General information

Power lock system

The power lock system allows all four doors and the liftgate to be locked or unlocked electrically by operating the switch on either front door trim panel.

The power lock system operates on non-switched battery current supplied through a fuse in the junction block so that the system remains functional, regardless of the ignition switch position.

The power lock system includes the power lock switches on each front door trim panel, and the power lock motors inside each door and the liftgate.

The power lock control circuitry and the power lock and unlock relays are integral to the high-line version of the Central Timer Module (CTM), which is mounted under the instrument panel.

Following are general descriptions of the major components in the power lock system. Refer to the owner's manual in the vehicle glove box for more information on the features, use and operation of the power lock system.

Remote keyless entry system

The Remote Keyless Entry (RKE) system is a radio frequency system that allows the use of a remote battery- powered radio transmitter to control the power lock system. On vehicles with the RKE option, the power locks can be operated by depressing the Lock or Unlock buttons of the RKE transmitter. If the vehicle is so equipped, the RKE transmitter also arms and disarms the factory-installed vehicle theft alarm. Refer to Group 8Q - Vehicle Theft/Security Systems for more information on the optional vehicle theft alarm.

The RKE system includes an illuminated entry feature, which turns on the courtesy lamps for a timed interval (about thirty seconds), when the power door locks are unlocked using the RKE transmitter. The RKE system for this vehicle also features a programmable horn chirp, a programmable driver door unlock, a programmable rolling door lock, and a panic feature.

The programmable horn chirp feature allows the enabling or disabling of the horn chirp request that the RKE receiver issues as an audible indication that a valid Lock signal has been received from the RKE transmitter. The programmable driver door unlock feature allows one press of the RKE transmitter Unlock button to unlock just the driver door, and a second press within five seconds to unlock all doors and the liftgate. If disabled, one press of the RKE transmitter Unlock button will unlock all doors and the liftgate. The rolling door lock feature will lock all of the doors and the liftgate above a vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour).

These features can be enabled or disabled using a DRB scan tool as described in the proper Diagnostic Procedures manual. These features can also be enabled/disabled using the customer programmable feature. See the owner's manual in the vehicle glove box for more information on the customer programmable feature.

The panic feature allows the vehicle operator to cause the horn to pulse, the headlights to flash and the courtesy lamps to light for about three minutes by depressing the Panic button on the RKE transmitter.

A second depression of the Panic button, or a vehicle speed of about 24 kilometers-per-hour (15 miles-per-hour) will turn off the panic event prior to the expiration of the automatic three minute timer.

The RKE system can retain the vehicle access codes of up to four RKE transmitters. The transmitter codes are retained in RKE system memory, even if the battery is disconnected. If a transmitter is faulty or is lost, new transmitter vehicle access codes can be programmed into the system using a DRB scan tool as described in the proper Diagnostic Procedures manual. If one functional transmitter is available, up to three additional transmitters can be programmed using the customer programmable feature.

See the owner's manual in the vehicle glove box for more information on the customer programmable feature.

The RKE system consists of a driver unlock relay, a headlamp (or security) relay, a horn relay, a key fob remote radio transmitter and a radio receiver with program logic, which is integral to the high-line version of the Central Timer Module (CTM).
