Removal

1. | Remove the front wheel and tire.

Tightening torque:
88.3 ~ 107.9 N.m (9.0 ~ 11.0 kgf.m, 65.1 ~ 79.6 lb-ft)

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

Tightening torque:
7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)

3. | Remove the front wheel guard .

4. | Remove the front wheel speed sensor cable mounting bolt (A).

5. | Disconnect the front wheel speed sensor connector, then remove the front wheel speed sensor.

6. | Installation is the reverse of removal.

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
