Remove the front wheel & tire.

Tightening torque:

107.9 - 127.5 N·m (11.0 - 13.0 kgf·m, 79.6 - 94.0 lb·ft)

Loosen the bolt (A) and then disconnect the wheel speed sensor.

Tightening torque :

7.8 - 11.8 N·m (0.8 - 1.2 kgf·m, 5.8 - 8.7 lb·ft)

3.	Remove the front wheel guard. (Refer to Body - "Front Wheel Guard")

4.	Disconnect the wheel speed sensor connector (A).

Inspection

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.

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
