Pinpoint Test A: The IPC Is Inoperative

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. 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 CHECK THE IPC HOT AT ALL TIMES VOLTAGE SUPPLY 
    • Ignition OFF.
    • Disconnect: IPC C220.
    • Measure the voltage between the IPC C220-6, circuit SBP11 (BU/RD or YE/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to A2.
    • No  : VERIFY the BCM fuse 11 (10A) is OK. If OK, REPAIR circuit SBP11 (BU/RD or YE/RD) for an open. If not OK, REFER to the appropriate SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. TEST the system for normal operation.
  2. A2 CHECK THE IPC GROUND CIRCUIT FOR AN OPEN 
    • Measure the voltage between the IPC C220-6, circuit SBP11 (BU/RD or YE/RD), harness side and the IPC C220-22, circuit GD184 (BK/GY or BK/YE), harness side.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to A3.
    • No  : REPAIR circuit GD184 (BK/GY or BK/YE) for an open. TEST the system for normal operation.
  3. A3 VERIFY THE IPC PASSES THE NETWORK TEST 
    • Connect: IPC C220.
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Network Test.
    • In the LH pane of the Integrated Diagnostic System (IDS) network test display screen, verify whether the IPC passed the network test.
    • Did the IPC pass the network test? 
  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) . 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.
