  7. AD7: CHECK THE ABS MODULE ROLL RATE PID 
    NOTE: The vehicle must be on level ground and at a complete standstill. Any vehicle movement results in false values for this test.
    • Access the ABS and monitor the ROLL_RATE (ANGV) PID.
    • Is the ROLL_RATE PID value between -0.4 and 0.4? 
      Yes No
      Go to  AD8. Go to  AD15.
  8. AD8: CHECK THE ABS MODULE LATERAL ACCELEROMETER (LAT_ACCL) PID 
    NOTE: The vehicle must be on level ground and at a complete standstill. Any vehicle movement results in false values for this test.
    • Access the ABS and monitor the LAT_ACCL (ACC) PID.
    • Is the LAT_ACCL PID value between -0.4 and 0.4? 
      Yes No
      For Edge, Go to  AD9.
      For all others, Go to  AD10.      		 Go to  AD15.
  9. AD9: CHECK THE ABS MODULE LONGITUDINAL ACCELEROMETER SENSOR INPUT (LNGACC) PID 
    • Access the ABS and monitor the LNGACC (ACC) PID.
    • Is the LNGACC PID value between -0.4 and 0.4? 
      Yes No
      Go to  AD11. Go to  AD15.
  10. AD10: CHECK THE ABS MODULE LONGITUDINAL ACCELEROMETER SENSOR INPUT (LONG_ACCL) PID 
    • Access the ABS and monitor the LONG_ACCL (ACC) PID.
    • Is the LONG_ACCL PID value between -0.4 and 0.4? 
      Yes No
      For MKC. Go to  AD12.
      For all others, Go to  AD11.      		 Go to  AD15.
  11. AD11: CHECK THE ABS MODULE STEERING WHEEL ANGLE SENSOR (STEER_ANGL) PID 
    • Access the ABS and monitor the STEER_ANGL (ANGL) PID.
    • Slowly rotate the steering wheel one complete revolution to the left and then one complete revolution to the right.
    • Does the PID change in intervals of 4.5 degrees and show a 360-degree increase for each complete revolution of the steering wheel? 
      Yes No
      For Edge. Go to  AD13.
      For all others, Go to  AD15.      		 Go to PINPOINT TEST AJ .
  12. AD12: CHECK THE ABS MODULE STEERING WHEEL ANGLE SENSOR (STR_ANG_ABS) PID 
    • Access the ABS and monitor the STR_ANG_ABS (ANGL) PID.
    • Slowly rotate the steering wheel one complete revolution to the left and then one complete revolution to the right.
    • Does the PID change in intervals of 4.5 degrees and show a 360-degree increase for each complete revolution of the steering wheel? 
      Yes No
      Go to  AD15. Go to PINPOINT TEST AJ .
  13. AD13: VERIFY ALL WIRING CONNECTIONS 
    WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
    • Ignition OFF.
    • Wait one minute.
    • RCM_A connector disconnected. (C310A)

    • Disconnect all in-line electrical connectors between the ABS module and the RCM.
    • 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
    • Are the connectors free of corrosion, damaged pins, bent pins, pushed-out pins and spread terminals? 
      Yes No
      Go to  AD14. REPAIR the connector or terminals. Refer to OEM CONNECTOR REPAIR PROCEDURES , for schematic and connector information.
  14. AD14: CHECK FOR CORRECT ABS MODULE OPERATION

    • RCM_A connector connected. (C310A) Make sure it seats and latches correctly.
    • Connect all in-line electrical connectors between the ABS module and the RCM. Make sure they seat and latch 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 applicable Technical Service Bulletins TSBs.

      If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions.

      If no TSBs address this concern, INSTALL a new ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL .

      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.


      When complete, SELECT the "X" in the top right corner to CLOSE this procedure.      		 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.

      If this is a Ford paid repair, INCLUDE the RVC on the warranty claim form.


      When complete, SELECT the "X" in the top right corner to CLOSE this procedure.
  15. AD15: CHECK THE RCM INSTALLATION AND MOUNTING SURFACE 
    WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
    • Ignition OFF.
    • Wait one minute then disconnect the RCM connectors.
    • Inspect the RCM installation and verify all fasteners are tighten to specifications.
    • Inspect the RCM mounting surface for damage, corrosion, dirt and other irregularities.
    • Is the RCM installed correctly and the mounting surface clean and free from damage? 
      Yes No
      INSTALL a new RCM. REFER to SUPPLEMENTAL RESTRAINT SYSTEM . CLEAR or REPAIR the RCM mounting surface as necessary. TIGHTEN the fasteners to the correct toque specification.
