Pinpoint Test Bf: DTC U3003:16

  1. BF1 RECHECK THE IPC DTCs 
    • Ignition ON.
    • Using a scan tool, perform the IPC self-test.
    • Clear the DTCs.
    • Repeat the IPC self-test.
    • Is DTC U3003:16 still present? 
    • Yes  : GO to BF2.
    • No  : The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
  2. BF2 CHECK FOR CHARGING SYSTEM DTCs IN THE PCM 
    • Using a scan tool, perform the PCM KOEO self-test.
    • Are any charging system DTCs set in the PCM? 
  3. BF3 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. BF4 CHECK THE IPC VOLTAGE PID 
    • Ignition ON.
    • Measure and record the voltage at the battery.
    • Using a scan tool, view the IPC PIDs.
    • Monitor the IPC voltage (MODULE_VOLT) PID.
    • Is the voltage within 0.2 volt of the recorded battery voltage? 
    • Yes  : GO to  BF7.
    • No  : GO to BF5.
  5. BF5 CHECK THE IPC VOLTAGE SUPPLY AT THE IPC 
    • Ignition OFF.
    • Disconnect: IPC.
    • Ignition ON.
    • Measure the voltage  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C220-21 SBP23 (WH/RD) - Ground

    • Is the voltage within 0.2 volt of the recorded battery voltage? 
    • Yes  : GO to BF6.
    • No  : REPAIR the circuit for high resistance.
  6. BF6 CHECK THE IPC GROUND CIRCUIT 
    • Ignition OFF.
    • Measure the resistance  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C220-5 GD374 (BK/WH) - Ground

    • Is the resistance less than 3 ohms? 
    • Yes  : GO to BF7.
    • No  : REPAIR the circuit for high resistance.
  7. BF7 CHECK FOR CORRECT IPC OPERATION 
    • Disconnect and inspect the IPC connector.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the IPC 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 TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new IPC. REFER to INSTRUMENT PANEL CLUSTER (IPC) .
    • 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.
