Pinpoint Test A: The IPC (Instrument Panel Cluster) Is Inoperative

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

Is DTC U3010:01 recorded? 

• Yes  : REFER to: STEERING WHEEL AND COLUMN ELECTRICAL COMPONENTS .
• No  : GO to A2 

• Ignition OFF.
• Disconnect IPC C220A  .
• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C220A-32		Ground

Is the voltage greater than 11 volts? 

• Yes  : GO to A3 
• No  : VERIFY the CJB  fuse 3 (7.5A) is OK. If OK, REPAIR the circuit for an open. If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short. TEST the system for normal operation.

• Ignition ON.
• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C220A-4		Ground

Is the voltage greater than 11 volts? 

• Yes  : GO to A4 
• No  : VERIFY the CJB  fuse 21 (7.5A) is OK. If OK, REPAIR the circuit for an open. If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short. TEST the system for normal operation.

• Accessory ON.
• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C220A-15		Ground

Is the voltage greater than 11 volts? 

• Yes  : GO to A5 
• No  : VERIFY the CJB  fuse 19 (7.5A) is OK. If OK, REPAIR the circuit for an open. If not OK, REFER to the SYSTEM WIRING DIAGRAMS to identify the possible causes of the circuit short. TEST the system for normal operation.

• Ignition OFF.
• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C220A-32		C220A-6

Is the voltage greater than 11 volts? 

• Yes  : GO to A6 
• No  : REPAIR the circuit.

• Ignition OFF.
• Disconnect and inspect the IPC  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  connectors. Make sure they seat and latch 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 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.
