This becomes critical when transmission and engine control modules must chat with each other to control the powertrain. The CAN network is a standard high speed communication protocol that is used on most vehicles sold in USA and allows devices ‘on the data bus’ to communicate at speeds of 500 kilobits per second. Ultimately, all of powertrain components such as the engine and electronically shifted transaxle terminate on pins 6 and 14 of the DLC on what is a high speed or Controller Area Network (CAN). GM TECH 2 LAPTOP SOFTWARE VERIFICATIONThose of you who live in the USA that do state mandated emission testing may find that they now just plug into your vehicle for verification of the vehicles emission compliance. This connector allows any OBD II compatible scan tool to ‘talk’ to the vehicle. This is where the scan tool plugs in and becomes part of the data network. Here in the United States all vehicles communicate via a standardized or OBD II style data link connector, so if you crawl under the dash of your 1996 and up Saab you should find the connector. My 2007 9-3 Aero has the turbocharged V6 and six speed automatic, so that is what will be referenced here. All I needed was my Saab to give the Tech II something to do. GM kindly supplies our school with all this hardware. If you really want to know what your Saab is thinking about when you’re motoring around town this holiday season, hopefully Santa will have dropped the following pieces of hardware off for you:Ī CANdi module so the Tech II can talk to the high speed network on your SaabĪnd of course the Saab software program for the Tech II ![]() Hopefully this will be the first of a few articles on this. ![]() I’d like to thank Ted for taking the time and giving us this insight into the little electronic doodads that control our Saab vehicles. Tedjs, our resident tech guy, has kindly provided this insight into the modern mechanic’s Swiss Army Knife – GM’s Tech 2 (or Tech II as you’d write it if search engines didn’t exist.) ![]()
