Lighting Control Module

Service operations on the Lighting Control Module (LCM) demand personnel to transfer its configuration data to a diagnostic tool before module removal because this data needs to be downloaded to the new module post-installation. Begin by disconnecting the battery. Begin by removing the pin-type retainers on the LH instrument panel before placing the LH instrument panel lower insulator to the side. You must first disconnect the courtesy lamp and then take out the LH instrument panel lower insulator. Uninstall the parts consisting of the accelerator pedal and shaft. Two screws should be removed and LCM placed aside. The technician should unlock the locking tabs, detach electrical connectors and then remove the LCM. You should download the module configuration information from the diagnostic tool into the new module after its installation. Such installation requires following the reverse order of removal procedures.

Service of the Lighting Control Module (LCM) starts with uploading module configuration information to a scan tool because this data needs downloading into the new module following installation. The new LCM enters manufacturing mode through arrival with a default DTC B2477 that clears upon establishing necessary programming. If necessary, clear DTC B2477 after configuration. Start the process by removing the pin-type retainers before placing the LH instrument panel lower insulator aside. Starting with the courtesy lamp disconnected one should pull out the LH instrument panel lower insulator. Follow step one by taking away the accelerator pedal and use a screwdriver to remove the two attachment screws from the LCM before placing it aside. Detach the locking tabs before disconnecting electrical plugs to separate the LCM. Install the new module before retrieving configuration data from the scan tool to transfer into the module. The installation process should finish by following all steps in reverse order.
