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 passenger side of the vehicle. Refer to MODULE, BODY CONTROL (BCM), DESCRIPTION .
- Deck Lid Release Switch - A switch on the instrument panel to the left of the steering column will unlatch the deck lid only when the automatic transmission gear selector is in the PARK position, or when the manual transmission vehicle speed is below 8 km/h (5 mph).
- Door Modules - The Driver Door Module (DDM) and Passenger Door Module (PDM) are located on their respective driver and passenger front door hardware module carriers and are concealed behind the front door inside trim panels. Refer to MODULE, DOOR (DDM/PDM), 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 .
- Power Lock Motors - A reversible electric power lock motor is integral to the latch of each front and rear door and the deck lid.
- 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:
- Automatic Door Locking - Automatic door locking (also known as rolling door locks) automatically locks any unlocked door when the vehicle speed exceeds about 24.1 km/h (15 mph). This is a Customer Programmable feature.
- Automatic Door Unlocking - Automatic door unlocking (also known as automatic unlock doors on exit) automatically unlocks the doors after they were automatically locked when the vehicle speed exceeded about 24.1 km/h (15 mph), the vehicle speed has returned to zero, the transmission shift lever is in the Neutral or Park positions and the driver side front door is opened. 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 switches allow the vehicle operator to set or change the power lock system Customer Programmable Features through the U-Connect Touch™ screen module EVIC 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 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.
