iLink400 GM reviews:
- control all the sensors and lights on the vehicle
- Used Vident iLink400 to perform an automated brake bleed on GM and exhaust system diagnostic. Creating an account and product registration are a chore.
- replaced my Throttle Body in a 2011 GMC Sierra and had gone through the entire relearn process with no success. Drove for days with extremely high idle and acceleration issues. Finally took a gamble and ordered Vident iLink400, hooked it up and it was fixed in 2 seconds.

The Tech 2 will allow your shop to be to ‘dealer level’ capable on all covered GM cars. Scan, pull codes, graph data and have all bi-directional controls available for all vehicle systems including Powertrain, Body, Chassis and Network.
- The Vetronix Tech 2 comes with Authentic GM software and provides support for on-board diagnostics on all GM systems 1992 thru 2013.
- TIS2000 do till 2007 year GM car programming.
- Support Car Models: GM, SAAB, Opel, Suzuki, Isuzu, Holden
From 1992 to 2009 and certain newer vehicles, GM vehicles use the Tech 2 handheld scan tool. It is the same scan tool as is used also for GM, Saab, Izusu, Suzuki and Saturn including the Saturn Astra (Opel import).
The Tech 2 scan tool simply uses different 32 MB software cards which are removable and switchable. It is a very versatile tool. Extra memory cards cost an average of $400 for the dealership sw or $10 around for a decent clone program, which allows us to expand our diagnostic capabilities really inexpensively. The Tech 2 is menu-driven and user-friendly.
The Tech 2 scan tool is also used for reflashing GM vehicles. It uses a serial adapter with a network cable to connect the tech 2 to your laptop.
NOTE: A serial adapter is used on the laptops 9 pin serial port. Do not try to connect the tech 2 directly to your laptop with just a network cable, because it won’t work. GM has certified a specific brand serial to usb adapter for use on all modern laptops without a serial port. We do stock this part, with the cost being $59.95 plus shipping.
In 2004, GM began phasing in to CAN system cars and a CAN adapter was built so the Tech 2 could access them. GM called it a CANDI (Controller Area Network Diagnostic Interface) module.
If you are interested in having full diagnostic capability on GM vehicles 2009 and older, this is it. No compromises, and no expensive required subscription every year just to use it for diagnostics. You can count on the reliability of your diagnostic information 99.9% of the time when using a genuine Tech 2.
There are many Chinese manufacturers producing Tech 2. But this one is the best quality and well-received:
In 2010, GM started phasing out the Tech 2 in favor of a laptop-based system called GDS2. Six vehicles in 2010 are not Tech 2 capable anymore, with more being added to the list as the years go on.
The six vehicles are:
Chevrolet Volt gas/electric hybrid
Cadillac SRX SUV
However, as of 2013, there are still GM vehicles that require a Tech 2 scan tool, especially the trucks.
GM Tech2 Clone Diagnostic Scanner Feedback:
In 2010, GM made a change in their vehicles, moving to a global platform to simplify marketing their vehicles all around the world. The communication systems changed, and the Tech 2 scan tool was no longer able to access them.
In preparation for this change, GM years later released a laptop-based Multiple Diagnostic Interface or MDI – the blue box.
Now it is superseded by the MDI 2. It was only used for reflashing, but the dealers loved it because it was twice as fast due to its USB connection to the laptop. (The Tech 2 is a serial connection system and slower to transfer data for reflashing.)
GM then introduced the GDS1 (Global Diagnostic System version 1) scan tool to run on a laptop. The new GDS2 is simply a newer and better version.
GDS2 requires renewing of the license to use it by visiting the TIS2Web site at least once a month (if you have a yearly subscription). TIS2Web is GM’s website to download the scan tool or reflash data to update a vehicle’s computer.
You download vehicle software to your laptop and then you run the vehicle choice or program to scan from your laptop with the MDI 2 as the interface between your laptop and the vehicle. You don’t HAVE to be online to use GDS2, only download the latest software license to use it by visiting TIS2Web monthly.
When you start GDS2, the bottom of the screen shows how many days left till an update is required. If expired, simply log in to TIS2Web before you work on a GDS2 vehicle, and renew your license then.
Also, you can get GDS2 crack without expiration issues:
The license requirements don’t apply with a 2 day paid pass to use GDS2.
GM also came out with a software program called Tech2Win (Tech 2 for Windows). This is a Tech 2 emulator that runs on your laptop and simulates the Tech 2 screen and keypad to operate it.
Unfortunately, it leaves something to be desired with limited functions and some lack of actuator tests and incomplete coverage. It doesn’t replace a Tech 2 and is a yearly subscription purchase, but it is cheaper. Tech2Win also cannot be used for Saab or Isuzu or Suzuki!
