The teck 2 scanner is able to check all GM before 2009

I  just did a “Fast-Learn” on a G8’s 6L80E last week with mine. A Snap-On MODUS was not able to do this. There are simply factory diagnostic procedures that a T2 can do on GM vehicles that no other tool can. But yes, to reflash PCM’s, TCM’s, etc, you need to have authorization from the Tech Center, which means you have to be a dealership or a paying subscriber to the service which is a serious chunk of $$$$.

With that said, Bosch (who now owns the rights to GM Tech 2‘s as they purchased out Vetronix), will not support the unit because it’s a factory knock-off. So should you have to replace the VCI module (I’ve had to replace mine due to wear and tear on the connection where it damaged the motherboard inside), or any other necessary repair.

Also, T2’s can only be updated through 2009 MY vehicle info, was my understanding from GM. For 2009+ GM has gone to a new setup called MDI. GM MDI is backwards compatible with pre-2009 GM vehicles (it even has the software on the screen to emulate the screens you’d see on the T2).

So is this teck 2 scanner able to check all GM before 2009 obd2 with out extra software? Also wonder if it can check the cam/ distributor retard timing on vortex 350

I think the GM MDI system will go back to 2009, but the Tech2 seems to work as far as its updated. Obviously I don’t have any 2012-2013 vehicles to try it on though.

It will work on any Car Diagnostic Tool GM OBD2, meaning 1996+.

Here you can see its updated to 2013.
