BCM : Diagnosis Procedure

INFOID:0000000010064716

Regarding Wiring Diagram information, refer to 

BCS-67, "Wiring Diagram"

.

1.

 CHECK FUSE AND FUSIBLE LINK

Check if the following BCM fuses or fusible link are blown.

Is the fuse or fusible link blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit.

NO

>> GO TO 2

2.

 CHECK POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect BCM.

3. Check voltage between BCM harness connector and ground.

Is the measurement normal?

YES

>> GO TO 3

NO

>> Repair or replace harness.

3.

 CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> Inspection End.

NO

>> Repair or replace harness.
