Interior Lighting - Description

DESCRIPTION

The interior lighting system for this vehicle includes both incandescent and Light Emitting Diode (LED) unit lighting on several separate circuits. The lamps in the interior lighting system include:

- Center Bezel Lamp - A standard center bezel lamp with a replaceable incandescent bulb is located on the underside of an opening in the instrument panel center bezel to illuminate the center console forward storage bin and is supplied voltage by the park lamp circuit to illuminate whenever the exterior lighting is turned ON.
- Center Floor Console Cup Holder Lamp - The cup holders in the center floor console include a standard equipment light pipe around their inside perimeter illuminated by an LED lamp unit to assist visibility at night. This lamp is controlled by the panel lamps dimmer circuit and illuminates whenever the exterior lighting is turned ON.
- Courtesy Lamps - Standard incandescent courtesy lamps are located under the right and left ends of the instrument panel, and are controlled by the courtesy lamp circuit.
- Glove Box Lamp - A standard incandescent glove box lamp with an integral plunger-actuated switch is located on the upper outboard corner of the glove box housing of the instrument panel and illuminates whenever the glove box is opened.
- Liftgate Lamp - Two standard incandescent liftgate lamps are located in the lower corners of the liftgate trim panel and are activated automatically whenever the liftgate is opened to illuminate the rear cargo area of the vehicle.
- Front Dome Lamps - Available front seat driver side and passenger side incandescent dome lamps are located behind a lens shared with the LED map/reading lamps in the overhead console. The dome lamps are controlled by the courtesy lamp circuit and by independent lens-actuated switches.
- Front Door Inside Remote Latch Handle Lamps - Front door trim panel inside remote latch handles on some models include an LED lamp unit to assist visibility at night. These lamps are controlled by the panel lamps dimmer circuit and illuminate whenever the exterior lighting is turned ON.
- Front Door Map Pocket Lamps - Front door trim panel map pockets on some models include an LED lamp unit to assist visibility at night. These lamps are controlled by the panel lamps dimmer circuit and illuminate whenever the exterior lighting is turned ON.
- Front Map/Reading Lamps - Standard front seat driver side and passenger side LED map/reading lamps are located behind a lens shared with the incandescent dome lamps in the overhead console. The map/reading lamps are controlled by the courtesy lamp circuit and by independent push button switches in the overhead console.
- Second And Third Row Dome Lamps - The standard incandescent second and third row seating dome lamps are controlled by the courtesy lamp circuit.
- Second And Third Row Map/Reading Lamps - Two standard LED map/reading lamps are located above both the second and third row seating in housings shared with the incandescent dome lamps in the headliner. The map/reading lamps are controlled by independent push button switches in the lamp housings.
- Rechargeable Flashlight - A removable twin-LED flashlight powered by rechargeable lithium batteries is mounted in a bezel/charging station located in the left quarter trim panel near the D-pillar in the cargo area of the vehicle.
- Vanity Lamps - An optional single intensity, incandescent vanity lamp is located on each side of a covered mirror on both the right and left sun visors, and is controlled by an integral vanity mirror cover-actuated switch.

Most controls on the instrument panel and elsewhere in the interior of the vehicle are illuminated by the panel lamps dimmer circuit for night visibility. All have miniature incandescent bulbs, Light-Emitting Diode (LED) units or a combination of the two lighting types that are soldered to internal circuit boards and are not serviceable.

Other components of the interior lighting system for this vehicle include:

- Dimmer Module - A dimmer module is located on the left side of the instrument panel, below and outboard of the steering column just inboard from the headlamp switch. The dimmer module features a vertical thumbwheel for selecting the panel lamps dimming level, a PARADE mode to illuminate all Vacuum Fluorescent Display (VFD) units at full brightness for visibility when driving in daylight with the exterior lighting turned ON. There are also detent positions to turn ON all interior courtesy lighting, and a DEFEAT position that overrides door ajar switch control of interior lighting.
- Door Ajar Switches - A door ajar switch is integral to the door latch mechanism of each front and rear door.
- Instrument Cluster - The ElectroMechanical Instrument Cluster (EMIC) is also known as the Cab Compartment Node (CCN) in this vehicle. The EMIC/CCN is located in the instrument panel above the steering column opening, directly in front of the driver. Instrument Cluster - Description.
- Liftgate Ajar Switch - A liftgate ajar switch is integral to the latch mechanism of the liftgate.
- Totally Integrated Power Module - The Totally Integrated Power Module (TIPM) is located in the engine compartment. Description.

Hard wired circuitry connects the interior lighting 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 interior lighting 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.
