Most vehicles on the road today communicate through the CAN (Controller Area Network) Bus interface.  GM has its own version, the LAN system.  If you do not completely understand CAN data and the GM LAN system, you should learn today.  AVI and Dave Hobbs CAN guide you through the functions, features and diagnostics of the CAN system.

Video Clip:

Dave will start with an explanation of CAN data, how it works and why it is necessary.  He will show you how to identify vehicles that are equipped with CAN and how the system differs from others.  Dave provides schematics to help you learn how the system works.

This program explains functional diagnostics and defines buzzwords such as "Virtual Networks," "Learned Nodes" and "Buddy Systems."  Dave defines code suffixes and system numbers and shows you how they can help with diagnostics.  He also explains what a "CANDI" (Controller Area Network Diagnostic Interface) module is used for.  Dave packs a huge amount of information into this 1.25 hour seminar.
