  8.  
  9. Is the measured waveform within specifications-
    1. If YES:

      Fault is intermittent caused by poor connection in wheel speed sensor harness or external noise.
       
      Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage and external noise, or interference between harnesses.
       
      Repair or replace as necessary.
       
      If OK, substitute with a known good Hydraulic and Electronic Control Module (HECU) and check for proper operation. If problem is corrected, replace the HECU.
       

    2.  
    3. If NO:

      Check for improper installation of wheel speed sensor. Repair as necessary.
       
      Check for damage of rotor teeth or wheel bearing. Repair as necessary.
       
      Substitute with a known good wheel speed sensor and check for proper operation. If problem is corrected, replace the wheel speed sensor.
