BCM (BODY CONTROL MODULE) : Diagnosis Procedure

INFOID:0000000010092635

1.

CHECK FUSE AND FUSIBLE LINK

Check that the following fuse and fusible link are not blown.

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.

Component Function Check

INFOID:0000000009723026

1.

CHECK HEADLAMP (HI) OPERATION

IPDM E/R AUTO ACTIVE TEST

1.

Activate IPDM E/R auto active test. Refer to 

PCS-10, "Diagnosis Description"

.

2.

Check that the headlamp switches to the high beam.

CONSULT ACTIVE TEST

1.

Select “EXTERNAL LAMPS” of IPDM E/R active test item.

2.

With operating the test items, check that the headlamp (HI) is turned ON.

NOTE:
ON/OFF is repeated 1 second each.

Is the headlamp (HI) turned ON?

YES

>> Headlamp (HI) circuit is normal.

NO

>> Refer to 

EXL-223, "Diagnosis Procedure"

.
