Lamp Control Module: Service and Repair

Lighting Control Module (LCM)









Removal and Installation

NOTE: Prior to removal of the module, it is necessary to upload module configuration information to a scan tool. This information needs to be downloaded into the new module once installed.

1. NOTE: This step is necessary only if the Lighting Control Module (LCM) is being replaced.

NOTE: A new LCM is delivered in a manufacturing mode with a pre-set DTC of B2477. This DTC will clear when the module has been successfully configured (or Programmable Module Installation (PMI)). DTC B2477 may need to be cleared after a successful configuration (or PMI).
Upload the module configuration information from the LCM into the scan tool. For additional information, refer to Information Bus.

4. Remove the accelerator pedal.

5. Remove the 2 screws and position the LCM aside.

6. Release the locking tabs, disconnect the electrical connectors and remove the LCM.

7. NOTE: If a new module is installed, it is necessary to download the module configuration information from the scan tool into the new module.
To install, reverse the removal procedure.
