Self Study Program 873403 – The new Jetta Electrical System

VAG SSP 873403. This Self-Study Program covers the new Jetta’s electrical system. This program also describes the new control modules, the networking of various body electrical systems, and the various CAN-bus systems.

The new Jetta makes extensive use of control modules and networking using multiple Controller Area Network (CAN) buses. Signals are transmitted digitally from one control module to another on each CAN-bus, eliminating the need for a separate wire for each signal. The use of CAN-bus communication for controls and accessories reduces the wires needed in the vehicle.
