OK or NG
- OK: GO TO 4.
- NG: Repair harness or connector.
- CHECK GROUND
- Check continuity between clearance lamp RH harness connector E23 terminal 3 (B) and ground.
- 3 (B) - Ground: Continuity should exist.
- Check continuity between clearance lamp LH harness connector E43 terminal 3 (B) and ground.
- 3 (B) - Ground: Continuity should exist.
OK or NG
- OK: GO TO 5.
- NG: Repair harness or connector.
- Check continuity between clearance lamp RH harness connector E23 terminal 3 (B) and ground.
- CHECK BULB
Inspect bulbs of lamp which do not illuminate.
OK or NG
- OK: GO TO 6.
- NG: Replace bulb.
- CHECK DAYTIME RELAY CIRCUIT
- Disconnect combination meter connector.
- Check continuity between daytime lamp relay harness connector E15 terminal 1 (L) and combination meter harness connector M20 terminal 10 (L/W).
- 1 (L)-10(L/W): Continuity should exist.
OK or NG
- OK: GO TO 7.
- NG: Repair harness or connector.
- CHECK INPUT SIGNAL
- Connect combination meter connector.
- Start engine running.
- Select "BCM" on CONSULT-II. With "HEAD LAMP" data monitor, make sure "ENGINE RUN" turns ON-OFF linked with operation of engine running or stop.
- Engine running: ENGINE RUN ON
- Engine stop: ENGINE RUN OFF
- Select "BCM" on CONSULT-II. With "HEAD LAMP" data monitor, make sure "PKB SW" turns ON-OFF linked with operation of parking brake switch.
- Parking brake ON: PKR SW ON
- Parking brake OFF: PKR SW OFF
OK or NG
- OK: Replace BCM. Refer to "REMOVAL AND INSTALLATION OF BCM ".
- NG: GO TO 8.
- CHECKING CAN COMMUNICATIONS
Select "BCM" by CONSULT-II, and perform self-diagnosis for "BCM".
Displayed self-diagnosis results
- NO DTC: Replace BCM. Refer to "REMOVAL AND INSTALLATION OF BCM ".
- CAN COMM CIRCUIT: Check BCM CAN communication system.
Refer to "CAN COMMUNICATION INSPECTION USING CONSULT-II (SELF-DIAGNOSIS) ".
