                                               HOW TO USE THIS MANUAL B

This manual provides information on the electrical circuits installed on vehicles by
dividing them into a circuit for each system.

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 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__). When overall connections are required, see the Overall Electrical
Wiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL
    [O]        System Outline
          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 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 lamp 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

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points ( A1 , A2 and D4 shown below) can also be
checked this way.

The ”Current Flow Chart” section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.

                   The chart below shows the route by which current flows from the battery to each electrical source

       System Outline
1. Electronic Fuel Injection
 It controls to have appropriate fuel injection according to the basic injection time. The basic injection time is calculated to fit
 the engine condition and is corrected with signals from various sensors.
2. Electronic Spark Advance
 Appropriate ignition is conducted according to the basic ignition timing which is calculated to fit the engine condition after
 correcting it with signals from various sensors.
3. Electronic Throttle Control System–intelligent
 It controls to have appropriate throttle opening according to the throttle opening calculated to fit the engine condition after
 correcting it with signals from various sensors.
4. Variable Valve Timing–intelligent
 It improves engine output, reduces exhaust gas and improves fuel consumption by varying the phase of the intake camshaft
 in accordance with the engine condition.
5. Electric Fan Control
 It controls the switching ON/OFF and fan speed of the cooling fan according to the coolant temperature and air conditioner’s
 condition.
6. Fuel Pump Control
 It turns ON/OFF the fuel pump according to the starter signal and engine speed signal. It stops the fuel pump operation
 according to signals from the airbag sensor assembly center.
7. Air Conditioning Cut–Off Control
 It reduces load of the air conditioner’s compressor in acceleration in order to secure the drivability.
8. Canister Purge Control
 It controls the purge flow volume of the canister according to the coolant temperature and driving condition.
9. Cranking Hold Control
 It continues to supply electricity to the starter between the start of cranking and the engine start in order to prevent the
 engine start failure by the key’s switching off just before the engine’s complete explosion.
10. Oxygen Sensor Control
 It switches ON/OFF the oxygen sensor according to the coolant temperature and driving condition.
11. Diagnosis
 It realizes accurate and detailed diagnosis of a failure such as calling the SAE specified diagnosis code data and active test
 by using the diagnosis tool.
12. Fail–Safe
 When the engine control module detects abnormality in signals of the sensors, it stops or continues to control the engine by
 using the standard values in the engine control module.

      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 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 at
 the time the SET SW is released is memorized in the ECU as the set speed.
2. Set Speed Control
 During cruise control driving, the ECU compares the set speed memorized in the ECU with the actual vehicle speed input
 into TERMINAL SPD of the engine control module from the combination meter, and controls the throttle body assembly to
 maintain 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 from
 TERMINAL M+ of the engine control module to TERMINAL 2 of the throttle body assembly to TERMINAL 1 to TERMINAL
 M– of the engine control module. As a result, the motor in the throttle control motor is rotated to open the throttle valve to
 increase the vehicle speed. When the actual driving speed is higher than the set speed, the current to the throttle body
 assembly flows from TERMINAL M– of the ECU to TERMINAL 1 of the throttle control motor to TERMINAL 2 to TERMINAL
 M+ 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 Control
 During cruise control driving, while the –SET SW is on, the throttle control motor is rotated to close the throttle valve and
 decrease the driving speed. The vehicle speed when the –SET SW is turned off is memorized, and the vehicle continues at
 the new set speed.
4. Accel Control
 During cruise control driving, while the +RES SW is turned on, the throttle control motor is rotated to open the throttle valve
 and 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 Control
 If 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 Mechanism
 If 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 Function
 When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can be
 increased 1.6 km/h (1 mph) each time by operating the +RES SW quickly within 0.6 seconds.
8. Tap–Down Control Function
 When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can be
 lowered 1.6 km/h (1 mph) each time by operating the –SET SW quickly within 0.6 seconds.
9. Auto Cancel Function
 A) If any of the following operating conditions occurs during cruise control operation, the set speed is erased and the cruise
 control 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 cruise
 control is released. (CRUISE SW turn off).
 When this occurs, the cancel state is cleared as the CRUISE SW will turn on again.

