Mechanical Instrument Cluster (Mic)

With several different Mechanical Instrument Cluster (MIC) packages available, typical high-line model MICs include, but are not limited to, a speedometer, tachometer, fuel gauge, oil pressure gauge, water temperature gauge, voltmeter, an information Vacuum Fluorescent Display (VFD) and a series of warning lights (if equipped).

Powertrain Control Module (PCM) sends signals necessary for MIC to position gauges. MIC receives continuously updated messages through CCD bus and translates them to gauge positions. Central Timer Module (CTM) sends necessary signals for all indicator lights and dimming level settings to MIC through CCD bus, when ignition switch is in ON or START positions. Malfunction (CHECK ENGINE) indicator light state is sent to CTM from PCM through CCD bus. VFD odometer/trip display works when ignition switch is in ON or START positions from CTM, which also stores actual mileage information that odometer displays. If CCD bus network is transmitting data, odometer will display dashes (- -) instead of mileage reading. All other MIC features only work when ignition switch is in ON position.
