Pinpoint Test J: The FCIM Does Not Respond To The Scan Tool

WARNING: This page is about a different car, the 2013 Ford Mustang. 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.
NOTE: Failure to disconnect the battery when instructed results in false resistance readings. Refer to BATTERY, MOUNTING AND CABLES .
  1. J1 CHECK THE FCIM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: FCIM C2402.
    • Ignition ON.
    • Measure the voltage between the FCIM C2402-1, circuit SBP14 (BN/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to J2.
    • No  : VERIFY the Smart Junction Box (SJB) fuse 14 (10A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the network test with the scan tool.
  2. J2 CHECK THE FCIM GROUND CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: Negative Battery Cable.
    • Measure the resistance between the FCIM C2402-4, circuit GD115 (BK/GY), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to J3.
    • No  : REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
  3. J3 CHECK THE MS-CAN CIRCUITS BETWEEN THE FCIM AND THE DLC FOR AN OPEN 
    • Measure the resistance between the FCIM C2402-2, circuit VDB06 (GY/OG), harness side and the Data Link Connector (DLC) C251-3, circuit VDB06 (GY/OG), harness side.

    • Are the resistances less than 5 ohms? 
    • Yes  : CONNECT the negative battery cable. GO to J4.
    • No  : REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
  4. J4 CHECK FOR CORRECT FCIM OPERATION 
    • Disconnect the FCIM connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the FCIM connector and make sure it seats correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes  : INSTALL a new FCIM. REFER to INFORMATION AND ENTERTAINMENT SYSTEMS . CLEAR the DTCs. REPEAT the network test with the scan tool.
    • No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the network test with the scan tool.
