hello everyone. Ok not for sure if this is posted in the right forum if not I appolegize. I'm lookin to invest in a not crazy expensive scan tool. I'm thinking about the Tech II scan tool. Was wondering if anyone could give me some feed back on a decent scan tool or if the tech 2 would be a good choice. Hope to get some useful info about a good choice on a scan. Thank you in advance.

Depends on what you are looking to do. I had a tech II and it is ok. But sold it and got a Snap on scanner as it worked on way more vehicles but was thousands. If you are only doing yours or gm look at nano it is $120. But also allows flashing gm updates but you pay for that also 40 per vehicle for 2 years. Then there are cheaper code readers.
Of if you what more power a tuner device such as HPT will scan, data, remote, write, read. You need a laptop but all major components are available in that. As well as clearing codes and tuning. Also one device works on gm,Chrysler,ford,ect...
But again it is tuner based.

I'm happy with Autogenuity w gm enhancement (windows software + a usb-obdii cable).  Reads codes from all the computers on the vehicle, also performs a variety of testing and diagnostic procedures, live data recording.  It's just below the tech ii in functionality for gm vehicles (as it can't reflash the computers, might be missing other things, but I don't know what).

Isn’t the tech 2 for 2013 and older trucks and need GDS or whatever it’s called for 2014+? I’m sure you can read codes on the new trucks with tech 2 but if you want full bidirectional control you need the newer tool.

If your needs are high tech, the above options are good. If you're only a tinkerer like me and you just want to read and clear codes, something like this is cheap and effective:

connects to your phone via wifi and you can use a free app to monitor live data. There are several similar.

Tech 2 doesn't work on 1/2 truck newer than 2013, on HD newer than 2014 and on Tahoe/Yukon/Suburban/Escalade past 2014.

 

2014 1/2 ton, 2015 HD and 2015 full size SUV are GM's Global Diagnostics System or GDS/GDS2.  That requires a laptop and active licensing from GM to operate.

It's sounding like the snap on scanner may be the way to go then for us.
Yes it is big money but read all. And is great tool. I would base it on use. If you are a mechanic and the tool can pay for itself go for it. If not maybe the $120 and license is best, if just one time or when there is a issue then the 100 bluetooth scanner will work.

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
