is supplied
●
to light and rain sensor terminal 2
●
through BCM terminal 63.
The headlamps will then illuminate. For a description of headlamp operation, Refer to LT-52, "System Description" .

Refer to LT-114, "COMBINATION SWITCH READING FUNCTION" .
FRIENDRY LIGHTING FUNCTION
Low beam headlamps will illuminate for 30 seconds when,
●
ignition switch is in OFF position,
●
lighting switch is placed in OFF position, and
●
lighting switch is placed in PASS position.
Each activation of the switch adds 30 seconds to a maximum of 2 minutes.

EXTERIOR LAMP BATTERY SAVER CONTROL
To avoid flat battery caused by user leaving exterior lamps ON. When ignition is OFF and the driver side door
is opened, all exterior lamps will be turned OFF. If the user wants some lamps to remain ON then they must
switch these lamps OFF then ON again with the combination switch once the driver side door has been
opened. A buzzer will sound if any exterior lamps are ON with the driver side door opened and ignition OFF.
*:This setting can be changed by CONSULT-II. Refer to LT-63, "WORK SUPPORT" .
CAN Communication System Description
BKS001DT
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.

BKS001EB
I
The control of the front fog lamps is dependent upon the position of the lighting switch. The lighting switch
must be in the 1ST/ 2ND position or AUTO position (headlamp is ON) for front fog lamp operation. When the
lighting switch is placed in front fog lamp switch ON position the BCM (body control module) receives input
signal requesting the front fog lamps to illuminate. When the headlamps are illuminated, this input signal is J
communicated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communication. The CPU (central processing unit) located in the IPDM E/R controls the front fog lamp relay coil. When
activated, this relay directs power to the front fog lamps.
LT
OUTLINE
Power is supplied at all times
●
to front fog lamp relay, located in IPDM E/R, and
●
to ignition relay, located in IPDM E/R, from battery directly,
●
through 20A fuse (No. 61, located in IPDM E/R),
●
through 20A fuse (No. 62, located in IPDM E/R),
●
through 40A fusible link (letter J, located in fuse, fusible link and relay box)
●
to BCM terminals 74 and 79,
●
through 10A fuse [No. 7, located in fuse block (J/B)]
●
to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied
●
to ignition relay, located in IPDM E/R, from battery directly,
●
through 10A fuse [No. 5, located in fuse block (J/B)]
●
to BCM terminal 24,
●
through 10A fuse [No. 4, located in fuse block (J/B)]
●

●
●
to IPDM E/R terminals 3 and 54
through grounds E45 (CR and HR engine models),E28 and E44.
FOG LAMP OPERATION
The front fog lamp switch is built in lighting switch. The lighting switch must be in 1ST/2ND position or AUTO
position (headlamp is ON) and front fog lamp switch must be ON position for front fog lamp operation.
With the front fog lamp switch in the ON position, the CPU located in the IPDM E/R grounds coil side of the
front fog lamp relay. Front fog lamp relay then directs power
●
through 20A fuse (No. 65, located in IPDM E/R),
●
through IPDM E/R terminal 44
●
to front fog lamp LH terminal 1,
●
through IPDM E/R terminal 43
●
to front fog lamp RH terminal 1.
Ground is supplied
●
to front fog lamp LH and RH terminals 2
●
through grounds E45 (CR and HR engine models),E28 and E44.
With power and grounds supplied, front fog lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to LT-114, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
Refer to LT-9, "EXTERIOR LAMP BATTERY SAVER CONTROL" .
FAIL-SAFE FUNCTION
When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control. If the
fail-safe system is operating, front fog lamps does not operate when the combination switch is in any position.
After CAN communication recovers normally, it also returns to normal control. (Refer to PG-18, "Fail-safe Control" .)
CAN Communication System Description
BKS001EC
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.

