Pinpoint Test T: U3006:1C

WARNING: This page is about a different car, the 2023 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to POWER DISTRIBUTION/BCM for schematic and connector information. Refer to OEM GROUND DISTRIBUTION for schematic and connector information.

    Normal Operation and Fault Conditions 

    The BCM receives voltage at all times from the BJB.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    BCM U3006:1C Control Module Input Power 'A' Circuit/Open: Circuit Voltage Out Of Range A continuous memory DTC that sets in the BCM if the BCM detects out of range voltage on the voltage supply input circuits.

    Possible Sources 

    • Wiring, terminals or connectors
    • Charging system concern
    • Battery concern
    • BJB
    • BCM

  2. T1 CHECK THE BCM (BODY CONTROL MODULE) FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, perform the BCM self-test.

    Are there any charging system DTCs present? 

    Yes  REFER to Diagnostic Trouble Code (DTC) Chart 
    No  GO to  T2

  3. T2 CHECK FOR CHARGING SYSTEM DTCS SET IN OTHER MODULES

    • Ignition ON.

    • Using a diagnostic scan tool, retrieve all DTCs.

    Are there any charging system DTCs present in other modules? 

    Yes  REFER to Diagnostic Trouble Code (DTC) Chart 
    No  GO to  T3

  4. T3 CHECK THE BATTERY VOLTAGE

    • Turn off all interior/exterior lights and accessories.

    • Start and run the engine at approximately 2, 000 rpm for three minutes while monitoring the battery voltage.

    Does the battery voltage rise to 16 volts or higher? 

    Yes  Diagnose the over-charging system concern. REFER to: Charging System - 1.5L EcoBoost (132kW/180PS) - I3 (Y1) . REFER to: Charging System - 2.0L EcoBoost (177kW/240PS) - MI4 .
    No  GO to  T4

  5. T4 RECHECK THE BCM (BODY CONTROL MODULE) DTCS

    • Ignition OFF.

    • Ignition ON.

    • Using a diagnostic scan tool, clear the DTCs.

    • Wait 10 seconds.

    • Using a diagnostic scan tool, check the BCM DTCs.

    Is DTC U3006:1C present? 

    Yes  GO to  T5
    No  The system is operating correctly at this time. The DTC may have been caused by module connections or may have been set previously during battery charging or while jump starting the vehicle. ADDRESS the root cause of any connector or pin issues.

  6. T5 CHECK THE BATTERY CONDITION AND STATE OF CHARGE

    • Check the battery condition and verify the battery is fully charged. REFER to: Battery .

    Is the battery OK and fully charged? 

    Yes  GO to  T6
    No  If the battery is discharged, diagnose the cause of the low battery condition. REFER to: Battery . If the battery condition fails, INSTALL a new battery. REFER to: Battery .

  7. T6 COMPARE THE BCM (BODY CONTROL MODULE) BATTERY VOLTAGE PID (PARAMETER IDENTIFICATION) WITH ACTUAL BATTERY VOLTAGE

    • Start the engine.

    • Turn on accessories (climate control blower on high speed, exterior lights).

    • Access the BCM and monitor the VPWR_RAW (V) PID

      Compare BCMPID with actual battery voltage.

    • With the engine running at idle, measure and record battery voltage:

    • Using a diagnostic scan tool,

      Access the BCM and monitor the VPWR_RAW (V) PID

    Is the recorded battery voltage within 0.2 volt of the 

    Access the BCM and monitor the VPWR_RAW (V) PID 

    ? 

    Yes  TURN the engine off, GO to  T9
    No  GO to  T7

  8. T7 CHECK THE BCM (BODY CONTROL MODULE) VOLTAGE SUPPLY CIRCUIT

    • Ignition OFF.

    • Ignition ON.

    • Measure:

      		 Ground
      Positive Lead Measurement / Action Negative Lead
      C2280B Pin 1
      GFD747052Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the voltage within 0.2 volt of the recorded battery voltage? 

    Yes  GO to  T8
    No  REPAIR the faulty circuit.

  9. T8 CHECK THE BCM (BODY CONTROL MODULE) PROCESSOR GROUNDS

    • Ignition OFF.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2280F Pin 8
      GFD747053Courtesy of FORD MOTOR COMPANY
      		 Ground
      C2280F Pin 9

      		 Ground
      C2280F Pin 24
      GFD747053Courtesy of FORD MOTOR COMPANY
      		 Ground

    Are the resistances less than 3 ohms? 

    Yes  GO to  T9
    No  REPAIR the circuit in question.

  10. T9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Disconnect and inspect all BCM 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 BCM connectors. Make sure they seat and latch correctly.

    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new BCM. REFER to: Body Control Module (BCM) .
    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.
