The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (All circuit diagrams are shown with the switches in the OFF position.) When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Point section). See the System Outline to understand the circuit operation. When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors, splice points, and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block. Wiring related to each system is indicated in each system circuit by arrows (from__, to__).

[M] : Page No. 5 LAND CRUISER / LAND CRUISER PRADO (EWD527E) B HOW TO USE THIS MANUAL [N] System Outline Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW. When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows through the rear lights warning light to TERMINAL 4 of the light failure sensor. Stop Light Disconnection Warning When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection and the warning circuit of the light failure sensor is activated. As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition SW is turned off. [O] Service Hints S6 Stop Light SW 2-1 : Closed with the brake pedal depressed L4 Light Failure Sensor 1, 2, 7-Ground : Approx. 12 volts with the stop light SW on 4, 8-Ground : Approx. 12 volts with the ignition SW at ON position 11-Ground : Always continuity [P] : Parts Location Code See Page Code See Page Code See Page C7 34 L4 36 R7 37 H17 36 R6 37 S6 35 [Q] : Relay Blocks Code 1 [R] See Page 18 Relay Blocks (Relay Block Location) R/B No.1 (Instrument Panel Brace LH) : Junction Block and Wire Harness Connector Code See Page Junction Block and Wire Harness (Connector Location) IB 20 Instrument Panel Wire and Instrument Panel J/B (Lower Finish Panel) 3C 22 Instrument Panel Wire and J/B No.3 (Instrument Panel Brace LH) [S] : Connector Joining Wire Harness and Wire Harness Code See Page Joining Wire Harness and Wire Harness (Connector Location) IE1 42 Floor Wire and Instrument Panel Wire (Left Kick Panel) BV1 50 Luggage Room Wire and Floor Wire (Luggage Room Left) [T] : Ground Points Code See Page Ground Points Location BL 50 Under the Left Center Pillar BO 50 Back Panel Center [U] : Splice Points Code I5 See Page 44 Wire Harness with Splice Points Cowl Wire Code B18 See Page 50 Wire Harness with Splice Points Luggage Room Wire 6 LAND CRUISER / LAND CRUISER PRADO (EWD527E) B [N] : Explains the system outline.

RESISTOR, TAPPED A resistor which supplies two or more different non adjustable resistance values. SWITCH, IGNITION A key operated switch with several positions which allows various circuits, particularly the primary ignition circuit, to become operational. p RESISTOR, VARIABLE or RHEOSTAT A controllable resistor with a variable rate of resistance. Also called a potentiometer or rheostat. (Reed Switch Type) SENSOR (Thermistor) A resistor which varies its resistance with temperature. SWITCH, WIPER PARK Automatically returns wipers to the stop position when the wiper switch is turned off. SENSOR, SPEED Uses magnetic impulses to open and close a switch to create a signal for activation of other components. TRANSISTOR A solidstate device typically used as an electronic relay; stops or passes current depending on the voltage applied at "base". SHORT PIN Used to provide an unbroken connection within a junction block. SOLENOID An electromagnetic coil which forms a magnetic field when current flows, to move a plunger, etc. WIRES Wires are always drawn as (1) NOT straight lines on wiring CONNECTED diagrams. Crossed wires (1) without a black dot at the junction are not joined; crossed wires (2) with a black dot or octagonal ( ) (2) SPLICED mark at the junction are spliced (joined) connections. 19 LAND CRUISER / LAND CRUISER PRADO (EWD527E) F RELAY LOCATIONS [Engine Compartment] Engine Room R/B No.1 (LHD) Engine Room R/B No.1 (RHD) Skid Control ECU with Actuator (w/o VSC) Engine Room R/B No.4 Engine Room R/B Headlight Cleaner Relay Engine Room R/B No.3 20 LAND CRUISER / LAND CRUISER PRADO (EWD527E) F [Instrument Panel] (LHD) J/B No.1 J/B No.2 Viscous Heater Amplifier Transponder Key Computer J/B No.3 Theft Deterrent ECU Skid Control ECU (w/ VSC M/T) A/C ECU (*3) A/C Amplifier (Manual A/C) Body ECU Skid Control ECU (w/ VSC A/T) Engine and ECT ECU (A/T) Engine ECU (M/T) Center Diff.

Input Signals (1) Engine coolant temp. signal circuit The water temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance which varies according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (2) Intake air temp. signal circuit The intake air temp. sensor is installed in the air flow meter and detects the intake air temp., which is input as a control signal to TERMINAL THA of the engine and ECT ECU (A/T), engine ECU (M/T). (3) RPM signal circuit The camshaft position is detected by the camshaft position sensor and is input into TERMINAL G2+ of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal is input into TERMINAL NE+ of the engine and ECT ECU (A/T), engine ECU (M/T). (4) Throttle position sensor signal circuit The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINAL VTA of the engine and ECT ECU (A/T), engine ECU (M/T). (5) Vehicle speed circuit The speed sensor detects the vehicle speed, and the signal is input into TERMINAL SP1 of the engine and ECT ECU (A/T), engine ECU (M/T) via the combination meter. (6) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine and ECT ECU (A/T), engine ECU (M/T). When the ignition SW is turned on, the voltage for engine and ECT ECU (A/T), engine ECU (M/T) start up power supply is applied through the EFI relay, to TERMINAL +B of the engine and ECT ECU (A/T), engine ECU (M/T). The current from the IGN fuse flows to TERMINAL IGSW of the engine and ECT ECU (A/T), engine ECU (M/T). (7) Intake air volume signal circuit The intake air volume is detected by the air flow meter, and is input as a control signal to TERMINAL VG of the engine and ECT ECU (A/T), engine ECU (M/T). (8) Stop light SW signal circuit The stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (9) Starter signal circuit To confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking is detected, and is input into TERMINAL STA of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (10) Engine knock signal circuit Engine knocking is detected by the knock sensor, and is input into TERMINAL KNK of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (11) A/C SW signal system The operating voltage of the A/C control assembly (Automatic A/C), A/C amplifier (Manual A/C) is detected and input in the form of a control signal to TERMINAL AC1 of the engine and ECT ECU (A/T), engine ECU (M/T). 180 LAND CRUISER / LAND CRUISER PRADO (EWD527E) 2. Control System ∗ EFI system The EFI system monitors the engine condition through the signals input from each sensors to the engine and ECT ECU (A/T), engine ECU (M/T). The control signal is sent to the engine and ECT ECU (A/T), engine ECU (M/T) TERMINALS #10, #20, #30 and #40 to operate the injector (Fuel injection). The EFI system controls the fuel injection by the engine and ECT ECU (A/T), engine ECU (M/T) in response to the driving conditions. ∗ ESA system The ESA system monitors the engine condition through the signals input from each sensors to the engine and ECT ECU (A/T), engine ECU (M/T). The best ignition timing is decided according to this data and the data memorized in the engine and ECT ECU (A/T), engine ECU (M/T). The control signal is output to TERMINALS IGT1, IGT2, IGT3 and IGT4, and these signals control the igniter to provide the best ignition timing. 3. Diagnosis System When there is a malfunction in the engine and ECT ECU (A/T), engine ECU (M/T) signal system, the malfunctioning system is recorded in the memory. The malfunctioning system can be found by reading the code displayed on the check engine warning light. 4. Fail-Safe System When a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued control based on that system. In that case, the fail-safe system either controls the system using the data (Standard values) recorded in the engine and ECT ECU (A/T), engine ECU (M/T) memory, or else stops the engine.

