Trailer Lighting Control Module Configuration/Reconfiguration and Setup

If the trailer lighting control module is replaced or installed as an after sales accessory, both the configuration/reconfiguration and setup procedures must be performed.

1. Access the Service Programming System (SPS) and follow the on-screen instructions. Refer to Service Programming System (SPS) .
2. On the SPS Supported Controllers screen, select Trailer Interface (Control) Module - Configuration and Setup.
3. On the Control Module - Configuration and Setup Function(s) screen, select both ECU Configuration/Reconfiguration and ECU Setup menu options and follow the on-screen instructions.
4. Clear DTCs after completing the configuration/reconfiguration and setup procedures.

If the trailer lighting control module fails to accept the configuration/reconfiguration and setup procedures, verify all scan tool and trailer lighting control module connections are secure.
