   Waveform 1 (Reference):

   Item	Condition
   Tool setting	5 V/DIV., 20 ms./DIV.
   Vehicle condition	Power switch on (IG), wheel being rotated

   Tip:

   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.
