Brief component description
The SZL (steering column switch cluster) consists of the following components:
- Evaluation electronics The signals of the components are evaluated in the evaluation electronics and output as a CAN message via the F-CAN. The evaluation electronics is installed on a board.
- Evaluation electronics The signals of the components are evaluated in the evaluation electronics and output as a CAN message via the F-CAN. The evaluation electronics is installed on a board.
- Steering column lever Lever positions of all steering column levers are determined optically.Pressing the buttons and turning or touching the knurled wheels are sensed via switch mats.
- Coil spring cassette. The coil spring cassette has the task of transferring electrical signals from or to the steering wheel.

The SZL (steering column switch cluster) has no fault memory of its own. All the fault data of the SZL is stored in the DSC control unit.
