Theory Of Operation
WARNING: This page is about a different car, the 2025 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
The Anti-Lock Brake System (ABS) Module receives signals from the Wheel Speed Sensors (WSS) of all four wheels. The wheel speed sensors convert the wheel speed into a signal, sent to the ABS Module. A magnetic wheel (encoder) that is internal to the wheel bearing is used to trigger the measuring mechanism for each wheel. Each wheel has a wheel speed sensor and an encoder. There is no adjustment between the wheel speed sensor and the encoder.
