Pinpoint Test BC: DTC U3003:16

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector
NOTE: Failure to disconnect the battery when instructed results in false resistance readings. Refer to BATTERY, MOUNTING AND CABLES .
  1. BC1 RECHECK THE IPC DTCs 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: IPC  Self-Test.
    • Clear the DTCs.
    • Wait 10 seconds.
    • Repeat the IPC  self-test.
    • Is DTC U3003:16 still present? 
    • Yes:  GO to BC2  .
    • No:  The system is operating correctly at this time. The DTC may have been set dueto a previous low battery voltage condition.
  2. BC2 CHECK FOR CHARGING SYSTEM DTCs IN THE PCM 
    • Enter the following diagnostic mode on the scan tool: PCM Self-Test.
    • Carry out the PCM Key ON Engine OFF (KOEO) self-test.
    • Retrieve the continuous memory DTCs from all modules.
    • Is DTC P0620, P0622, P0625, P0626 or P065B set in the PCM? 
  3. BC3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE 
    • Check the battery condition and verify the battery is fully charged. Refer to BATTERY, MOUNTING AND CABLES .
    • Is the battery OK and fully charged? 
  4. BC4 CHECK THE IPC VOLTAGE PID 
    • Ignition ON.
    • Measure and record the voltage at the battery.
    • Enter the following diagnostic mode on the scan tool: IPC  DataLogger.
    • Monitor the IPC  voltage PID (MODULE_VOLT).
    • Is the voltage within 0.2 volt of the recorded battery voltage? 
    • Yes:  GO to  BC7.
    • No:  GO to BC5  .
  5. BC5 CHECK THE IPC VOLTAGE SUPPLY 
    • Ignition OFF.
    • Disconnect: IPC  C220.
    • Ignition ON.
    • Measure the voltage between the IPC  C220-21, circuit SBP11 (BU/RD), harness side and ground.

    • Is the voltage within 0.2 volt of the recorded battery voltage? 
    • Yes:  GO to BC6  .
    • No:  REPAIR circuit SBP11 (BU/RD) for high resistance. CLEAR the DTC. REPEAT the self-test.
  6. BC6 CHECK THE IPC GROUND CIRCUIT 
    • Ignition OFF.
    • Disconnect: Negative Battery Cable.
    • Measure the resistance between the IPC  C220-5, circuit GD115 (BK/GY), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes:  GO to BC7  .
    • No:  REPAIR circuit GD115 (BK/GY) for high resistance. CLEAR the DTCs. REPEAT the self-test.
  7. BC7 CHECK FOR CORRECT IPC OPERATION 
    • Disconnect the IPC  connector.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect the IPC  connector and make sure it seats correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new IPC  . REFER to INSTRUMENT PANEL CLUSTER (IPC) . 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.
