Principles of Operation (How Does it Work?)

CAUTION: Do not use a key, pencil or any other hard object to press the keyless entry keypad buttons. These objects may damage the keyless entry keypad buttons.

NOTE:
^ The keyless entry transmitter will not operate with the transmission in REVERSE or DRIVE.
^ The security mode operation will not function if the transmission is in gear.
^ Upon installation of a new Driver Door Module (DDM), the module must be reconfigured. Refer to Module Communications Network (Information Bus).

The DDM receives inputs from the Digital Transmission Range (TR) sensor, ignition switch, brake switch, door lock control switches, Lighting Control Module (LCM), keyless entry keypad and remote transmitter. The DDM outputs consists of keyless entry keypad illumination, door lock actuators, luggage compartment lid release solenoid, and LCM.

For DDM removal and installation information, refer to Multifunction Electronic Control Module (General Module).
