Removal

1.	Remove the front wheel speed sensor mounting bolt (A).

2.	Remove the front wheel speed sensor bracket (A).

3.	Remove the front wheel guard .

4.	Disconnect the front wheel speed sensor connector (A) , then remove the front wheel speed sensor.

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 : 0.44V ~ 0.63V V_high : 0.885V ~ 1.26V Frequency range : 1 ~ 2,500Hz
