2003 jeep liberty dashlights not working1/10/2024 Refer to the appropriate diagnostic information.2004 jeep grand cherokee fan relay location. What could cause it is a chafed wire in about 50 feet of wiring harness, corroded bulb sockets, corroded plugs in the harness, improperly wired aftermarket. However, proper testing of the PWM output of the EMIC and the electronic dimming level messages sent by the BCM over the PCI data bus requires the use of a DRBIIIt scan tool. ![]() 2005-2008 JEEP GRAND CHEROKEE WK FACTORY SERVICE MANUAL + 3 Jeep Liberty (KK) (2008-2012). The hard wired multi-function switch and EMIC panel lamps dimmer inputs and outputs may be diagnosed using conventional diagnostic methods. It will most likely be problems related to your transmission. The BCM monitors the request for this mode from the multi-function switch, then sends an electronic dimming level message to the over the PCI data bus to illuminate all VFD units in the vehicle at full (daytime) intensity for easier visibility when driving in daylight with the exterior lighting turned on. In addition, the control ring on the left (lighting) control stalk of the multi-function switch has a Parade Mode position to provide a parade mode. The BCM also sends electronic dimming level messages over the PCI data bus to other electronic modules in the vehicle to control and synchronize the illumination intensity of their VFD units to that of the EMIC VFD unit. The cluster illumination lamps are grounded at all times. This PWM output is used to illuminate the cluster illumination lamps and the VFD on the EMIC circuit board, and provides a PWM output on the hard wired fused panel lamps dimmer switch signal circuit to control and synchronize the illumination intensity of other incandescent illumination lamps in the vehicle. Based upon the dimming level message, the EMIC then converts the battery current input to the appropriate 12-volt Pulse Width Modulated (PWM) output. The EMIC receives the electronic dimming level message from the BCM, and a battery current input from the energized park lamp relay on the hard wired fused park lamp relay output. In response to that input, the BCM provides a control output to energize the park lamp relay and an electronic dimming level message to the EMIC over the Programmable Communications Interface (PCI) data bus based upon internal programming. The Body Control Module (BCM) monitors a resistor multiplexed input from the multi-function switch on a panel lamps dimmer switch mux circuit. The illumination intensity of these lamps is adjusted when the interior lighting control ring on the left control stalk of the multifunction switch is rotated (down to dim, up to brighten) to one of six available minor detent positions. The fuse panel in the side of the dash when you open the drivers door is the. ![]() The fuses are also marked but the diagram in the manual is clearer. Check in your owners manual and find the fuse diagram. when I turn the headlights on, I still head the electrical click in the passenger compartment - so I figure that's a good sign. the fog lights work, as do the signal lights. I checked the fuses (4 adn 5 I think) they're good. Last night both headlights stopped working - during a drive. The ElectroMechanical Instrument Cluster (EMIC) has several illumination lamps that are illuminated when the exterior lighting is turned on with the headlamp switch. I had my dash instrument cluster lights and the right rear tail lights go out all at once. Hi folks, Looking for some advice where to start first. the part about the dimmer switch is in bold Most of the information I provided is not what you are looking for but may become important. Maryellen Mcgee darn Jeep could not have made this more complicated.