Input Signals (1) Engine coolant temp. signal circuit The water temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance which varies according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (2) Intake air temp. signal circuit The intake air temp. sensor is detects the intake air temp., which is input as a control signal to TERMINAL THA of the engine and ECT ECU (A/T), engine ECU (M/T). (3) RPM signal circuit The engine RPM is detected by the crankshaft position sensor and the signal is input into TERMINAL NE+ of the engine and ECT ECU (A/T), engine ECU (M/T). (4) Throttle position sensor signal circuit The throttle position sensor detects the throttle valve opening angle as a control signal, which is input into TERMINAL VTA of the engine and ECT ECU (A/T), engine ECU (M/T). (5) Vehicle speed circuit The speed sensor detects the vehicle speed, and the signal is input into TERMINAL SPD of the engine and ECT ECU (A/T), engine ECU (M/T) via the combination meter. (6) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine and ECT ECU (A/T), engine ECU (M/T). When the ignition SW is turned on, the voltage for engine and ECT ECU (A/T), engine ECU (M/T) start up power supply is applied through the EFI relay, to TERMINAL +B of the engine and ECT ECU (A/T), engine ECU (M/T). (7) Stop light SW signal circuit The stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (8) Starter signal circuit To confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking is detected, and is input into TERMINAL STA of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (9) Engine knock signal circuit Engine knocking is detected by the knock sensor, and is input into TERMINAL KNK of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (10) A/C SW signal system The operating voltage of the A/C control assembly (Automatic A/C), A/C amplifier (Manual A/C) is detected and input in the form of a control signal to TERMINAL AC1 of the engine and ECT ECU (A/T), engine ECU (M/T). 2. Control System ∗ EFI system The EFI system monitors the engine condition through the signals input from each sensors to the engine and ECT ECU (A/T), engine ECU (M/T). The control signal is sent to the engine and ECT ECU (A/T), engine ECU (M/T) TERMINAL #10 to operate the injector (Fuel injection). The EFI system controls the fuel injection by the engine and ECT ECU (A/T), engine ECU (M/T) in response to the driving conditions. ∗ ESA system The ESA system monitors the engine condition through the signals input from each sensors to the engine and ECT ECU (A/T), engine ECU (M/T). The best ignition timing is decided according to this data and the data memorized in the engine and ECT ECU (A/T), engine ECU (M/T). The control signal is output to TERMINALS IGT1, IGT2, and these signals control the igniter to provide the best ignition timing. 3. Diagnosis System When there is a malfunction in the engine and ECT ECU (A/T), engine ECU (M/T) signal system, the malfunctioning system is recorded in the memory. The malfunctioning system can be found by reading the code displayed on the check engine warning light. 4. Fail-Safe System When a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued control based on that system. In that case, the fail-safe system either controls the system using the data (Standard values) recorded in the engine and ECT ECU (A/T), engine ECU (M/T) memory, or else stops the engine. 191 LAND CRUISER / LAND CRUISER PRADO (EWD527E) Engine Control (3RZ-FE Leaded Gasoline) Service Hints EFI Relay 5-3 : Closed with the ignition SW at ON position W3 Water Temp.

Input Signals (1) Engine coolant temp. signal circuit The water temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance which varies according to the engine coolant temp. The engine coolant temp. is input into TERMINAL THW of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (2) Intake air temp. signal circuit The intake air temp. sensor is installed in the air flow meter and detects the intake air temp., which is input as a control signal to TERMINAL THA of the engine and ECT ECU (A/T), engine ECU (M/T). (3) RPM signal circuit The camshaft position is detected by the camshaft position sensor and is input into TERMINAL G+ of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal is input into TERMINAL NE+ of the engine and ECT ECU (A/T), engine ECU (M/T). (4) Throttle signal circuit The accerelator pedal position sensor detects the accerelator pedal opening angle as a control signal, which is input into TERMINALS VPA1 and VPA2 of the engine and ECT ECU (A/T), engine ECU (M/T). (5) Vehicle speed circuit The speed sensor detects the vehicle speed, and the signal is input into TERMINAL SP1 of the engine and ECT ECU (A/T), engine ECU (M/T) via the combination meter. (6) Battery signal circuit Voltage is constantly applied to TERMINAL BATT of the engine and ECT ECU (A/T), engine ECU (M/T). When the ignition SW is turned on, the voltage for engine and ECT ECU (A/T), engine ECU (M/T) start up power supply is applied through the EFI relay, to TERMINAL +B of the engine and ECT ECU (A/T), engine ECU (M/T). The current from the IGN fuse flows to TERMINAL IGSW of the engine and ECT ECU (A/T), engine ECU (M/T). (7) Intake air volume signal circuit The intake air volume is detected by the air flow meter, and is input as a control signal to TERMINAL VG of the engine and ECT ECU (A/T), engine ECU (M/T). (8) Stop light SW signal circuit The stop light SW is used to detect whether the vehicle is braking or not, and the signal is input into TERMINAL STP of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (9) Starter signal circuit To confirm whether the engine is cranking, the voltage applied to the starter motor when the engine is cranking is detected, and is input into TERMINAL STA of the engine and ECT ECU (A/T), engine ECU (M/T) as a control signal. (10) A/C SW signal system The operating voltage of the A/C control assembly (Automatic A/C), A/C amplifier (Manual A/C) is detected and input in the form of a control signal to TERMINAL AC1 of the engine and ECT ECU (A/T), engine ECU (M/T). (11) Intake air vacuum pressure signal circuit Intake air vacuum pressure is detect by the turbo pressure sensor and is input as a control signal to TERMINAL PIM of the engine and ECT ECU (A/T), engine ECU (M/T). 204 LAND CRUISER / LAND CRUISER PRADO (EWD527E) 2. Control System ∗ GLOW relay control system When the engine starts, the GLOW relay is controlled in response to engine coolant temp. At that time, the engine and ECT ECU (A/T), engine ECU (M/T) receives the signals (input signals (1, 3, 9) ), and the current is output to the TERMINALS SREL and GIND. As a result, the engine and ECT ECU (A/T), engine ECU (M/T) controls the GLOW relay and makes the glow indicator light come on. ∗ EGR control system The EGR control system detects the signals from each sensors (Input signals (1, 3, 4, 11) ), then the current is output to the TERMINAL EGR to control the VRV (EGR). ∗ A/C cut control system When the vehicle suddenly accelerates from low engine speed, this system cuts off air conditioner operation for a fixed period of time in response to the vehicle speed, throttle valve opening angle and intake manifold pressure in order to maintain acceleration performance. The engine and ECT ECU (A/T), engine ECU (M/T) receives input signals (3, 4, 5, 10, and 11), and outputs signals to TERMINAL ACT. 3. Diagnosis System When the diagnosis system, when there is a malfunctioning in the engine and ECT ECU (A/T), engine ECU (M/T) signal system, the malfunction system is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the check engine warning light. 4. Fail-Safe System When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based on the signals from that system, the fail-safe system either controls the system by using data (Standard values) recorded in the engine and ECT ECU (A/T), engine ECU (M/T) memory or else stops the engine.

