instrument panel near the upper windshield opening header and is controlled by the courtesy lamp circuit. Front Dome/Reading Lamps (1) - Optional front seat driver side and passenger side dome/reading lamps located on the headliner above the instrument panel near the upper windshield header are controlled by both the courtesy lamp circuit and independent push button switches adjacent to each lamp. Rear Dome Lamp (2) - A rear dome lamp is optional equipment on vehicles manufactured for domestic markets. This lamp is located near the center of the headliner over the rear seating area and is controlled by the courtesy lamp circuit. On vehicles manufactured for certain export markets where an intrusion system is a required feature of the Vehicle Theft Security System (VTSS), a rear dome lamp is located near the center of the headliner over the rear seating area. This dome lamp houses an integral Intrusion Transceiver Module (ITM) and is controlled by the courtesy lamp circuit.

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 except the automatic transmission gear selector bezel lamp 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.

The optional automatic transmission gear selector bezel lamp is located on the left side of the gear selector lever mechanism just beneath the bezel on the forward end of the center floor console. This lamp has a replaceable incandescent bulb.

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

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. Refer to Electrical/Instrument Cluster -Description . Left Multi-Function Switch - The left (lighting) multi-function switch is located on the steering column, just below the steering wheel. A control sleeve on the control stalk that extends from the left side of the switch is used to select the panel lamps dimmer lighting level or the courtesy lamp circuit operating mode. Refer to Electrical/Lamps/Lighting - Exterior/SWITCH, Multifunction - Description . Liftgate Ajar Switch - A liftgate ajar switch is integral to the latch mechanism of the liftgate. 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. Refer to Electrical/Electronic Control Modules/MODULE, Steering Column - 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.

OPERATION

OPERATION

The lamps of the interior lighting system can be divided into two general classifications based upon the circuit that controls their operation: The courtesy lamp circuit, or the panel lamps dimmer circuit. Following are paragraphs that briefly describe the operation of each of these interior lighting circuits.

The lamps and the hard wired circuits between components related to the interior lighting system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the interior lighting system or the electronic controls or communication between modules and other devices that provide some features of the interior lighting system. The most reliable, efficient, and accurate means to diagnose the interior lighting system or the electronic controls and communication related to interior lighting system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

COURTESY LAMP CIRCUIT

The courtesy lamp circuit includes the front dome or map/reading lamps located on the headliner near the center of the windshield opening upper header, the cargo lamp or cargo lamp/flashlight located on the headliner near the center of the upper liftgate opening header, an optional rear dome lamp on the headliner near the center over the rear seating positions and, on vehicles manufactured for certain markets where an intrusion system is required equipment, a combination rear dome lamp/intrusion module unit on the headliner near the center over the rear seating positions.

The lamps in the courtesy lamp circuit are provided with battery voltage and ground by the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) using internal drivers through a courtesy lamp driver circuit and two ground circuits based upon hard wired inputs from the door ajar switches and the liftgate ajar switch. The EMIC also uses electronic left multi-function switch and ignition switch status message inputs received from the Steering Control Module (SCM) over the Local Interface Network (LIN) data bus to control these outputs.

After all of the ajar switch inputs to the EMIC transition to open, the EMIC will keep the courtesy lamps illuminated for about 30 seconds, then fade the lamps to OFF (theater dimming) over about 3 seconds. The EMIC also provides courtesy lamp operation based upon the electronic left multi-function switch statusmessages received from the SCM, and provides an illuminated entry feature in response to certain electronic message inputs received from the Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless Control Module/WCM) and the Occupant Restraint Controller (ORC) over the Controller Area Network (CAN) data bus. A courtesy lamp DEFEAT mode based upon an electronic left multi-function switch status message received from the SCM will cause the EMIC to override normal courtesy lamp operation based upon any ajar switch inputs.

For those lamps in the courtesy lamp circuit with independent switching such as the optional front map/reading


a


lamps, the EMIC provides a second battery feed to the switches using another internal driver through a separate courtesy lamp load shed circuit. The EMIC provides a battery saver (load shedding) feature for all courtesy lamps, which will automatically turn these lamps OFF if they are left ON for more than about eight minutes with the ignition switch in the OFF position.

PANEL LAMPS DIMMER CIRCUIT

The panel lamps dimmer circuit actually includes several circuits. These circuits control the illumination and dimming level of the heater-air conditioner controls, the four-wheel drive selector switch and the automatic transmission gear selector bezel lamp. All lamps in the panel lamps dimmer circuits are provided a path to ground at all times through a hard wired ground circuit. These lamps are illuminated by a 12-volt Pulse Width Modulated (PWM) output of the EMIC through the panel lamps dimmer circuit.

This shared PWM output synchronizes the selected illumination intensity level of all of the lamps in the panel lamps dimmer circuits. The EMIC uses electronic left multi-function switch status and dimming levelmessage inputs received from the SCM over the LIN data bus. The SCM sends the proper left multi-function switch status and dimming level messages based upon the exterior lighting selection of the control knob and the dimming level selection of the control sleeve on the left multi-function switch control stalk.

