the remaining switches feature momentary operation.

Four screws secure the switch to the back of the instrument panel center bezel through integral mounting tabs
that are molded into each corner of the switch housing. The back of the switch housing has an integral
connector receptacle containing terminal pins that connect the switch to the vehicle electrical system through a
dedicated take out and connector of the instrument panel wire harness.

Panel lamps dimmer controlled illumination lamps integral to the circuit board within the switch provide back
lighting for visibility at night, but these lamps are not serviceable. The individual switches in the instrument
panel switch pod cannot be repaired and are not serviced separately. If any component within the switch pod is
ineffective or damaged, the entire switch pod unit must be replaced.

OPERATION

For information covering details of operation for the individual switches or indicator contained within the
instrument panel switch pod, refer to the specific service information covering the system to which that switch
or indicator belongs.

REMOVAL

INSTRUMENT PANEL SWITCH POD

WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable
the Supplemental Restraint System (SRS) before attempting any steering
wheel, steering column, airbag, Occupant Classification System (OCS),
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.

LOW FUEL INDICATOR

DESCRIPTION

LOW FUEL INDICATOR

2007 ACCESSORIES AND EQUIPMENT Instrument Cluster - Service Information - Nitro

A low fuel indicator is standard equipment on all instrument clusters. The low fuel indicator is located above
the fuel gauge needle hub on the cluster overlay, to the left of the speedometer.

The low fuel indicator consists of a stencil-like cutout of the International Control and Display Symbol icon for
Fuel in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the
indicator from being clearly visible when it is not illuminated. An amber Light Emitting Diode (LED) behind
the cutout in the opaque layer of the overlay causes the indicator to appear in amber through the translucent
outer layer of the overlay when it is illuminated from behind by the LED, which is soldered onto the instrument
cluster electronic circuit board.

The low fuel indicator is serviced as a unit with the instrument cluster.

OPERATION

LOW FUEL INDICATOR

The low fuel indicator gives an indication to the vehicle operator when the level of fuel in the fuel tank becomes
low. This indicator is controlled by a transistor on the instrument cluster circuit board based upon cluster
programming and electronic fuel level messages received by the cluster from the Totally Integrated Power
Module (TIPM) over the Controller Area Network (CAN) data bus.

The low fuel indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster logic
circuit, and that logic will only allow this indicator to operate when the instrument cluster receives a battery
current input on the fused ignition switch output (run-start) circuit. Therefore, the LED will always be OFF
when the ignition switch is in any position except ON or START. The LED only illuminates when it is provided
a path to ground by the instrument cluster transistor. The instrument cluster will turn ON the low fuel indicator
for the following reasons:



Bulb Test - Each time the ignition switch is turned to the ON position the low fuel indicator is
illuminated for about three seconds as a bulb test.



Less Than 11 Percent Tank Full Message - The TIPM provides a constant current source to the fuel
level sending unit and monitors a return input on a fuel level sense circuit. The resistance through the fuel
level sending unit increases as the fuel level rises and decreases as the fuel level falls causing changes in
the fuel level sense input voltage. The TIPM then sends the appropriate electronic fuel level messages to
the cluster. Each time the fuel level messages to the cluster indicate the fuel tank is about 11 percent full
or less for 10 consecutive seconds and the vehicle speed is zero, or for 60 consecutive seconds and the
vehicle speed is greater than zero, the gauge needle is moved to the appropriate position on the gauge
scale, the low fuel indicator is illuminated, and a single chime tone is sounded. The low fuel indicator
remains illuminated until the fuel level messages indicate that the fuel tank is greater than about 14
percent full for 10 consecutive seconds and the vehicle speed is zero, or for 60 consecutive seconds and
the vehicle speed is greater than zero, or until the ignition switch is turned to the OFF position, whichever
occurs first. The chime tone feature will only repeat during the same ignition cycle if the low fuel
indicator is cycled OFF and then ON again by the appropriate messages from the TIPM.



Less Than Empty Stop Message - Each time the cluster receives a fuel level message indicating the fuel
level in the fuel tank is less than the E (or Empty) gauge needle stop position for five consecutive
seconds, the gauge needle is moved to the low end of the gauge scale and the low fuel indicator is
illuminated immediately. This input would indicate that the fuel level sense input to the TIPM is a short
