Mechanical Instrument Cluster (MIC)

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 the 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.