ABS
      System Outline
 1. Speed Sensor
  Detects the wheel speed of each of four wheels.
 2. Skid Control ECU
  Based on signals from the sensors, it judges the vehicle driving condition and sends the brake control signal to the brake
  actuator.
 3. ABS Warning Light
  Lights up to alert the driver when the ECU detects a malfunction in the ABS system and stopps the system.
 4. Brake Warning Light
  Lights up simultaneously with the ABS warning light to alert the driver when the ECU detects a malfunction not only in the
  ABS but also in the EBD. Single light–up of the brake warning light alerts the driver when the ECU detects a malfunction in
  the brake system.
 5. Engine Control Computer
  Sends signals such as park/neutral position SW, TC switch, etc., to the skid control ECU with actuator.

NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions
and the procedure, and precautions in the Repair Manual applicable for the model year.

 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 more than 90 seconds after the ignition SW 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 deploy.)

 D When the negative (–) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
   cleared. 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, 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 these memory contents. So when the work is finished, it will be
   necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid
   erasing the memory in each system, never use a back–up power supply from outside the vehicle.

 D Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.

 D Do not expose the following parts directly to hot air or flame;

 D Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;

 D Never use SRS parts from another vehicle. When replacing parts, replace with new parts.

 D For the purpose of reuse, never disassemble and repair the following parts.

 D If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,
   replace with new one.

 D Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting electrical circuits of the system.

 D Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.

 D After work on the SRS is completed, check the SRS warning light.

 D If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
   Manual.

SRS
        System Outline
  ∗ The system reaches an ignition judgment to deploy the following device based on the signals received from the front
    airbag 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 side
    airbag 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 the
    optimal airbag inflation by judging the extent of impact, seat position (driver seat) and whether or not the seat belt is
    fastened(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 or
    child (with child seat) or is unoccupied, according to the load applied to the front passenger seat and whether the seat belt
    is buckled. Based on the results, it restricts the deployment of the front passenger airbag, front passenger side airbag, and
    front passenger seat belt pretensioner. In addition, the system informs the driver of the result of the judgment through the
    use 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.

       System Outline
  ∗ In order to reduce driver’s steering force, the assist current is calculated from the torque sensor signal and vehicle speed
    signal of the meter or CAN communication to output to the motor.
  ∗ When abnormality occurs in the system, the assist is prohibited by shutting off the power source relay and motor relay in
    ECU, and the warning light (P/S) in the meter is lit up.

      System Outline
1. Manual Up–and–Down Function
 During IG ON, one step operation upward (Pull) or downward (Push) of the door switch makes the door glass move upward
 or downward. Manual operation of the power window master switch for each window can control operation of each window
 remotely from the driver’s seat. The door glass stops at the position when the switch is released.
2. One–Touch Auto Down Function
 During IG ON, two step operation downward (Push) of the master switch of the driver’s door glass makes the driver’s door
 glass move automatically downward to the full–open position. The auto operation to either direction can be suspended by
 one step operation to the opposite side from the operating direction.
3. Power Window Jam Protection Function
 If a foreign object gets jammed in the window during the manual operation, the door glass automatically goes down by about
 50mm (or for about one second). If the door glass opening is less than 200mm after the move, the glass goes down to reach
 about 200mm of the opening (or for about 5 seconds).
4. Window Lock
 All the power window operations except driver’s side are disabled when the window lock switch of the power window master
 switch is pressed on.
5. Fail Mode LED Blinking
 Self–diagnosis switches it to the fail mode and the indicator light (LED) in the switch knob blinks to inform the user under the
 following 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.

Front Wiper and Washer
       System Outline
 1. Intermittent Function
  When the wiper control switch is turned to INT position, the wiper makes intermittent operation with an interval time of
  approximately 3.3 seconds.
 2. Washer–Linked Function
  When the washer switch is turned ON for approximately 0.3 seconds or more, the wiper starts a LO operation at the same
  time as the washer fluid is ejected. When the switch is turned ON for approximately 1.5 seconds or more, the wiper keeps a
  LO operation for approximately 2.2 seconds after the washer switch is turned OFF, and then stops its operation.
