Instrument Panel Electronic Pack ( John Ping,
October 20, 2001
The Instrument Panel "Electronic Pack" is mounted to the rear of the panel. As mentioned before, it is a crème colored rectangular shaped plastic module with dimensions of approximately 15" length x 5" width x 2" height. Inspect the two multi-pin female type connectors located on the rear of the pack to ensure / rectify any visible defects such as deformed pins or corrosion. Always use a quality electronics parts cleaner to removed films or dust/dirt from these connectors. No petroleum-based products should be utilized! With the Instrument Panel inverted to allow access to the "microprocessor electronic pack", remove the ten (10) No. 1 Phillips self-tapping screws which are located around the perimeter and connector portion of the module.
With the cover plate removed from the module, the microprocessor board is visible. There are no "owner" repairable items on this board. The microprocessor provides output to the gauges / displays via the use of three "printed circuit board type" ribbon strips. Release each ribbon strip by pulling up on the strip locks on each end of the ribbon. With the locks released, the strip can simply be pulled upward to release. This step should be performed to the other two strips.
The electronics pack can now be disconnected from the Instrument Panel by releasing the two plastic clips at the bottom and pivoting upward on the module to approximately a 90-degree position such the hinges on top will release. Note that the hinges on the module are split to allow separation from the Instrument Panel.
Note: The electronic pack has a specific "speedometer calibration". If replacing this item, ensure the replacement electronic pack is marked with the exact "speedometer calibration" as the original electronic pack or the speedometer indication will be incorrect. The odometer reading is stored within the electronic pack. When installing a replacement pack, the odometer will not readout with the original vehicle mileage.
As with the Instrument Panel, installation is truly the reverse of removal. Ensure the three printed circuit ribbon strips are securely installed on their connectors and the locking devices are in proper position prior to re-installing the rear cover plate.this case, re-installation is honestly the reverse of removal. Just ensure the Instrument Panel is properly re-fit in the dash prior to installing fasteners. The Instrument Panel dash pad has locator tabs at the front corners, which mate with slots on the lower dash frame. Significant effort is not required to re-install the Instrument Panel into the dash.
