Removal

1.	Loosen the wheel nuts slightly. Raise the vehicle, and make sure it is securely supported.

Remove the rear 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 rear wheel and tire (A).

3.	Disconnect the rear wheel speed sensor connector(A).

Loosen the mounting bolt and then remove the wheel speed sensor cable bracket (A) and (B).

Inspection

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.

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
