Self-Diagnostic Test

  1. Remove lower left bezel retaining screws and remove bezel. Push red button on cluster located to right of steering wheel.
  2. Cluster will simultaneously activate one common segment in each character for two seconds. The lighted segments will be changed in the characters in a logical fashion. A visual inspection is required to locate shorted or inoperative segments.
  3. Cluster will now proceed to conduct internal checks of the microcomputer system. If there is any detected faults, the odometer will display a "FAIL 2" or "FAIL 3", and the self-test will stop. If no failures are located, "PASS 1", "PASS 2" or "PASS 3" will be indicated on the odometer.
  4. If there are no failures detected, all displays will be turned on to indicate inoperative segments. The cluster will remain in this state until the ignition is turned "ON".
