Steering Wheel Rotation Sensor

The steering wheel rotation sensor measures the rate of rotation of the steering wheel by monitoring the steering wheel rotation ring as it passes through the sensor gap. The steering wheel rotation sensor uses 2 signal lines to transmit information to the stability assist module: whether the steering wheel is being turned left or right and how far it is being turned. The stability assist system compares the steering wheel position to other input signals and stores them to determine a relative straight-ahead position. Stability assist confirms this position and modifies it as necessary during every new driving cycle.
