ABS/ESC - C1213 Wheel Speed Frequency Error - Component Inspection

Component Inspection

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

Specification : High : 1.05 V, Low : 0.525 V
Compare waveforms of all wheel speed sensors.
If it is the same as another parameters, it is in normal condition.




5. Is the measured waveform within specifications?
