Schematic overview and setpoint values
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The position sensor for the swirl flaps is supplied with 5 volts and ground by the DDE.
A bridge circuit (H bridge) is used to activate the servomotor. This permits activation of the servomotor in the opposite direction. The bridge circuit is monitored diagnostically. H-bridge designates an electrical gearshift with 5 shift elements in the shape of a capital H for shifting between.
