    • Is the voltage greater than 10 volts? 

    Yes:  GO to  AG3.

    No:  REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.

  3. AG3 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION 
    • Disconnect all instrument cluster connectors.
    • Check for:
      • corrosion
      • pushed-out pins
    • Connect all instrument cluster connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 

    Yes:  INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER . TEST the system for normal operation.

    No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
