Instrument Cluster

Instrument cluster includes a speedometer, tachometer, fuel gauge, oil pressure gauge, water temperature gauge, voltmeter and a series of warning lights.

Powertrain Control Module (PCM) sends signals necessary for the cluster to position gauges. Cluster receives these messages from CCD bus and translates them into gauge positions. BCM sends status of all indicator lights and dimming level to instrument cluster over CCD bus when ignition switch is in RUN or START positions. Malfunction (CHECK ENGINE) indicator light status is sent to BCM from PCM over CCD bus. Vacuum fluorescent odometer/trip display works when ignition switch is in RUN or START positions. BCM stores mileage information that odometer displays. If CCD bus is not functioning, odometer will display dashes instead of the mileage numbers. BCM sends mileage message and dimming level message to vacuum fluorescent display when ignition switch is in the ON position. All other instrument cluster features only work when the ignition switch is in the RUN position.
