3) Removable hardware modules provide insurance against scan tool obsolescence.
4) Large, easy-to-read backlit screen.
5) RS232 & RS485 ports provide the avenue to connect future devices to your Tech 2 Flash.
6) Ability to capture stored DTCs, Freeze Frame, and Failure Record for later review.
7) Ability to view the status of vehicle diagnostic tests as they run.
8) Bi-directional The authentic GM 1992-current year software will provide full bi-directional control when performing power train, chassis, and body diagnostics.
An industry change in protocol from OBD II to Controller Area Network (CAN) has begun. In order to perform diagnostics on a vehicle that uses the CAN interface; you will need the Tech 2 Flash and a CAN diagnostic interface module. The module connects between the Tech 2 Flashs diagnostic link cable and the OBD adapter. Once the module is connected, it can be used on all GM vehicle applications,even those vehicles using other platforms such as OBD I and OBD II.

Q: Can GM Tech2 read VIN?
A: Yes, it can do.
Q: Does gm tech2 do Hummer H3?
A: Yes, it does. GM Tech2 can do diagnose for Hummer h3 model.
Q: Can gm tech2 do airbag resetting for Chev Tahoe 2007?
A: Yes, it can do airbag reset for this model.
Q: Does gm tech2 support Saturn?
A: No, it doen't.
Q: Does gm tech2 work 2007 Cadillac Escalade?
A: The software car list includes the Cadillac model.
A: If the TIS2000 you are trying to install is contained in the GM TECH2 software, then it is useless to install TIS2000 software. To program electronic control unit, I advice you buy an extra TIS2000 to work with GM tech2.
Q: After receiving GM TECH2, I got some errors.
A: If it is Blue screen, just replace the Blue Screen Chip. If it is not the problem of Blue screen, please send us the self-test report to check where the problem is;
have no idea on how to operate self test? Refer the self-test manual at GM TECH2 "technical support / service".
Q: GM TECH2 one button doesn't work how to fix?
A: If you have new version GM tech2, there are two ways to solve:
1) we send you a new button to replace;
2) please send back to repair.
If you have old version GM tech2 installed with the newest software, the button maybe won't work.
Q: When I use GM TECH2 for the second times, the tool starts to smoke, and my car voltage become 14V from 12V, what's the matter?
A: Please follow the correct operation steps: before diagnosing, turn on the ignition and then connect the GM TECH2 with the car, when the car starts you'd better test the voltage, because during this process a part of cars'voltage will reach up to 24V or more, especially the car which has a poor contact of electrical ground.
GM Tech2 clone scanner is tested ok to program out GM Corvette F45.
Where to have one GM Tech2?
Google Search is your friend !
I bought mine from the same place. Had it in less than a week.
Took a picture of Tech2, pretty high quality of CANDI unit, cables, along with one of the 12 volt adapters. And the data disks .. as you can see the labels were not made with an INK JET printer …
This is how to fix Tech2 Tech2Win license information “expired or not exist”, including how to send licence to Tech2win from GlobalTIS
The error message and the screenshot:
Tech2Win license information
E667481: Your license has expired or does not exist!
Please perform a software download or a security access to refresh your license.
Meanwhile vehicle communication and CANdi detection is disabled.
Which cable you using? Probably with PassThru.
You must send permission (licence) from GlobalTIS to Tech2Win.
Digit after the lock (bottom part screen) show you how many days you have licence to use. If you using GlobalTIS v28-32 licence will be for 1 day (24hr), after expired licence you must send again.
Instruction: how to send licence to Tech2win from GlobalTIS:
(the example from AVDI)
In GlobalTIS click on Security Access (Security).
In GlobalTIS, Security click on the button Start Download. This will run Security Access wizard.
When its main window is displayed click on the button Next.
When the activation finish you will see the following window with information: “Security Access Enabled Security Access type 3”
After a successful security access inTech2Win you can see an open lock on the right side of thestatus bar. Inside the bracket you see the number of days the license is valid.
When you startTech2Win again the security indicator is not displayed as long as no vehicle communication isbeing performed.
During the first communication with a vehicle the license will be checked and theindicator displays either an open or closed lock.

Hope this helps
I just checked my Tech II clone against my 2006 C6. In the ABS section there is an “Automated Bleed” option. In the Radio section there is a “VIN Relearn” option. I’ve never actually used either one, but I bet they work.
The clones are literally running the same software as the Tech II, so they have all the same functions. There are a few caveats: the standard clone power supply will cause the unit to reset if you run the starter motor, apparently, though this can be fixed. Also, operating while tethered to a PC involves a bunch of licensing hacks and other nonsense. But you only need to do that if you want to flash the ECU firmware.
