Component Tests and General Diagnostics

1. INSPECT POWER WINDOW MASTER SWITCH CONTINUITY







Driver's switch:







Passenger's switch: Window unlock







Passenger's switch: Window lock

If continuity is not as specified, replace the switch.

2. INSPECT ONE-TOUCH POWER WINDOW SYSTEM CURRENT OF CIRCUIT (Using an ammeter)




a. Disconnect the connector from the master switch.
b. Connect the positive (+) lead from the ammeter to terminal 3 on the wire harness side connector and the negative (-) lead to negative (-) terminal of the battery.
c. Connect the positive (+) lead from the battery to terminal 4 on the wire harness side connector.
d. As the window goes down, check that the current flow is approximately 7 A.




e. Check that the current increases up to approximately 14.5 A or more when the window stops going down.

HINT: The circuit breaker opens some 4 - 40 seconds after the window stops going down, so that check must be done before the circuit brake operates.

If the operation is not as specified, replace the switch.

3. INSPECT ONE-TOUCH POWER WINDOW SYSTEM/CURRENT OF CIRCUIT (Using an ammeter with a current-measuring probe)




a. Remove the master switch with connector connected.
b. Attach a current-measuring probe to terminal 9 of the wire harness.
c. Turn the ignition switch ON and set power window switch in the down position.
d. As the window goes down, check that the current flow is approximately 7 A.




e. Check that the current increases up to approximately 14.5 A or more when the window stops going down.

HINT: The circuit breaker opens some 4 - 40 seconds after the window stops going down, so that check must be done before the circuit breaker operates.

If operation is not as specified, replace the master switch.







4. INSPECT PASSENGER'S DOOR POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.







5. INSPECT POWER MAIN RELAY CONTINUITY
If continuity is not as specified, replace the switch.




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




7. Passenger's 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 counter clockwise.
b. Revers the polarity, check that the motor turns clockwise.
If operation is not as specified, replace the motor.

8. Driver's Door:
INSPECT POWER WINDOW MOTOR CIRCUIT BREAKER OPERATION




a. Disconnect the connector from the master switch.
b. Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 4 on the wire harness side connector and raise the window to fully closed position.




c. Continue to apply voltage, check that a circuit breaker operation noise is heard within approximately 4 to 40 seconds.
d. Reverse the polarity, check that the window begins to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.

9. Passenger's Door:
INSPECT POWER WINDOW MOTOR CIRCUIT BREAKER OPERATION




a. Disconnect the connector from the power window switch.
b. Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 1 on the wire harness side connector, and raise the window to fully closed position.




c. Continue to apply voltage, check that circuit breaker operation noise is heard within approximately 4 to 40 seconds.
d. Revers the polarity, check that the window begins to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.







10. 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.
