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 beneath the instrument panel on the driver side of the vehicle. Refer to MODULE, BODY CONTROL (BCM), DESCRIPTION .
- Electronic Vehicle Information Center - The Electronic Vehicle Information Center (EVIC) includes the EVIC switches and the U-Connect Touch™ screen module in the Integrated Center Stack (ICS) located in the center stack area of the instrument panel. Refer to CENTER, ELECTRONIC VEHICLE INFORMATION, DESCRIPTION .
- Fuel Door Lock/Unlock - The fuel door locks and unlocks with the master power lock switch.
- Power Lock Motors - A reversible electric power lock motor is integral to the latch of each front and rear door, the fuel door and the liftgate.
- Power Lock Switches - A power lock switch is integral to the switch module located on the forward end of the armrest of each front door inside trim panel.
These components and their controls are combined to provide the following power lock system central locking and unlocking features:
- Customer Programmable Features - The EVIC switches allow the vehicle operator to set or change the power lock system Customer Programmable Features through the display.
- Door Lock Inhibit - Prevents locking the doors using a power door lock switch or the Lock button of the Remote Keyless Entry (RKE) system transmitter (also known as the FOB with Integrated Key/FOBIK) if the key is in the ignition and the driver side front door is open.
- 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.
Hardwired circuitry connects the power lock system components to the electrical system of the vehicle. These hardwired 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 appropriate SYSTEM WIRING DIAGRAMS and pin-out and location views for the various wire harness connectors, splices and grounds.
