CONSULT-III ACTIVE TEST

1. Select "DAYTIME RUNNING LIGHT" of BCM (HEAD LAMP) active test item.
2. With operating the test item, check the daytime light operation.

On : Daytime running light ON 

Off : Daytime running light OFF 

OK or NG 

OK: GO TO 2.

NG: GO TO  4.

CONSULT-III DATA MONITOR

1. Select "ENGINE RUN" of BCM (HEAD LAMP) data monitor item.
2. With operating the engine running or stop, check the monitor status.

Engine running : ENGINE RUN ON 

Engine stop : ENGINE RUN OFF 

3. Select "PKB SW" of BCM (HEAD LAMP) data monitor item.
4. With operating the parking brake, check the monitor status.

Parking brake ON : PKB SW ON 

Parking brake OFF : PKB SW OFF 

OK or NG 

OK: GO TO  3.

NG: Check BCM CAN communication system. Refer to "CAN COMMUNICATION UNIT ".

1. Start engine and release parking brake. Headlamp switch OFF.
2. Select "DTRL REQ" of IPDM E/R data monitor item.
3. With operating the parking brake, check the monitor status.

   Parking brake ON : DTRL REQ ON 

   Parking brake OFF : DTRL REQ OFF 

OK or NG 

OK: Replace IPDM E/R. Refer to "REMOVAL AND INSTALLATION OF IPDM E/R ".

NG: Replace BCM. Refer to "REMOVAL AND INSTALLATION OF BCM ".

1. Turn ignition switch OFF.
2. Remove daytime light relay.
3. Check voltage between daytime light relay harness connector and ground.
