April 5, 2026: LEMON Manuals is launched! Read the announcement.

Possible Causes

  1. BV1: CHECK THE COMMUNICATION NETWORK 
    • Ignition ON, engine OFF.
    • Retrieve the continuous memory DTCs.
    • Does the SCCM pass the Network Test? 
      Yes No
      RETRIEVE and RECORD all SCCM DTCs. REFER to the Steering Wheel and Column Electrical Components article. If there are no DTCs in the SCCM, Go to  BV2. DIAGNOSE the no communication with the SCCM. REFER to the Module Communications Network article.
  2. BV2: RECHECK THE ABS MODULE DTCS 
    • Clear the ABS DTCs.
    • Ignition OFF.
    • Test drive the vehicle over 20 km/h (12 mph) and make at least one left turn and one right turn.
    • Ignition OFF.
    • Ignition ON, engine OFF.

      Carry out the ABS self-test.

    • Are any of the DTCS listed in the Fault Setting Conditions Table retrieved again? 
      Yes No
      Go to  BV3. 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. BV3: REVIEW THE RECORDED DTCS FROM THE ABS MODULE SELF-TEST 
    • Check the DTCs recorded from the ABS module self-test.
    • Was DTC U3003:16 or U3003:17 recorded? 
      Yes No
      For DTC U3003:16, GO to PINPOINT TEST A .
      For DTC U3003:17, GO to PINPOINT TEST F .      		 Go to  BV4.
  4. BV4: CHECK FOR DTCS IN THE SCCM 

    Carry out the SCCM self-test.

    • Record all DTCs from the SCCM self-test.
    • Are any DTCs present in the SCCM? 
      Yes No
      DIAGNOSE all SCCM DTCs. REFER to the Steering Wheel and Column Electrical Components article. Go to  BV5.
  5. BV5: 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 SCCM or the 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  BV6. The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.
  6. BV6: CHECK FOR COMMUNICATION DTCS IN OTHER MODULES 
    • Ignition ON, engine OFF.
    • Clear the ABS DTCs.
    • Retrieve the continuous memory DTCs.
    • Is DTC U0212:xx, U0428:xx or U0429:xx set in 1 or more modules in addition to the ABS module? 
      Yes No
      Go to  BV8. Go to  BV7.
  7. BV7: VERIFY ABS MODULE OPERATION 
    • Ignition OFF.
    • SCCM_A connector disconnected.
    • 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
    • SCCM_A connector connected. Make sure the connector seats and latches correctly.
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
      Yes No
      INSTALL a new ABS module.
      CHECK OASIS for any 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 services articles address this concern, INSTALL a new ABS module. REFER to the Anti-Lock Brake System (ABS) and Stability Control article.
      ORDER a replacement ABS module and INCLUDE the RVC on the form.
      If this is a Ford paid repair, INCLUDE the RVC on the warranty claim form.      		 The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
  8. BV8: VERIFY SCCM OPERATION 
    • Ignition OFF.
    • SCCM_A connector disconnected.
    • 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
    • SCCM_A connector connected. Make sure the connector seats and latches correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
      Yes No
      INSTALL a new SCCM.
      CHECK OASIS for any 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, INSTALL a new SCCM. REFER to the Steering Wheel and Column Electrical Components article.      		 The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
  9. BV9: VERIFY ABS OPERATION 
    • Ignition OFF.
    • ABS_A Module connector disconnected. (C135A)
    • SCCM_A connector disconnected.
    • 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
    • SCCM_A connector connected. Make sure the connector seats and latches correctly.
    • ABS_A Module connector connected. (C135A) Make sure the connector seats and latches correctly.
    • ABS_B Module connector connected. (C135B) Make sure the connector seats and latches correctly.
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
      Yes No
      INSTALL a new EBB assembly.
      The HCU and ABS module are a single assembly known as the EBB unit.
      CHECK OASIS for any 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, INSTALL a new EBB unit (HCU and ABS module assembly). REFER to the Anti-Lock Brake System (ABS) and Stability Control article. ORDER a replacement EBB unit and INCLUDE the RVC on the form.
      If this is a Ford paid repair, INCLUDE the RVC on the warranty claim form.      		 The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