Input Signals (1) Engine coolant temp. signal system The water temp. sensor detects the engine coolant temp. and has a built-in thermistor with a resistance which varies according to the engine coolant temp. Thus the engine coolant temp. is input in the form of a control signal to TERMINAL THW of the engine and ECT ECU (A/T), engine ECU (M/T). (2) Intake air temp. signal system The intake air temp. sensor is detects the intake air temp., which is input as a control signal to TERMINAL THA of the engine and ECT ECU (A/T), engine ECU (M/T). (3) RPM signal system Crankshaft position and camshaft position are detected by the crankshaft position sensor and engine speed sensor. Crankshaft position is input as a control signal to TERMINAL TDC+ of the engine and ECT ECU (A/T), engine ECU (M/T), and RPM is input to TERMINAL NE+. (4) Throttle signal system The accelerator pedal position sensor detects the accelerator pedal opening angle, which is input as a control signal to TERMINALS VPA, VPA2 of the engine and ECT ECU (A/T), engine ECU (M/T). (5) Vehicle speed signal system The speed sensor detects the vehicle speed and input a control signal to TERMINAL SP1 of the engine and ECT ECU (A/T), engine ECU (M/T) via the combination meter. (6) A/C SW signal system The operating voltage of the A/C control assembly (Automatic A/C), A/C amplifier (Manual A/C) is detected and input in the form of a control signal to TERMINAL AC1 of the engine and ECT ECU (A/T), engine ECU (M/T). (7) Battery signal system Voltage is constantly applied to TERMINAL BATT of the engine and ECT ECU (A/T), engine ECU (M/T). When the ignition SW is turned on, the voltage for engine and ECT ECU (A/T), engine ECU (M/T) start up power supply is applied through the EFI relay, to TERMINAL +B of the engine and ECT ECU (A/T), engine ECU (M/T). The current from the IGN fuse flows to TERMINAL IGSW of the engine and ECT ECU (A/T), engine ECU (M/T). (8) STA signal system To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input as a control signal to TERMINAL STA of the engine and ECT ECU (A/T), engine ECU (M/T). (9) Fuel temp. signal system The fuel temp. sensor is detects the fuel temp., which is input as a control signal to TERMINAL THF of the engine and ECT ECU (A/T), engine ECU (M/T). (10) Intake air vacuum pressure signal system Intake air vacuum pressure is detected by the turbo pressure sensor and is input as a control signal to TERMINAL PIM of the engine and ECT ECU (A/T), engine ECU (M/T). 216 LAND CRUISER / LAND CRUISER PRADO (EWD527E) 2. Control System ∗ Fuel injection volume control system The fuel injection volume control system monitors the engine conditions through the signals (Input signals (1, 2, 3, 4, 5, 9, 10) ) input from each sensors to the engine and ECT ECU (A/T), engine ECU (M/T). Engine and ECT ECU (A/T), engine ECU (M/T) has basic data and the program (Memorized in the engine and ECT ECU (A/T), engine ECU (M/T) ) and decides the most appropriate fuel injection volume, and outputs the current to the TERMINAL SPV+ of the engine and ECT ECU (A/T), engine ECU (M/T), causing the spill control valve to operate it. ∗ Fuel injection timing control system The fuel injection timing control system monitors the engine conditions through the signals (Input signals (1, 3, 4, 5, 10) ) input from each sensors to the engine and ECT ECU (A/T), engine ECU (M/T). Engine and ECT ECU (A/T), engine ECU (M/T) has basic data and the program (Memorized in the engine and ECT ECU (A/T), engine ECU (M/T) ) and decides the most appropriate fuel injection timing, and outputs the current to the TERMINAL TCV of the engine and ECT ECU (A/T), engine ECU (M/T), causing the timing control valve to operate it. ∗ GLOW relay control system When the engine starts, the GLOW relay is controlled in response to engine coolant temp. At that time, the engine and ECT ECU (A/T), engine ECU (M/T) receives the signals (Input signals (1, 3, 8) ), and the current is output to the TERMINALS SREL and GIND. As a result, the engine and ECT ECU (A/T), engine ECU (M/T) controls the GLOW relay and makes the glow indicator light come on. ∗ EGR control system The EGR control system detects the signals from each sensors (Input signals (1, 3, 4, 10) ), then the current is output to the TERMINAL EGR to control the VRV (EGR). ∗ A/C cut control system When the vehicle suddenly accelerates from low engine speed, this system cuts off air conditioner operation for a fixed period of time in response to the vehicle speed, throttle valve opening angle and intake manifold pressure in order to maintain acceleration performance. The engine and ECT ECU (A/T), engine ECU (M/T) receives input signals (3, 4, 5, 6 and 10), and outputs signals to TERMINAL ACT. 3. Diagnosis System With the diagnosis system, when there is a malfunctioning in the engine and ECT ECU (A/T), engine ECU (M/T) signal system, the malfunction system is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the check engine warning light. 4. Fail-Safe System When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based on the signals from that system, the fail-safe system either controls the system by using data (Standard values) recorded in the engine and ECT ECU (A/T), engine ECU (M/T) memory or else stops the engine. 217 LAND CRUISER / LAND CRUISER PRADO (EWD527E) Engine Control (1KZ-TE) Service Hints EFI Relay 5-3 : Closed with the ignition SW at ON position W3 Water Temp.

Thus the water temp. is input in the form of a control signal to TERMINAL THW of the engine ECU. (2) Intake air temp. signal system The intake air temp. sensor is detects the intake air temp., which is input as a control signal to TERMINAL THA of the engine ECU. (3) RPM signal system Crankshaft position and camshaft position are detected by the crankshaft position sensor and engine speed sensor. Crankshaft position is input as a control signal to TERMINAL TDC+ of the engine ECU, and RPM is input to TERMINAL NE+. (4) Throttle signal system The accelerator pedal position sensor detects the accelerator pedal opening angle, which is input as a control signal to TERMINALS VPA, VPA2 of the engine ECU. (5) Vehicle speed signal system The speed sensor detects the vehicle speed and input a control signal to TERMINAL SP1 of the engine ECU via the combination meter. (6) A/C SW signal system The operating voltage of the A/C control assembly (Automatic A/C), A/C amplifier (Manual A/C) is detected and input in the form of a control signal to TERMINAL AC1 of the engine ECU. (7) Battery signal system Voltage is constantly applied to TERMINAL BATT of the engine ECU. When the ignition SW is turned to on, voltage for engine ECU operation is applied via the EFI relay to TERMINAL +B of the engine ECU. (8) STA signal system To confirm that the engine is cranking, the voltage applied to the starter motor during cranking is detected and is input as a control signal to TERMINAL STA of the engine ECU. (9) Fuel temp. signal system The fuel temp. sensor is detects the fuel temp., which is input as a control signal to TERMINAL THF of the engine ECU. (10) Intake air vacuum pressure signal system Intake air vacuum pressure is detected by the turbo pressure sensor and is input as a control signal to TERMINAL PIM of the engine ECU. 227 LAND CRUISER / LAND CRUISER PRADO (EWD527E) Engine Control (5L-E) 2. Control System ∗ Fuel injection volume control system The fuel injection volume control system monitors the engine conditions through the signals (Input signals (1, 2, 3, 4, 5, 9, 10) ) input from each sensors to the engine ECU. Engine ECU has basic data and the program (Memorized in the engine ECU) and decides the most appropriate fuel injection volume, and outputs the current to the TERMINAL SPV+ of the engine ECU, causing the spill control valve to operate it. ∗ Fuel injection timing control system The fuel injection timing control system monitors the engine conditions through the signals (Input signals (1, 3, 4, 5, 10) ) input from each sensors to the engine ECU. Engine ECU has basic data and the program (Memorized in the engine ECU) and decides the most appropriate fuel injection timing, and outputs the current to the TERMINAL TCV of the engine ECU, causing the timing control valve to operate it. ∗ GLOW relay control system When the engine starts, the GLOW relay is controlled in response to engine coolant temp. At that time, the engine ECU receives the signals (Input signals (1, 3, 8) ), and the current is output to the TERMINALS SREL and GIND. As a result, the engine ECU controls the GLOW relay and makes the glow indicator light come on. ∗ A/C cut control system When the vehicle suddenly accelerates from low engine speed, this system cuts off air conditioner operation for a fixed period of time in response to the vehicle speed, throttle valve opening angle and intake manifold pressure in order to maintain acceleration performance. The engine ECU receives input signals (3, 4, 5, 6 and 10), and outputs signals to TERMINAL ACT. 3. Diagnosis System With the diagnosis system, when there is a malfunctioning in the engine ECU signal system, the malfunction system is recorded in the memory. The malfunctioning system can be found by reading the display (Code) of the check engine warning light. 4. Fail-Safe System When a malfunction occurs in any system, if there is a possibility of engine trouble being caused by continued control based on the signals from that system, the fail-safe system either controls the system by using data (Standard values) recorded in the engine ECU memory or else stops the engine.

