How to service the Light Control Module on Mercury Grand Marquis?

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.
