Pinpoint Test G: DTC (Diagnostic Trouble Code) U0155:00

G1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
1. Yes : GO to G2
2. 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 a network test.
Does the IPC pass the network test?
1. Yes : GO to G3
2. No : DIAGNOSE no communication with the IPC .
  REFER to: COMMUNICATIONS NETWORK .
G3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BODY CONTROL MODULE (BCM) SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Is DTC U3003:16 or DTC U3003:17 recorded?
1. Yes : For DTC U3003:16, GO to PINPOINT TEST O
  For DTC U3003:17, GO to PINPOINT TEST P
2. No : GO to G4
G4 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE INSTRUMENT PANEL CLUSTER (IPC) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U3006:16 or DTC U3006:17 recorded?
1. Yes : REFER to: INSTRUMENTATION, MESSAGE CENTER AND WARNING CHIMES .
2. No : GO to G5
G5 RECHECK THE BODY CONTROL MODULE (BCM) DIAGNOSTIC TROUBLE CODES (DTCS)
NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during the PMI or the PMI may not have been carried out.
- Clear the Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, perform the BCM self-test.
Is DTC U0155:00 still present?
1. Yes : GO to G6
2. 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.
G6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0155:00 SET IN OTHER MODULES
- Clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U0155:00 set in any other module?
1. Yes : GO to G7
2. No : GO to G8
G7 CHECK FOR CORRECT INSTRUMENT PANEL CLUSTER (IPC) OPERATION
- Disconnect and inspect 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
- Connect 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?
1. 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) .
2. 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.
G8 CHECK FOR CORRECT BODY CONTROL MODULE (BCM) OPERATION
- Disconnect and inspect all BCM 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
- Connect the BCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
1. 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 BCM .
  REFER to: BODY CONTROL MODULE (BCM) .
2. 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.