System Description
BKS001ES
The control of the rear fog lamps is dependent upon the position of the lighting switch. The lighting switch must
be in the 1ST/2ND position for rear fog lamp operation. When the lighting switch is placed in the rear fog lamp
position* the BCM (body control module) receives input signal requesting the rear fog lamps to illuminate.
*:Rear fog lamp switch is an auto return switch. BCM reads a change when rear fog lamp switch is operated. It
switches between ON and OFF every time when rear fog lamp switch is operated.
OUTLINE
Power is also supplied at all times
●
through 40A fusible link (letter J, located in the fuse and fusible link block),
●
to BCM terminals 74 and79,
●
through 10A fuse [No. 7, located in the fuse block (J/B)]
●
to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied
●
through 10A fuse [No. 5 located in the fuse block (J/B)]
●
to BCM terminal 24,
●
through 10A fuse [No. 4, located in the fuse block (J/B)]
●
to combination meter terminal 28.
Ground is supplied
●
to BCM terminals 2 and 70
●
to combination meter terminals 21, 22 and 23
●
through grounds M21 and M66.
REAR FOG LAMP OPERATION
The lighting switch must be in the 1ST or 2ND position for rear fog lamp operation.
With the rear fog lamp switch in the ON position, the BCM directs power
●
through BCM terminal 69
●
to rear combination lamp RH (rear fog lamp) terminal 2.
Ground is supplied
●
to rear combination lamp RH (rear fog lamp) terminal 1
●
through grounds B13,B28,B38 and B48.
With power and grounds supplied, the rear fog lamp illuminate.
The unified meter control unit that received the rear fog lamp request signal by BCM via the CAN communication makes a rear fog lamp indicator lamp turn on in combination meter.

CAN Communication System Description
BKS001ET
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.

System Description
PFP:25567
BKS0027I
COMBINATION SWITCH READING FUNCTION
Description
●
●
BCM reads combination switch (wiper) status, and controls related systems such as headlamps and wipers, according to the results.
BCM reads information for a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 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) switches are turned ON, the 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 the input terminal (INPUT 1-5) corresponding to that switch changes, the interface in the BCM
detects a voltage change, and the BCM determines that the switch is ON.
MKIB2223E
LT-114
COMBINATION SWITCH
BCM - Operation Table of Combination Switches
●
BCM reads operation status of the combination switch using combinations shown in the table below.
A
B
C
D
E
F
PKIC0420E
G
Sample 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.
H
I
J
LT
L
M
MKIB2289E
NOTE:
Each output terminal transistor operates at 20 ms intervals. Therefore, after a switch is turned ON, the electrical loads are activate with a time delay, However, this delay is too small to be detected.
LT-115
COMBINATION SWITCH
Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status
● When BCM is not in sleep status, output terminals (OUTPUT 1-5) send out ON signal every 10 ms.
2. Sleep status
● When BCM is in sleep status, BCM enters low power mode. Mean while out put terminals (OUTPUT 15) send out ON signal every 60ms, and accept only input from light switch system.

System Description

Combination switch M38
BKS001G4
The control of the parking, license plate and tail lamp operation is dependent upon the position of lighting
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 signal is communicated to
the IPDM E/R (intelligent power distribution module engine room) via the CAN communication. The CPU (central processing unit) located in the IPDM E/R controls the tail lamp relay coil. This relay, when energized,
directs power to parking, license plate and tail lamps, which then illuminate.
Power is supplied at all times
●
to ignition relay located in IPDM E/R and
●
to tail lamp relay located in IPDM E/R from battery directly,
●
through 20A fuse (No. 61, located in IPDM E/R),
●
through 20A fuse (No. 62, located in IPDM E/R),
●
through 40A fusible link (letter J, located in fuse, fusible link and relay box)
●
to BCM terminals 74 and 79.
With the ignition switch in the ON or START position, power is supplied
●
to ignition relay located in IPDM E/R, from battery directly and
●
through 10A fuse [No. 5, located in fuse block (J/B)]
●
to BCM terminal 24.
Ground is supplied
●
to BCM terminals 2 and 70,
●
through grounds M21 and M66,
●
to IPDM E/R terminals 3 and 54
●
through grounds E45 (CR and HR engine models), E28 and E44.
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if auto light system is activated), the BCM receives input
signal requesting parking, license plate and tail lamps to illuminate. This input signal is communicated to the
IPDM E/R via CAN communication. The CPU located in the IPDM E/R controls tail lamp relay coil, which when
energized, directs power
●
through 10A fuse (No. 45, located in IPDM E/R),
●
through IPDM E/R terminal 45
●
to parking lamp RH terminal 1,
●
through IPDM E/R terminal 16
●
to rear combination lamp RH (tail) terminal 5 and
●
to license plate lamp LH and RH terminals 1,
●
through 10A fuse (No. 46, located in IPDM E/R),
●
through IPDM E/R terminal 49
LT-134

