If continuity and voltage are not as specified, replace the master switch.




INSPECT POWER WINDOW MASTER SWITCH ILLUMINATION
Connect the positive (+) lead from the battery to terminal 3 and 10, and the negative (-) lead to terminal 4, and check that all the illuminations light up.
If operation is not as specified, replace the master switch.

Using an ammeter:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/CURRENT OF CIRCUIT




a. Disconnect the connector from the master switch.
b. Connect the positive (+) lead from the ammeter to terminal 1 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 2 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 made before the circuit breaker operates.
If the operation is not as specified, replace the master switch.

Using an ammeter with a current-measuring probe:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/CURRENT OF CIRCUIT




a. Remove the master switch with connector connected.
b. Attach a current-measuring probe to terminal 1 of the wire harness.
c. Turn the ignition switch ON and set the 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 made before the circuit breaker operates.

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




INSPECT POWER WINDOW SWITCH CONTINUITY




If continuity is not as specified, replace the switch.





1. INSPECT POWER QUARTER WINDOW SWITCH CONTINUITY




If continuity is not as specified, replace the switch.

2. Left side:
INSPECT POWER VENT WINDOW MOTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the window link moves to OPEN position.




b. Remove the polarity and check that the window link moves to CLOSE position.
If operation is not as specified, replace the window motor.

3. Right side:
INSPECT POWER VENT 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 window link moves to OPEN position.




b. Remove the polarity and check that the window link moves to CLOSE position.
