7 CHECK CIRCUIT (LG) FOR A SHORT TO GROUND
  • Key OFF.
  • Disconnect: Instrument cluster 0922-102
  • Measure the resistance between the instrument cluster 0922-102 pin 9, circuit (LG), harness side and ground.
  • Is the resistance greater than 10,000 ohms? 
 Yes Go to next step.
No Repair circuit (LG) for a short to ground. Test the system for normal operation.
8 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
  • Disconnect all the instrument cluster connectors.
  • Check for:
    • Corrosion
    • pushed-out pins
  • Connect all the instrument cluster connectors and make sure they seat correctly.
  • Operate the system and verify the concern is still present.
  • Is the concern still present?
