  1. R1: CHECK THE IPMA COMMUNICATION NETWORK 
    • Press the Read Vehicle Information button to view the results of the modules communicating on the network.
    • Retrieve the continuous memory DTCs.
    • Did the IPMA pass the Network Test? 
      Yes No
      RETRIEVE and RECORD all IPMA DTCs. REFER to the Rear View Mirrors article. If there are no DTCs in the IPMA,
      Go to  R3.      		 DIAGNOSE the no communication concern with the IPMA. REFER to the Module Communications Network article.
  2. R2: CHECK THE MODULE COMMUNICATION 
    • Ignition ON, engine OFF.
    • Review the results of the modules communicating on the network from the previous step.
    • Does the CCM pass the Network Test? 
      Yes No
      RETRIEVE and RECORD all CCM DTCs. REFER to the appropriate Cruise Control article. If there are no DTCs in the CCM,
      Go to  R3.      		 DIAGNOSE the CCM does not communicate with the diagnostic scan tool. REFER to the Module Communications Network article.
  3. R3: RECHECK FOR THE ABS MODULE DTCS 
    • Clear the ABS DTCs.
    • Ignition OFF.
    • Ignition ON, engine OFF.

      Carry out the ABS self-test.

    • Record all ABS module DTCs.
    • Are any of the DTCs listed in the DTC Fault Trigger Conditions Table retrieved again? 
      Yes No
      Go to  R4. The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
  4. R4: CHECK FOR DTC U3003:16 AND U3003:17 
    • Review the results from the ABS module self-test.
    • Is DTC U3003:16 or U3003:17 present? 
      Yes No
      For DTC U3003:16, GO to PINPOINT TEST A .
      For DTC U3003:17, GO to PINPOINT TEST F .      		 Go to  R5.
  5. R5: CHECK FOR DTCS IN THE IPMA 

    Carry out the IPMA self-test.

    • Are any DTCs present? 
      Yes No
      DIAGNOSE the IPMA DTCs. REFER to the appropriate Lane Keeping System article. Go to  R7.
  6. R6: CHECK FOR DTCS IN THE CCM 

    Carry out the C-CM self-test.

    • Are any DTCs present? 
      Yes No
      DIAGNOSE the CCM DTCs. REFER to the appropriate Cruise Control article. Go to  R7.
  7. R7: CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK 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 CCM or ABS module. If recent service history is found:
      • Verify the correct replacement module was installed - HVBOM may be used to verify correct part fitment.
      • Verify the configuration of replacement module was correct - re-configure the module using as-built data if prior configuration is suspect.
      • Verify the module was not obtained from a like vehicle and installed into customer vehicle - 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 No
      Go to  R8. The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.
  8. R8: CHECK FOR COMMUNICATION DTCS IN OTHER MODULES 
    • Retrieve the continuous memory DTCs.
    • Is DTC U0104:xx, U0405:xx or U2107:xx set in 1 or more modules in addition to the ABS module? 
  9. R9: CHECK FOR CORRECT CCM OPERATION 
    • Ignition OFF.
      NOTE: The battery must be removed to access the ABS module electrical connector.
    • Remove the battery. Refer to the appropriate procedure in the Battery, Mounting and Cables article.
    • conn_eauger_1479227526_acronymCCM#1acronym (Cruise Control Module) connector disconnected.
    • ABS Module connector disconnected. (C135)
    • Using a good light source, inspect all disconnected electrical connectors for the following:
      • corrosion - install new connector or terminal and clean the module pins
      • damaged or bent pins - install new terminals or pins
      • pushed-out pins - install new pins as necessary
      • spread terminals - install new terminals as necessary
    • ABS Module connector connected. (C135) Make sure the connector seats and latches correctly.