The Tech II lets you see (and individually reset) all the DTCs from all the modules. It also has a bunch of special functions and bidirectional capabilities.
It’s great as a standalone diagnostics tool but it isn’t intended to modify ECU parameters like tuning software does. This is a tool for fixing the car, not modifying it.
This was my order of GM Tech2 Diagnostic Scanner with TIS2000 Software:
Order Date: Aug 26, 2018
Ship to: United States
This is how GM Tech2 looks out of the box:
The following 3 paragraphs are what I mail to OBD2eShop:
I tested device and it works well. Problem is the screen. I believe for return I would have to send back and pay for shipping. This would take a long time and I have work to do using the tool.
Right now I am using a laptop connected so I can see the full screen
Finally, OBD2eShop ship me a new package.
Just want to let you know, I finally took the time to really test out the replacement I was sent and it appears to work perfectly.
One small issue is that I was sent a GM PC Card and not a Saab one. I tried to write the GM Card in my laptop to Saab software but I ended up damaging the card. It was my fault. I know that I could have contacted you for help and you would have taken care of me.
I was able to find another Saab Card and get it working so I am very happy now. I do not need any more help.
Thank you so much for your above and beyond service. I think very highly of your store.
(hhhhhhh,OBD2Eshop also thanks for your credit)
Here is the new package OBD2eShop ship to me:
Problem: I have a tech II with Saab v148.o card in it. I have tried from Globaltis(Cracked) and TIS 2000 (Hardware key) but cannot gain security access.
Tis2000 gives me the error “cannot connect with security server”
Globaltis just says “error” when trying to gain security access.
I know it is communicating with the tech ii, because during the security check the tech goes from the home screen to “downloading”.
I am using a laptop with a TRENDnet TU-S9 USB to Serial Converter running XP SP3. I have java version 6 update 12 running.
The only think I’ve noticed is the when starting globaltis it states “SAAB Automobile AB v146.00”. I have the 148 SAAB PCIAM card, do not know if that could be affecting it or not.
Customer solution from mhhauto forum:
Here in the forum two types of SAAB v148.000 PCMCIA was shared
One for Tech2 hand held and one cracked for Tech2 Win
In Tech2 hand he’ll only the one for its working
If its the right card uploaded in your tool card then go Security and do it
Try Java v 6.26
Its the best for GlobalTis or Java v7.0
Do you have it or not installed the SAAB v148.000 PCMCIA installed and can you connect to your SAAB car?
If not you can find this PCMCIA SAAB v148.000 for Tech2 hand held in the forum ( Not the one for Tech2win ) and use Card writer to flash you PCMCIA or MCE software
use the advise of Mr. techamp (try to re-flash your Tech 2 PCIMA card with Globaltis so your hardware and software match. i believe version on globaltis is 146.00.) and use the SAAB GlobalTis to write your PCMCIA card
Then go to your card and check if the diagnostic is possible
Then connect again the Tech2 with the computer ->power it up ->run the GlobalTis-> use Security
Then you can do any SPS Programming in your car
Tech II clone not boot up (not turn on)
The issue usually results from the DC to DC converter
This converter is a common internal component for the device GM TECH II
originally these come equipped with the “Meanwell SKE10A-05VT” and “BTCPower 4BE-01T-02”
you cannot longer purchase these items because they are not being manufactured anymore
You actually can find the “Meanwell SKE10A-05” but missing the “VT” and also missing 1 pin for the soldering points.
BEWARE this model dc to dc converter WILL NOT WORK
It may help you power on your device, but the power button among other programming features won’t work.
– Solution worked!
To replace DC to DC converter can avoid unpleasant surprises.
REC10-1205S/H2/M has a 6 pin connections, “Meanwell SKE10A-05VT” and “BTCPower 4BE-01T-02” have a 5 pin connections, is it not a problem when you change the component.
So, sort this out.
This list is for a DC to DC converter with the following specifications:
Output: 5VDC 2.0A
– GM Tech 2 PCB before the DC to DC converter replacement
– Tech2 clone worked gain after the DC to DC converter replacement
– The important note: Tech2 not boot up when the car starts
So, how to fix a reboot Tech 2 when starting the car? The square dedicated native voltage Stabilizer, black spots, this is how it is better to feed on, immediately giving to drink block, then the main Board gently giving to drink lagged behind in her legs. By means of wooden toothpicks carefully remove the solder prepared under us new voltage regulator (mornsun VRB1205LD-15W DIP).