light is controlled by the body ECU. This system has following features. 1. Normal Operation ∗ When one of the doors opened, the front interior light and open door warning light is turned on. When the all doors are closed, the front interior light and open warning light is turned off. ∗ When the back door opened, the rear interior light and open door warning light is turned on. When the back door is closed, the rear interior light and open warning light is turned off. 2. Illuminated Entry System ∗ When a door is unlocked through a key operation or transmitter operation, or if a door is opened or closed, the illuminated entry system turns ON the interior light and the ignition key illumination. ∗ If the ignition switch is turned to the ACC or ON position or if all doors are locked during the 15 seconds in which these lights are ON, they will immediately turn OFF.

power window system is controlled by the body ECU. This system has following features. 1. Manual Up and Down Function This function causes the window to open or close while the power window switch is being pulled halfway up or pushed halfway down. The window stops as soon as the switch is released. 2. One-Touch Auto Up and Down Function The all doors one-touch auto up and down function enables the window of front doors to be fully opened or closed at a touch of the power window switch. 3. Jam Protection Function A jam protection function automatically stops the power window and moves it downward if a foreign object gets jammed in the window during one-touch auto-up operation. 4. Remote Control Function The up and down operations of the front passenger door window and the rear door windows can be controlled by operating the power window master switch. 5. Ker-Off Operation Function The driver's door key-off operation function makes it possible to operate the power window for approximately 45 seconds after the ignition switch is turned to the ACC or LOCK position, if the front doors are not opened. ∗ When the battery terminal or fuse is disconnected, the glass position of all doors have to be reset to the initial positions, door by door, by the power window control switch in accordance with the following procedure: A) Reconnect the battery terminal or fuse. B) Turn ON the ignition switch. C) Lower the window of each door by the power window switch to open it halfway or more. D) Then move the window up by the power window switch to close it fully. Do not release the switch for at least one second after the window is fully closed.

The electronically controlled transmission, however, electrically controls the line pressure, throttle pressure, lock-up pressure and accumulator pressure etc. through the solenoid valve. The electronically controlled transmission is a system which precisely controls gear shift timing and lock-up timing in response to the vehicle's driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing, squat and gear shift shock when starting off. 1. Gear Shift Operation When driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine and ECT ECU from the water temp. sensor and the vehicle speed signal from vehicle speed sensor is input to TERMINAL SP2+ of the engine and ECT ECU. At the same time, the throttle valve opening signal from the throttle control motor and sensor is input to TERMINALS VTA1 and VTA2 of the engine and ECT ECU as throttle angle signal. Based on these signals, the engine control module selects the best shift position for the driving conditions and sends current to the ECT solenoid. 2. Lock-Up Operation When the engine and ECT ECU decides based on each signal that the lock-up condition has been met, the current flows through TERMINAL SL of the engine and ECT ECU to TERMINAL 7 of the ECT solenoid to GROUND, causing lock-up operation. 3. Stop Light SW Circuit If the brake pedal is depressed (Stop light SW on) when driving in lock-up condition, a signal is input to TERMINAL STP of the engine and ECT ECU. The engine and ECT ECU operates and cuts the current to the solenoid to release lock-up.

The electronically controlled transmission, however, electrically controls the line pressure, throttle pressure, lock-up pressure and accumulator pressure etc. through the solenoid valve. The electronically controlled transmission is a system which precisely controls gear shift timing and lock-up timing in response to the vehicle's driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing, squat and gear shift shock when starting off. 1. Gear Shift Operation When driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine and ECT ECU from the water temp. sensor and the vehicle speed signal from speed sensor is input to TERMINAL SP2+ of the engine and ECT ECU. At the same time, the throttle valve opening signal from the throttle control motor is input to TERMINALS LU+A and LU+B of the engine and ECT ECU as throttle angle signal. Based on these signals, the engine and ECT ECU selects the best shift position for the driving conditions and sends current to the ECT solenoid. 2. Lock-Up Operation When the engine and ECT ECU decides based on each signal that the lock-up condition has been met, the current flows through TERMINAL SL of the engine and ECT ECU to TERMINAL 7 of the ECT solenoid to GROUND, causing lock-up operation. 3. Stop Light SW Circuit If the brake pedal is depressed (Stop light SW on) when driving in lock-up condition, a signal is input to TERMINAL STP of the engine and ECT ECU. The engine and ECT ECU operates and cuts the current to the solenoid to release lock-up.

The electronically controlled transmission, however, electrically controls the line pressure, throttle pressure, lock-up pressure and accumulator pressure etc. through the solenoid valve. The electronically controlled transmission is a system which precisely controls gear shift timing and lock-up timing in response to the vehicle's driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing, squat and gear shift shock when starting off. 1. Gear Shift Operation When driving, the engine warm up condition is input as a signal to TERMINAL THW of the engine and ECT ECU from the water temp. sensor and the vehicle speed signal from speed sensor is input to TERMINAL SP2+ of the engine and ECT ECU. At the same time, the throttle valve opening signal from the throttle control motor is input to TERMINALS LU+A and LU+B of the engine and ECT ECU as throttle angle signal. Based on these signals, the engine and ECT ECU selects the best shift position for the driving conditions and sends current to the ECT solenoid. 2. Lock-Up Operation When the engine and ECT ECU decides based on each signal that the lock-up condition has been met, the current flows through TERMINAL SL of the engine and ECT ECU to TERMINAL 7 of the ECT solenoid to GROUND, causing lock-up operation. 3. Stop Light SW Circuit If the brake pedal is depressed (Stop light SW on) when driving in lock-up condition, a signal is input to TERMINAL STP of the engine and ECT ECU. The engine and ECT ECU operates and cuts the current to the solenoid to release lock-up.

(EWD527E) Cruise Control (1GR-FE) System Outline The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makes it possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal. 1. Set Operation When the ON-OFF SW is turned on, the system starts preparations necessary for the cruise control and turns on the indicator light in the combination meter. 2. Set Speed Control When the - SET SW is operated with the cruise control main SW turned on during travelling, the constant vehicle speed is controlled. 3. Coast Control When the - SET SW is kept turned on during cruise control travelling, the engine and ECT ECU (A/T), engine ECU (M/T) controls the throttle valve to decelerate the vehicle. Every time the - SET SW is turned on instantaneously, the vehicle speed is decelerated approximately 1.5 km/h. 4. Accel Control When the + RES SW is kept turned on during cruise control travelling, the engine and ECT ECU (A/T), engine ECU (M/T) controls the throttle valve to accelerate the vehicle. Every time the + RES SW is turned on instantaneously, the vehicle speed is accelerated approximately 1.5 km/h. 5. Resume Control When the vehicle speed is within the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, use of the + RES SW accelerates the vehicle to the speed level used before canceling the cruise control. 6. If ∗ ∗ ∗ Manual Cancel Mechanism any of the following signals is input during cruise control travelling, the cruise control is cancelled. The stop light SW is turned on. The CANCEL SW is turned on. The ON-OFF SW is turned off. 7. If ∗ ∗ ∗ Auto Cancel Function any of the following conditions is encountered, the cruise control is automatically cancelled. The stop light SW wiring is faulty or short-circuited. The vehicle speed signal is faulty. The electronically controlled throttle malfunctions. 8. Overdrive Control Function Overdrive is sometimes cut off on gradients during cruise control driving. When end of climbing gradient is determined by throttle opening degree information after overdrive is canceled, control is reset to overdrive condition after overdrive resetting timer operation. Also, when overdrive is cut off during accelerator resuming control, control is reset to overdrive condition when accelerator resuming control is finished.

