Pinpoint Test A: The IPC Is Inoperative

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Failure to use the correct probe adapter(s) may damage the connector.
  1. A1 RETRIEVE THE RECORDED DTCs FROM THE CONTINUOUS IPC SELF-TEST 
    • Check for recorded IPC  DTCs from the continuous self-test.
    • Is DTC U300A:62 recorded? 
    • Yes  : VERIFY SJB fuse 29 (5A) is OK. If OK, GO to PINPOINT TEST BZ . If not OK, REFER to the SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short.
    • No  : GO to A2.
  2. A2 CHECK THE IPC VOLTAGE SUPPLY 
    • Ignition OFF.
    • Disconnect: IPC  C220.
    • For the non-hybrid, measure the voltage between the IPC  C220-21, circuit SBP26 (YE/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to A3.
    • No  : VERIFY SJB fuse 26 (10A) is OK. If OK, REPAIR the circuit for an open. If not OK, REFER to the SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. TEST the system for normal operation.
  3. A3 CHECK THE IPC GROUND CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • For the non-hybrid, measure the voltage between the IPC  C220-21, circuit SBP26 (YE/RD), harness side and the IPC  C220-5, circuit GD116 (BK/VT), harness side.

    • For the hybrid, measure the voltage between the IPC  C220-19, circuit SBP26 (YE/RD), harness side and the IPC  C220-9, circuit GD116 (BK/VT), harness side.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to A4.
    • No  : REPAIR circuit GD116 (BK/VT) for an open. TEST the system for normal operation.
  4. A4 CHECK FOR CORRECT IPC OPERATION 
    • Disconnect the IPC  connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the IPC  connector and make sure it seats correctly.
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
    • Yes  : INSTALL a new IPC  . REFER to INSTRUMENT PANEL CLUSTER (IPC)  in this service information. 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.
