Information on the Traction Control or ABS System

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Control unit

The ABS sensor system or traction control system prevents wheel lockup during braking, allowing the vehicle to maintain stability during braking even in the most adverse conditions. ABS sensors are located in both front wheels, and one sensor is situated near the rear axle. The sensor consists of two parts: a rotor and a stator. The rotor is on the rotating part and resembles a gear, while the stator is an electromagnetic coil with a magnet. When the wheel turns, the sensor generates electrical pulses, the number of which indicates the rotation speed.
