Reversing Lamps
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The reversing lamps are controlled by the REM and powertrain control module (PCM). The PCM sends a message through the SCP communication network to the REM indicating the transmission is in REVERSE. The REM processes this information and outputs the command to the reversing lamps which are hard-wired to the REM. Fault management of the reversing lamps will provide limited reversing lamp functionality. In the event of missing or invalid transmission data, the reversing lamps remain in the last state of operation prior to the failure for one key cycle. In the event of invalid or missing data for the ignition switch, the lamps will work in relation to PRNDL messages.
