GM Tech2 is the same tester GM Technicians use to diagnose GM vehicles. The Vetronix Tech 2 comes with Authentic GM software and provides support for on-board diagnostics on all GM systems. With TIS2000, you can do programming for GM cars till year 2007. Tech2 Diagnostic Tool Highlights:
1.Support Car Models : GM/SAAB/OPEL/SUZUKI/ISUZU/Holden,while programming for GM cars till 2007.
2.Performs Functions such as Capture stored DTCs, Freeze Frame, and Failure Record for later review,etc.
3.It comes with CAN diagnostic interface module with which you can work on vehicles under OBD ,OBDII and CAN protocol.
4.The Tech 2 includes the the software which is put in the 32MB card.Each card contains one model,you can buy individually if want more.
GM MDI VS Tech2 in car coverage, function,performance
Since 2006, rumor has it that GM Tech2 scan tool will be replaced by GM MDI (Multiple Diagnostic Interface), a new piece of equipment coming out to work alongside the Tech 2, but today we still can find Tech 2 in GM forums, where drivers are hesitate between MDI and Tech2. Here I will analyze the difference between the two tools and reveal the reason why Tech2 is not be replaced.
Vehicle Coverage
GM Tech 2 is used on obd2 GM vehicles which mainly built from 1992 to 2011, while GM MDI supports vehicles from 1990 up to 2013. Now every vehicle for now on will be using GDS with the MDI that is why we said MDI is replacing the tech 2. However, Tech2 works with quite well with some SAAB cars due to its SAAB card, while a few SAAB owners said MDI not support their cars.
Function
MDI is a diagnostic and programming device. Apart from diagnosing 1990 to 2013 GM, Opel, Chevrolet and Saab, it also supports TIS2Web, GM Global Diagnostics System (GDS), SPS and MDI Manager Software, European Chevrolet offline programming, SPS programming on existing and future SGM vehicles, and will be able to do remote programming with the Tech 2 for all 2007 and previous vehicles in the near future. Using the GM MDI for programming can free up your Tech 2 for diagnostics and other tasks.
GM Tech 2 mainly supports diagnosing; with TIS 2000 CD in the package, it can also do programming. But it cannot program as many systems as GDI.
Communication
MDI works with a PC. It takes advantage of all those new PCs installed in the service bays under the Multiple PC Initiative and is able to communicate with a laptop via both USB and WiFi so that users can put MDI in a vehicle in the parking lot and communicate with it my PC.
Tech2 is a hand held device and communicates vehicles via USB cable, no additional PC is needed. It is very easy to carry and use.
Performance
The GM MDI offers faster programming speed at a lower cost. Depending on vehicle architecture (protocols/modules), the GM MDI from Obd2tool.com can be 20-70% faster than the Tech 2. This helps alleviate vehicle battery drain problems during programming.
