Signal transmission

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.
