Repair Procedures

Removal

1. Remove the front wheel speed sensor mounting bolt (A) and the wire bracket mounting bolt (B).




2. Remove the wire bracket bolt (A).




3. Remove the front wheel guard.
4. Remove the front wheel speed sensor after disconnecting the wheel speed sensor connector (A).






Inspection

1. Measure the output voltage between the terminal of the wheel speed sensor and the body ground.

CAUTION:
In order to protect the wheel speed sensor, when measuring output voltage, a 75Ohms resistor 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.




A. V_low : 0.67 V ~ 1.0 V
B. V_high : 1.34 V ~ 2.02 V
C. Frequency range : 1 - 2,500 Hz