FAIL-SAFE FUNCTION
When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control. If the
fail-safe system is operating, parking, license plate and tail lamps illuminate when the ignition switch is turned
from OFF to ON and parking, license plate and tail lamps are turned off when the ignition switch is turn from
ON to OFF. If the fail-safe system is operating, parking, license plate and tail lamps does not operate when the
combination switch is in any position. After CAN communication recovers normally, it also returns to normal
control. (Refer to PG-18, "Fail-safe Control" .)
CAN Communication System Description
H
BKS001G5
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.

CAN Communication System Description
BKS001H0
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.

RECOMMENDED FLUIDS AND LUBRICANTS
Engine Coolant Mixture Ratio
BLS0003O
The engine cooling system is filled at the factory with a high-quality,
year-round and extended life engine coolant. The high quality engine
coolant contains the specific solutions effective for the anti-corrosion
and the anti-freeze function. Therefore, additional cooling system
additives are not necessary.
CAUTION:
●
When adding or replacing coolant, be sure to use only
Nissan Genuine Coolant L250 or equivalent. Because L250
is premixed type coolant.
The use of other types of engine coolant may damage your
SMA089D
cooling system.
●
When checking the engine coolant mixture ratio by the coolant
hydrometer, use the chart below to correct your hydrometer reading (specific gravity) according to coolant
temperature.

PRECAUTIONS
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BJS000CW
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.
Precautions for Procedures without Cowl Top Cover
BJS000CX
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
PIIB3706J
Precautions for Working with HFC-134a (R-134a)
BJS000CY
WARNING:
●
Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If lubricant other than that specified is used, compressor malfunction is likely to occur.
●
The specified HFC-134a (R-134a) lubricant 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 lubricant from a sealed container. Immediately reseal containers of lubricant. Without proper sealing, lubricant will become moisture saturated and should not be used.
–
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and lubricant
manufacturers.
–
Do not allow lubricant (Nissan A/C System Oil Type R) to come in contact with styrofoam parts.
Damage may result.
General Refrigerant Precautions
BJS000CZ
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.
MTC-4
PRECAUTIONS
●
●
●
●
●
●
●
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.
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.

Precautions for Refrigerant Connection
BJS000D1
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
●
Expansion valve to evaporator
●
Refrigerant pressure sensor to condenser
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
●
A
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.
MTC-5
L
M
PRECAUTIONS
●
The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facilitating piping connections.
SHA815E
O-RING AND REFRIGERANT CONNECTION
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Do not confuse Orings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.

WARNING:
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:
G
When replacing or cleaning refrigerant cycle components, observe the following.
●
When the compressor is removed, store it in the same position as it is when mounted on the car.
Malfunction to do so will cause lubricant to enter the low-pressure chamber.
H
●
When connecting tubes, always use a torque wrench and a back-up wrench.
●
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 operaI
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.
●
Allow components stored in cool areas to warm to working area temperature before removing seal
MTC
caps. This prevents condensation from forming inside A/C components.
●
Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
●
Always replace used O-rings.
K
●
When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.

Precautions for Servicing Compressor
●
●
●
●
●
●
BJS000D2
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 Lubricant Quantity in Compressor” exactly. Refer to MTC-17, "Maintenance of Lubricant Quantity in Compressor" .
Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubricant, wipe it off by using a clean waste cloth moistened with thinner.
After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.
After replacing the compressor magnet clutch, apply voltage to the new one and check for usual
operation.
Precautions for Service Equipment
BJS000D3
RECOVERY/RECYCLING EQUIPMENT
Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.
ELECTRONIC LEAK DETECTOR
Be certain to follow the manufacturer’s instructions for tester operation and tester maintenance.
MTC-8
PRECAUTIONS
VACUUM PUMP
A
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pressure. So the vacuum pump lubricant 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 placed near the hoseto-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.

PRECAUTIONS
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.

●
●
●
BJS000D4
The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet
(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.
The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluorescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to pinpoint refrigerant leaks.
For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.
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.
Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis
during a 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
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.
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 system or CFC-12 (R-12) leak detector dye
in HFC-134a (R-134a) A/C system or A/C system damage may result.
The fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction
occurs.

