YOUCANIC Full System Scanner Best OBD2

Best OBD2 Scanner for DIY Auto Repair

Looking for the best OBD2 scanner that can diagnose your cars without having to go to the dealer? The best scan tools allow you to diagnose all vehicle systems on a vehicle. If you are looking for a professional-level scanner you need it to perform bidirectional testing as well which activates sensors, tests, resets, and even operates motors such as seat motor, window motor, fuel pump, and more.

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.
