CAN Networking Concept

Networked Control Modules

To allow the new Jetta's control modules to
communicate, they are connected by
various data bus systems.
The Data Bus On Board Diagnostic
Interface J533 provides access to the
following data bus systems:
• Drivetrain CAN-bus
• Convenience CAN-bus
• Infotainment CAN-bus
• Instrument cluster CAN-bus
• Diagnosis CAN-bus
In addition to the CAN-bus, a
number of electric components
are networked via the LIN data
bus.
Refer to SSP 873403, "The new
Jetta Electrical System Design
and Function" for detailed
information on CAN-bus
communications.