Never mix HFC-134a (R-134a) refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or
its lubricant.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/lubricant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor malfunction will result.

BJS000D8
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 is
controlled by an externally equalized expansion valve, located inside the evaporator case.
FREEZE PROTECTION
B
C
Under usual operating conditions, when the A/C is switched ON, the compressor runs continuously, and the
evaporator pressure, and therefore, temperature is controlled by the compressor to prevent freeze up.
Refrigerant System Protection
BJS000D9
D
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.
ECM makes the A/C relay go OFF and stops the compressor when pressure on the high-pressure side
detected by refrigerant pressure sensor is over about 2,746 kPa (27.46 bar, 28.0 kg/cm2 , 398 psi), or below
about 134 kPa (1.34 bar, 1.4 kg/cm2 , 20 psi).
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 unusual level [more than 3.8 MPa (38 bar,
38.76 kg/cm2 , 551 psi)], the release port on the pressure relief valve automatically opens and releases refrigerant into the atmosphere.

TROUBLE DIAGNOSIS FOR UNUSUAL PRESSURE
Whenever system’s high and/or low side pressure(s) is/are unusual, diagnose using a manifold gauge. The
marker above the gauge scale in the following tables indicates the standard (usual) pressure range. Since the
standard (usual) pressure, however, differs from vehicle to vehicle, refer to above table (Ambient air temperature-to-operating pressure table).
Both High- and Low-pressure Sides are Too High
Gauge indication
Refrigerant cycle
Probable cause
Pressure is reduced soon
after water is splashed on
condenser.
Air suction by cooling fan is
insufficient.

Gauge indication
Refrigerant cycle
Probable cause
Upper side of condenser and
high-pressure side are hot,
however, liquid tank is not so
hot.
High-pressure tube or parts located
between compressor and condenser
are clogged or crushed.
Corrective action
High-pressure side is too high
and low-pressure side is too low.

Checking for Refrigerant Leaks
BJS000J0
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant 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 1 to 2 inches per second and no further than 1/4 inch 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
A
B
C
D
E
BJS000J1
1.
Check A/C system for leaks using the UV lamp and safety goggles [SST: J-42220] in a low sunlight area
(area without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a F
bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indicates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
G
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using refrigerant dye cleaner [SST: J-43872] to prevent
future misdiagnosis.
H
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
leak detector.
NOTE:
I
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
MTC
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.
Dye Injection

(This procedure is only necessary when recharging the system or when the compressor has seized and was
replaced.)
1.
2.
3.
4.
5.
6.
7.
Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.45 bar, 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 [SST: J-41459].
Connect the injector tool to the A/C low-pressure side service fitting.
Start engine and switch A/C ON.
When the A/C 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 manufacture’s operating instructions).
With the engine still running, disconnect the injector tool from the service fitting.
CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system
connection and proceed with the service procedures.
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 minutes to days for the dye to
penetrate a leak and become visible.

PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C electrical leak
detector (SST) or equivalent. Ensure that the instrument is calibrated
and set properly per the operating instructions.
The leak detector is a delicate device. In order to use the leak detector properly, read the operating instructions and perform any specified maintenance.
SHA705EB
1.
Position probe approximately 5 mm (3/16 in) away from point to
be checked.

MTC-94
REFRIGERANT LINES
CHECKING PROCEDURE
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 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.
3.
4.
Check if the A/C refrigerant pressure is at least 345 kPa (3.45 bar, 3.52 kg/cm2 , 50 psi) above 16°C. If
less than specification, recover/evacuate and recharge the system with the specified amount of refrigerant.
NOTE:
At temperatures below 16°C, leaks may not be detected since the system may not reach 345 kPa (3.45
bar, 3.52 kg/cm2 , 50 psi).
Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet f) to the
low-pressure side (evaporator drain hose g to shaft seal k). Refer to MTC-83, "Components" . Perform a
leak check for the following areas carefully. Clean the component to be checked and move the leak
detected probe completely around the connection/component.

Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. 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.
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.
If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
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.
Start engine.
Set the heater A/C control as follows;
A/C switch: ON
MODE door position: VENT (Ventilation)
Intake door position: Recirculation
Temperature control dial: Max. cold
Fan speed: High
Run engine at 1,500 rpm for at least 2 minutes.

