Inspection

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

   

2. 2
   Compare the wheel speed sensor output voltage change with the normal output voltage change as shown below.

   

   V_low: 0.59 V ~ 0.84 V V_high: 1.18 V ~ 1.68 V Frequency range: 1 ~ 2500 Hz
