Electronic Instrument Cluster

Inspection and Verification

1. Visually inspect the components. Check for damaged components, blown fuses, and loose or corroded connections. Check the wiring harness for obvious signs of shorts, opens, bad connections or damage.

2. Verify speedometer and odometer operation by road testing the vehicle.

3. Perform Electronic Instrument Cluster Self Test, prior to performing any Pinpoint Tests.

Electronic Cluster, Diagnostic Test Mode:

a. Press the E/M and (<)SELECT buttons simultaneously while turning ignition switch from OFF to RUN. The electronic instrument cluster will enter a special test mode and display information in the center display opening. Information displayed includes a number in the speedometer display and two numbers in the odometer display, one on the left and one on the right. Both the left and right display openings will be dark (off).

Electronic Cluster, Function Diagnostic Mode:

b. If any of the displayed information in the center opening flashes on and oft continuously, the electronic instrument cluster is inoperative and should be replaced. (After replacing the instrument cluster (10849), verify that the symptom is no longer present. If symptoms persist, begin diagnosis again.) If the display does not flash, turn the ignition switch to OFF to exit this special test mode. Then continue through the diagnosis section (the instrument cluster may or may not be damaged at this point).
