Description

Sends AUTO signal to driver side or passenger side power window motor.

Component Function Check

1.CHECK FUNCTION

Check that corresponding power window operates when driver side or passenger side switch of power window main switch (power window lock is UNLOCK) is operated to the AUTO position.

Is the inspection result normal?

YES>>Power window main switch AUTO function is OK.

NO>>Refer to Diagnosis Procedure.

Diagnosis Procedure

1.CHECK POWER WINDOW AUTO FUNCTION

Turn ignition switch ON.
Power window lock switch UNLOCK.
Operate driver side and passenger side switch of power window main switch to the AUTO position.

Which side of power window AUTO operation does not operate?

Driver side>>GO TO 2.

Passenger side>>GO TO 5.

2.CHECK DRIVER SIDE POWER WINDOW MOTOR INPUT SIGNAL
