Pinpoint Test P : U0155:00 (SODL (Side Obstacle Detection Control Module LH) Or SODR (Side Obstacle Detection Control Module RH))

  1. DTC Fault Trigger Conditions 
    DTC Description Fault Trigger Condition
    SODR U0155:00 Lost Communication With Instrument Panel Cluster (IPC) Control Module: No Sub Type Information Sets in continuous memory when the SODL or SODR detects network messages are missing from the IPC for more than 5 seconds.

    Possible Sources 

    • Network communication concern
    • SODL
    • SODR
    • IPC

  2. P1 VERIFY THE CONCERN

    • Ignition ON.

    • Verify there is an observable symptom present.

    Is an observable symptom present? 

    Yes  GO to  P2
    No  CLEAR the DTC. The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

  3. P2 CHECK THE NETWORK COMMUNICATION

    • Using a diagnostic scan tool, carry out the network test.

    Does the IPC pass the network test? 

    Yes  GO to  P3
    No  REFER to: Communications Network .

  4. P3 CHECK FOR NON-NETWORK DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, carry out the self-test for the module in question (SODL or SODR) setting the DTC.

    Are any non-network Diagnostic Trouble Codes (DTCs) present? 

    Yes  DIAGNOSE all non-network Diagnostic Trouble Codes (DTCs) first. REFER to the DTC Chart Diagnostic Trouble Code (DTC) Chart .
    No 

  5. P4 CHECK FOR NON-NETWORK IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, carry out the IPC self-test.

    Are any non-network Diagnostic Trouble Codes (DTCs) present? 

    Yes  REFER to: Instrumentation, Message Center and Warning Chimes - Vehicles With: Head Up Display (HUD) .
    No  GO to  P5

  6. P5 RECHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0155:00

    • Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) for the module in question (SODL or SODR) setting the DTC.

    • Ignition OFF.

    • Ignition ON.

    • Wait 10 seconds.

    • Using a diagnostic scan tool, carry out the self-test for the module in question (SODL or SODR) setting the DTC.

    Is DTC U0155:00 still present? 

    Yes  GO to  P6
    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.

  7. P6 CHECK FOR OTHER CAUSES OF NETWORK COMMUNICATION CONCERN

    NOTE: If new modules were installed prior to the DTC being set, the module configuration can be incorrectly set during the PMI or the PMI may not have been carried out.

    • Check the vehicle service history for recent service actions related to the IPC and the module in question (SODL or SODR) setting the DTC. If recent service history is found:

      • verify correct replacement module was installed

        • vehicle parts build list may be used to verify correct part fitment

      • verify the configuration of replacement module was correct

        • re-configure module using as-built data if prior configuration is suspect

      • verify the module was not obtained from a like vehicle and installed into vehicle with concern

        • return the swapped module to source vehicle and obtain new replacement module

    • Operate the system and determine if the observable symptom is still present.

    Is the observable symptom still present? 

    Yes  GO to  P7
    No  The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

  8. P7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the IPC connector.

    • Repair:

      • corrosion (install new connectors 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 service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, Refer to IPC Guided Routine Testing .
    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.
