HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles bydividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the powersource is received from the battery as far as each ground point. (All circuitdiagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuitwhere the problem was detected (see System Circuit section), the power sourcesupplying power to that circuit (see Power Source section), and the ground points(see Ground Point section). See the System Outline to understand the circuitoperation.
When the circuit operation is understood, begin troubleshooting of the problemcircuit to isolate the cause. Use Relay Location and Electrical Wiring Routingsections to find each part, junction block and wiring harness connectors, wiringharness and wiring harness connectors and ground points of each system circuit.Internal wiring for each junction block is also provided for better understanding ofconnection within a junction block.Wiring related to each system is indicated in each system circuit by arrows(from__, to__). When overall connections are required, see the Overall ElectricalWiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop lamp SW.When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flowsthrough the rear lights warning light to TERMINAL 4 of the light failure sensor.
Stop Light Disconnection WarningWhen the ignition SW is turned on and the brake pedal is pressed (Stop lamp SW on), if the stop light circuit is open, the currentflowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects thedisconnection 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 lightswarning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warningcircuit on and holds the warning light on until the ignition SW is turned off.

VOLTAGE CHECK
(a) Establish conditions in which voltage is present at the checkpoint.
Example:[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (SW 2 off)
(b) Using a voltmeter, connect the negative lead to a good groundpoint or negative battery terminal, and the positive lead to theconnector or component terminal.This check can be done with a test light instead of a voltmeter.
CONTINUITY AND RESISTANCE CHECK
(a) Disconnect the battery terminal or wire so there is no voltagebetween the check points.
(b) Contact the two leads of an ohmmeter to each of the checkpoints.
If the circuit has diodes, reverse the two leads and checkagain.When contacting the negative lead to the diode positive sideand the positive lead to the negative side, there should becontinuity.When contacting the two leads in reverse, there should be nocontinuity.
(c) Use a volt/ohmmeter with high impedance (10 kΩ/Vminimum) for troubleshooting of the electrical circuit.

FINDING A SHORT CIRCUIT
(a) Remove the blown fuse and disconnect all loads of the fuse.
(b) Connect a test light in place of the fuse.
(c) Establish conditions in which the test light comes on.
Example:[A] – Ignition SW on[B] – Ignition SW and SW 1 on[C] – Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 off (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while watching thetest light.The short lies between the connector where the test lightstays lit and the connector where the light goes out.
(e) Find the exact location of the short by lightly shaking theproblem wire along the body.
CAUTION:(a) Do not open the cover or the case of the ECU unless
absolutely necessary. (If the IC terminals are touched,the IC may be destroyed by static electricity.)
(b) When replacing the internal mechanism (ECU part) ofthe digital meter, be careful that no part of your body orclothing comes in contact with the terminals of leadsfrom the IC, etc. of the replacement part (spare part).

The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makesit possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal.
1. Set OperationWhen the CRUISE SW is turned on and the SET SW is pushed with the vehicle speed within the set limit (Approx. 40 km/h,25 mph to 200 km/h, 124 mph), a signal is input to TERMINAL CCS of the engine control module, and the vehicle speed atthe time the SET SW is released is memorized in the ECU as the set speed.
2. Set Speed ControlDuring cruise control driving, the ECU compares the set speed memorized in the ECU with the actual vehicle speed inputinto TERMINAL SPD of the engine control module from the combination meter, and controls the throttle body assembly tomaintain the set speed.When the actual speed is lower than the set speed, the ECU causes the current to the throttle control motor to flow fromTERMINAL M+ of the engine control module to TERMINAL 2 of the throttle body assembly to TERMINAL 1 to TERMINALM– of the engine control module. As a result, the motor in the throttle control motor is rotated to open the throttle valve toincrease the vehicle speed. When the actual driving speed is higher than the set speed, the current to the throttle bodyassembly flows from TERMINAL M– of the ECU to TERMINAL 1 of the throttle control motor to TERMINAL 2 to TERMINALM+ of the engine control module.This causes the motor in the throttle body assembly to rotate to close the throttle valve to decrease the vehicle speed.
3. Coast ControlDuring cruise control driving, while the –SET SW is on, the throttle control motor is rotated to close the throttle valve anddecrease the driving speed. The vehicle speed when the –SET SW is turned off is memorized, and the vehicle continues atthe new set speed.
4. Accel ControlDuring cruise control driving, while the +RES SW is turned on, the throttle control motor is rotated to open the throttle valveand increase the driving speed.The vehicle speed when the +RES SW is turned off is memorized and the vehicle continues at the new set speed.
5. Resume ControlIf the vehicle speed is approximately 40 km/h (25 mph) or above after canceling the set speed with the CANCEL SW,pushing the +RES SW will cause the vehicle to resume the speed set before the cancellation.
6. Manual Cancel MechanismIf any of the following signals is input during cruise control travelling, the cruise control is cancelled.∗ Depressing the clutch pedal (Cruise control clutch SW off). ”Signal is not input to TERMINAL D of the ECU” (M/T)∗ Placing the shift lever to positions except ”D” position (Park/Neutral position SW except ”D” position) (A/T)∗ Pushing the CANCEL SW (CANCEL SW on). ”Signal input to TERMINAL CCS of the ECU”∗ Pushing the CRUISE SW off ”signal input to TERMINAL CCS of the ECU”.∗ Depressing the brake pedal (Stop light SW on)
7. Tap–Up Control FunctionWhen the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can beincreased 1.6 km/h (1 mph) each time by operating the +RES SW quickly within 0.6 seconds.
8. Tap–Down Control FunctionWhen the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can belowered 1.6 km/h (1 mph) each time by operating the –SET SW quickly within 0.6 seconds.
9. Auto Cancel FunctionA) If any of the following operating conditions occurs during cruise control operation, the set speed is erased and the cruisecontrol is released, (CRUISE SW turns off).When this occurs, the ignition SW must be turned off once before the CRUISE SW will turn on.∗ When abnormality is found in the stop light SW input circuit.∗ When abnormality is found in the cancel circuit.B) If any of the following operating conditions occurs during cruise control operation, the set speed is erased and the cruisecontrol is released. (CRUISE SW turn off).When this occurs, the cancel state is cleared as the CRUISE SW will turn on again.∗ When abnormality is found in electronic throttle parts.∗ Open circuit in the stop light SW.∗ Momentary interruption of vehicle speed signal.∗ Short circuit in the stop light SW.

