Preliminary Diagnosis

  1. If indicator lights operate, but all gauges are inoperative, go to next step. If all gauges and indicator lights are inoperative, go to step 5).
  2. Remove and inspect fuse No. 16 (15-amp) in Power Distribution Center (PDC). PDC is located in engine compartment, near battery. If fuse is okay, go to next step. If fuse is blown, locate and repair cause of blown fuse. Install new fuse and recheck system operation.
  3. Measure voltage between ground and power side of fuse No. 16 fuse holder. If battery voltage is present, go to next step. If battery voltage is not present, locate and repair open circuit.
  4. Remove instrument cluster. See REMOVAL & INSTALLATION  . Reconnect negative battery cable. Measure voltage between ground and terminal No. 9 (Pink wire) at instrument cluster 10-pin Black connector. If battery voltage is present, reinstall instrument cluster and go to ACTUATOR TEST  . If battery voltage is not present, repair open circuit between fuse No. 16 in PDC and instrument cluster 10-pin Black connector.
  5. Remove and inspect fuse No. 9 (10-amp) in junction block. Junction block is located behind right side kick panel. If fuse is okay, go to next step. If fuse is blown, locate and repair cause of blown fuse. Install new fuse and recheck system operation.
  6. Turn ignition on. Measure voltage between ground and power side of fuse No. 9 fuse holder. If battery voltage is present, go to next step. If battery voltage is not present, locate and repair open circuit between ignition switch and junction block.
  7. Turn ignition on. Set parking brake and observe instrument cluster brake warning light. If brake warning light is on, go to next step. If brake warning light is off, go to step 9).
  8. Turn parking lights on and adjust instrument panel lights dimmer rheostat to full bright position. If instrument panel lights are on, go to ACTUATOR TEST  . If instrument panel lights are off, go to step 10).
  9. Remove instrument cluster. See REMOVAL & INSTALLATION  . Reconnect negative batter cable. Turn ignition on. Measure voltage between ground and terminal No. 8 (White/Black wire) at instrument cluster 10-pin Black connector. If battery voltage is present, go to ACTUATOR TEST  . If battery voltage is not present, locate and repair open circuit.
  10. Remove instrument cluster. See REMOVAL & INSTALLATION  . Using an ohmmeter, check for continuity between ground and terminal No. 1 (Black/Light Green wire) at instrument cluster 10-pin Black connector. If continuity exists, go to ACTUATOR TEST  . If continuity does not exist, locate and repair open in ground circuit.
