Signal transmission
WARNING: This page is about a different variant/trim than selected.
The steering column switching center can be connected to the following bus systems:
- Powertrain-CAN (PT-CAN) already in the basic version
- Chassis CAN (F-CAN) with dynamic stability control
- Body bus (K-Bus = sub-bus) for the cruise-control system with multifunction steering wheel
The K bus runs from the steering column switching center to the right-hand MFL button pad. The left-hand MFL button pad is connected via the right-hand MFL button pad.
The buffer spring cassette transfers electrical signals inside the steering wheel and from the steering wheel.
