WARNING: This page is about a different car, the 2018 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

  1. G1 CHECK THE COMMUNICATION NETWORK

    • Ignition ON.

    • Using the diagnostic scan tool, carry out the Network Test.

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

    • Retrieve and record all ABS module Continuous Memory Diagnostic Trouble Codes (CMDTCs).

    • Clear the Continuous Memory Diagnostic Trouble Codes (CMDTCs).

    • Ignition OFF.

    • Ignition ON.

    • Repeat the ABS module self-test.

    Is DTC U0151:00 retrieved again? 

    Yes  GO to  G3
    No  For Diagnostic Trouble Codes (DTCs) C0061:28, 2F, 64; C0062:28, 64; C0063:28, 2F, 64; U0028:88 or U0452:86, GO to  G7 For all other Diagnostic Trouble Codes (DTCs), GO to DTC Chart: Anti-Lock Brake System (ABS) Module . If no Diagnostic Trouble Codes (DTCs) return, 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. G3 REVIEW THE RECORDED ABS (ANTI-LOCK BRAKE SYSTEM) MODULE SELF-TEST DIAGNOSTIC TROUBLE CODES (DTCS)

    • Review the recorded Diagnostic Trouble Codes (DTCs) from the ABS module self-test.

    Is DTC U3003:16 or U3003:17 recorded in the RCM? 

    Yes  REFER to: Airbag Supplemental Restraint System (SRS) .
    No  GO to  G5

  5. G5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0151:00 SET IN OTHER MODULES

    Does the part number on the RCM match the part number listed in the parts catalog? 

    Yes  GO to  G7
    No  INSTALL the correct RCM. REFER to: Restraints Control Module (RCM) .

  7. G7 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) CALIBRATION ROUTINE

    • Using a diagnostic scan tool, carry out the IVD Initialization routine. Follow the diagnostic scan tool instructions.

    Does the ABS module IVD Initialization complete successfully? 

    Yes  GO to  G8
    No  GO to  G9

  8. G8 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition OFF.

    • Ignition ON.

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

    Are any stability control sensor Diagnostic Trouble Codes (DTCs), including no communication, invalid data and bus off Diagnostic Trouble Codes (DTCs) present? 

    Yes  GO to  G9
    No  The condition that set the DTC is not present at this time. The concern may have been caused due to a failed or an incomplete initialization.

  9. G9 CHECK THE PRIVATE HS-CAN (HIGH-SPEED CONTROLLER AREA NETWORK) CIRCUITS FOR A SHORT TO VOLTAGE

    WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Ignition must remain OFF until repair is complete. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.

    • Ignition OFF and wait one minute.

    • Disconnect RCM C310A and C310B.

    • Disconnect ABS module C135.

    • Ignition ON.

    • Measure:

    • Disconnect and inspect RCM C310A and C310B (if not previously disconnected).

    • Repair:

      • corrosion (install new connector or terminal - clean module pins)
      • damaged or bent pins - install new terminals or pins
      • pushed-out pins - install new pins as necessary

    • Connect RCM C310A and C310B. Make sure the connectors seat and latch correctly.

    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RCM. REFER to: Restraints Control Module (RCM) .
