i think that is right, plus I think we screw with each other quite a bit, making import and export a little more dodgy. How does that song go, “pressure, pushing down on me..”

not sure on the duramax I have used it on a nnbs suburban 2500 (6.0)
I don't se a de-facto list, it just say's 92-2009 (most vehicles) after that they started to move some to GDS2

I purchased mine from a california vendor (same vendor Wes mention) and got it in 3 days.

Everything I've read suggests these Tech 2's will work on my Duramax, without stating it outright. Either way, I still have three other vehicles it'll work on. I followed Wes' link and bought it off eBay. Thanks for that, Wes. And thanks to the rest of you for your help.

Got mine in yesterday. It does work on my Duramax, so that's a plus. However, I noticed when the unit does its "System Initializing" thing, the results show a "pass" on everything but line 7, which is RTC, and it fails. Does anyone know anything about the startup tests on these? Thanks.
Kinda curious as to what that is. I never pay attention so idk if mine passes that.
Not sure what test mine kept failing, but I know mine did that at first, but I think after I learned how crazy effing tight you have to get the cable attached on the Tech2 end, it stopped happening. Might be worth a shot. I would be in the middle of trying to look at something, and it would drop communication constantly. Now, I wrench those suckers, and don’t seem to have the issue anymore.
RTC is Real Time Clock; apparently it doesn't affect the functionality of the Tech 2. But I am also reading that there is a battery in it, and I guess I need to check mine to see if it has one and where it is.
Ah yes. Just like in a motherboard. Probably a CR2032 even. Lol.

I'm having that same issue--dropping communication. I pushed it as tight as it would go, and there's none of that plastic flashing in the plug.
I pulled the front cover off of mine (6 T20 screws from the back) and do not see a battery, although my time is correct. Since it's not broke I'm not disassembling any further. The battery might be on the circuit board under the screen.
Maybe you just need to SET the clock?

I may have done it a long time ago; it had the correct time when I checked it tonight.

I had to watch mine about 12-15 times before I could determine what was the failed test; the initialization results stay on the screen for only a fraction of a second.
Mine kept redoing the System Initialization, so I knew something was loose. I did like you and put a monkey grip on the screws where the cable plugs into the bottom of the Tech 2. I was a little concerned that I was going to strip one of them out. No more unexpected restarts since.
Okay, that makes sense. I know that "fail" has no impact on the readiness of the scanner because I get the single beep at the end of the initialization process indicating everything is okay, and the scanner is ready to go.

You might try wiggling the plug a little as you seat it in the Tech 2, then twist the screws as tight as you can without twisting the plastic caps off. I've found that mine are surprisingly strong. (If you haven't already tried it.)
apparently there is a battery on the backside somewhere can't find any photo's of it though
I checked mine when I was out there trying to find the wheel dimeter input. My clock if off a few hours, but remarkably has everything else correct.
Still couldn't find the wheel diameter input in the chassis/ABS Special Functions section, I think maybe my model year doesn't have it.
Maybe you just need to SET the clock?
I tried to set the hours to the right local time but when I push the soft key to save, nothing happened. No big deal, I think I will call it good.
Yup. This.

Mine also has the RTF failure, replacing the battery didn't help. Doesn't seem to matter. The 2032 battery is indeed under the screen if memory serves. The old battery was still good.
