PINPOINT TEST J : The FCIM Does Not Respond To The Diagnostic Scan Tool

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. REFER to Battery, Mounting and Cables .

    Is the voltage greater than 11 volts? 

    Yes  GO to  J2.
    No  VERIFY the BCM fuse 9 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM Electrical Wiring Diagram Introduction to identify the possible causes of the circuit short.

    Is the resistance less than 3 ohms? 

    Yes  GO to  J3.
    No  REPAIR the circuit.
  3. J3 CHECK THE I-CAN CIRCUITS BETWEEN THE FCIM AND THE IPC FOR AN OPEN

    • Disconnect: IPC C220 .

    Are the resistances less than 3 ohms? 

    Yes  CONNECT the negative battery cable. GO to  J4.
    No  REPAIR the circuit in question.
  4. J4 CHECK FOR CORRECT FCIM OPERATION

    • Ignition OFF.
    • Disconnect and inspect the FCIM connector and related in-line connectors.
    • Repair:
      • corrosion (replace connector or terminals - clean module pins)
      • damaged or bent pins - replace terminals/pins
      • pushed-out pins - replace pins as necessary
    • Reconnect the FCIM connector and related in-line connectors. Make sure they seat and latch correctly.
    • Operate the system and verify the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs address this concern, INSTALL a new FCIM. Refer to the appropriate Information and Entertainment Systems article for the procedure.
    No  The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
