Electronic Instrument Cluster
The electronic instrument cluster is made up of two assemblies. These assemblies are:- electronic instrument cluster.
- message center control and message center switch module assembly.
The electronic instrument cluster:
- consists of one microcomputer-based module
- processes sensor information
- controls three vacuum fluorescent displays for:
- speedometer/odometer
- fuel gauge and engine coolant temperature gauge
- message center
These warning indicators are located in the indicator lamp module:
- traction control
- anti-lock brake
- brake
- hazard
All other warning indicators are included in the electronic instrument cluster.
LH display warnings:
- AIR BAG*
- Charging System*
- CHECK ENGINE*
- Safety Belt*
- Oil Pressure*
- Fail Safe Cooling
- LOW FUEL
Center display warnings:
- SPEED CONTROL
- High Beams*
- Left Turn Signal*
- Right Turn Signal*
RH display warnings:
- CHECK AIR SUSPENSION
- OVERDRIVE OFF
- DOOR AJAR
- TRUNK AJAR
- LOW WASHER FLUID
* These warning indicators cannot be dimmed.
The electronic instrument cluster is operational only when the ignition switch is in RUN. The electronic vacuum fluorescent displays are powered by a nonserviceable internal power supply. The only illumination bulb used, which is not serviceable, is for backlighting of the transmission range indicator. When the headlamps are turned on, the instrument cluster dims according to the interior lighting control paddle position (except those warnings indicated above, which do not dim).