REFRIGERANT LINES
10. Turn engine off and perform leak check again following steps 4
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.
11. Before connecting ACR4 to vehicle, check ACR4 gauges. No
refrigerant pressure should be displayed. If pressure is displayed, recover refrigerant from equipment lines.
12. Discharge A/C system using approved refrigerant recovery
equipment. Repair the leaking fitting or component if necessary.
13. Evacuate and recharge A/C system and perform the leak test to confirm no refrigerant leaks.
14. Perform A/C performance test to ensure system works properly.

BKS00268
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

The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temperature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

System Description
BKS0025N
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 relay via IPDM E/R control circuit.
●
IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control and
oil pressure switch signal reception, etc.
●
It controls operation of each electrical part via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R-integrated relays can be removed.
●
SYSTEMS CONTROLLED BY IPDM E/R
IPDM E/R receives a request signal from each Control unit with CAN communication. It controls each system.

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 reads necessary information only.
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
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 lamp is ON.
●
With the ignition switch OFF, the tail lamp is OFF.
●
With the ignition switch ON, the cooling fan HI operates.
●
With the ignition switch OFF, the cooling fan stops.

● CAN communication is normally performed with other control units.
● Individual unit control by IPDM E/R is normally performed.
PG-18
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
A status is changed into sleep transient status when receiving a sleep request signal from BCM while
all the systems controlled by IPDM E/R are under suspension.
Sleep transient status
● Process to stop CAN communication is activated.
● All systems controlled by IPDM E/R are stopped, when 3 seconds have elapsed after CAN communication with other control units is stopped, mode switches to sleep status.
Sleep status
● IPDM E/R operates in low power mode.
● CAN communication is stopped.
● When a change in CAN communication line is detected, mode switches to CAN communication status.
● When a change in ignition switch signal is detected, mode switches to CAN communication status.

BKS0025O
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. Modern
vehicles are equipped with many electronic control units 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.

Function of Detecting Ignition Relay Malfunction
●
●
When integrated ignition relay cannot be turned OFF and ignition switch is turned OFF, IPDM E/R turns
ON tail and parking lamps for 10 minutes. The lamps indicate ignition relay malfunction.
When a state of ignition relay having built-in does not agree with a state of Ignition switch signal input by a
CAN communication from BCM, IPDM E/R lets tail lamp relay operate.

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”
BGS0001O
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.
Caution:
●

BGS0001P
Always follow the warnings and the cautions below in disassembly procedures:
Work in a clean, dust-free place. No dustproof device is necessary.
Clean the outside of the unit before disassembly.
Clean the parts to be disassembled. Care must be taken not to allow any dirt or other foreign materials to
enter or come in contact with the parts.
Assemble the disassembled parts properly, following the order shown in the manual. If work has been
suspended in the middle of assembly, place a clean cover over the parts to prevent them from being contaminated.
Use paper towels when removing dirt and other foreign materials. Cloth shop towels can leave lint on the
cleaned parts that might affect the operation of the parts.
Clean disassembled parts with kerosene (except rubber parts), and then dry them thoroughly with an air
blower or paper towels.

Final tightening of bushings must be carried out under unladen condition with tyres on the ground. Oil will
shorten life of bushings. Be sure to wipe off any spilled oil.
“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare
tyre, jack, and hand tools should be unloaded.
After installing the removed suspension parts, always check wheel alignment and adjust if necessary.
Replace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BHS0002L
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.
Precaution for Seat Belt Service
BHS0002M
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 pretensioner connector, check the system function. Refer to SRS-18, "SRS Operation Check" .
●
Do not use disassemble buckle or seat belt assembly.
●
Replace anchor bolts if they are deformed or worn out.
●

●
When replacing seat belt assembly, use a genuine seat belt assembly.
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-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, etc.)
●
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
which the air bags are deployed.

