Tech 2 doesn't program for H2 above 2007?

"Dear All,
Please advise:
- what do you think of Tech 2 made in china?
- Is there any software close to Tech 2 to be bought which has access to all hummer h2 modules?
Regards, YF"
I bought my Tech2 from chinacardiags.com and it works great. Cannot really compare software with a Tech2 as that is comparing hardware to a program. That being said, there is a software side of things that work alongside the Tech2 which is the TIS2000 software. Getting that working is a bit of a project in and of itself as the software is old and seems to work best on Windows XP. The TIS2000 software is really not needed to use the Tech2 though - that is needed if you want to update the firmware in the various modules in your vehicle like the ECU, BCM, DDM, etc.
(Tech2:http://www.chinacardiags.com/wholesale/tech2-diagnostic-scanner-for-gm-saab-opel-suzuki-isuzu-holden-with-full-package.html)
Simply put though. There is no other tool that can do everything on your H2 that the Tech2 can do. It is the only tool with things that are very specific like calibrating the rear air suspension module. Other tools can be very powerful but that are mostly just have features that are common to many vehicles and will not have things that are specific to just one or two vehicles.

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 as little as two days for $55.
https://www.acdelcotds.com/acdelco/action/subscribehome
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 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 or MDI (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.
For programming you also need to have TIS2000 running on a computer or pay GM for a 24 month subscription for their TIS2WEB (Vehicle Programming) for $40 https://www.acdelcotds.com/acdelco/action/subscribehome
The computer will need a serial port for downloading the programming to the Tech2 for programming your vehicle.
The way programming works is you connect the Tech2 to the vehicle and tell it you want to program a module. It interrogates all of the modules on the vehicle for the current versions and the VIN number. You then connect it to the computer running TIS2000, GlobalTIS, or TIS2WEB subscription and select programming in the computer. It reads the Tech2 for the vehicle info and then presents you with a list of software for all of the modules and shows you which have updated software. I recommend only doing one module at a time which is a good bit more back and forth but safer. The computer then loads the update to the Tech2. You take that back to the vehicle and connect it and it then programs the module.
The best, most reliable and safest method is to use a long enough serial cable (its uses 9 pin serial adapters with an ethernet cable to make the cable longer - so you can just use a longer network cable) and do pass-through programming. In that method the process is the same but you leave the Tech2 connected to both the computer and the vehicle at the same time. Once you select programming on the Tech2 then go to the computer and you can immediately update each module right from the computer.
There is a slightly more updated version of standalone TIS2000 floating around on the web which has additional updates that has software updates for vehicles through 2009 as well. I know just using that TIS2000 both my GMC truck and my 2003 H2 both had a bunch of software updates available to be programmed all of which fix small issues or improve certain aspects. One example in on the older single compressor air ride like my 2003. Those would run and make small adjustments a LOT more often than needed and the software update fixed that. On the H2 the rear air ride is also one to be very careful of for doing software updates though. For example, my 2003 came with the earlier style single compressor but if it were to fail a dealership would replace it with the newer style dual pump compressor. Programming would still think its the original style and would attempt to program it and that would actually cause it to fail. TIS2000, (Global, Web, etc) will warn you about this sort of thing though so just heed all warnings and follow instructions and its fine.
The programming aspect is not needed or required to use the Tech2. The Tech2 still gives you a TON of diagnostics and tests that NO other OBD device has including things like the air ride module, detailed BCM functions, basically you can control and test every computer module in the vehicle.

