- Remove the tire.
Tightening torque: 107.9 - 127.5 N*m (11.0 - 13.0 kgf*m, 79.6 - 94.0 lb*ft)
Warning
Be careful not to damage the hub bolts when removing the wheel & tire.
- Remove the wheel speed sensor bolt (A).
Tightening torque: 6.8 - 10.7 N*m (0.7 - 1.1 kgf*m, 5.0 - 7.9 lb*ft)
- Remove the wheel speed sensor bracket bolt (A).
Tightening torque : 8.8 - 13.7 N*m (0.9 - 1.4 kgf*m, 6.5 - 10.1 lb*ft)
- Remove the front wheel guard.
(Refer to body - "Front Wheel Guard")
- Disconnect the front wheel speed sensor.
- Installation is the reverse of removal.
Inspection
- Measure the output voltage between the terminal of the wheel speed sensor and the body ground.
Warning
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
