Possible to use GM Tech 2 clone for HUMMER?

This is about GM Tech 2 scan tool 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 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.
