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

WARNING: This page is about a different car, the 2011 Lincoln MKT. 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. N1 CHECK THE FCIM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: FCIM C2403.
    • Ignition ON.
    • Measure the voltage between the FCIM C2403-5, circuit SBP15 (WH/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
    1. Yes  : GO to N2.
    2. No  : VERIFY the Smart Junction Box (SJB) fuse 15 (10A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the network test with the scan tool.
  2. N2 CHECK THE FCIM GROUND CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Measure the resistance between the FCIM C2403-8, circuit GD114 (BK/BU), harness side and ground.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to N3.
    2. No  : REPAIR the circuit. CLEAR the DTCs. REPEAT the network test with the scan tool.
  3. N3 CHECK THE MS-CAN CIRCUITS BETWEEN THE FCIM AND THE DLC FOR AN OPEN 
    • Measure the resistance between the FCIM C2403-1, circuit VDB06 (GY/OG), harness side and the DLC C251-3, circuit VDB06 (GY/OG), harness side.

    • Are the resistances less than 5 ohms? 
    1. Yes  : GO to N4.
    2. No  : REPAIR the circuit in question. CLEAR the DTCs. REPEAT the network test with the scan tool.
  4. N4 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? 
    1. Yes  : INSTALL a new FCIM. REFER to INFORMATION SYSTEM AND ENTERTAINMENT SYSTEM article. CLEAR the DTCs. REPEAT the network test with the scan tool.
    2. No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
