Inspection

Inspection

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

WARNING

In order to protect the wheel speed sensor, when measuring output voltage, a 100Q resister must be used as shown.

Compare the change of the output voltage of the wheel speed sensor to the normal change of the output voltase as shown below.

I low : 5.95 ~ 8.05 mA
I High : 11.9- 16.1 mA
Frequency range : 0.03 ~ 3000 HZ
