Pinpoint Test A: The Instrument Cluster (Ic) Is Inoperative

WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. A1 RETRIEVE THE RECORDED DTCs FROM THE CONTINUOUS INSTRUMENT CLUSTER (IC) SELF-TEST 
    • Check for recorded instrument cluster (IC) DTCs from the continuous self-test.
    • Is DTC U2472 recorded? 
    1. YES  : Go to Pinpoint Test AC .
    2. NO  : Go to  A2.
  2. A2 CHECK THE INSTRUMENT CLUSTER (IC) B+ VOLTAGE SUPPLY 
    • Key in OFF position.
    • Disconnect: Instrument Cluster (IC) C220
    • Measure the voltage between the instrument cluster (IC) C220-1, circuit SBP26 (YE/RD), harness side and ground.
    • Fig 1: Measuring Voltage

    • Are the voltages greater than 10 volts? 
    1. YES  : Go to  A3.
    2. NO  : VERIFY SJB fuse 26 (10A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
  3. A3 CHECK THE INSTRUMENT CLUSTER (IC) RUN/START VOLTAGE SUPPLY 
    • Key in ON position.
    • Measure the voltage between the instrument cluster (IC) C220-14, circuit CBP29 (WH/VT), harness side and ground.
    • Fig 2: Measuring Voltage

    • Are the voltages greater than 10 volts? 
    1. YES  : Go to  A4.
    2. NO  : VERIFY SJB fuse 29 (5A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
  4. A4 CHECK THE INSTRUMENT GROUND CIRCUIT GD111 (BK/BU) FOR AN OPEN 
    • Key in OFF position.
    • Measure the resistance between the instrument cluster (IC) C220-6, circuit GD111 (BK/BU), harness side and ground; and between the instrument cluster (IC) C220-20, circuit GD111 (BK/BU), harness side and ground.
    • Fig 3: Measuring Resistance

    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  A5.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  5. A5 CHECK FOR CORRECT INSTRUMENT CLUSTER (IC) OPERATION 
    • Disconnect the instrument cluster (IC) connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the instrument cluster (IC) connector and make sure it seats correctly.
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
    1. YES  : INSTALL a new instrument cluster (IC). REFER to Instrument Cluster (IC) . TEST the system for normal operation.
    2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
