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

The lamps of the interior lighting system can be divided into general classifications based upon the circuit that controls their operation: The courtesy lamp circuit, the reading lamps circuit and the panel lamps dimmer circuit. Following are paragraphs that briefly describe the operation of the courtesy lamps, reading lamps and panel lamps dimmer 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 courtesy lamps located under each outboard end of the instrument panel and, depending upon the selected vehicle options may include either the dome or map and reading lamps located in the overhead console near the windshield and on the roof rails adjacent to the rear outboard seating positions, the liftgate lamps located near each lower corner of the liftgate trim panel, the glove box lamp in the top of the glove box opening in the instrument panel and the vanity lamps located in the sun visors.

The lamps in the courtesy lamp circuit are provided with a path to ground at all times. The ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) controls the output of battery voltage for the courtesy lamps in this circuit based upon hard wired inputs from the headlamp switch and electronic message inputs from the ignition switch (also known as the Wireless Ignition Node/WIN) and the Totally Integrated Power Module (TIPM).

After all of the ajar switch inputs to the TIPM transition to open and the EMIC receives the appropriate electronic ajar switch status messages from the TIPM over the Controller Area Network (CAN) data bus, 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 a resistor multiplexed input from the interior lighting thumbwheel on the headlamp switch, and provides an Illuminated Entry feature in response to certain electronic ignition switch status message inputs received from the WIN and the Occupant Restraint Controller (ORC) over the CAN data bus. A resistor multiplexed courtesy lamp DEFEAT input from the interior lighting thumbwheel of the headlamp switch will cause the EMIC to override normal courtesy lamp operation.

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 10 minutes after the electronic ignition switch status message transitions to OFF. If any courtesy lamp input is received subsequent to a 10 minute load shed and prior to a new ignition cycle, the courtesy lamps will turn OFF after 90 seconds.

READING LAMP CIRCUIT

For those lamps on the courtesy lamp circuit with independent switching such as the reading lamps, the optional vanity lamps and the glove box lamp, the EMIC also provides a battery voltage output to those switches through a separate reading lamp circuit. The EMIC provides a battery saver (load shedding) feature for the reading lamp circuit as well as the courtesy lamp circuit, which will automatically turn these lamps OFF if they are left ON for more than about 10 minutes after the electronic ignition switch status message transitions to OFF. If any reading lamp input is received subsequent to a 10 minute load shed and prior to a new ignition cycle, the reading lamps will turn OFF after 90 seconds.

PANEL LAMPS DIMMER CIRCUIT

The panel lamps dimmer circuit actually includes several circuits. These circuits control the back lighting illumination and dimming level of the headlamp switch, the heater-air conditioner controls, the instrument panel switch pod, the four-wheel drive selector switch, the automatic transmission gear selector bezel lamp, the front door map pocket and remote inside handle lamps, as well as the center floor console cup holder and forward storage compartment lamps. 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 several panel lamps dimmer circuits.

This shared PWM output synchronizes the selected illumination intensity level of all the lamps in the panel lamps dimmer circuits. The EMIC uses hard wired inputs from the rotary exterior lighting control knob and interior lighting thumbwheel of the headlamp switch to determine when the exterior lighting is turned ON and the dimming level selection. Then the EMIC provides the appropriate PWM outputs through the panel lamps dimmer circuits as well as electronic dimming level messages over the CAN data bus to other electronic modules in the vehicle.

The EMIC, the instrument panel switch pod and the radio use the electronic dimming level messages to control the illumination intensity of their own back lighting, controls and display units. In addition, when the interior lighting thumbwheel of the headlamp switch is moved to the PARADE (or funeral) mode detent position, all of the electronic display units are illuminated at their full intensity levels for increased visibility when the vehicle is driven during daylight hours with the exterior lighting turned ON. The PARADE mode has no effect on the illumination intensity of incandescent panel lamps.

DIAGNOSIS AND TESTING

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.

The hard wired circuits between components related to the operation of 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 AND READING LAMP CIRCUITS

Note. As part of the exterior lighting fail-safe feature, upon ignition ON all of the panel lamps dimmer circuit lamps will illuminate at full intensity and the exterior park lamps and headlamp low beams will illuminate regardless of the headlamp switch position if the instrument cluster cannot detect an input from the headlamp switch, or if there is a loss of data bus communication.

PANEL LAMPS

Note. All illuminated controls on the instrument panel and elsewhere in the interior of the vehicle have either miniature incandescent bulbs or Light-Emitting Diode (LED) units that are soldered to internal circuit boards and are not serviceable.

Scheme 1

A removable and rechargeable flashlight (3) is encased within a molded plastic housing, which is secured within a bezel/charging station (2) at the back of the left quarter inner trim panel (1) by two tabs on the end opposite the clear flashlight lens and a push-push type latch mechanism. 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 located on the side of the flashlight housing. When the flashlight is turned ON it illuminates two clear Light Emitting Diode (LED) units to create a wide and bright light beam. A red LED unit 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 bezel/charging station unit, the flashlight battery and the flashlight unit are each available for separate service replacement. If any other component of the flashlight or bezel/charging station are damaged or ineffective, the complete flashlight unit or bezel/charging station unit must be replaced.

The rechargeable lithium battery within the flashlight automatically recharges while the flashlight is nested in its receptacle within the bezel charging station and the engine is running. The flashlight has a pair of electrical contacts that mate with contacts within the charging station that provide a source of recharging current. 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 bezel/charging station by pushing it momentarily at the depression marked PUSH on the flashlight housing, then releasing it and swinging it downward far enough to disengage two slots on the lower end of the flashlight from two tabs within the charging station. When the flashlight is removed from its receptacle in the bezel/charging station, it can be used as an auxiliary light source in emergencies or other situations where a portable light source is required. 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 bezel/charging station and to recharge the flashlight battery.

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 Totally Integrated Power Module (TIPM) on vehicles without the power liftgate option, or the Power LiftGate Module (PLGM) on vehicles with the power liftgate option. The TIPM or the PLGM 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 TIPM or the PLGM also sends electronic liftgate ajar switch status messages to other electronic modules in the vehicle over the Controller Area Network (CAN) data bus.

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.
