Pinpoint Test G : U0155:87
- G1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
Yes GO to G2 No The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - G2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform the network test.
Does the IPC pass the network test?
Yes GO to G3 No REFER to: Communications Network - G3 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Instrumentation, Message Center and Warning Chimes No GO to G4 - G4 RECHECK THE IPMB (IMAGE PROCESSING MODULE B) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Operate the parking aid camera system and test for normal operation.
- Check the IPMB Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U0155:87 still present?
Yes GO to G5 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. - G5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0155:00 OR DTC (DIAGNOSTIC TROUBLE CODE) U0155:87 IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0155:00 or DTC U0155:87 set in any other module?
Yes GO to G6 No GO to G7 - G6 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPC 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 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, refer to IPC Hardware Testing No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues. - G7 CHECK FOR CORRECT IPMB (IMAGE PROCESSING MODULE B) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPMB 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 IPMB 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 the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new IPMB. REFER to: Image Processing Module B (IPMB) - Short Wheelbase REFER to: Image Processing Module B (IPMB) - Long Wheelbase No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
