Power Locks - Description

DESCRIPTION

A power operated door and liftgate lock system is standard factory-installed equipment on this vehicle. The power lock system allows both doors and the liftgate to be locked or unlocked electrically. Locking or unlocking the vehicle using the power lock system can be accomplished by two different methods:

- Power Lock System - Operating the inside remote handle on the driver side front door inside trim panel will lock (handle pushed in) or unlock (handle pulled out) both doors and the liftgate.
- Remote Keyless Entry System - Depressing the Lock or Unlock button of the standard equipment Remote Keyless Entry (RKE) system transmitter can also be used to lock or unlock both doors and the liftgate.

Additional details of each of these subsystems and their components can be found in the subheadings and paragraphs that follow.

POWER LOCK SYSTEM

The power lock system includes the following major components, which are described in further detail elsewhere in this service information:

- Body Control Module - The Body Control Module (BCM) is located under the driver side end of the instrument panel in the passenger compartment. Body Control Module - Description.
- Electronic Vehicle Information Center - The Electronic Vehicle Information Center (EVIC) is a digital display integral to the Instrument Panel Cluster (IPC), which is located on the instrument panel in front of the driver. Electronic Vehicle Information Center - Description.
- Instrument Panel Cluster - The Instrument Panel Cluster (IPC) is located on the instrument panel in front of the driver. Instrument Cluster - Description.
- Power Lock Motors - A reversible electric power lock motor is integral to the latch of each door and the liftgate.
- Power Lock Switch - A power lock switch is integral to the driver side door latch located within the driver side door and concealed behind the door inside trim panel.

These components and their controls are combined to provide the following power lock system central locking and unlocking features:

- Automatic Door Locking - Automatic door locking (also known as rolling door locks) automatically locks any unlocked door when the vehicle speed exceeds about 20 kilometers per hour (12 miles per hour). This is a Customer Programmable feature.
- Customer Programmable Features - The vehicle operator interfaces with the BCM, which is the power lock system controller, using the EVIC. EVIC switch push buttons located on the right side of the Instrument Panel Cluster (IPC) bezel allow the vehicle operator to set or change the power lock system Customer Programmable Features through the EVIC display.
- Enhanced Accident Response System - In the event of a vehicle impact that causes airbag deployment but leaves vehicle electrical power intact, the Enhanced Accident Response System (EARS) automatically turns OFF the supply of fuel to the engine, turns ON the interior courtesy lamps, turns ON the hazard warning flashers and unlocks the doors after the vehicle speed has returned to zero. This helps emergency responders in their efforts to render the appropriate assistance. The courtesy lamps and hazard flashers remain ON as long as the battery has power or until the key is removed from the ignition.
- Illuminated Entry - Automatic illumination of the interior courtesy lamps when the vehicle is unlocked using the power lock system.

Hard wired circuitry connects the power lock system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the power lock system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.

REMOTE KEYLESS ENTRY SYSTEM

The Remote Keyless Entry (RKE) system is standard factory-installed equipment on this vehicle. The RKE system includes the following major components, which are described in further detail elsewhere in this service information:

- Body Control Module - The Body Control Module (BCM) is the RKE system control module and RF receiver located under the driver side end of the instrument panel in the passenger compartment. Body Control Module - Description.
- Remote Keyless Entry System Transmitter - The Remote Keyless Entry (RKE) system transmitter is the battery powered, wireless and portable Radio Frequency (RF) user controller for all of the features of the RKE system.

These components and their controls are combined to provide the following RKE system features:

- Programming Additional Transmitters - Two RKE transmitters are shipped with the vehicle from the factory, but the RKE system can retain the vehicle access codes of up to a total of eight transmitters. The transmitter codes are retained in the RKE system controller memory, even if the battery is disconnected. If a FOBIK is ineffective, lost or an additional FOBIK is desired, new transmitter vehicle access codes can be programmed into the system using a diagnostic scan tool.
- Remote Liftgate Unlocking - Depressing the Liftgate or Trunk button of the RKE transmitter once while within transmitter range will unlock the liftgate of the vehicle.
- Remote Locking - Depressing the Lock button of the FOBIK while within transmitter range will lock all of the vehicle doors and the liftgate.
- Remote Unlocking - Depressing the Unlock button of the RKE transmitter while within transmitter range will unlock the vehicle and activate the Illuminated Entry System.
- Vehicle Theft Security System Arming - Depressing the Lock button of the RKE transmitter while within transmitter range will arm the VTSS in addition to activating the remote locking feature.Vehicle Theft Security System - Description.
- Vehicle Theft Security System Disarming - Depressing the Unlock button of the RKE transmitter while within transmitter range will disarm the VTSS in addition to activating the remote unlocking feature.Vehicle Theft Security System - Description.

Hard wired circuitry connects many of the RKE system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the RKE system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators.
