- Using a scan tool, clear Diagnostic Trouble Codes (DTCs).
- Operate the system and test the system for normal operation.
- Using a scan tool, repeat Image Processing Module - B (IPM-B) self-test.
Is DTC U0155:87 still present?
- Yes: GO to W5
- 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.
W5 CHECK FOR BATTERY VOLTAGE OUT OF RANGE DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a scan tool, retrieve continuous memory Diagnostic Trouble Codes (DTCs) from all modules.
Is DTC U3006:16 or U3006:17 set in the Image Processing Module - B (IPM-B)?
- Yes: For DTC U3006:16, GO to Pinpoint Test X
  For DTC U3006:17, GO to Pinpoint Test Y
- No: GO to W6
W6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0155 IN OTHER MODULES
- Using a scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Wait 10 seconds.

Is DTC U0155:00 or U0155:87 present in any other module?
- Yes: INSTALL a new BCM.
  REFER to: BODY CONTROL MODULE (BCM) .
- No: GO to W7
W7 CHECK FOR CORRECT IMAGE PROCESSING MODULE - B (IPM-B) OPERATION
- 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.
