Removal
1. | Remove the front 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 front wheel speed sensor mounting bolt (A).
Tightening torque: 7.8 ~ 11.8 N.m (0.8 ~ 1.2 kgf.m, 5.9 ~ 8.7 lb-ft)
3. | Remove the front wheel guard.
4. | Remove the front wheel speed sensor cable mounting bolt.
5. | Disconnect the front wheel speed sensor connector (A) and then remove the front wheel speed sensor.
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
