Daytime Running Lamp: Testing and Inspection

INSPECTION AND VERIFICATION

NOTE: When installing a new smart junction box (SJB), it must be reconfigured for this feature if originally equipped. Refer to Information Bus (Module Communications Network).

1. Verify the customer concern by operating the DRL following these steps:
- Place the ignition switch in the RUN position.
- Place the headlamp switch in the OFF position.
- Fully apply the brake.
- Release the parking brake.
- If the DRL does not operate, make sure the SJB is configured for DRL before proceeding to the next step.

2. Verify the parking lamp operation.
- Place the headlamp switch in the parking lamps ON position.
- If the parking lamps do not operate correctly, refer to Parking Lamp.
- If the parking lamps operate correctly, go to the next step.

3. Verify the high beam operation.
- Place the headlamp switch in the headlamps ON position.
- Place the multifunction switch in the high beam position.
- If the high beams operate correctly and the DRL operation is incorrect, install a new SJB. Test the system for normal operation.
- If the high beams do not operate correctly, refer to Headlamp for correct diagnosis.
