    2. A01DRHUE03

      Waveform 1 (Reference): Using an oscilloscope:

      Item Condition
      Tool setting 5 V/DIV., 20 ms./DIV.
      Vehicle condition Driving at approximately 20 km/h (12 mph)

      Tech Tips

      When the system is functioning normally, one wheel revolution generates 4 pulses. As the vehicle speed increases, the width indicated by (A) in the illustration narrows.
