Mechanical Instrument Cluster

Body control module sends the angular position of 4 gauges, the status of 7 indicator lights, the status and dimming of PRNDL indicator, the dimming of cruise and low fuel warning lights, and odometer stepper motor information to the mechanical instrument cluster over the CCD bus when the ignition switch is in OFF (unlock), RUN and START positions.

All mechanical instrument cluster features operate when ignition switch is in the RUN position. The PRNDL feature operates when ignition switch is in the OFF, RUN or START position.

On the transition from OFF to RUN position, a bulb check is performed. This bulb check consists of activating all CCD controlled indicator lights and all PRNDL segments for approximately 2-4 seconds. PRNDL bulb check is aborted if gear selector is moved out of Park position and if tachometer exceeds 450 RPM.
