Removal
1.
Remove the rear wheel and tire.

Tightening torque:
88.3 ~ 107.9 N.m (9.0 ~ 11.0 kgf.m, 65.1 ~ 79.6 lb-ft)

2.
Remove the rear wheel speed sensor mounting bolt (A).

Tightening torque:
6.9 ~ 10.8 N.m (0.7 ~ 1.1 kgf.m, 5.0 ~ 8.0 lb-ft)

3.
Remove the rear seat back.
(Refer to the Body group - Seat)
4.
Remove the rear wheel housing trim.
(Refer to the Body group – interior trim)
5.
Disconnect the rear wheel speed sensor connector.
6.
Installation is the reverse of removal.
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: 0.59 ~ 0.84 V
V_high: 1.18 V ~ 1.68 V
Frequency range: 1 ~ 2,500 Hz