injection is controlled by switch operation at hand without stepping on the acceleration pedal when driving at constant speed is desired. 1. Set Operation When the MAIN SW is turned on, the system starts preparations necessary for the cruise control and turns on the indicator light in the combination meter. 2. Set Speed Control When the - SET SW is operated with the cruise control main SW turned on during travelling, the constant vehicle speed is controlled. 3. Coast Control When - SET SW is continuously turned on, fuel injection is controlled for decreasing, which reduces the speed of vehicle. Every time the - SET SW is turned on instantaneously, the vehicle speed is decelerated approximately 1.5 km/h. 4. Accel Control When + RES SW is continuously turned on, fuel injection is controlled for increasing, which accelerates the vehicle. Every time the + RES SW is turned on instantaneously, the vehicle speed is accelerated approximately 1.5 km/h. 5. Resume Control When the vehicle speed is within the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, use of the + RES SW accelerates the vehicle to the speed level used before canceling the cruise control. 6. If ∗ ∗ ∗ ∗ Manual Cancel Mechanism any of the following signals is input during cruise control travelling, the cruise control is cancelled. The stop light SW is turned on. The CANCEL SW is turned on. The MAIN SW is turned off. The cruise control clutch SW is turn on (M/T) 7. If ∗ ∗ ∗ Auto Cancel Function any of the following conditions is encountered, the cruise control is automatically cancelled. The stop light SW wiring is faulty or short-circuited. The vehicle speed signal is faulty. Fuel injection system abnormal 8. Overdrive Control Function The overdrive control may be cancelled if the vehicle travels on the slope during cruise control travelling. After the overdrive control has been cancelled, if the vehicle speed exceeds the overdrive return speed (The set speed is minus 2 km/h, minus 1.2 mph) and it is decided that the slope is finished, the vehicle returns to the overdrive control mode again.

D Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery. D Work must be started after 90 seconds from when the ignition switch is turned to the "LOCK" position and the negative (-) terminal cable is disconnected from the battery. (The SRS is equipped with a back-up power source so that if work is started within 90 seconds from disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.) D When the negative (-) terminal cable is disconnected from the battery, the memory of the clock and audio system will be canceled. So before starting work, make a record of the contents memorized in the audio memory system. When work is finished, reset the audio systems as they were before and adjust the clock. This vehicle has power tilt and power telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function. However, it is not possible to make a record of the memory contents. So when the work is finished, it will be necessary to explain this fact tot the customer, and ask the customer to adjust the features and reset the memory. To avoid erasing the memory in each memory system, never use a back-up power supply from outside the vehicle. D Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during repairs. D Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, seat belt pretensioner, front airbag sensor assembly, airbag sensor assembly or side airbag sensor assembly directly to hot air or flames. D Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, seat belt pretensioner, front airbag sensor assembly, airbag sensor assembly and side airbag sensor assembly should be inspected. D Never use SRS parts from another vehicle. When replacing parts, replace them with new parts. D Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, seat belt pretensioner, front airbag sensor assembly, airbag sensor assembly or side airbag sensor assembly in order to reuse it. D If the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, seat belt pretensioner, front airbag sensor assembly, airbag sensor assembly or side airbag sensor assembly has been dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace them with new ones. D Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system's electrical circuits. D Information labels are attached to the periphery of the SRS components. Follow the instructions on the notices. D After work on the SRS is completed, perform the SRS warning light check. D If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair Manual. 535 LAND CRUISER / LAND CRUISER PRADO (EWD527E) SRS S24 Side Airbag Sensor Rear LH C21 Curtain Shield Airbag Squib LH S25 Side Airbag Sensor Rear RH CSL+ CSL– VUCL ESCL CSR+ CSR– 3 2 4 1 3 2 VUCR ESCR L–B GR–R Y–V Y–O Y–V Y–O 2 LG–B ICR– 1 L–W ICR+ 2 G ICL– 1 R ICL+ LG–B 1 L–Y 4 C22 Curtain Shield Airbag Squib RH 15 A 1 A 14 A 13 A 18 C 4 C 19 C 20 C 9 A 10 A 8 C 7 C CSL+ CSL– VUCL ESCL CSR+ CSR– VUCR ESCR ICL– ICL+ ICR+ ICR– E1 GSW2 D– D+ P+ P– 13 B 14 B 16 B 17 B 10 B 11 B 8 B 7 B 2 D2+ D2– P2+ P2– E2 28 B (∗3, ∗4) 23 B W–L 27 B Y A35(A), A36(B), A37(C) Airbag Sensor Assembly Y–R 3 1 D2+ D2– Y–P Y–O 4 Y–GR Y–V 1 Y–G Y–B 9 2A 2 3 4 P2+ P2– 21 B (∗3) 14 B (∗4) F/PS W–B (∗3, ∗4) W–L E10(B) Engine and ECT ECU (A/T) Engine ECU (M/T) W–B 9 2B D– D+ A39 Airbag Squib (Steering Wheel Pad) P+ P– A38 Airbag Squib (Front Passenger Airbag Assembly) BR IM IK 536 LAND CRUISER / LAND CRUISER PRADO (EWD527E) ∗ ∗ ∗ ∗ 1 2 3 4 From Power Source System (See Page 128) : w/ Side Airbag : w/o Side Airbag : 3RZ–FE Unleaded Gasoline : 1GR–FE 10A SRS D6 DLC3 20 IL SIL TC 13 W P–B 7 S28 Side Airbag Squib LH S29 Side Airbag Squib RH E P–B 5 1C W 2 Y–G SFR– 1 Y–R SFR+ 2 Y–G SFL– 1 J14 Junction Connector Y–R SFL+ B–O 5 1E E 12 A 11 A 5 C 6 C 12 B 19 B SFL+ SFL– SFR+ SFR– SIL 5 B IG2 TC A35(A), A36(B), A37(C) Airbag Sensor Assembly P18 Pretensioner LH BR–W 1 IC1 2 IM3 1 IM3 BR–W B–W 2 IC1 B–W 2 –SR 20 B BR 1 +SR 9 B BR 2 –SL 26 B W–R 1 +SL 15 B W–R Y PR– 10 C (∗1) 6 C (∗2) Y–B PR+ 9 C 5 C Y PL– 7 A 1 A Y–B PL+ 8 A 2 A 2 1 2 1 +SL –SL +SR –SR P19 Pretensioner RH A16 Airbag Sensor Front LH A17 Airbag Sensor Front RH 537 LAND CRUISER / LAND CRUISER PRADO (EWD527E) SRS B–Y G–O (RHD) P–B (RHD) G–Y P G–Y (LHD) O (LHD) 1 LBE+ 3 A (∗1) 8 A (∗2) 4 A 3 A LBE+ 6 LSP+ (LHD) O 19 A 11 A RBE+ (LHD) G–Y (LHD) G–Y 14 C 8 C 5 LSP– LSP+ B13 Buckle SW LH Seat Position Sensor RSP+ (RHD) P 1 C 4 C RSP– LA P–B 2 C 11 C (RHD) G–O (RHD) B–Y 3 B (LHD) (RHD) LSP– A35(A), A36(B), A37(C) Airbag Sensor Assembly GR–L 1 P–L 4 3 2 4 1 3 2 SSL+ SSL– VUPL ESL SSR+ SSR– S22 Side Airbag Sensor Front LH VUPR ESR LBE– 4 W–B ESR 15 C (LHD) VUPR 17 C GR SSR– 13 C P SSR+ 16 C LG ESL 18 A L–Y VUPL 16 A LG SSL– 20 A L–W SSL+ 17 A S23 Side Airbag Sensor Front RH BO 538 LAND CRUISER / LAND CRUISER PRADO (EWD527E) From Power Source System (See Page 128) B–Y 7. 5A GAUGE G–O (RHD) P–B 4 IG (RHD) G–Y 5 RSP– 8 C 19 A B15 Buckle SW RH Seat Position Sensor 6 RSP+ B–Y G–O 1 RBE+ (RHD) P–B (RHD) G–Y (RHD) R–L (RHD) RBE– SRS 4 W–B (RHD) C 9(A), C11(C) Combination Meter ∗ 1 : w/ Side Airbag ∗ 2 : w/o Side Airbag BT 539 LAND CRUISER / LAND CRUISER PRADO (EWD527E) SRS System Outline The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts. When the ignition SW is turned to ON, the current from the SRS fuse flows to TERMINAL (C) 5 of the airbag sensor assembly. If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the SRS fuse flows to TERMINALS (B) 14, (B) 16, (B) 10, (B) 8, (A) 8 (w/ side airbag) or (A) 2 (w/o side airbag) and (C) 9 (w/ side airbag) or (C) 5 (w/o side airbag) of the airbag sensor assembly to the airbag squibs and the pretensioners to TERMINALS (B) 13, (B) 17, (B) 11, (B) 7, (B) 7 (w/ side airbag) or (A) 1 (w/o side airbag) and (C) 10 (w/ side airbag) or (C) 6 (w/o side airbag) of the airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, so that current flows to the airbag squibs and the pretensioners and causes them to operate. When the side impact also exceeds a set level, the current from the SRS fuse flows to TERMINALS (A) 12, (C) 5, (A) 9 and (D) 8 of the airbag sensor assembly to the side airbag squibs and the curtain shield airbag squibs TERMINALS (A) 11, (D) 6, (A) 10 and (C) 7 of the airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, causing side airbag squibs and curtain shield airbag squibs to operate. The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver. The airbag stored inside the passenger's instrument panel is instantaneously expanded to soften the shock to the front passenger. Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger. The curtain shield airbag can ease an impact on the head of the front and rear passengers and reduce risks of injury. The pretensioners make sure of the seat belt restrainability. : Parts Location Code See Page Code 38 (*1) 42 (*3) 46 (*5) 62 (*12) 64 (*13) 66 (*14) C9 A36 B A37 C A38 P19 55 (*7) 73 (*15) 75 (*16) 76

