Steering angle sensor
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The steering angle sensor is installed in the steering column switch cluster (SZL). The steering angle sensor measures the steering wheel angle optically and without contact. The steering angle sensor is fitted on the printed circuit board with the evaluation electronics. The steering angle sensor consists of the following components: encoded disc and optical sensor. The encoded disc is connected to the steering wheel via the coil spring cassette. When the steering wheel is moved, the encoded disc moves within the optical sensor. There are various line patterns for evaluation on the encoded disc.