INSPECTION OF ELR AND SEAT BELT WITH CHILD SAFETY SEAT ANCHOR SYSTEM
ELR and Seat Belt With Child Safety Seat Anchor System
●
●
●
ELR is a system which locks retractor in emergency cases such as sudden braking so that the webbing is
not pulled out any further.
Child safety seat anchor system is applied at the 3-point seat belt (outside seat) of back seat. Child safety
seat anchor system functions when webbing is completely pulled out. Webbing is locked at certain point
when retracting webbing little by little.
There are 2 inspections: static and dynamic. Use the following procedures to check retractor for normal
operation.
ELR Static Inspection
Does retractor lock and webbing stop immediately when quickly pulling webbing forward?
Inspection for Child Safety Seat Anchor System
1.
2.
3.
4.
Fully pull out webbing until “clicking” is heard.
Is “clicking” operating sound heard when retracting webbing little by little?
Is webbing locked and no longer pulled out when under tension?
Is child safety seat anchor system released when webbing is completely retracted?
ELR Dynamic Inspection
WARNING:
●
The following tests should be carried out in a safe, open place free of traffic and obstacles.
●
The tests should be carried out on a dry paved road. Never attempt the tests on wet or unpaved
road, open road, or highway. (This may cause an accident or personal injury.)
●
Driver and passenger assume retractor will not lock and prepare themselves accordingly.
1. Tighten driver and passenger seat belts.
2. Drive at approximately 16 km/h (MPH).
3. Notify passenger of a sudden stop. Driver and passenger prepare themselves for the possibility of retractor not locking. Then, driver fully depresses the brake pedal to stop suddenly.
4. While car stops, confirm if retractor is locked and webbing is not pulled out any more. Check for only
retractor part if it is not locked.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
BKS000TY
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.

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.

C
METHODS OF PREVENTING OVER-DISCHARGE
D
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”.
E
F
G
MEL040F
●
H
When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal. (If the vehicle has
an extended storage switch, turn it off.)
I
J
SC
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.

M
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.
SC-5
BATTERY
●
●
Remove the cell plug using a suitable tool.
Add distilled water up to the MAX level.
MEL043F
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.
SEL709E
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Convert into specific gravity at 20°C (68°F).
Example:
●
When electrolyte temperature is 35°C (95°F) and specific gravity
of electrolyte is 1.230, converted specific gravity at 20°C (68°F)
is 1.240.
●
When electrolyte temperature is 0°C (32°F) and specific gravity
of electrolyte is 1.210, converted specific gravity at 20°C (68°F)
is 1.196.

PRECAUTIONS
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BIS000U4
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.
Precautions
BIS000U5
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.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
A
BHS0002S
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.

BHS0002T
●
●
●
●
●
●
●
G
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch “OFF”, disconnect battery ground cable and wait at least 3
minutes.
For approximately 3 minutes after the cables is removed, it is still possible for the air bag and seat belt SRS
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the
I
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or 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 J
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 place front side air bag module standing with stud bolt side setting bottom.
K
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.

●
Outputs optimum assist torque signal to motor by steering wheel turning force
(sensor signal) from torque sensor and vehicle speed signal from CAN communication.
●
Reduces output signals to motor and protects motor and EPS control unit when
using power steering continuously and excessively.
●
Under unusual conditions of electric system, fail-safe function starts, output signal to motor is turned off, and then changes to manual steering. EPS warning
lamp turns on to indicate system error.
●
Controls communication with other control units by using CAN communication.
●
Allows system diagnosis with CONSULT-II
●
Produces assist torque by control signal from EPS control unit.
●
Detects steering wheel turning force and outputs sensor signal to EPS control
unit.
●
Increases motor-produced assist torque by worm gear and transmits it to column
shaft.
●
Turns on when fail-safe function operates, and indicates manual steering state.
●

TROUBLE DIAGNOSIS
How to Perform Trouble Diagnosis
PFP:00004
BGS0002Z
BASIC CONCEPT
●
●
The most important point to perform trouble diagnosis is to understand systems (control and mechanism)
in vehicle thoroughly.
It is also important to clarify customer complaints before inspection.
First of all, reproduce symptom, and understand it fully.
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptom by driving vehicle with
customer.
CAUTION:
Customers are not professionals. Do not assume “maybe
customer means...” or “maybe customer mentioned this
symptom”.
SEF234G
●
●
●
It is essential to check symptoms right from beginning in order to
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptom based on interview with customer and past examples.
Do not perform inspection on ad hoc basis. Most intermittent
malfunctions are caused by poor contacts. In this case, it will be
effective to shake suspected harness or connector by hand.
When repairs are performed without any symptom check, no
one can judge if malfunction has actually been eliminated.
After diagnosis, make sure to perform “ERASE MEMORY”.
Refer to STC-11, "Erase Memory" .
Always read “GI General Information” to confirm general precautions. Refer to GI-4, "General Precautions" .