The EMIC, the instrument panel switch pod and the radio use the dimming level messages from the SCM to control the illumination intensity of their own back lighting and controls. In addition, when the control sleeve of the left multi-function switch is moved to the PARADE (or funeral) mode detent position, all of the Vacuum Fluorescent Display (VFD) units in the vehicle are illuminated at their full intensity levels for increased visibility when the vehicle is driven during daylight hours with the exterior lights turned ON. The PARADE mode has no effect on the illumination intensity of incandescent panel lamps.

wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

NOTE: When diagnosing the interior lighting circuits, remember that high generator output can burn out bulbs rapidly and repeatedly; and, that dim or flickering bulbs can be caused by low generator output or poor battery condition. If one of these symptoms is a problem on the vehicle, be certain to diagnose the battery and charging system, then repair as necessary.

NOTE: A good ground is necessary for proper lighting operation. If a lighting problem is being diagnosed that involves multiple symptoms, systems, or components, the problem can often be traced to a loose, corroded, or open ground.

Fig. 2: Dual-Purpose Cargo Lamp ComponentsCourtesy of CHRYSLER LLC

An optional dual-purpose cargo lamp (1) includes a removable and rechargeable flashlight (5). The flashlight is encased within a molded plastic housing, which is secured within the cargo lamp housing by two tabs on the end opposite the clear flashlight lens and a push-push type latch mechanism. The cargo lamp remains functional with or without the flashlight installed in the lamp housing.

The flashlight is powered by a rechargeable and replaceable lithium battery. A momentary switch on the flashlight electronic circuit board is actuated by a plastic push button (3) located on the side of the flashlight housing. When the flashlight is turned ON it illuminates two clear Light Emitting Diode (LED) units (2) to create a wide and bright light beam. A red LED unit (4) on the side of the flashlight housing behind the push button illuminates as the battery becomes discharged to indicate that the unit requires recharging.

The incandescent cargo lamp bulb, the cargo lamp lens, the flashlight battery and the flashlight unit are each available for separate service replacement. If any other component of the lamp or the flashlight are damaged or ineffective, the complete cargo lamp or flashlight unit must be replaced.

OPERATION

OPERATION

The rechargeable lithium battery within the flashlight automatically recharges while the flashlight is nested in its receptacle within the cargo lamp housing and the ignition switch is in the ON or START positions. The flashlight has a pair of electrical contacts that mate with contacts within the cargo lamp housing that provide a source of recharging current regardless of whether the cargo lamp is illuminated. The red Light Emitting Diode (LED) unit on the side of the flashlight behind the ON-OFF push button illuminates when the charge of the flashlight battery is becoming depleted.

The flashlight is removed from the cargo lamp housing by pushing it momentarily upward at the depression


a


marked PUSH on the flashlight, then releasing it and swinging it downward far enough to disengage two slots on the right end of the flashlight from two tabs within the cargo lamp housing. When the flashlight is removed from its receptacle in the cargo lamp housing, it can be used as an auxiliary light source in emergencies or other situations. The flashlight is turned ON or OFF by momentarily depressing and releasing the ON-OFF push button on the side of the flashlight housing. Reverse the removal procedure to restore the flashlight to the cargo lamp housing and to recharge the flashlight battery.

SWITCH, DOOR AJAR

DESCRIPTION

DOOR

This vehicle has four door ajar switches, one for each door. Each switch is concealed within and integral to its respective door latch unit. The switches are momentary leaf contact-type units that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector on each door latch connects the door ajar switch to the vehicle electrical system through its respective door wire harness.

The door ajar switches cannot be adjusted or repaired and, if ineffective or damaged, the door latch unit must be replaced. Refer to Body/Door - Front/LATCH, Door - Removal or refer to Body/Doors - Rear/LATCH, Door - Removal .

LIFTGATE

A liftgate ajar switch is standard equipment on this vehicle. The switch is concealed within and integral to the liftgate latch unit. The switch is a momentary leaf contact-type unit that is actuated by the liftgate latch


a


mechanism. An integral connector receptacle on the liftgate latch connects the liftgate ajar switch to the vehicle electrical system through the liftgate wire harness.

The liftgate ajar switch cannot be adjusted or repaired and, if ineffective or damaged, the liftgate latch unit must be replaced. Refer to Body/Decklid/Hatch/Liftgate/Tailgate/LATCH - Removal .

OPERATION

DOOR

The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is closed and properly latched, its door ajar switch is an open circuit. When a door is open or only partially latched, the door ajar switch is a closed circuit. The door ajar switches are hard wired in series between a body ground and the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). The EMIC reads the hard wired door ajar switch inputs through internal pull-ups, then uses these inputs to control many electronic functions and features of the vehicle. The EMIC also sends electronic door ajar switch status messages over the Controller Area Network (CAN) data bus.

The door ajar switches as well as the hard wired inputs and outputs of the switches may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information.

LIFTGATE

The liftgate ajar switch is actuated by the liftgate latch mechanism. When the liftgate is closed and properly latched, its liftgate ajar switch is an open circuit. When the liftgate is open or only partially latched, the liftgate ajar switch is a closed circuit. The liftgate ajar switch is hard wired in series between a body ground and the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). The EMIC reads the hard wired liftgate ajar switch input through an internal pull-up, then uses this input to control many electronic functions and features of the vehicle.

The liftgate ajar switch as well as the hard wired inputs and outputs of the switch may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information.
