Repair procedures
1. |
Loosen the wheel nuts slightly.
Raise the vehicle, and make sure it is securely supported.
|
2. |
Remove the front wheel and tire (A) from front hub .
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 the hub bolts when removing
the front wheel and tire (A).
|
|
|
3. |
Loosen the mounting holt and then remove the wheel speed sensor cable
from the strut assembly.
Tightening torque :
8.8 - 13.7 N.m(0.9 - 1.4 kgf.m, 6.5 - 10.1 lb-ft)
|

|
4. |
Remove the wheel speed sensor cable braket bolt (A).
Tightening torque :
7.8 - 11.8 N.m (0.8 - 1.2 kgf.m, 5.8 - 8.7 lb-ft)
|

|
5. |
Remove the front wheel guard.
|
6. |

|
7. |
Loosen the bolt and then remove the wheel speed sensor (A).
Tightening torque :
6.9 - 10.8 N.m (0.7 - 1.1 kgf.m, 5.1 - 8.0 lb-ft)
|

|
8. |
To install, reverse the removal procedure.
|
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 100Ω 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 - 2,500 Hz

A low aspect ratio tyre, of which the
aspect ratio is lower than 50, is
designed for a sporty-look vehicle.
The low aspect ratio is to optimize
handling and braking. Thus, it may
be uncomfortable to ride and it may
generate noises, in comparison with
a normal tyre...
