These exterior lighting lamp units and their controls are combined to provide the following exterior lighting features:
- Backup Lamps - The backup (or reverse) lamps include a clear bulb, reflector and clear lens that are integral to each rear lamp unit.
- Brake Lamps - The brake (or stop) lamps include a clear bulb, reflector and red lens that are integral to each rear lamp unit, and the red lens and multiple Light-Emitting Diode (LED) units of the CHMSL.
- Daytime Running Lamps - Daytime Running Lamps (DRL) are standard equipment on vehicles manufactured for sale in Canada and optional on vehicles manufactured for the United States. Vehicles with DRL enabled illuminate the high beam filament of each headlamp bulb (except Patriot with Trail-Rated option for the United States market, which uses the low beam filament) at a reduced intensity to serve as the DRL.
- Exterior Lamp Fail-Safe Operation - The ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) and the Totally Integrated Power Module (TIPM) provide a fail-safe feature which will automatically turn ON the low beam headlamps and all park lamps when the ignition switch is in the ON position and there is no detected input from the Steering Control Module (SCM), or when there is no communication over the Local Interface Network (LIN) or Controller Area Network (CAN) data buses.
- Exterior Lamp Load Shedding - The TIPM provides a battery saver feature which will automatically turn OFF all exterior lamps that remain ON with the ignition switch in the LOCK position after a timed interval of about eight minutes.
- Front Fog Lamps - The standard equipment front fog lamps include the clear bulb, reflector and clear lens of each adjustable front fog lamp unit.
- Hazard Warning Lamps - The hazard warning lamps include the bulbs, reflectors and lenses of each lamp in the right and left, front and rear turn signal circuits.
- Headlamp Delay - The standard equipment low or high beam headlamps remain illuminated for a customer-programmable delay period of 0 (disabled), 30, 60 or 90 seconds when the headlamps are turned OFF after the ignition switch has been turned to the OFF position.
- Headlamps - The headlamps include a single, dual filament halogen bulb, an adjustable reflector and a clear lens integral to each headlamp unit.
- Headlamp Leveling - Headlamp leveling is available only in certain markets where it is required equipment. A headlamp leveling actuator motor on each headlamp unit and a headlamp leveling switch integral to the switch pod in the instrument panel center stack allow the headlamp beam pattern to be adjusted by the vehicle operator from the interior of the vehicle to compensate for passenger or cargo loads.
- Optical Horn - Also known as flash-to-pass, the beam selection function of the left (lighting) multi-function switch control stalk has a momentary intermediate position that allows the headlamp high beams to be flashed momentarily, without changing the headlamp beam selection.
- Park Lamps - The front park lamps include the amber bulbs, reflectors and clear lenses integral to each front park/turn lamp unit and, if the vehicle is so equipped, the clear position lamp bulb integral to each headlamp unit. The rear park lamps include the clear bulbs, reflectors and red lenses integral to each rear lamp unit as well as the bulbs and lenses of the rear license plate lamps.
- Rear Fog Lamps - Rear fog lamps are available only in certain markets where they are required equipment. The rear fog lamps include a clear bulb and a red lens and reflector that are integral to each rear lamp unit.
- Turn Signal Lamps - The front turn signal lamps include an amber bulb, a reflector and a clear lens that are integral to each front park/turn lamp unit. In certain markets where they are required, the repeater lamps on each front fender will also be included in the front turn signal circuits. The rear turn signal lamps include either an amber bulb, a reflector and a clear lens that are integral to each rear lamp unit.
Other components of the exterior lighting system for this vehicle include:
- Backup Lamp Switch - A plunger-type backup lamp switch is installed through the transmission housing of vehicles equipped with a manual transmission and is actuated by the shifter mechanism within the transmission when REVERSE gear is selected. On vehicles with an optional automatic transmission a stand-alone Transmission Range Sensor (TRS) performs the backup lamp switch function.
- Brake Lamp Switch - A plunger-type brake lamp switch is located on the brake pedal support bracket under the instrument panel and is actuated by the brake pedal arm when the brake pedal is depressed.
- Clockspring - The clockspring includes an integral turn signal cancel cam, which provides automatic turn signal cancellation as the steering wheel is rotated back to its centered position following a vehicle turning maneuver. The clockspring is located near the top of the steering column, directly beneath the steering wheel. Clockspring - Description.
- Hazard Switch - A latching push button-actuated hazard switch is integral to the switch pod located just below the heater and air conditioner controls in the center stack area of the instrument panel.
- Headlamp Leveling Switch - A four mode push button-actuated headlamp leveling switch is integral to the switch pod located just below the heater and air conditioner controls in the center stack area of the instrument panel of vehicles manufactured for certain markets where the headlamp leveling feature is required.
- 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.
- Instrument Panel Switch Pod - The instrument panel switch pod contains the hazard switch and, on vehicles so equipped, the headlamp leveling switch. The switch pod is located just below the heater and air conditioner controls in the center stack area of the instrument panel. Instrument Cluster Switch Pod - Description.
- Left Multi-Function Switch - The left (lighting) multi-function switch is located on the steering column, just below the steering wheel. A control stalk that extends from the left side of the switch is used to select the turn signal lamps (right or left) and to select the headlamp beam (low, high or optical horn). A control knob on the control stalk is used to select the park lamps, headlamps or fog lamps.
- Park Brake Switch - A park brake switch is located on the park brake lever mechanism on the floor panel transmission tunnel between the two front seats.
- Steering Control Module - The Steering Control Module (SCM) is located within the left multi-function switch housing on the top of the steering column, just below the steering wheel. Steering Column Module - Description.
- Totally Integrated Power Module - The Totally Integrated Power Module (TIPM) is located in the engine compartment, near the battery. Description.
- Trailer Tow Wiring - Vehicles equipped with an optional Trailer Tow Prep package have a trailer tow wiring jumper harness, relay pack and an instruction card that are placed in the cargo area of the vehicle when it is shipped from the factory. This package also includes an additional fused B(+) circuit in the unibody wire harness behind the right D-pillar trim for a feed connection to the relay pack in the trailer tow wiring jumper harness.
Hard wired circuitry connects the exterior 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 exterior 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.
