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.

The GM Tech 2 tool has more powerful and functions

Have you ever search for GM diagnostic tools? And which kinds of auto diagnostic tool is special for your GM vehicles? Here OBD2TOOL will share you two kinds of professional GM diagnostic tools for your reference.

The original GM Tech2 was made by Hewlett Packard and used Vetronix software.  Vetronix purchased the Tech 2 manufacturing rights from HP.  In 2003, Vetronix was acquired by ETAS, a supplier of standardized development and diagnostic tools for electronic control units. In 2006, the Vetronix Aftermarket division merged with Bosch Automotive Aftermarket, responsible for supply, sales and logistics of automotive parts for service of the vehicle.  So today the Tech 2 is ‘made’ by Bosch.

The tech2 and CANDI module worked perfect to diagnose my bad HVAC air door actuator. I have an older HP laptop running win7 and it has a serial port so has no problem to install software. Time will tell how this works out.

the GM Tech 2 tool has more powerful and functions. Authentic software for GM in the Tech 2 Flash means the most comprehensive diagnostic software available for latest model vehicles for GM. And the removable hardware modules provide insurance against scan tool obsolescence.

The GM Tech 2 tool is ability to view the status of vehicle diagnostic tests as they run and to capture stored Freeze Frame and Failure Record for Tech 2 Flash . In addition , The authentic GM 1992-current year software will provide full bi-directional control when performing power train, chassis, and body diagnostics.
