Inspection

1. 1

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

   

2. 2

   Compare the change in the wheel speed sensor output voltage with the normal output voltage change, as shown below.

   

   V_low: 0.59–0.84 V V_high: 1.18–1.68 V Frequency range: 1–2,500 Hz
