Pinpoint Test CB : U3003:16

  1. CB1 RECHECK THE ICM (INFORMATION CENTER MODULE) 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  CB2
    No  Clear the DTC. The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.

  2. CB2 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  CB3

  3. CB3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE

    Is the battery OK and fully charged? 

    Yes  GO to  CB4
    No  If the battery is discharged, DIAGNOSE the cause of the low battery condition. REFER to: BATTERY, MOUNTING AND CABLES .

  4. CB4 CHECK THE ICM (INFORMATION CENTER MODULE) VOLTAGE SUPPLY

    • Ignition OFF.
    • Ignition ON.
    • Measure:
      Positive Lead Measurement / Action Negative Lead

      		 Ground

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

    Yes  GO to  CB5
    No  REPAIR the circuit for high circuit resistance.

  5. CB5 CHECK THE ICM (INFORMATION CENTER MODULE) GROUND

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2114-1
      GFD5390Courtesy of FORD MOTOR COMPANY
      		 C2114-4

    Is the voltage greater than 11 volts? 

    Yes  GO to  CB6
    No  REPAIR the circuit for high circuit resistance.

  6. CB6 CHECK FOR CORRECT ICM (INFORMATION CENTER MODULE) OPERATION

    • Ignition OFF.
    • Disconnect and inspect the ICM connector.
    • 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 ICM connector. 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, INSTALL a new ICM. REFER to: Information Center Module (ICM) .
    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.
