Normal Operation

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.

Remote locking and unlocking of the doors is accomplished by the driver door module (DDM) receiving a command message from the remote keyless entry (RKE) transmitter. The DDM processes the command and sends a signal directly to the driver door latch. The DDM sends a message through the standard corporate protocol (SCP) network to the rear electronic module (REM), which activates the passenger door latches. Fault management disables the remote locking and unlocking feature in the event of an invalid or missing ignition switch or PRNDL message to the DDM.

All RKE transmitters must be present to begin diagnosis of the RKE system.

Aftermarket or dealer-installed systems may adversely affect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.
