Lamp Control Module: Description and Operation

The lamp control module is installed in the electrical carrier in the trunk. The module monitors the supplies to the tail lamps, stop lamps (not High Mounted Stop Lamp (HMSL)), license plate lamps and rear side marker lamps. If it detects a bulb failure, the lamp control module outputs a signal to the SLM. On receipt of the bulb failure signal, the SLM outputs a SCP - REAR BULB FAIL message to the major instrument cluster. The major instrument cluster then switches on the amber general warning lamp and shows the BULB FAIL REAR message on the driver information display.
