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

Are any Diagnostic Trouble Codes (DTCs) present? 

• Yes  : REFER to: BODY CONTROL MODULE (BCM) .
• No  : GO to Z4 

• Clear the Diagnostic Trouble Codes (DTCs).
• Operate the system and test the system for normal operation.
• Repeat the Image Processing Module - B (IPM-B) self-test.

Is DTC U0140:87 still present? 

• Yes  : GO to Z5 
• No  : The system is operating correctly at this time. The DTC  may have been set due to high network traffic or an intermittent fault condition.

Is DTC U0140:00 or DTC U0140:87 set in any other module? 

• Yes  : INSTALL a new BCM  .

  REFER to: BODY CONTROL MODULE (BCM) .

• No  : GO to Z6 

• Ignition OFF.
• Disconnect and inspect the Image Processing Module - B (IPM-B) 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 Image Processing Module - B (IPM-B) 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 Image Processing Module - B (IPM-B). For the 4-door,

  REFER to: IMAGE PROCESSING MODULE B (IPMB) - 4-DOOR .

  For the 5-door, REFER to: IMAGE PROCESSING MODULE B (IPMB) - 5-DOOR .

• No  : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