Normal Operation The VSC system helps prevent the vehicle from slipping sideways as a result of strong front wheel skid or strong rear wheel skid during cornering. The followings are two examples that can be considered as circumstances in which the tires exceed their lateral grip limit. The VSC system is designed to help control the vehicle behavior by controlling the engine's output and the brakes at each wheel when the vehicle is under one of the conditions indicated below. ∗ When the front wheels lose grip in relation to the rear wheels (Strong front wheel skid tendency). ∗ When the rear wheels lose grip in relation to the front wheels (Strong rear wheel skid tendency). 2. Downhill Assist Control Operation The downhill assist control operation controls braking action of each wheel to help prevent out-of-balance vehicle posture when descending a steep hill or traveling at a speed exceeding the threshold of wheel gripping capability. When the downhill assist control is in operation, the brake system controls vehicle speed within the range of 5 to 7 km/h. For the downhill assist control to be operative all of the following conditions have to be met: ∗ Downhill assist control switch = ON ∗ Transfer L4 selected ∗ Vehicle speed is 5 km/h or more, but less than 25 km/h. ∗ Accelerator pedal OFF ∗ Brake pedal OFF 3. Hill-Start Support Control Operation When starting on a steep hill for ascending, the hill-start support control automatically puts the brake on momentarily - from the moment when the driver releases his foot from the brake pedal until he steps on the accelerator pedal - to help the driver start the vehicle safely and smoothly. Please bear in mind, however, that it activates the brake system for only 3 seconds. For the hill-start support control to be operative all of the following conditions have to be met: ∗ Shift position = D, 2, or L ∗ Vehicle not moving forward with some wheel(s) slipping ∗ Vehicle

Normal Operation The VSC system helps prevent the vehicle from slipping sideways as a result of strong front wheel skid or strong rear wheel skid during cornering. The followings are two examples that can be considered as circumstances in which the tires exceed their lateral grip limit. The VSC system is designed to help control the vehicle behavior by controlling the engine's output and the brakes at each wheel when the vehicle is under one of the conditions indicated below. ∗ When the front wheels lose grip in relation to the rear wheels (Strong front wheel skid tendency). ∗ When the rear wheels lose grip in relation to the front wheels (Strong rear wheel skid tendency). 2. Downhill Assist Control Operation The downhill assist control operation controls braking action of each wheel to help prevent out-of-balance vehicle posture when descending a steep hill or traveling at a speed exceeding the threshold of wheel gripping capability. When the downhill assist control is in operation, the brake system controls vehicle speed within the range of 5 to 7 km/h. For the downhill assist control to be operative all of the following conditions have to be met: ∗ Downhill assist control switch = ON ∗ Transfer L4 selected ∗ Vehicle speed is 5 km/h or more, but less than 25 km/h. ∗ Accelerator pedal OFF ∗ Brake pedal OFF 3. Hill-Start Support Control Operation When starting on a steep hill for ascending, the hill-start support control automatically puts the brake on momentarily - from the moment when the driver releases his foot from the brake pedal until he steps on the accelerator pedal - to help the driver start the vehicle safely and smoothly. Please bear in mind, however, that it activates the brake system for only 3 seconds.

This results in improved directional stability and steerability during panic braking. 1. Input Signals (1) Speed sensor signal The speed of the wheels is detected and input to TERMINALS 9, 12, 31 and 34 of the skid control ECU with actuator. (2) Stop light SW signal A signal is input to TERMINAL 10 of the skid control ECU with actuator when the brake pedal is depressed. 2. System Operation During sudden braking the skid control ECU with actuator has signals input from each sensor, which controls the current to the solenoid inside the actuator and lets the hydraulic pressure acting on each wheel cylinder escape to the reservoir. The pump inside the actuator is also operating at this time and it returns the brake fluid from the reservoir to the master cylinder, thus preventing locking of the vehicle wheels. If the skid control ECU with actuator judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current on the solenoid is controlled and the hydraulic pressure is increased. Holding of the hydraulic pressure is also controlled by the skid control ECU with actuator, by the same method as above. Pressure reduction, holding and increase are repeated to maintain vehicle stability and to improve steerability during sudden braking. Service Hints S1 Skid Control ECU with Actuator 2, 24-Ground : Always continuity 25-Ground : Approx. 12 volts with the ignition SW at ON position 10-Ground : Approx. 12 volts with the brake pedal

CRUISER / LAND CRUISER PRADO (EWD527E) Electric Modulated Air Suspension System Outline ∗ The electric modulated suspension with height control, is a system designed to maintain a constant ride height by means of an electro-pneumatic system in the rear suspension - to cope with change in load due to possible change in the number of people and/or the weight of cargo the vehicle has to carry. With three driver's-choice height-control switches on the console, the driver can set ride height to any one of the three different ride height modes (High, normal and low): "High mode" for rough terrain and "Low mode" for passenger to get on or get off, and for cargo to be loaded or unloaded. ∗ This system has five basic controls as shown below: ∗ Auto leveling control This control maintains a constant rear vehicle ride height regardless of change in load due to possible change in the number of passengers and/or the weight of cargo the vehicle has to carry. ∗ Ride height switchover control This control switches over height mode to the mode selected by the height control switch. ∗ High mode (+ 40 mm / 1.6 in.) ∗ Low mode ( - 20 mm / 0.8 in.) ∗ Speed sensing control Regardless of the initial height mode setting, "High mode" or "Low mode," this control automatically switches over vehicle height mode to the optimum "Normal mode": ∗ When the vehicle speed reaches or exceeds 30 km/h with height mode set to "High mode," or; ∗ When the vehicle speed reaches or exceeds 5 km/h with height mode set to "Low mode." ∗ Subsequent control after ignition switch off After the ignition switch is turned OFF, this control lowers the rear vehicle ride height to offset rear vehicle ride height elevation due to passengers getting off, etc. ∗ Height control OFF control Pressing the absorber control switch turns the system OFF, making it possible for the vehicle to be jacked up or towed.

