Test 56A - All Gauges Inoperative

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  . For wiring diagrams, see appropriate article in ENGINE PERFORMANCE:
  1. Turn ignition off. Remove and inspect fuse No. 17. See Figure . If fuse is open, go to TEST 56B  . If fuse is okay, reinstall fuse. Go to next step.
  2. Turn ignition on. Using scan tool in voltmeter mode, check voltage on fuse No. 17 (Red/White wire). If voltage is less than 10 volts, go to step 7). If voltage is more than 10 volts, go to next step.
  3. Turn ignition off. Disconnect instrument cluster Black connector. Turn ignition on. Check voltage on instrument cluster Black connector terminal No. 6 (Red/White wire). If voltage is less than 10 volts, repair open Red/White wire. If voltage is more than 10 volts, go to next step.
  4. Connect a jumper wire between instrument cluster Black connector terminal No. 3 (Violet/Brown wire) and chassis ground. Using scan tool, perform CCD bus test. If scan tool does not display BUS SHORTED TO GROUND, repair open Violet/Brown wire between Body Control Module (BCM) and instrument cluster. If scan tool displays BUS SHORTED TO GROUND, go to next step.
  5. Connect a jumper wire between instrument cluster Black connector terminal No. 2 (White/Black wire) and chassis ground. Using scan tool, perform CCD bus test. If scan tool does not display BUS SHORTED TO GROUND, repair open White/Black wire between BCM and instrument cluster. If scan tool displays BUS SHORTED TO GROUND, go to next step.
  6. Close all doors. Turn ignition off. Using scan tool in ohmmeter mode, check resistance of instrument cluster Black connector terminal No. 1 (Black/Light Green wire). If resistance is more than 100 ohms, repair open Black/Light Green wire. If resistance is less than 100 ohms, replace instrument cluster.
  7. Turn ignition off. Disconnect ignition switch connector. See Figure . Turn ignition on. Using scan tool in voltmeter mode, check voltage on ignition switch connector terminal No. 9 (Red wire). If voltage is less than 10 volts, repair open Red wire. If voltage is more than 10 volts, go to next step.
  8. Turn ignition off. Using an external ohmmeter, check resistance of Red/White wire between ignition switch connector terminal No. 8 and fuse No. 17. If resistance is more than 5 ohms, repair open Red/White wire. If resistance is less than 5 ohms, replace ignition switch.
