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
