PRINCIPLES OF OPERATION
CAUTION: Do not use a key, pencil or any other hard object to press the keyless entry keypad buttons. These objects may damage the buttons.
NOTE: The remote transmitter will not operate with the transmission in REVERSE or DRIVE.
The driver door module (DDM) receives inputs from the digital transmission range (TR) sensor, ignition switch, seat switch, window/door lock control switches, lighting control module (LCM), keyless entry keypad and remote transmitter. The DDM outputs consist of keyless entry keypad illumination, door lock actuators, luggage compartment release solenoid, power luggage compartment lid module (if equipped), horn relay and LCM.
The keyless entry keypad can be programmed with an alternate code. The alternate code can be entered by entering the 5-digit permanent entry code into the keyless entry keypad. Within 5 seconds of pressing the last button of the permanent code, press the 1/2 button and enter any alternate 5-digit code. After programming, the doors will signal by locking and then unlocking. Both the autolock and locking confirmation horn chirp can be enabled and disabled by the customer.
Programming the remote transmitter is accomplished by using the diagnostic tool or the Remote Transmitter Programming.
