Daytime Running Lamp: Testing and Inspection
INSPECTION AND VERIFICATION
NOTE: When installing a new smart junction box (SJB), it must be configured for this feature, if originally equipped. Refer to Information Bus
(Module Communications Network).
1. Verify the customer concern by operating the daytime running lamps (DRL) following these steps:
1
Place the ignition switch in the RUN position.
2
Place the headlamp switch in the OFF position.
3
Place the transaxle in any gear except PARK.
4
If the DRL does not operate, make sure the SJB is configured for DRL before proceeding to the next step.
2. Verify the turn signal lamp operation.
-
Place the multifunction switch in the LH and RH TURN positions.
-
If the turn signal lamps do not operate correctly, refer to Turn Signals to continue diagnosis of the turn signal lamps.
-
If the turn signals operate correctly, proceed to the next step.
3. Check the transmission control module (TCM) PIDs.
-
Monitor the TCM PIDs while placing the gear selector lever through all positions.
-
If the gear selection does not match the PIDs, refer to Transmission Control Systems to continue diagnosis of the transaxle.
-
If the gear selection does match the PIDs and the DRL operation is incorrect, install a new SJB. Refer to Body Control Systems
(Multifunction Electronic Control Module). Test the system for normal operation.
