Circuit/System Description
WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
For an overview of the component/system, refer to:ABS Description and Operation
| Circuit | Description |
|---|---|
| Signal | The sensor produces a frequency modulated signal. |
| Low Reference | Grounded through the control module. |
| Component | Description |
|---|---|
| B5 Wheel Speed Sensor | The sensor contains a hall-effect sensor and additional electronics that processes the signal. It detects the change of strength of the magnetic field caused by the reluctor ring. When the strength changes, the sensor changes the amount of current it consumes. This results in a square wave signal of the current, while the voltage stays constant. The control module detects the frequency in which the current changes, which is proportional to the rotational speed. |
| K17 Electronic Brake Control Module | The control module K17 can increase and decrease the brake pressure on all 4 wheels individually in order to fulfill these functions:
The control module K17 can also influence the following control modules to limit the amount of produced torque:
