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:
6.9 ~ 10.8 N.m (0.7 ~ 1.1 kgf.m, 5.1 ~ 8.0 lb-ft)

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 ? 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
