The OBDII specification is in the HS3000 published by SAE. One thing to keep in mind is that this document is only a very small part of what scan tool manufactures put into their scan tools. Each manufacturer has there one proprietary codes which are not in this document and can only be obtained from each manufacturer. IP: Logged |

Hi all, I was searching today to find out the OBD-II spec, the goal is to program a user interface in VB.net and show all the various entries. What I cant find is the way to interface up to the OBD-II and decode the protocol. When I saw B&B linked here? cool, they are awesome, so is there some physical layer device, something that is either a parallel port, or USB, and either has inputs for the OBD-II physical that I would wire up to or ? If I could just get the data stream into the computer, I could make the user interface and display all the data. The SAE book costing $100+ probably wont happen, Ill find it in a library or try to skip it, years ago I had found the protocol somehow to the OBD2 but its long gone. I have some Intel 80C196 with the CAN protocol, but dont want to have to layout a pc board and write up an OS from scratch. What Id like to find is some B&B serial gadget, a streaming kernel device driver and source code extensions that work with dotnet, and details on the protocol stream so I can put them into a display/UI.

Hi Brad Did you have any luck in obtaining the spec? - I'm thinking of a decoder using a PIC chip and in car LCD display (lots of bit bashing!). Regards
