Best OBD2 Scanner for GMC Chevy Buick Cadillac Vehicles – Tech 2

Are you looking for the best OBD2 scanner for GM vehicles? This article takes a look at several scanners that provide full diagnostic support for Chevrolet, Buick, Cadillac, and GMC vehicles.

If you are looking for affordable scanners that offer similar capabilities to Tech 2 Scanner then this article is for you.

1. YOUCANIC Full System Scanner

We tested a lot of scanners trying to find the best scanner to use in our garage. What we found is that:

  • Many scanner manufacturers make scanners that require a yearly subscription.
  • Can diagnose one make but doesn’t work on all different car makes. You will have to pay more to cover other vehicle makes.
  • Can’t diagnose all vehicle systems. May only diagnose the engine, airbag, transmission, and ABS problems. That’s only 4 systems. Modern cars can have up to 40+ systems.
  • Don’t support bi-direction support for sensor testing and activation.

If you wanted a scanner that can do all these, you have to spend thousands of dollars and most likely pay a yearly subscription.

So we decided to launch the YOUCANIC full system scanner that works on all makes and models.

The YOUCANIC full system scanner:

  • Works on all makes.
  • Can read and clear codes from all vehicle control units.
  • View live data from any sensor.
  • Bi-direction support to activate and test sensors and motors.
  • Reset functions depending on model

If that is not enough, keep in mind that the YOUCANIC scanner does not require a yearly subscription as other professional-level tools do. We believe that the YOUCANIC scanner offers the best OBD2 for the money for auto mechanics and DIYers.

Don’t want to buy a scanner? We still want to help you fix your vehicle in an economical way. We created a scanner rental program that allows you to use the scanner for a few days on as many cars as you like.

We have a ton of how-to video showing you how to troubleshoot car problems. Once you get the codes, the YOUCANIC technicians can help you with any questions you may have.

For owners, Tech2 is too expensive and is difficult to learn. The main diagnostic scanner used by GM dealers is the Tech2 handheld. The Tech 2 scanner covers GM vehicles back to the early 1990s.

 It can diagnose GMC, Suzuki, Saturn, Isuzu, Cadillac, Hummer, and Pontiac vehicles. It can troubleshoot even the new GM vehicles that use the CAN system. Since this is the OEM scanner, it provides a FULL diagnostic of all systems on your vehicle.



After testing hundreds of overpriced scanners, we were tired of overpriced scanners so we decided to launch the YOUCANIC Full System Scanner. which allows you to diagnose GM vehicles just like the dealer. In addition, it allows you to stream live sensor data. It’s a great tool for considering the price. 

YOUCANIC full system scanner allows you to diagnose other systems, such as airbags, abs, or traction control. For support with those models, check out the YOUCANIC UCAN-II scanner. 

For those looking to read and reset Check Engine Light, all you need is a basic OBD-II Scanner. The scanners we focus on in this article are more advanced and range in price between $100 to $800.

    Innova is a good choice. Not only because of the price, (which is suitable for homeowners) but also because it is so easy to use. People who are new to fixing their own cars usually find it a good option to start with.
    However, don’t get me wrong, if you have been fixing cars for a few years, the added options of more expensive models also become useful.

    This article was helpful unlike the countless review posts that I saw giving general information about the obd2 scanners. I decided to go with the Innova as that is within the budget. Autel seems to be a good choice to but too much money for me at this time.
