Pinpoint Test Co : U3003:16

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

  1. CO1 RECHECK THE IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition ON.

    • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).

    • Wait 10 seconds.

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

    Is DTC U3003:16 still present? 

    Yes  GO to  CO2
    No  The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.

  2. CO2 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS) IN THE BCM (BODY CONTROL MODULE)

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

    Are any charging system Diagnostic Trouble Codes (DTCs) recorded? 

    Yes  REFER to: Body Control Module (BCM) .
    No  GO to  CO3

  3. CO3 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  CO4
    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 .

  4. CO4 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) VOLTAGE PID

    • Measure and record the voltage at the battery.

    • Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).

    • Monitor the IPC voltage (MODULE_VOLT) PID

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

    Yes  GO to  CO7
    No  GO to  CO5

  5. CO5 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) VOLTAGE SUPPLY

    • Ignition OFF.

    • Disconnect IPC C220.

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C220-8

      		 Ground

    Is the voltage greater than 11 volts? 

    Yes  GO to  CO6
    No  REPAIR the circuit for high circuit resistance.

  6. CO6 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) GROUND

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C220-8
      GFD465489Courtesy of FORD MOTOR COMPANY
      		 C220-3

    Is the voltage greater than 11 volts? 

    Yes  GO to  CO7
    No  REPAIR the circuit for high circuit resistance.

  7. CO7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the IPC connector and related in-line 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 IPC connector and related in-line connectors. Make sure it seats and latches correctly.

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

    Is the concern still present? 

    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, Refer to IPC Guided Routine Testing .
    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.
