POWER SUPPLY AND GROUND CIRCUIT

POWER WINDOW MAIN SWITCH

POWER WINDOW MAIN SWITCH : Description

INFOID:0000000000961545

• BCM supplies power.
• It operates each power window motor via corresponding power window switch and makes window move up/

down when power window main switch is operated.

POWER WINDOW MAIN SWITCH : Component Function Check

INFOID:0000000000961546

1.

 CHECK POWER WINDOW MAIN SWITCH FUNCTION

Does power window motor operate with power window main switch operation? 

Is the inspection result normal?

YES

>> Power window main switch power supply and ground circuit are OK.

NO

>> Refer to 

PWC-15, "POWER WINDOW MAIN SWITCH : Diagnosis Procedure"

.

POWER WINDOW MAIN SWITCH : Diagnosis Procedure

INFOID:0000000000961547

1.

CHECK POWER SUPPLY CIRCUIT 

1.

Turn ignition switch ON.

2.

Check voltage between power window main switch connector and ground.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK HARNESS CONTINUITY 

1.

Turn ignition switch OFF.

2.

Disconnect BCM connector and power window main switch connector.

3.

Check continuity between BCM connector and power window main switch connector.

4.
