Be careful not to damage the parts located under the vehicle
(floor under cover, fuel filter, fuel tank and canister) when
raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
|
|
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 the 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. |
Remove the front wheel guard.

Loosen the bolt and then 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)
|

|
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.

• Ⅰlow : 5.95 ~ 8.05 mA
• ⅠHIgh : 11.9 ~ 16.1 mA
• Frequency range : 0.03 ~ 3000 HZ
