Pinpoint Test Ad: DTC U3003:16 (FCIM)

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. 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 .
  1. AD1 RECHECK THE FCIM DTCs 
    • Ignition ON.
    • Clear the FCIM  DTCs.
    • Wait at least 15 seconds.
    • Repeat the FCIM  self-test.
    • Is DTC U3003:16 still present? 
    • Yes:  GO to AD2  .
    • No:  The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
  2. AD2 CHECK FOR CHARGING SYSTEM DTCs IN THE PCM 
    • Retrieve the continuous DTCs from all modules.
    • Is DTC P0620, P0622, P0625 or P065B set in the PCM? 
  3. AD3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE 
    • Check the battery condition and verify that the battery is fully charged. Refer to BATTERY, MOUNTING AND CABLES .
    • Is the battery OK and fully charged? 
  4. AD4 CHECK THE FCIM VOLTAGE SUPPLY 
    • Ignition OFF.
    • Measure and record the voltage at the battery.
    • Disconnect: FCIM  C2402.
    • Ignition ON.
    • Measure the voltage between the FCIM  C2402-1, circuit SBP14 (BN/RD), harness side and ground.

    • Is the voltage at the FCIM within 0.2 volt of the recorded battery voltage? 
    • Yes:  GO to AD5  .
    • No:  REPAIR the circuit for high resistance. CLEAR the DTCs. REPEAT the self-test.
  5. AD5 CHECK THE FCIM GROUND CIRCUIT 
    • Ignition OFF.
    • Disconnect: Negative Battery Cable.
    • Measure the resistance between the FCIM  C2402-2, circuit GD115 (BK/GY), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes:  GO to AD6  .
    • No:  REPAIR the circuit for high resistance. CLEAR the DTCs. REPEAT the self-test.
  6. AD6 CHECK FOR CORRECT FCIM OPERATION 
    • Ignition OFF.
    • Connect: Negative Battery Cable.
    • 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 determine if the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new FCIM  . REFER to FRONT CONTROLS INTERFACE MODULE (FCIM) . 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.
