Operation CHARM: Car repair manuals for everyone.

General Description

The remote lock control system is used to lock and unlock the doors and release the rear compartment lid of the vehicle. A small receiver is mounted in the right body hinge pillar trim panel assembly. The transmitter is a hand-held item that is attached to a key ring. The transmitter has three buttons that control the functions of the system.

The remote door lock receiver is battery fed and is always monitoring the transmitter signal. When the correct transmitter signal is received to lock all of the doors, a transistor driver will energize the correct lock control relay coil. The receiver will also control which lock control relays will be energized to unlock the driver's door or all of the doors and the illumination of the courtesy lamps.

Sustained interior illumination includes a feature called theater dimming. With theater dimming, the lamps don't just turn off at the end of delay time. Instead, they slowly dim during the delay time until they go out. the delay time is canceled if you turn the ignition key to RUN or START, so the lamps will go out right away.

When the ignition is on, Sustained Interior illumination is inactive, which means the courtesy lamps won't come on.

The transmitter will transmit a radio signal to the receiver, which will control the three functions of the remote door lock receiver. The range is approximately 10 meters (33 feet).
