Description & Operation: Notes

WARNING: Vehicles are equipped with air bag supplemental restraint system. Before attempting any repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in AIR BAG RESTRAINT SYSTEMS article.

CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

The remote control door lock receiver system allows the driver to use a hand held transmitter in order to unlock the driver's door, unlock all of the doors, lock all of the doors and open the rear compartment lid.

The range of the transmitter is about 7 m (23 ft). If the transmitter range decreases below this distance the transmitter battery may need replacement. See TRANSMITTER BATTERY under REMOVAL & INSTALLATION. Ambient conditions and other operating parameters may affect the maximum range of the transmitter.

Anonymous radio signal transmissions may create interference. This interference may decrease the range of the transmitter or disable operation completely. Attach the door lock key (oval head) to the ring on the transmitter in order to use the key as necessary.

Using the transmitter to unlock the driver's door or luggage compartment lid turns on the interior lamps. The interior lamps remain on for approximately 40 seconds or until the ignition switch is moved to the RUN position.

Door jamb switches are mounted on the front door. A switch that is mounted on the door handle controls the interior lamps. Four door models use door jamb switches on the front and the rear doors. The door jamb switches control the interior lamps when a rear door is open. The remote control door lock receiver turns on the interior lamps when the unlock or luggage compartment lid buttons on the transmitter are pressed.

Serial data is transmitted on a radio frequency carrier signal at 315 MHz. The signal is transmitted from the transmitter to the remote control door lock receiver when pressing the lock, unlock or luggage compartment lid release buttons on the transmitter.

The transmitter is resistant to shock, dust, moderate temperature changes, moisture and most common household and automotive fluids.

The remote control door lock receiver is located in the left inner wheel house panel of the luggage compartment. The following information appears on the module:
