Normal Operation and Fault Conditions

With the ignition ON, the CCM sends messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC. For information on the messages sent to the ABS module by the CCM, refer to the Network Message Chart in Description and Operation of the Anti-Lock Brake System (ABS) and Stability Control article. 

DTC DESCRIPTION

DTC Description Fault Trigger Conditions
U0104:00 Lost Communication With Cruise Control Module: No Sub Type Information Sets when the ABS module detects any of the CCM messages are missing. This can be due to a CCM failure, a circuit failure on the HS-CAN or an excessive load on the network.
U0405:41 Invalid Data Received From Cruise Control Module: General Checksum Failure This DTC sets if the collision mitigation by braking deceleration message checksum is invalid. This can be due to a CCM failure, a circuit failure on the HS-CAN or an excessive load on the network.
U0405:82 Invalid Data Received From Cruise Control Module: Alive/Sequence Counter Incorrect/Not Updated This DTC sets if the collision mitigation by braking deceleration message count is out of range. This can be due to a CCM failure, a circuit failure on the HS-CAN or an excessive load on the network.
U0405:86 Invalid Data Received From Cruise Control Module: Signal Invalid This DTC sets if the CCM is requesting an external apply of the electric parking brake and the vehicle is not in static mode. This can be due to a CCM failure, a circuit failure on the HS-CAN or an excessive load on the network.
U2107:00 Collision Mitigation By Braking: No Sub Type Information This DTC sets when the collision deceleration message from the CCM is sent too often or the duration of the message is too long. This is most likely caused by a network communication concern or an internal failure of the CCM.

  1. R1: CHECK THE MODULE COMMUNICATION 
    • Ignition ON, engine OFF.
    • Press the Read Vehicle Information button to view the results of the modules communicating on the network.
    • Retrieve the continuous memory DTCs.
    • 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.
  2. R2: CHECK THE IPMA COMMUNICATION NETWORK 
    • Review the results of the modules communicating on the network from the previous step.
    • 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.
  3. R3: RECHECK FOR THE ABS MODULE DTCS 
    • Clear the ABS DTCs.
    • Ignition OFF.
    • Ignition ON, engine OFF.

    Carry out the ABS self-test.

    • 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 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  R6.
  6. R6: 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  R7. The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.
  7. R7: 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? 
    Yes No
    Go to  R8. Go to  R9.
  8. R8: CHECK FOR CORRECT CCM OPERATION 
    • Ignition OFF.
      NOTE: The battery must be removed to access the ABS module electrical connector.
