Parking system distance sensors
Sending signals
The parking system control unit sends the following information or requests over the chassis FlexRay:
Request to show the parking system display in the multifunction display
Request to display messages or issue a warning tone
Parking system status indication request
Request to steer
Information on distance up to obstacle (remaining distance up to obstacle in direction of travel)
