Steering column switch cluster

The steering column switch cluster features one steering column switch each on the left and right sides. The right-hand steering column switch is designed for operating the functions of the wash/wipe system. The steering column switch on the left side of the steering column controls the high-beam headlight and turn indicators as well as operation of the on-board computer.

The signals are made available by the steering column switch cluster via the LIN bus.

To control the LED headlights, the steering column switch cluster transmits the following requests to the front electronic module (FEM):
