Wheel Speed Sensor

Wheel speed sensor





The sensors are active, which means that they have a built in electronic circuit. The control module transmits a voltage of U (bat), the sensor sends back a digital power signal of 7 or 14 mA, depending on position. This solution gives a more robust signal, compared to the voltage signal. The current flow over the connections is higher which minimizes the chance of corrosion.

Pulse wheel
S/V 70 have 48 toothed magnetic pulse wheels on all four wheels.

Control module





There are three versions of the control module available:
^ ABS
^ ABS+TC
^ ABS+STC (the control modules are not programmable).
