DESCRIPTION

The exterior lighting system for this vehicle includes the following exterior lamp units:

- Center High Mounted Stop Lamp - A standard equipment Center High Mounted Stop Lamp (CHMSL) is centered in the upper rear window opening of Chrysler 4-door models, or in the center of the deck lid of Chrysler convertibles and all Dodge models at the rear of the vehicle.
- Front Fog Lamps - Standard equipment front fog lamp units are mounted near each outboard end of the front fascia, below the front lamp units.
- Front Lamp Units - A front lamp unit with a single bi-halogen projector headlamp bulb (Chrysler) or two, single-filament headlamp bulbs (Dodge) is located at each outboard side of the grille opening in the Front End Module (FEM).
- Headlamps - A standard equipment front headlamp unit is mounted to the front end sheet metal on each side of the grille opening of the MK74 - Patriot model. These lamps are integrated into the front lamp units of the MK49 - Compass model.
- License Plate Lamps - Two standard equipment rear license plate lamp units are secured to the rear fascia assembly, in the top of the license plate tub formation.
- Rear Lamp Units - A standard equipment rear lamp unit is mounted to the rear of each quarter panel on either side of the deck lid opening.

These exterior lighting lamp units and their controls are combined to provide the following exterior lighting features:

- Automatic Headlamps - Vehicles with the automatic headlamps option are equipped with a unique left multi-function switch that includes an A (Automatic) position and have an automatic headlamp sensor to sense ambient light levels. The automatic headlamp sensor is integral to the sun load sensor located on the top of the instrument panel. Sun Sensor - Description.
- 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 the lens and multiple Light-Emitting Diode (LED) units of each rear lamp unit. The brake lamps also include the red lens and multiple LED units of the CHMSL.
- Daytime Running Lamps - Daytime Running Lamps (DRL) are standard equipment on vehicles manufactured for sale in Canada. Chrysler vehicles with DRL enabled illuminate the turn signal bulb in each front lamp unit to serve as the DRL. Dodge vehicles with DRL enabled modulate the high beam headlamp bulb 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 optional equipment front fog lamps include the clear bulb, reflector and incorporate a projector lens.
- Hazard Warning Lamps - The hazard warning lamps include the bulbs, reflectors and lenses of each front lamp unit and the multiple LED units and lenses of the rear lamp units 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 - On Chrysler models the headlamps include a single halogen bulb for low or high beam headlamps and a projector lens. An electric motor and mechanism internal to each front lamp unit closes a shutter for low beams and opens the shutter for high beams. On Dodge models the headlamps include two single filament halogen bulbs in each front lamp unit, one low beam and one high beam. All headlamp systems also include an adjustable reflector and clear lens integral to each front lamp unit.
- 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 - On Chrysler models the front park lamps include a multiple LED unit strip near the top of each front lamp unit. On Dodge models the front park lamps include the bulbs and lenses of the park lamp compartment in both front lamp units. On all vehicles the front lamp units also include the front side marker lamps and amber reflectors. The rear park lamps include the lens and multiple LED units of each rear lamp unit as well as the bulbs and clear lenses of the rear license plate lamps.
- Turn Signal Lamps - The front turn signal lamps include an amber bulb, a reflector, and a clear lens that are integral to each front lamp unit. The rear turn signal lamps include the lens and multiple LED units of 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 between the radio and the heater and air conditioner controls in the center stack area of the instrument panel.
- 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 between the radio and 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. Totally Integrated Power Module (TIPM) - Description.

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.
