Instrument Cluster Inoperative

  1. Turn ignition switch to OFF position. Disconnect instrument cluster Green 32-pin connector C1. See Figure . Turn ignition switch to RUN position. Using DVOM, check voltage between instrument cluster harness connector C1, terminal D9 (Pink wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in circuit No. 439 (Pink wire) between instrument cluster connector C1 and instrument panel junction block. Recheck system operation.
  2. Turn ignition switch to OFF position. Disconnect instrument cluster Orange 32-pin connector C2. See Figure . Turn ignition switch to RUN position. Check voltage between instrument cluster harness connector C2, terminal F16 (Pink wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in circuit No. 439 (Pink wire) between instrument cluster connector C2 and instrument panel junction block. Recheck system operation.
  3. Check voltage between instrument cluster harness connector C2, terminals F16 (Pink wire) and F7 (Black/White wire). Check voltage between instrument cluster harness connector C2, terminals F16 (Pink wire) and F8 (Black/White wire). If battery voltage exists at both terminals, go to next step. If battery voltage does not exist at both terminals, repair open in appropriate circuit No. 451 (Black/White wire) between instrument cluster connector C2 and ground. Recheck system operation.
  4. Check voltage between instrument cluster harness connector C2, terminals F16 (Pink wire) and E11 (Black wire). Check voltage between instrument cluster harness connector C2, terminals F16 (Pink wire) and E12 (Black wire). If battery voltage exists at both terminals, go to next step. If battery voltage does not exist at both terminals, repair open in appropriate circuit No. 1250 (Black wire) between instrument cluster connector C2 and ground. Recheck system operation.
  5. Check voltage between instrument cluster harness connector C2, terminal F5 (Pink wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in circuit No. 439 (Pink wire) between instrument cluster connector C2 and instrument panel junction block. Recheck system operation.
  6. Check voltage between instrument cluster harness connector C2, terminal F4 (Light Green wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in circuit No. 147 (Light Green wire) between instrument cluster connector C2 and instrument panel fuse block. Recheck system operation.
  7. Turn ignition switch to OFF position. Using DVOM, check voltage between instrument cluster harness connector C2, terminal F3 (Orange wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in circuit No. 40 (Orange wire) between instrument cluster connector C2 and instrument panel fuse block. Recheck system operation.
  8. Check for poor terminal contact at instrument cluster connector C1, terminal D9 (Pink wire). Check for poor terminal contact at instrument cluster connector C2, terminals F16 (Pink wire), F5 (Pink wire), F4 (Light Green wire), F3 (Orange wire), F7 (Black/White wire), F8 (Black/White wire), E11 (Black wire) and E12 (Black wire). Repair as necessary and recheck system operation. If contacts are okay, replace instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Recheck system operation.
