Instrument Panel, Gauges and Warning Indicators: Description and Operation

MECHANICAL INSTRUMENT CLUSTER (MIC)

Information Center:

Description
The instrumentation gauges on NS vehicles are contained in a subdial assemblies within the instrument cluster. The individual gauges are not serviced separately. If one of the cluster gauges becomes faulty the entire subdial would require replacement and all gauges will have to be calibrated. Refer to the proper Body Diagnostic Procedure for calibration procedures.

The mechanical instrument cluster with a tachometer is equipped with a electronic vacuum fluorescent transmission range indicator (PRND3L), odometer, and trip odometer display.

The mechanical instrument cluster without a tachometer is equipped with a cable operated transmission range indicator (PRND21).

The instrument cluster is equipped with the following warning lamps.
- Liftgate Ajar
- Low Fuel Level
- Low Windshield Washer Fluid Level
- Cruise
- Battery Voltage
- Fasten Seat Belt
- Door Ajar

Operation
The Body Control Module sends the angular position of the gauges, the status of all CCD indicator lamps, the status and dimming of the mechanical instrument cluster (MIC) over the CCD bus when the ignition is in the "OFF" (unlock), "RUN", or "START" positions. The PRNDL (VF, if equipped) and odometer/trip displays work when the ignition is in the "OFF" (unlock), "RUN", or "START" positions. All other MIC features work only when ignition is in the "RUN" position. On transition of the ignition from the "OFF" to the "RUN" position, a bulb check is performed. This consists of activating all CCD controlled indicator lamps and all VF display segments for approximately 2 - 4 seconds. The PRNDL bulb check is aborted if the gear selector is moved from the PARK position, or if the engine exceeds 450 rpm.

Refer to the vehicle Owner's Manual for operating instructions and conditions for the Instrument Cluster gauges.