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. Refer to LAN-21, "CAN
COMMUNICATION" .

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BES00038
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.

WHEEL BALANCE ADJUSTMENT
If a tyre 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 road wheels.
1. Set road wheel on wheel balancer using the center hole as a guide. Start the tyre balance machine.
2. When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with F
a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
G
● 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.
Indicated unbalance value × 5/3 = balance weight to be installed
H

HIGH SPEED WIPER OPERATION
When front wiper switch is placed in HI position, BCM reads combination switch condition (Refer toWW-8,
"COMBINATION SWITCH READING FUNCTION" ). And BCM sends front wiper request signal (HI) to IPDM
E/R with CAN communication line. When IPDM E/R receives front wiper request signal (HI), it turns ON front WW
wiper HI/LO relay and front wiper main relay (built into IPDM E/R).
Power is supplied
●
through front wiper main relay and front wiper HI/LO relay and,

Example: For wiper intermittent dial position 1
Using combination switch reading function, BCM detects ON/OFF status of intermittent operation dial positions 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper intermittent dial position 1.
●
Intermittent operation dial position 1: ON (Continuity exists between combination switch output 3 and input
1.)
●
Intermittent operation dial position 2: ON (Continuity exists between combination switch output 5 and input
1.)
●
Intermittent operation dial position 3: ON (Continuity exists between combination switch output 4 and input
2.)
BCM determines front wiper intermittent operation delay interval from wiper intermittent dial position 1 and
vehicle speed, and sends wiper request signal (INT) to IPDM E/R.
AUTO WIPER OPERATION (MODELS WITH LIGHT AND RAIN SENSOR)
When front auto wiper switch is toggled to AUTO position (light and rain sensor equipped), BCM reads the current combination switch condition/position (refer to WW-8, "COMBINATION SWITCH READING FUNCTION" )
and change light and rain sensor into 4stages of wiper sensitivity level.
When light and rain sensor detect rain with ignition switch ON and auto wiper switch in AUTO position the front
wiper will wipe the screen.
(Light and rain sensor will not react, if no raindrop is detected.)
●
from light and rain sensor terminal 2
●
to BCM terminal 63.
BCM send wiper request signal to IPDM E/R with CAN communication line. IPDM E/R operate front wiper.
Change the wiper speed by rainfall.
The light and rain sensor sensitivity is controlled by the wiper volume switch combined with front wiper and
washer switch and BCM.
AUTO STOP OPERATION
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach stop position.
When wiper arms are not located at stop position with wiper switch OFF, power is supplied
●
from terminal 23 of the IPDM E/R
●
to front wiper motor terminal 1, in order to continue wiper motor operation at low speed.
Ground is supplied
●
to front wiper motor terminal 2
●
through body grounds E28 and E44.
When wiper arms reach stop position, front wiper motor terminals 2 and 5 are connected.
Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When BCM receives auto-stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN communication line.
IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.
MIST OPERATION
When the front wiper switch is in mist position, low speed wiper operation cycles once and then stops.
WW-6
FRONT WIPER AND WASHER SYSTEM
For additional information about wiper operation under this condition, refer to WW-5, "LOW SPEED WIPER
OPERATION" .
If the front wiper switch is held in the mist position, low speed wiper operation continues.
A
WASHER OPERATION
When front wiper switch is pulled to washer position, power is supplied
●
through combination switch terminal 13
●
to washer motor terminal 1.
Ground is supplied
●
to washer motor terminal 2
●
through combination switch terminals 11 and 12, and
●
through body grounds M21 and M66.
With power and ground supplied, the washer motor operates, and at the same time,
When the wiper switch is pulled to the WASH position for 1 second or more. BCM sends front wiper request
signal (low) to IPDM E/R with CAN communication line. And the front wiper motor operates in low speed for 3
times to clean wind shield and then an additional wiping action will occur after 3 seconds to remove the moisture appear on the glass shortly after the wash/wipe action.
FAIL-SAFE FUNCTION
If CAN communication is malfunctioning, IPDM E/R maintains the condition of just before the fail-safe status
until ignition switch is turned OFF. (If wipers operate in LO just before the fail-safe status, operating in LO continues until ignition switch turns OFF.)
Refer to PG-18, "Fail-safe Control" .

