POWER SUPPLY AND GROUND CIRCUIT
Diagnosis Procedure
INFOID:0000000006014910
1.
CHECK FUSES AND FUSIBLE LINK
Check that the following fuses and fusible link are not fusing.
Is the fuse fusing?
YES
>> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is
blown.
NO
>> GO TO 2.
2.
CHECK POWER SUPPLY CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect BCM connectors.
3.
Check voltage between BCM harness connector and ground.
Is the measurement value normal?
YES
>> GO TO 3.
NO
>> Repair harness or connector.
3.
CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
Does continuity exist?
YES
>> INSPECTION END
NO
>> Repair harness or connector.
