Inspection
1.

Measure the output voltage between the terminal of the wheel speed sensor and the body ground.

  

In order to protect the wheel speed sensor, when measuring output voltage, a 100 Ω resister must be used as shown.

2.

Compare the change of the output voltage of the wheel speed sensor to the normal change of the output voltage as shown below.

V_low : 0.59V - 0.84V

V_high : 1.18V - 1.68V

Frequency range : 1 - 2,500Hz
