Instrument Cluster

INSTRUMENT CLUSTER
The Instrument Cluster receives and sends messages to other modules via the PCI bus circuit. The indicator lamps will illuminate briefly for a bulb check when the ignition is turned from off to run. All of the gauges receive their information via the PCI bus from the powertrain control module and body control module.

The gauges and the LEDs are not individually replaceable thereby requiring complete replacement of the Instrument Cluster if a repair is necessary. In the event that the Instrument Cluster loses communication with other modules on the PCI bus, the cluster will display "no bus" in the VF display.

The Trip/Reset button is used to switch the display from trip to total mileage. Holding the button when the display is in the trip mode will reset the trip mileage. This button is also used to put the cluster into self-diagnostic mode. The odometer display uses blue-green vacuum fluorescent digital characters.

On base models, the Instrument Cluster has three gauges: Speedometer, fuel and temperature. A red dot appears through openings in the Instrument Cluster face (P-R-N-D-2-1) to indicate the gear selected.

With other models, the Instrument Cluster may also include a tachometer and use a vacuum-fluorescent shift indicator.

The high-line Instrument Cluster features Electroluminescent Illumination of the gauge faces (EL Panel). This feature eliminates the use of bulbs for gauge/panel lighting. In a manner similar to fluorescent lights, a/c voltage from an inverter integrated circuit chip is applied to the phosphorescent material, causing it to glow. The phosphorescent material is screen-printed onto flexible Mylar sheets that form the gauge faces.

The odometer display and door/liftgate ajar indicators turn on when a door is opened to assist both the customer and service technician to view the odometer without turning the ignition on.

On models with AutoStick, the display includes an O/D OFF indicator that is illuminated when the driver presses the Overdrive Off button on the transaxle shifter.

For complete details of the Instrument Cluster, refer to the RS/RG.

INSTRUMENT CLUSTER SELF TEST
1. Depress and hold the Odometer Reset button.
2. Turn the ignition switch to on.
3. Release the Odometer reset button.

The Instrument Cluster will illuminate all indicators and step the gauges through several calibration points. Also, the odometer will display any stored codes that may have set.

MESSAGE CENTER (EXPORT ONLY)
The Message Center is above the brow of the Instrument Cluster. It houses the following warning indicators: Water & Fuel, High Beam, Left and Right turn signals, Glow Plug, and Supplemental Heat. On base models equipped with the three-speed transaxle, these indicators appear in the face of the cluster. The Security Alarm set indicator is now a large red circle symbol.