Tech2 vs Tech2win - Read before buying a Tech2 clone

It is very difficult here to find a mechanic that can interface with every function (diagnostic, coding, programming) and most don't know anything about the quirks and troubleshooting methods of these cars. Thats all good, all part of the fun of owning these cars out here they are very rare.
That leaves me with three options:
1) Tech2 clone - These use old hardware and GM have discontinued them although chinese companies seem to still be manufacturing them presumably because there is still a demand for them. There are mixed reviews on the internet but as a general rule it will work for what I need but maybe prone to failure. They will not interface with newer GM vehicles around 2010 plus? (might be slightly off on that year so don't quote me)
2) MDI clone - GM's diagnostic tool for dealerships is the MDI2. These are very expensive but can interface with every GM vehicle. The catch is that the software is done online and very expensive (around 2k per year for the comprehensive options or you can get a 3 day pass for around 50 bucks) The MDI was later replaced by the MDI2.
The chinese have copied the hardware for the MDI but not the MDI2. This probably doesn't matter for me. You can then obtain cracked versions of tech2win and GDS2 on the internet and use your clone MDI in order to interface with every tech2 function using the tech2win cracked version obtainable on the internet or in some cases included with the hardware. These are still somewhat expensive however theoretically more reliable and easier to transport provided you don't mind using a laptop. They are also much faster to transfer data when programming or retrieving data.
3) VXdiag Vcx NANO - This is basically a knock off MDI in a different case with a fake driver to 'trick' the GM applications (GDS2, Tech2win, TIS2000) into thinking its an MDI. These are very cheap and can be obtained for around $100. I have purchased one which includes the cracked versions of above programs.
Using the VXdiag NANO and tech2win application, I have been able to access every tech2 function including completing a CPS variation relearn, access all abs and airbag troubleshooting functions on my '99 C5 corvette. I have also been able to access ServiceProgramming System functions using TIS2000 and the vxdiag nano to update the PCM. This is very promising because of the price in comparison to a tech2 clone.
The catch? I don't think it will work on all GM vehicles. When attempting to interface with my '97 camaro, I was unable to access the ABS or airbag functions of the tech2, receiving a communications error. I guess my camaro is still old enough where the abs and airbag functions are performed over the OBD1 data bus (although it has an obd2 connector). However, I was able to carry out programming using the tis2000 application and access transmission and drivetrain functions.
If you are in the market for a tech2 for your C5 corvette, I think you should not purchase a tech2 clone. Instead, go for the MDI clone, or maybe the vxdiag nano if you are willing to risk the fact it seems to be hit or miss depending on the vehicle(s) you plan to interface with.
I have just purchased an MDI clone so will be interesting to see weather that will allow me to interface with the abs and airbagfunctions on my 97 f-body. If this also fails, I will have to purchase a tech2 clone.
One other thing to note, if you are intending to do programming, the TIS2000 application has not been updated by GM since 2008. Instead, they now use an alternative online based application called 'tis2web'. While TIS2web has been cracked for the european export GM vehicles, it has not yet been cracked for north american operation GM vehicles. As a result, if you are using a newer vehicle for programming, you will really need to purchase a 3 day subscription to tis2web.

Why do you need both GDS2 and Tech2Win for GM MDI?

Because GDS2 works for the new GM MY2010 only while Tech2Win works for the old.

Vehicle CoverageWorking for new GM motors 2010-Working for old GM motors
Part 1: GDS2
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, years earlier, GM had released a laptop based Multiple Diagnostic Interface or MDI . The blue box.
Note that the MDI 2 is used for reflashing only but the dealers loved it because it is twice as fast because of its USB connection to the laptop. (The Tech 2 is a Serial connection system and slower to transfer data for reflashing)
Back to the MDI. Global cars like the 2010 :
Chevrolet Camaro
Chevrolet Volt gas/electric hybrid
Buick Lacrosse
Cadillac SRX SUV
GMC Terrain
Chevrolet Equniox
We are now onto GDS2 which is simply a newer and better version than GDS1.
GDS2 requires renewing of the license to use it by visiting the Tis To WEB website at least once a month (if you have a yearly subscription).
Tis To Web as it is called is GM's website to download the scan tool or reflash data to update a vehicles 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 do not HAVE to be 'online' to use GDS2, only download the latest software license to use it by visiting Tis To Web 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 Tis to Web before you work on a GDS2 vehicle and renew your license then.
The above license requirements don't apply with a 2 day paid pass to use GDS2.
Part 2: Tech2win
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 does not replace a Tech 2 and is a yearly subscription purchase but it is cheaper.
  Tech2Win also cannot be used for Saab or Izusu or Suzuki! 
GM really needs a laptop with a Intel I5 quad processor and 4 GIG of RAM plus Windows 7 Professional.
I recommend a refurbished Panasonic Toughbook CF19 tablet with 2.5 GHZ I5 quad processor with 4 partitions. You can use 1 terabyte solid state hard drives for speed and durability.
1 year warranty though you will probably never have a problem with one of these since they
are solid as a rock. If something were to go wrong after the warranty, I can get it repaired very cheaply. No sweat.
Keep GM by itself to prevent software conflicts and still get use of other operating systems to maximize laptop use with other software programs like Ford, Mazda etc.
When you first start up, the laptop pauses and offers you a screen with the 4 Windows operating systems. Pick which one you want and you are on your way. I also label them to make it more clear what is being chosen.
Example :
Windows 7 GM MDI 2
Windows 7
Windows 7

