Component Inspection

Wheel speed sensor circuit check
1. Lift the vehicle.
2. Ignition "ON" & Engine "OFF".
3. Turn the wheel by hand.
4. Measure waveform between signal terminal of the wheel speed sensor harness connector and chassis ground with osciloscope.

Specification :High : 1.18 - 1.68V , Low : 0.59 - 0.84V
Compare waveforms of all wheel speed sensors.
If they have same waveform, it is in normal condition.




5. Is the measured waveform within specifications?