ACC fuse flows to TERMINAL 6 of the shift lock control ECU. When the ignition SW is turned to ON position, the current from the ECU-IG fuse flows to TERMINAL 1 of the shift lock control ECU. 1. Shift Lock Mechanism If the brake pedal is depressed with the ignition SW set at ON (The stop light SW is on), the shift lock control ECU is activated, allowing the driver to change the shift lever to a position other than the P position. 2. Key Interlock Mechanism With the ignition SW at ON or ACC position, when the shift lever is put in P position, the current flowing from TERMINAL 12 of the shift lock control ECU to key interlock solenoid is cut off. This causes the key interlock solenoid to turn off (Lock lever disengages from LOCK position) and the ignition key can be turned from ACC to LOCK position.

LAND CRUISER PRADO (EWD527E) Moon Roof System Outline Current is always applied from the POWER fuse to TERMINAL 10 of the moon roof control ECU and motor. With the ignition SW turned on, the current flows to TERMINAL 9 of the moon roof control ECU and motor. 1. Moon Roof Open/Close Operation For moon roof operation, there are moon roof control switches: "Slide open/tilt down"; and "Slide close/tilt up." When a switch is pressed and held down for a certain period of time, one touch automatic operation takes place in accordance with the function of the switch. 2. Key-Off Operation Roof remains operable - until about 45 seconds elapse after the ignition SW is turned from ON to OFF or until the driver's seat door is opened and closed, whichever first occurs. However, if an overload reverse operation was going on at that time, the key-off operation continues until it comes to an end. 3. Overload Reverse Operation The moon roof control ECU detects jamming of the moon roof by foreign material, if occurred, from abnormal motor speed signal and reverses the moon roof operation. 4. Deflector Control Function When the roof is slid fully open, the moon roof control ECU automatically adjusts the height of deflector in accordance with the vehicle cruising speed. ∗ When the battery terminal or fuse is disconnected, the roof position has to be reset to its initial position by the moon roof control SW in accordance with the following procedure: (1) Reconnect the battery terminal or fuse. (2) Turn ON the ignition switch. (3) Operate the moon roof control SW to open the roof halfway or more. (4) Then operate the moon roof control SW to fully close the roof. Do not release the switch for at least one second after the roof is fully closed.

Pressing the power heater switch provided in the instrument panel engages the magnetic clutch causing the rotor in the viscous heater to rotate and the silicon oil to mix. With the rise of the coolant temperature caused by these factors such as the shear heat generated when the silicon oil is mixed and the engine load at this time, the viscous heater supplements the rise of heater operation temperature.

Heater Blower Operation Manual operation When the blower speed is set to a certain level using the blower control SW, the A/C control assembly sends the signals to the blower control to control the blower motor speed. Auto operation When the auto SW is pushed, the A/C control assembly sends the signals from various sensors and temperature SW to the blower control to automatically control the blower motor speed. 2. Air Inlet Control Servo Motor Control When the FRESH/RECIRC select SW is set to RECIRC, the motor in the air inlet control servo motor starts rotating to move the damper toward the RECIRC side. Since the damper position is detected by the TERMINAL TPI of the A/C control assembly, the motor is continuously rotated until the damper reaches its stop position. When the FRESH/RECIRC select SW is set to FRESH, the motor in the air inlet control servo motor starts rotating to move the damper toward the FRESH side. Since the damper position is detected by the TERMINAL TPI of the A/C control assembly, the motor is continuously rotated until the damper reaches its stop position. 3. Air Vent Mode Control Servo Motor Control When the mode select SW is pushed, the ECU in the A/C control assembly activates the air vent mode control servo motor. This causes the servo motor to rotate to the position (FACE, BI-LEVEL, FOOT, FOOT/DEF, DEF) selected using the mode select SW, and moves the damper. 4. Air Mix Control Servo Motor Control When the temperature control SW on the driver's side is pressed, the ECU in the A/C control assembly sends a signal to the air mix control servo motor on the driver's side. This signal drives the motor to reach the temperature set by the temperature control SW on the driver's side, and moves the damper. Passenger's side is operated as same as the driver's side. 5. Air Conditioning Operation The A/C control assembly receives various signals, I.E., the engine RPM from the engine and ECT ECU (A/T), engine ECU (M/T), out side air temperature signal from the A/C ambient temp. sensor and coolant temperature from the engine and ECT ECU (A/T), engine ECU (M/T), etc. When the engine is started and the A/C SW (A/C control assembly) is on, a signal is input to the A/C control assembly. As a result, the ground circuit in A/C control assembly is closed and current flows from IG1 fuse to TERMINAL 1 of the MG CLT relay to TERMINAL 2 to TERMINAL MGC of the A/C control assembly to GROUND, turning the MG CLT relay on, so that the magnetic clutch is on and the A/C compressor operates. If the A/C control assembly detects the following conditions, it stops the air conditioning: ∗ Evaporator outlet air is too low. ∗ There is a marked difference between the compressor speed and the engine speed. ∗ The refrigerant pressure is abnormally high or abnormally low. ∗ The engine speed is too low. ∗ Rapid acceleration occurs. Service Hints P2 Pressure SW 1-2 : Open with the refrigerant pressure at less than approx. 216 kpa (2.2 kgf/cm2, 31 psi) or more than approx. 3138 kpa (32 kgf/cm2, 455 psi) A21 (A), A22 (B), A23 (C)

Heater Blower Motor Operation ∗ Low speed operation When the blower SW is moved to LO position, current flows to TERMINAL C1 of the blower SW to GROUND, activating the HEATER relay. This causes the current to flow from the HEATER fuse to TERMINAL 5 of the HEATER relay to TERMINAL 3 to TERMINAL 2 of the front blower motor to TERMINAL 1 to TERMINAL 1 (LHD), 4 (RHD) of the blower resistor to TERMINAL 4 (LHD), 1 (RHD) to GROUND, causing the blower motor to rotate at low speed. ∗ Medium speed operation (Operation at M1, M2) When the blower SW is moved to M1 position, current flows to TERMINAL C1 of the blower SW to GROUND, turning the HEATER relay to switch on. This causes the current to flow from the HEATER fuse to TERMINAL 5 of the HEATER relay to TERMINAL 3 to TERMINAL 2 of the front blower motor to TERMINAL 1 to TERMINAL 1 (LHD), 4 (RHD) of the blower resistor to TERMINAL 2 (LHD), 3 (RHD) to TERMINAL 6 of the blower SW to GROUND. At this time, the blower resistance of the blower resistor is less than at low speed, so the blower motor rotates at medium low speed. When the blower SW is moved to M2 position, current flows through the motor flows from TERMINAL 1 (LHD), 4 (RHD) of the blower resistor to TERMINAL 3 (LHD), 2 (RHD) to TERMINAL 5 of the blower SW to GROUND. At this time, resistance of the blower resistor is less than at M1 position, so the blower motor rotates at medium high speed. ∗ High speed operation When the blower SW is moved to HIGH position, current flows to TERMINAL C1 of the blower SW to GROUND, turning the HEATER relay to switch on. This causes the current to flow from the HEATER fuse to TERMINAL 5 of the HEATER relay to TERMINAL 3 to TERMINAL 2 of the blower motor to TERMINAL 1 to TERMINAL 4 of the blower SW to GROUND, causing the blower motor to rotate at high speed.

LAND CRUISER / LAND CRUISER PRADO (EWD527E) Rear Air Conditioner (Automatic A/C) System Outline 1. Manual Operation When air volume is set by blower control SW within rear A/C control SW, signal is transmitted from rear A/C control SW to A/C control assembly. A/C control assembly controls power transistor, and controls the blower motor at preset air volume. 2. Auto Operation When blower control SW within rear A/C control SW is set to AUTO position, signal is transmitted from rear A/C control SW to A/C control assembly. A/C control assembly controls the power transistor based on signal from various sensors, operates the blower motor, and adjusts air volume. It should be noted that auto control applies only when blowout port of front air conditioner is positioned at FACE, and blower is turned off otherwise. 3. Temperature control Temperature control of rear air conditioner can be set up to + / -5 °C of front air conditioner temperature setting. ∗ Rear air conditioner works only when front air conditioner is operating, and only blows air when front air conditioner is off.

