BCM (BODY CONTROL MODULE) : Diagnosis Procedure

INFOID:0000000009719728

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

FRONT WIPER MOTOR LO CIRCUIT

Component Function Check

INFOID:0000000009719730

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 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-30, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009719731

1.

CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE

1.

Turn the ignition switch OFF, and wait for 20 seconds or more.

2.

Disconnect front wiper motor connector.

3.

Turn the ignition switch ON, and wait for 10 seconds.

4.

Check voltage between IPDM E/R harness connector and ground.

*: According to front wiper protection function, IPDM E/R supplies voltage for 10 seconds (battery voltage) and
then stops for 20 seconds (0 V). This operations repeats 5 times, and then IPDM E/R stops voltage supply. To
perform the check again, turn ignition switch OFF, wait for 20 seconds or more, and then perform the check.

Is the measurement value normal?

YES

>> GO TO 2.

NO

>> Replace IPDM E/R.

2.

CHECK FRONT WIPER MOTOR (LO) OPEN CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

Check continuity between IPDM E/R harness connector and front wiper motor harness connector.

Does continuity exist?

YES

>> GO TO 3.

NO

>> Repair the harness or connector.

3.

CHECK FRONT WIPER MOTOR (LO) SHORT CIRCUIT

Check continuity between IPDM E/R harness connector and ground.

Lo

: Front wiper (LO) operation

Off

: Stop the front wiper.
