Is there a protocol for GM vehicles definition document available to use in the creation of the diagnostic VI

I am considering creating applications using data available on computers cars GM todays vehicles.  Is there a basic set of lists of parameters and methods documented or that is available to make such a development?

Thank you

Hi, Hummer1.

Today, networks in the vehicle through an electronic control with the CAN (Controller Area Network) interface unit.  Each device on the network will have a CAN controller chip.  A really good tutorial to understand this interface can be found here.

There are two APIs CAN that is used with the NI-CAN driver:

  1. Frame = this is the original for the programming of the CAN API.  It provides access to the network BOX.
  2. Channel = allows to access the network in simple physical units that are easy to use.  Hereis an excellent DevZone article that explains the API NI-CAN to channel more in depth.

Let me know if you need more information.  Happy holidays!
