COMBINATION SWITCH INPUT CIRCUIT

Diagnosis Procedure

INFOID:0000000009693655

Regarding Wiring Diagram information, refer to 

BCS-111, "Wiring Diagram"

.

1.

CHECK INPUT 1 - 5 CIRCUIT FOR OPEN

1. Turn ignition switch OFF.

2. Disconnect BCM and combination switch connectors.

3. Check continuity between BCM connector and combination switch connector.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair harness or connectors.

2.

CHECK INPUT 1 - 5 CIRCUIT FOR SHORT

Check for continuity between BCM connector and ground.

Is the inspection result normal?

YES

>> Repair harness or connectors.

NO

>> GO TO 3.

3.

CHECK BCM OUTPUT VOLTAGE

1. Connect BCM connector.

2. Check voltage between BCM connector and ground.
