Principles Of Operation

Power Locks

The power lock/unlock feature requests all of the vehicle doors to lock or unlock upon a request from the door lock control switch, the keyless entry keypad, or the Remote Keyless Entry (RKE) transmitter. Power locking and unlocking functions independently of the key position, the vehicle speed or the transmission position. The Driver Door Module (DDM) activates internal relays to supply the correct power and grounds for the door lock actuators.

Opening the Luggage Compartment Lid with the Luggage Compartment Lid Release Switch

Without Police Package

The luggage compartment lid can be released with the RKE transmitter, the keyless entry keypad, the luggage compartment lid release switch (with the key in the ON position) or the luggage compartment lid lock cylinder.

With Police Package

The luggage compartment lid can only be released with the luggage compartment lid release switches or the luggage compartment lid lock cylinder. The RKE luggage compartment lid release function is disabled on Police package vehicles.

Remote Keyless Entry (RKE)

The DDM interprets radio frequency signals from the RKE transmitters. The DDM requests the illuminated entry feature to turn the interior lamps on when an unlock command is received.

The RKE transmitter supplies a signal to the Tire Pressure Monitoring System (TPMS) /RKE antenna when any button is pressed. The TPMS /RKE antenna is hardwired to the DDM and sends the RKE signal to the DDM. The DDM interprets the RKE signal then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors or release the luggage compartment lid. The RKE transmitter can also be used to activate the panic alarm.

Keyless Entry Keypad

The keyless entry keypad is hardwired to the DDM. The DDM interprets the inputs from the keyless entry keypad and then controls the associated operation. The keyless entry keypad is illuminated for 5 seconds when any button is pressed. The DDM requests the illuminated entry feature to turn the interior lamps on when a valid entry code is received. If a lock all doors code is entered, the illuminated entry feature turns off.

NOTE: The keyless entry keypad does not lock the doors if the driver door is ajar.

The keyless entry keypad supplies a signal to the DDM when the buttons are pressed. The DDM then supplies voltage to the appropriate door lock actuator(s) to lock or unlock the doors or release the luggage compartment lid.
