Introduction
The networking concept
Overview of networked control units
In order that data can be transferred without
conflict or interference between the individual
control units, these are connected together in
a network via various data bus systems.
The data bus diagnostic interface J533
(Gateway) provides an interface for the
following data buses:
- Drivetrain CAN data bus
- Convenience CAN data bus
- Infotainment CAN data bus
- Dash panel insert CAN data bus
- Diagnosis CAN data bus
