Normal Operation
Remote locking and unlocking of the doors is accomplished by the driver door module (DDM) receiving a command message from the remote transmitter. The DDM processes the command and sends a signal directly to the driver door latch. The DDM sends a message through the SCP network to the rear electronic module (REM) which drives activates the passenger door latches. Fault management disables the remote locking and unlocking feature in the event of an ignition switch or PRNDL invalid or missing message to the DDM.
All remote transmitters must be present to begin diagnosis of the remote keyless entry (RKE) system.
Aftermarket or dealer-installed systems may adversely effect the RKE system operation. These systems should be disconnected before diagnosing any remote keyless entry (RKE) concerns.
