Pinpoint Test A: No Communication With The Instrument Cluster

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.
  1. A1 CHECK THE INSTRUMENT CLUSTER VOLTAGE SUPPLY 
    • Key in OFF position.
    • Disconnect: Instrument Cluster C2220.
    • Key in ON position.
    • Measure the voltage between the instrument cluster, harness side and ground as follows:
      INSTRUMENT CLUSTER CONNECTOR AND CIRCUIT

      Instrument Cluster Connector-Pin Circuit
      C2220-1 54 (LG/YE)
      C2220-17 1003 (GY/YE)
      C2220-19 640 (RD/YE)
    • Are the voltages greater than 10 volts? 

    Yes  : GO to A2.

    No  : VERIFY the CJB fuses 1 (15A), 6 (10A) and 26 (10A) are OK. If OK, REPAIR the circuit. TEST the system for normal operation.

  2. A2 CHECK THE INSTRUMENT CLUSTER GROUND CIRCUITS 
    • Key in OFF position.
    • Measure the resistance between the instrument cluster, harness side and ground as follows:
      INSTRUMENT CLUSTER CONNECTORS AND CIRCUITS

      Instrument Cluster Connector-Pin Circuit
      C2220-2 676 (PK/OG)
      C2220-18 57 (BK)
    • Are the resistances less than 5 ohms? 

    Yes  : REFER to MODULE COMMUNICATIONS NETWORK to continue diagnosis of the communication network.

    No  : REPAIR the circuit. TEST the system for normal operation.