It's easy to name them anything you want.

GM Diagnostic & Programming: Tech 2 vs MDI vs Snap On Solus

This is software and equipment to get on with GM cars (2003 Monte Carlo SS, and a 2009 Cadillac STS) for diagnostics and programming.
In order to perform "advanced functions" on GM Vehicles you are going to need something that talks with all the computers on the GM Vehicle.
The ones that I know of that do this are:
1) GM Tech 2 (will handle everything including programming the computers "updating calibrations") This tool is being phased out but it's still supported until they can get the MDI fully operational. Either way this works Stand Alone without a Laptop/PC.
2) GM MDI (Some say there are limitations with some model years but others say it's better since the updates) Of course using Tech2Win to mimic what the GM Tech 2 does) - This performs like a J2534 Programmer as a Pass Thru Device. DrewTech and companies like Ease Diagnostics make J2534 Pass Thru Devices that will do this as well. And they sell their own flavor of Diagnostics Scan Software. Keep in mind only the GM stuff will do EVERYTHING for GM Vehicles.
3) Snap On Solus (This will do a lot not only on GM Vehicles but others as well. And it can do some of the advanced functions like Automated Brake Bleed on the ABS unit just like the GM Tech 2 and GM MDI) - Keep in mind there are many functions that the Snap On won't do. The Tech 2 and MDI will allows you the option to access and control everything on GM Vehicles.
There are others but I haven't seen them nor tested them.
I started out with the Ease Diagnostics J2534 Programmer with the Programming Assistant software and Scan Diagnostics Software.
However I found for programming these devices work great and they are also a good scan tool. However when I needed to Bleed the ABS Pumps on both a Silverado Duramax Dually and a Tahoe I could actuate the Solenoids and the Motor but never was able to activate the GM Automated Brake Bleeding Procedure. You can search this on YouTube to see how it works.
Ultimately I ended up acquiring a GM Tech 2 to go along with my Ease Diagnostics setup.
If you purchase Scanners that are less featured and don't support Bi-Directional diagnostics you probably will only be able to communicate with the ECU only. In some cases mid-level scanners have access to the ABS system and sometimes also the SRS system (airbag) but won't allow you to talk with the computers like the BCM (Body Control Module).
Depending on your GM Vehicle it can have as little as 3 computers and up (my wife's Escalade has 8 computers).
Also you have to keep in mind that some of the Newer Vehicles us CAN Communication. In the case of the Tech 2 you have to also have a GM CanDi Module in order to talk withe CAN Bus cars.
I don't believe the GM Vehicles you mentioned have the CAN Bus but you can look that up.
If you decide to go with the Tech 2 it can get confusing especially if you are wanting one that isn't a Chinese Clone.
The Tech 2 has been manufactured by Hewlett-Packard, Vetronix and Bosch/OTC. Regardless of which one you get they should do the job the same.
If you want official updates from GM to update the Tech 2 it will cost you a minimum of $775 per year to update. The good news is the final update for the Tech 2 has already released. If you get a scanner with this version you will never need to update it again.
AcDelco allows you access to the Firmware "Calibrations" for the computers for $55 for unlimited 2 to 3 days access. So regardless of which device that supports programming you get that's what it will cost if you need to program the computers with the latest calibrations.
Ps. If you are looking for tool that is working well only, you can get a decent one from China, much more cheaper than the dealer. There are many good China clone, esp. Tech 2 scan tools

Corvette ZR1 Navigation Unlock with TECH 2: Done!

