Component Tests

INSPECTION

1. INSPECT POWER WINDOW MASTER SWITCH CONTINUITY







a. Inspect the front driver's switch.
Window unlock:
If continuity is not as specified, replace the master switch.







b. Inspect the front passenger's switch.
Window unlock:
If continuity is not as specified, replace the master switch.







c. Inspect the rear left switch.
Window unlock:
If continuity is not as specified, replace the master switch.







d. Inspect the rear right switch.
Window unlock:
If continuity is not as specified, replace the master switch.




2. INSPECT POWER WINDOW MASTER SWITCH ILLUMINATION
a. Set the window lock switch to the unlock position.
b. Connect the positive (+) lead from the battery to terminal 12 and the negative (-) lead to terminal 7, and check that all the illuminations light up.




c. Set the window lock switch to the lock position, check that all the passenger's power window switch illuminations go out.
If operation is not as specified, replace the master switch.







3. INSPECT POWER WINDOW MASTER SWITCH CIRCUIT
Disconnect the connector from the master switch and inspect the connector on the wire harness side.
If the circuit is not as specified, inspect the circuits connected to other parts.







4. Passenger's side:
INSPECT POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







5. INSPECT POWER WINDOW SWITCH CIRCUIT
Disconnect the connector from the switch and inspect the connector on the wire harness side.
If the circuit is not as specified, inspect the circuits connected to other parts.







6. Rear door side:
INSPECT POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







7. INSPECT POWER MAIN RELAY CONTINUITY
If continuity is not as specified, replace the relay.

8. INSPECT POWER MAIN RELAY CIRCUIT







9. INSPECT POWER WINDOW ECU (MOTOR) CIRCUIT
Disconnect the connector from the ECU and inspect the connector on the wire harness side.

HINT: The power window ECU does not operate even if battery voltage is applied to the connector of the driver's door power window ECU directly.

Do not apply the battery voltage directly because this will cause the controller broken.
Each regulator does not have stop function. Operate manually and never operate to the highest position.
If the circuit is as specified, replace the ECU.
If the circuit is not as specified, inspect the circuits connected to other parts.




10. Rear left side door:
INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the motor turns counterclockwise.
b. Reverse the polarity, check that the motor turns clockwise.
If operation is not as specified, replace the motor.




11. Rear right side door:
INSPECT POWER WINDOW MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the motor turns counterclockwise.
b. Reverse the polarity, check that the motor turns clockwise.
If operation is not as specified, replace the motor.




12. Key-off power window signal:
INSPECT INTEGRATION RELAY OPERATION

HINT: When the relay circuit is as specified, inspect the key-off power window signal.

a. Connect the positive (+) lead from the voltmeter to terminal A3 and the negative (-) lead to body ground.
b. Close the door with ignition switch turned to LOCK or ACC, and check that the meter needle indicates battery positive voltage.
c. Open the door and check that the meter needle indicates 0 V.




d. Turn the ignition switch ON and check that the meter needle indicates battery positive voltage again.
If operation is not as specified, replace the relay.

13. INSPECT INTEGRATION RELAY CIRCUIT
Inspect the switch adjustment procedures.
1. Connect the power window master switch to the wire harness and turn the ignition switch ON.
2. Fully open the door glass manually.
3. Using a round bar that is 2 sq.mm, press the reset switch.

CAUTION: When using an iron wire, take care not to use a wire with a sharp edge.

4. With the reset switch pressed, fully open the door glass with the master switch.

CAUTION:
- Operate manually.
- While opening the door glass, if any vibration is felt on the pressed reset switch, pressing force is weak, so repeat step (2).

5. Remove the bar and fully open the door glass.
6. Check that the door glass can be opened and closed fully by AUTO operation.
7. Checklist for power window malfunction.
