SZL: Steering column switch cluster

The steering angle sensor is integrated in the steering-column switch cluster (SZL). The steering angle sensor delivers the steering angle as a signal. The plausibility of the steering angle sensor signal is checked against the signal of the motor position sensor. If the deviation is too great, the steering power assistance is switched off with a fault entry. The EPS calculates the steering angle and steering-angle speed from the signal of the motor position sensor. The signal of the steering angle sensor is only required for initialization and the plausibility check.

The steering column switch cluster is connected via the PT-CAN.
