This is about GM Tech2 Scanner for Hummer troubleshooting and programming.

Can I have a cheap Tech 2 for Hummer?
Yep. Both the original and HQ clone can work for your car.

Where can I get a working clone at a good price?

Why my Hummer is not shown in the GM vehicle list?
That little short list is incorrect and only shows a few of the earlier than 2007 CAN bus vehicles.

Tech 2 clone for both troubleshooting and programming Hummer?
I’ve used my Tech2 on my 08 many times for troubleshooting not programming
But I think it should be able to program Hummer.

Anyone has good success of Hummer H3?
My H3 has had a CEL on – po452. I checked it with the tech 2. Well it pulls 3 codes, po455 (large evap leak), po442 (small evap leak), and po449 (vent solenoid control).

Tech 2 is possible to program for Hummer H2 above the year 2007… what to do in that case?

Actually it does the programming just fine on newer than 2007 GM vehicles BUT you must pay for an ACDelco TDS subscription for vehicles above 2007 and you would use the CANDI module that comes with many of the Tech2’s for working with CAN bus vehicles. You can subscribe for it.
This is ONLY needed if you want to program or update the software in a module. ALL of the build in diagnostics and testing for vehicles up to 2013 works without the subscription or the older TIS2000 software. You only need those for doing actual programming. The older TIS2000 software – that is what has the programming was discontinued in 2007. TIS2000 does have the actual programming for all vehicles up to 2007. After 2007 GM went to the TDS system.
You can also get a newer style MDI or MDI 2 for diagnostics and programming. The catch with those. They have NO screen or built in software and you must pay for a subscription from from ACDelco TDS to use an GM MDI.
Other brand units, a very select few can do actual programming and use the pass-through method. NONE have the diagnostics that the actual Tech2 scanner or MDI interface (with the subscription) will have. Check with Autel and see if they have the full diagnostics and re-calibration for the rear air suspension on a Hummer H2. Not going to happen, there is too little demand for them to hack and reverse engineer that particular bit of code in a Tech2 to figure out the diagnostics and then write programming for that for their tool.

Tip and Guide Needed before Buying Tech 2 for SPS Programming
Hi all,
Here are all experience of Chinese GM Tech 2 interface for SPS programming and hardware key issues. You will get useful tips/guide. Have fun.

Confirm your card with a brand:
Before buying, you should tell your seller: Will you choose GM or SAAB or Isuzu or Opel card?
Because every card to one brand cars. If you want to do more brands, they will ask your pay extra fee for other cards.
Hope it be useful.

Can do programming:
Chinese clone Tech II don’t have hardware key but it can do programming

TIS2000 dongle & sw make it:
The TIS2000 Dongle( the newest one is USB flash type ) and the TIS 2000 software could do the SPS programming . usually the chinese gm tech 2 kit not included it . you should point it speartly that you need it very important . may be need more $100.0 for the dongle and software

Work for cars 2008 or older:
You should use the TIS200 dongle and software for reprogramming SPS and access Immo SYSTEM but just work for 2008 year or older. for new cars, you should use the MDI module programming online

MDI instead for new cars:
buy GM MDI instead as it will run tech2win and do sps flashing and also do latest model cars that tech2 won’t do

Must have TIS2000:
the Chinese GM Tech-2 can’t program, if you want to do programming you need to buy the TIS2000 software. It has the hardware key.

Works well for one year:
if you consider to buy one, I can suggest you buy it using the site CnAutotool.com , I buy it one years ago, and it works well now, and they can supply us the technical support. I use it to program with the TIS2000 software….

Works fine for 2 years:
I bought a Chinese OPEL TECH2 interface off CnAutotool.com , from two years now and it stills working fine. If you use the right software you wont found any inconvenience …
There’s no need of drivers and Opel tech II is an Auto exec file, so it doesn’t need to install.
I Hope it’s been helpful 4U

Both 2 units work fine:
I bought 2 units from different suppliers, both work fine, until I bought the original tech2 card from one of this suppliers It does snapshots, and programming but one of the units wont accept the card, it seems like one of the edges close to the pin connector side , is been damage well one of the problems, the main problem I think is after I use explorer manager to upload the file to the tech2 card on my laptop I did it many times with no problems it work just fine, but after that day I couldn’t it goes up to 25% and gives an error related to power , couldn’t find a card of 12v or something like that, and the other card finish fine but when when I plug to the tech2 it wont recognize the card it displays downloading mode and that it, but a clone card work fine so I use this to diagnose, ifany body knows how to do a low level format or some fix like that in order to be able to use the card again please help.
Until today I’m using tech2 clone from china it does SPS and all, still working fine I have a software emulator for dongle it works great on American NAO, Brasil, Isuzu, I do SPS on all this vehicles with no problems. just make sure you get a card for SPS, snapshots and it will work.
