Pinpoint Test Bf: DTC U3003:16

• 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.

• Using a scan tool, perform the PCM KOEO  self-test.

Are any charging system DTCs set in the PCM? 

• Yes  : REFER to CHARGING SYSTEM .
• No  : GO to BF3  .

• 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? 

• Yes  : GO to BF4  .
• No  : REFER to BATTERY, MOUNTING AND CABLES .

• 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  .

• 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.

• 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.

• 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.
