Pinpoint Test L: The Front Controls Interface Module (FCIM) Does Not Respond To The Diagnostic Scan Tool

WARNING: This page is about a different variant/trim than selected.
  1. L1 CHECK THE MS-CAN (MEDIUM SPEED-CONTROLLER AREA NETWORK) TERMINATION RESISTANCE 
    • Ignition OFF.
    • Disconnect negative battery cable.
    • Disconnect the diagnostic scan tool cable from the DLC.
    • Disconnect: GWM C2431  .
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C2431-23  OHM C2431-22 

    Is the resistance between 108 and 132 ohms? 

    1. Yes  : GO to  L3
    2. No  : GO to L2 
  2. L2 CHECK THE MS-CAN (MEDIUM SPEED-CONTROLLER AREA NETWORK) CIRCUITS BETWEEN THE FCIM (FRONT CONTROLS INTERFACE MODULE) AND THE GWM (GATEWAY MODULE A) FOR AN OPEN 
    • Disconnect FCIM C2402A  .
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C2402A-17  OHM C2431-23 
      C2402A-18  OHM C2431-22 

    Are the resistances less than 3 ohms? 

    1. Yes  : GO to  L5
    2. No  : REPAIR the circuit in question.
  3. L3 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) VOLTAGE SUPPLY CIRCUIT FOR AN OPEN 
    • Connect negative battery cable.
    • Ignition ON.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C2402A-26  VOLTAGE Ground

    Is the voltage greater than 11 volts? 

    1. Yes  : GO to L4 
    2. No  : VERIFY the BCM fuse 12 (7.5A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM WIRING DIAGRAMS -- (EXCEPT HYBRID) to identify the possible causes of the circuit short.
  4. L4 CHECK THE FCIM (FRONT CONTROLS INTERFACE MODULE) GROUND CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect negative battery cable.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C2402A-1  OHM Ground

    Is the resistance less than 3 ohms? 

    1. Yes  : CONNECT negative battery cable. GO to L5 
    2. No  : REPAIR the circuit.
  5. L5 CHECK FOR CORRECT FCIM (FRONT CONTROLS INTERFACE MODULE) OPERATION 
    • Ignition OFF.
    • Disconnect and inspect all the FCIM connectors.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the FCIM connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    1. Yes  : CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new FCIM. Refer to the appropriate Information and Entertainment System article for the procedure.
    2. No  : The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
