Driver Door Module (DDM), Passenger Door Module (PDM)

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

The DDM/PDM may sometimes be called the driver door switch/passenger door switch. When equipped, the DDM and PDM receive discrete inputs from the front door ajar switches. The DDM and PDM send a serial data message to the BCM indicating the status of the front door ajar switches. The DDM also monitors the door cylinder switch with a discrete input. When the door key is used the DDM sends a serial data message to the BCM indicating that a key has been used to unlock the driver door cylinder and the BCM will disarm CTD system.
