BCM (BODY CONTROL MODULE) : Diagnosis Procedure

INFOID:0000000005516011

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.

FRONT WIPER MOTOR LO CIRCUIT

Component Function Check

INFOID:0000000005516013

1.

CHECK FRONT WIPER LO OPERATION

IPDM E/R AUTO ACTIVE TEST

1.

Start IPDM E/R auto active test. Refer to 

PCS-10, "Diagnosis Description"

.

2.

Check that the front wiper operates at the LO operation.

CONSULT-III ACTIVE TEST

1.

Select “FRONT WIPER” of IPDM E/R active test item.

2.

With operating the test item, check front wiper operation.

Is front wiper (LO) operation normally?

YES

>> Front wiper motor LO circuit is normal.

NO

>> Refer to 

WW-28, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000005516014

1.

CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE

CONSULT-III ACTIVE TEST

1.

Turn the ignition switch OFF.

2.
