They don’t have to be electrical engineers or software developers, but they need to be able to do more than follow rote procedures-although, frankly, I’ve seen all too many times when step-by-step use of the Repair Manual would have been far more effective than leaping to conclusions based on incomplete or flawed systems knowledge. You’re quite correct, however, that service technicians need to know something about diagnostic systems, communications networks, and electronic control units.

Everything else, even if provided using the same data link connector (“DLC3” or “Data Link Connector 3,” in Toyota’s terms) and similar protocols, is controlled by the automakers and their suppliers, who can follow or ignore the SAE and ISO standards, as they choose. I can add Toyota support for a minimal cost but probably go the official route.Ĭlick to expand.Strictly speaking, OBD II (spelled thus by EPA, CARB, and SAE, by the way) refers only to the subset of on-board diagnostic capabilities required by emissions regulations. I also have a VXDiag Multi Diag (multi-manufacturer but the one I bought specifically PIWIS 3) system I bought from. But when I subscribed again (for $55 the old price) I could not download the new version. I did once hack the download to not expire.
In fact if you search the techinfo site you will find it the Lite version referenced there. There was/is a known bugs list on the techinfo site to see if there's something you need that the Lite version can not do, but I'd be very surprised if that list is long. When I asked the tech support the person at the time said they are working on solving that issue. It is a dealer level tool otherwise fully compatible with the software. I sent him a message about possibly selling it and he said he used it every day. I even found the old DENSO VIM on eBay but a mechanic had just bought it.
