Operation CHARM: Car repair manuals for everyone.

General Information

The keyless entry system allows the driver to do the following functions from outside the vehicle by using a hand held radio transmitter:
^ Unlock the door locks. The courtesy lights activate automatically when using this function.
^ Lock the door locks.
^ Release the rear compartment lid.
^ Activate the remote alarm.

The transmitter operates in the UHF band. The transmitter sends digitally code signals to the Remote Control Door Lock Receiver (RCDLR) when pressing any of the transmitter buttons.

The RCDLR detects and decodes transmitter signals. For locking, unlocking, rear compartment lid releasing and remote alarm commands, the RCDLR sends command messages to the Body Control Module (BCM) in order to operate the door locks actuators, the courtesy lights, the rear compartment lid release actuator and the remote alarm.

Door lock, lighting and rear compartment lid release systems may also be operated in the usual manner. For example, the door locks respond to the door lock switches.

The keyless entry system may be programmed with up to 4 keyless entry transmitters.