Here are tips and guides of navigation unlock with a TECH 2 scan tool
Car: I have a 2011 Chevrolet Corvette ZR1 that came with OnStar and Xm radio.
Purpose: I would like to swap the radio for a Navigation unit but remain with the stock Denso style corvette navigation unit.
Reason for navigation unit unlock: I purchased a Denso unit that came from a 2008 ZO6 and it worked when I fist plugged it in but after unplugging it the "Theft Lock" appeared on the screen.
I tried looking on ebay for unlock services and checked with a couple Chevy dealers but have not found anyone that says they can unlock it.
How to unlock a navigation unit using Tech 2:
You need an Tech 2 test instrument to unlock it.
The Tech 2 programs the navigation to the VIN number of your car.
The nearest Chevy dealer in my area should charge me an insane price to unlock it so I bought an Tech 2 myself. I don’t think they knew how to do it so gave me an insane price so I should not come to them, they had the Tech 2 instrument.
It was done in about 3 minutes, because I never used the instrument before.

The GM" >GM radios are VIN" >VIN specific, so the unlock process involves clearing the old VIN # from the nav unit, and allowing it to accept your VIN#. As I said, this can be done by anyone who has access to a TECH II. All GM dealers should have them, and if they tell you they can't unlock the radio, they are not telling you the truth. I went to my local Chevrolet dealer when I installed the nav unit in my 08 base. It's about a 5 minute job, but they charged me a 1 hour minimum labor $130.
I copied the how to shown below from a fellow forum member.
Here is how to use the TECH II to put the Nav unit into relearn mode:
Connect TECH II to car and put the car into acc. mode
At the main screen, select diagnostics
At systems selection menu screen, select body
At the VIN indent screen select
Appropriate model
Appropriate air conditioning
Nav radio
At the body screen, select Nav radio
At the radio screen, select special functions
At the special functions screen, select VIN relearn
At the VIN relearn screen, the scan tool will display, "do you want to clear the radio theft
information?"
To begin clearing, press the soft touch key on the top right of the scan tool. The TECH II will display "clearing theft in progress"
Once done, press exit on the TECH II and cycle the ignition
It's done and the Nav unit will now marry to your car.
The last, Technically there is no "jailbreak" for for OEM" >OEM Navigation radios" >radios for Corvettes.
Once a GM radio is initialized for the first time it learns the VIN" >VIN# from the vehicle and writes it to a flash within the radio. From that point on any time the radio is powered on the VIN" >VIN stored in the flash is compared with the current car VIN" >VIN # and if they don't match it throws up a TheftLock message (and/or lights" >lights a red LED" >LED depending on the radio).
All the technician is doing with the Tech2 is clearing the stored VIN# flash in the radio which causes the radio to relearn the new VIN # on next power-up.
My local GM service" >service dept. gave me the same speech when I asked about having TheftLock reset on a used OEM" >OEM radio(no guarantees resetting a used OEM" >OEM radio and no refund if they couldn't reset it) which is why I purchased a clone Tech2 to clear it myself (as well as be able to reprogram fobs on my other GM vehicles) and never looked back. I have now done several resets and BCM configuration changes for several local Corvette" >Corvette owners free of charge (ok, sometimes I accepted cold beer) and will continue to do so for anyone who asks.
That being said I posted detailed screenshots of how you reset the TheftLock on a Navigation radio here to make it easier for other members to do their own resets.
