Is there a satisfactory GM scan tool that will do relearns or flashing? I am more worried about a single system module (fuel, gearbox, body, etc.) instead of ECM.
And soon I’m doing the brake lines on my Silverado (the “dealer” repair was compression fittings ). I also want to do the ABS autobleed. My vehicles are 2000, 2001 and 2002, so I’m not too worried about being “Up to current MY” inventory, but it isn’t necessary that something upgradeable would be nice. Of course yes, let’s read the experienced users’ reviews.
No. 1 GM Tech2 scanner
Diagnosis: From 1991 to 2013
Programming: Year 2007 year (with Tis2000 Software)
– good scanner, works fine with isuzu trooper 4jx1 engine and aw30-40ls at
– I’d get a T2 clone and an MDI2 clone. There are things that I can’t do even with my T2 as as a pass thru with ACDelco TDS. The standalone T2 is good for diagnostic work without the burden of fumblefarting around with cables and a laptop etc.
– Works as it is supposed to and I got the job done right.
–My scanner has been nothing but awesome for several years.
BTW that Bosch/Vertronix Tech 2 technology has been in decades.. They spit out a boat load of Apple watches overthere before we get out of bed each day…a Tech 2 is like 486 / Pentium level technology.
If you need MDI (2010) then go there….
– The Chinese knockoffs are actually good.
While the Tech 2 is ancient…..It’s still a good handheld scan tool up to 2013MY.
– I’ve changed the fluid and replaced calipers and hoses on GM trucks and never had to do that, but assume any clone T2 would be able to.
Read related article: USA Cars (GM, Ford, Chrysler) PCM Flash Reprogramming Instruction. (It will use GM Tech2 scan tool)
Diagnosis: all Vauxhall /Opel 16 pin vehicles from 1996 to 2017
Programming GM: Yes
Don’t forget that you’ll need a subscription to GM SI to reflash any module in addition to the correct tool,
GDS2+MDI has been the GM scan tool since ~2010MY and the GM flashing tool since 2007
No. 3 AUTEL MS906BT
Autel MS906BT is a nice tool, Make sure if you buy, it is the “BT” version and not the cheaper MS906. You should be able to get a new one under $1200.
I have to say I’m very impressed with it supports to do things like your transfer case module, air bag modules, codes keys etc.
It is no issue to do some total brake line replacements on Chevy/GMC trucks, just bleed manually by myself.I just upgraded my scan tool to an Autel MS906BT .
No. 4 Launch X-431 V
There is also the Launch X-431 pro which works really well. And you can do other makes, access different modules, etc.
Just depends how much you want to spend.
The Tech2 clones work really well too.
