Repair procedures
Removal and Installation
1.

Disconnect the battery negative terminal.

2.

Remove the front wheel and tire (A).

Tightening torque:

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

  

Be careful not to damage to the hub bolts when removing the front wheel and tire.

3.

Disconnect the front wheel speed sensor (A).

Tightening torque :

8.8 - 13.7 N·m (0.9 - 1.4 kgf·m, 6.5 - 10.1 lb·ft)

4.

Disconnect the front wheel speed sensor brackets (A) by loosening the bolts.

Tightening torque :

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

Bolt (C) : 8.8 - 13.7 N·m (0.9 - 1.4 kgf·m, 6.5 - 10.1 lb·ft)

5.

Remove the front wheel guard.

(Refer to Body - "Front Wheel Guard")

6.

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
