Re: OBD2 Communication Question
Found this is my notes:
"Controller Area Network (CAN) electrical systems began to appear in new vehicles in 2003. Since then, more and more vehicles have been equipped with CAN systems, until 2008 when virtually all passenger cars and light trucks sold in the U.S. were CAN-equipped.
As a vehicle owner or do-it-yourself mechanic, you need to know how CAN has made the electrical system in late model cars and trucks much more complicated than ever before. CAN allows various modules and systems to share data and interact in ways that where previously impossible.
So what exactly is CAN? It is a communication standard that allows the various modules and computers in a vehicle to talk to one another via a common "data bus" circuit in the wiring system. Think of it as a high speed party line that allows data and commands to zip back and forth from one module to another. This allows the Powertrain Control Module (PCM), antilock brake/traction control/stability control system, electronic steering, electronic suspension, automatic climate control system, keyless entry system, lighting control modules and dozens of other systems and modules to all be interconnected electronically."
Hope this clarifies it for you.