FRONT WIPER AND WASHER SYSTEM
COMBINATION SWITCH READING FUNCTION
Description
●
●
BCM reads combination switch (wiper) status, and controls related systems such as headlamps and wipers, according to the results.
BCM reads information for a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 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) switches are turned ON, the 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 the input terminal (INPUT 1-5) corresponding to that switch changes, the interface in the BCM
detects a voltage change, and the BCM determines that the switch is ON.
MKIB2223E
BCM - Operation Table of Combination Switches
●
BCM reads operation status of the combination switch using combinations shown in the table below.
PKIC0420E
WW-8
FRONT WIPER AND WASHER SYSTEM
Sample Operation: (When Wiper Switch is Turned to LOW Position)
●
●
●
When wiper switch is turned to LOW position, front wiper LOW contact in combination switch turns ON. At
this time if OUTPUT 1 transistor is activated, BCM detects that voltage changes in INPUT 3.
When BCM detects that voltage changes in INPUT 3 while OUTPUT 1 transistor is ON, it judges that front
wiper switch is in LOW position. Then BCM sends front wiper request signal (LO) to IPDM E/R using CAN
communication.
If BCM detects that voltage changes in INPUT 3 when OUTPUT 1 transistor is activated again, it recognizes that wiper switch is still in LOW position.

NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON,
electrical loads are activated with time delay. But this time delay is so short that it cannot be detected by
human senses.
I
J
Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status
● When BCM is not in sleep status, output terminals (OUTPUT 1-5) send out ON signal every 10 ms.
2. Sleep status
WW
L
M
WW-9
FRONT WIPER AND WASHER SYSTEM
●
When BCM is in sleep status, BCM enters low power mode. Mean while out put terminals (OUTPUT 15) send out ON signal every 60ms, and accept only input from light switch system.
PKIC0832E
Intermittent Operation
Wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent operation dial position 1, intermittent operation dial position 2, and intermittent operation dial position 3) and vehicle
speed signal.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

CAN Communication
BKS00113
SYSTEM DESCRIPTION
A
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.

CAUTION:
1. When the IPDM E/R is performing the fail-safe control, the front wiper may not be operated. Check if the system is not in
the fail-safe condition.
2. This phenomenon occurs when IPDM E/R judges that front wiper is locked. It stops wiper output while IPDM E/R is operating front wiper and auto stop signal does not change for at least 10 seconds.
In this state, use IPDM E/R data monitor to check if “wiper protection” item is “BLOCK”.

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 that front wipers are locked, and stops wiper output. That causes this
symptom.

CAN Communication
BKS0012Q
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.

power distribution module engine room) controls the headlamp washer relay coil. When activated this relay
L
directs power headlamp washer motor.

Power is supplied at all times
●
through 30A fusible link (letter L, located in fuse and fusible link box).
●
to headlamp washer relay terminals 1 and 3.
●
through 40A fusible link (letter J, located in fuse and fusible link box).
●
to BCM terminals 74 and 79.
●
through 20A fuse (No.61, 62, located in IPDM E/R).
●
to IPDM E/R (CPU).
When ignition switch ON or START position, power is supplied
●
to IPDM E/R (CPU), and
●
through 10A fuse [No.5, located in fuse block (J/B)]
●
to BCM terminal 24.
Ground is supplied

HEADLAMP WASHER OPERATION
When lighting switch is placed in 2nd position, BCM read combination switch condition (Refer to WW-8,
"COMBINATION SWITCH READING FUNCTION" ).
And headlamp washer switch ON, ground is supplied.
●
to BCM terminal 62, and
●
through headlamp washer switch terminal 1 and 2.
●
through body grounds M21 and M66.
BCM sends headlamp washer request signal to IPDM E/R with CAN communication line.
And IPDM E/R is grounded to headlamp washer relay terminal 2 through IPDM E/R terminal 56.
Then headlamp washer relay is energized, power is supplied.
●
through headlamp washer relay terminal 5
●
to headlamp washer motor terminal 2.
Ground is supplied.
●
to terminal 1 of headlamp washer motor
●
through body grounds E28, E44 and E45.
With power and ground supplied, the headlamp washer operates.
CAN Communication
BKS0013G
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.
CAN Communication Unit
