It will also allow you to reprogram a module that you are replacing.The Tech2 communicates with the computer using a serial port on the computer running Windows XP SP3. For example, I was able to update all of the modules and PCM in my 2006 9-7x even though it had only been a year or two since production and issue of this software. It will have PCM and module updates included. It was discontinued in 2008 by GM which means that it works only for vehicles up to model year 2007. That's because only dealers have those or a clone of one wasn't included.First of all, this is old software. If you install it and try to use it, it says that it can't find the USB security dongle or something like that.
If you bought one of the Tech2 clones, it probably came with a CD with the Tis2000 software. Things like updating PCM's and modules and anything security related are locked out. And a lot doesn't apply since it's geared towards Saab (even the 9-7x doesn't apply, it's under GM).So you have a Tech2 but a lot of the things you would like to do is locked out because you don't have access to the computer software to allow you to do it. A lot of info I found over at but it is just a giant thread to read through although a lot of the info is on the first page.
