  1. R1: CHECK THE COMMUNICATION NETWORK 
    • 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
      Go to  R2. DIAGNOSE the no communication with the CCM.
      Refer to Module Communications Network article.
  2. R2: RECHECK FOR THE ABS MODULE DTCS 
    • Clear the ABS DTCs.
    • Ignition OFF.
    • Ignition ON, engine OFF.
    • Carry out the ABS self-test.
    • Is DTC U0104:xx or U0405:xx retrieved again? 
      Yes No
      Go to  R3. 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. R3: 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 .      		 For Flex NOT equipped with adaptive cruise control, Go to  R5.
      For Flex equipped with adaptive cruise control, Go to  R4.
      For MKT NOT equipped with adaptive cruise control, Go to  R5.
      For MKT equipped with adaptive cruise control, Go to  R4.
      For Taurus NOT equipped with adaptive cruise control, Go to  R5.
      For Taurus equipped with adaptive cruise control, Go to  R4.
      For all others, Go to  R4.
  4. R4: 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 Cruise Control article. Go to  R6.
  5. R5: CHECK FOR DTCS IN THE PCM 
    • Carry out the PCM KOEO self-test.
    • Are any DTCs present? 
      Yes No
      DIAGNOSE the PCM DTCs. REFER to applicable Electronic Engine Controls 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 or U0405:xx set in 1 or more modules in addition to the ABS module? 
      Yes No
      For Flex NOT equipped with adaptive cruise control, Go to  R9.
      For Flex equipped with adaptive cruise control, Go to  R8.
      For MKT NOT equipped with adaptive cruise control, Go to  R9.
      For MKT equipped with adaptive cruise control, Go to  R8.
      For Taurus NOT equipped with adaptive cruise control, Go to  R9.
      For Taurus equipped with adaptive cruise control, Go to  R8.
      For all others, Go to  R8.      		 Go to  R10.
  8. R8: CHECK FOR CORRECT CCM OPERATION 
    • Ignition OFF.
