Measure the output voltage between the terminal of the wheel speed sensor and the body ground.
In order to protect the wheel speed sensor, when measuring output voltage, a 100 Ω 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 voltage as shown below.
V_low : 0.59V ~ 0.84V
V_high : 1.18V ~ 1.68V
Frequency range :
- Active type(connector color: white) : 1 ~ 2.500Hz
- Smart Active type(connector color: Black):
1 ~ 2,500Hz, 2,500 ~ 5,000Hz
