PINPOINT TEST K: THE DOORS DO NOT LOCK/UNLOCK USING THE REMOTE TRANSMITTER


Test K1:






Test K2-K5:






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 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.

Possible Causes
- remote transmitter battery
- remote transmitter programming
- DDM
