Repair Procedures: Inspection

1. Turn ignition switch OFF and disconnect the negative (-) battery cable.
2. Measure the output voltage between the terminal of the wheel speed sensor and the body ground.
   NOTE:

   • To protect the wheel speed sensor when measuring the output voltage, a 100Ω resistor must be used as shown below.
