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
.
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