SRS
NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructionsand the procedure, and precautions in the Repair Manual applicable for the model year.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of informationwhen troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
Work must be started more than 90 seconds after the ignition SW is turned to the ”LOCK” position and thenegative (–) 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 fromdisconnecting the negative (–) terminal cable of the battery, the SRS may deploy.)
When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will becleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, powertelescopic 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 these memory contents. So when the work is finished, it will benecessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoiderasing the memory in each system, never use a back–up power supply from outside the vehicle.
Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.
Do not expose the following parts directly to hot air or flame;
Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;
Never use SRS parts from another vehicle. When replacing parts, replace with new parts.
For the purpose of reuse, never disassemble and repair the following parts.
If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,replace with new one.
Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.
Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.
After work on the SRS is completed, check the SRS warning light.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the RepairManual.

∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the frontairbag sensor and deceleration sensor.– Driver Airbag– Front Passenger Airbag– Seat Belt Pretensioner
∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the sideairbag sensors.– Side Airbags– Curtain Shield Airbags
∗ The dual–stage SRS airbag system has been used for the driver and front passenger airbags. This system controls theoptimal airbag inflation by judging the extent of impact, seat position (driver seat) and whether or not the seat belt isfastened(driver seat) and infomation from the Front Passenger Occupant Classification System.
∗ The front passenger occupant classification system judges whether the front passenger seat is occupied by an adult orchild (with child seat) or is unoccupied, according to the load applied to the front passenger seat and whether the seat beltis buckled. Based on the results, it restricts the deployment of the front passenger airbag, front passenger side airbag, andfront passenger seat belt pretensioner. In addition, the system informs the driver of the result of the judgment through theuse of the AIRBAG ON/OFF indicator lights.
∗ The airbag sensor assembly transmits a signal to the engine control module in order to stop the fuel pump.∗ The Airbag sensor assembly transmits a signal to the main body ECU in order to release the door lock.

1. Manual Up–and–Down FunctionDuring IG ON, one step operation upward (Pull) or downward (Push) of the door switch makes the door glass move upwardor downward. Manual operation of the power window master switch for each window can control operation of each windowremotely from the driver’s seat. The door glass stops at the position when the switch is released.
2. One–Touch Auto Down FunctionDuring IG ON, two step operation downward (Push) of the master switch of the driver’s door glass makes the driver’s doorglass move automatically downward to the full–open position. The auto operation to either direction can be suspended byone step operation to the opposite side from the operating direction.
3. Power Window Jam Protection FunctionIf a foreign object gets jammed in the window during the manual operation, the door glass automatically goes down by about50mm (or for about one second). If the door glass opening is less than 200mm after the move, the glass goes down to reachabout 200mm of the opening (or for about 5 seconds).
4. Window LockAll the power window operations except driver’s side are disabled when the window lock switch of the power window masterswitch is pressed on.
5. Fail Mode LED BlinkingSelf–diagnosis switches it to the fail mode and the indicator light (LED) in the switch knob blinks to inform the user under thefollowing conditions.∗ When abnormality is found in the hall IC that detects the position, speed and direction of the door glass.∗ When there is larger difference than the predetermined one between the position information that the hall IC detects and
the position information that the power window switch memorizes.