Heater Blower Motor Operation ∗ Low speed operation When the REAR COOL SW in the rear A/C control SW is pushed to on and the rear blower control SW is moved to LO position, current flows to TERMINAL RCOOL of the rear A/C control SW to GROUND, activating the rear A/C relay. This causes the current to flow from the RR A/C fuse to TERMINAL 5 of the rear A/C relay to TERMINAL 3 to TERMINAL 1 of the rear blower motor to TERMINAL 2 to TERMINAL 6 of the rear blower resistor to TERMINAL 3 to GROUND, causing the blower motor to rotate at low speed. ∗ Medium speed operation (Operation at M1, M2) When the REAR COOL SW in the rear A/C control SW is pushed to on and the rear blower control SW is moved to M1 position, current flows to TERMINAL RCOOL of the rear A/C control SW to GROUND, turning the rear A/C relay to switch on. This causes the current to flow from the RR A/C fuse to TERMINAL 5 of the rear A/C relay to TERMINAL 3 to TERMINAL 1 of the rear blower motor to TERMINAL 2 to TERMINAL 6 of the rear blower resistor to TERMINAL 4 to TERMINAL 3 of the rear blower control SW to GROUND. At this time, the blower resistance of the rear blower resistor is less than at low speed, so the blower motor rotates at medium low speed. When the rear blower control SW is moved to M2 position, current flows through the motor flows from TERMINAL 6 of the rear blower resistor to TERMINAL 5 to TERMINAL 4 of the rear blower control SW to GROUND. At this time, resistance of the blower resistor is less than at M1 position, so the blower motor rotates at medium high speed. ∗ High speed operation When the REAR COOL SW in the rear A/C control SW is pushed to on and the rear blower control SW is moved HIGH position, current flows to TERMINAL RCOOL of the rear A/C control SW to GROUND, turning the rear A/C relay switch on. This causes the current to flow from the RR A/C fuse to TERMINAL 5 of the rear A/C relay to TERMINAL 3 TERMINAL 1 of the rear blower motor to TERMINAL 2 to TERMINAL 6 of the rear blower resistor to TERMINAL 2 TERMINAL 1 of the rear blower control SW to GROUND, causing the blower motor to rotate at high speed. to to to to Service Hints R22 Rear Cooler Relay 5-3 : Closed with the ignition SW on and the REAR COOL SW in the rear A/C control SW on R17 Rear Cooler Amplifier 1-Ground : Approx. 12 volts with ignition SW at ON 4-Ground : Always continuity : Parts Location Code See Page 48 (LHD) A20 68 (RHD) 50 (LHD) J24 70 (RHD) 50 (LHD) J26 70 (RHD) 51 (LHD) R6 71 (RHD) Code R7 R17 R18 R19 See Page 51 (LHD) 71 (RHD) 53 (*6) 73 (*15) 53 (*6) 73 (*15) Code R20 R22 R23 See Page 53 (*6) 73 (*15) 53 (*6) 73 (*15) 53 (*6) 73 (*15) 53 (*6) 73 (*15) : Relay Blocks Code 2 See Page 23 Relay Blocks (Relay Block Location) Engine Room R/B (Engine Compartment Left) * 1 : LHD 1GR-FE * 2 : LHD 3RZ-FE * 3 : LHD 1KD-FTV * 4 : LHD 1KZ-TE * 5 : LHD 5L-E * 6 : LHD 5-Door * 7 : LHD 3-Door * 8 : LHD 8Way Power Seat * 9 : LHD Except 8Way Power Seat * 10 : RHD 1GR-FE * 11 : RHD 3RZ-FE * 12 : RHD 1KD-FTV * 13 : RHD 1KZ-TE * 14 : RHD 5L-E * 15 : RHD 5-Door * 16 : RHD 3-Door * 17 : RHD 8Way Power Seat * 18 : RHD Except 8Way Power Seat 724 LAND CRUISER / LAND CRUISER PRADO (EWD527E) : Junction Block and Wire Harness Connector Code IK 1A See Page 27 (LHD) 29 (RHD) Junction Block and Wire Harness (Connector Location) Instrument Panel Wire and Driver Side J/B (Lower Finish Panel) 32 (LHD) Instrument Panel Wire and J/B No.1 (Instrument Panel Reinforcement Left) 32 (RHD) Instrument Panel Wire and J/B No.1 (Instrument Panel Reinforcement Right) : Connector Joining Wire Harness and Wire Harness Code II2 IM4 IN3 BG1 See Page 90 (LHD) 114 (RHD) 92 (LHD) 116 (RHD) 94 (LHD) 118 (RHD) 98 (*6) 122 (*15) Joining Wire Harness and Wire Harness (Connector Location) Console Box Wire and Instrument Panel Wire (Under the Instrument Panel Brace LH) Instrument Panel Wire and Engine Room Main Wire (Right Kick Panel) Instrument Panel Wire and Floor Wire (Right Kick Panel) Floor Wire and Rear A/C Sub Wire (Right Quarter Panel Inner) : Ground Points Code IN See Page Ground Points Location 88 (LHD) Right Kick Panel 112 (RHD) Left Kick Panel 96 (*6) BT 100 (*7) 120 (*15) Right Quarter Panel Inner 124 (*16) : Splice Points Code I7 See Page 90 (LHD) 114 (RHD) Wire Harness with Splice Points Instrument Panel Wire Code B7 See Page 98 (*6) 122 (*15) Wire Harness with Splice Points A/C Sub Wire * 1 : LHD 1GR-FE * 2 : LHD 3RZ-FE * 3 : LHD 1KD-FTV * 4 : LHD 1KZ-TE * 5 : LHD 5L-E * 6 : LHD 5-Door * 7 : LHD 3-Door * 8 : LHD 8Way Power Seat * 9 : LHD Except 8Way Power Seat * 10 : RHD 1GR-FE * 11 : RHD 3RZ-FE * 12 : RHD 1KD-FTV * 13 : RHD 1KZ-TE * 14 : RHD 5L-E * 15 : RHD 5-Door * 16 : RHD 3-Door * 17 : RHD 8Way Power Seat * 18 : RHD Except 8Way Power Seat 725 LAND CRUISER / LAND CRUISER PRADO (EWD527E) Cooler Box From Power Source System (See Page 128) 1 ∗ 1 : Automatic A/C ∗ 2 : Manual A/C 10A IG1 NO. 2 10A ECU–B C18 Cool Box SW 2 7 IK 4 6 W–R I7 4 1B 4 IB 3 1B 4 IL II2 W–R Y I12 R GR–L GR–L LG–R 9 W–R GR–L 1 GR 3 W–L 2 2 4 IK1 2 IK1 B 2 SG LED TE 3 1 ILL +B C16 Cool Box Amplifier BLW GND CBT 10 6 9 4 8 W J26 Junction Connector 7 SW Y–R GR–L B 5 W–L IG W–R B W–R GR–L GR–L II2 GR–L 17 W–B BR–Y 6 IK1 5 IK1 GR W–L 1 IK1 I12 J26 Junction Connector 19 II2 BR–Y A 3 20 B BR–Y W–B A II2 2 IF1 Noise Filter (In–Line) C17 Cool Box Motor 2 4 (∗1) 28 C–BOXIN W COOL BR–Y BR–Y M W–B 1 (∗2 Except 1GR–FE) B L–R I12 2 W–B Diode (In–Line) W–L C19 Cool Box Thermistor L–R 4A Fuse (In–Line) B I12 W A J15 Junction Connector A20 A/C Amplifier A21 A/C Control Assembly (w/o Navigation System) A/C ECU (w/ Navigation System) IL 726 LAND CRUISER / LAND CRUISER PRADO (EWD527E) System Outline When cooler SW is turned on, signal enters TERMINAL 5 of cooler box amplifier.
