Our Review about best car diagnostic tool in 2023



The first diagnostic tool we are going to look at is from Autel. It is the MaxiLink ML619. This scanner is a great size at 1.95 pounds and measures 7.3 inches x 10.2 inches x 3 inches. This size makes it easy to use and fit in your hands.

The screen on this code reader is also a perfect size. The screen is bright and easy to see in all lighting conditions.

This diagnostic tool is also great because it comes with the main cable, a USB cable, 16 GB micro sd card, carry case, and user manual so it is ready to use out of the box.

One great thing about this scanner is that it works on a wide range of vehicles. It should work on anything 1996 or newer from all the major brands such as GM, Ford, and even BMW, Toyota, and other foreign cars. This is good because some diagnostic tools don’t work on everything. It is important to check though to make sure this will work with your vehicle before buying.

Users really love that this scanner comes with free lifetime updates. That means that if you get a new vehicle you shouldn’t have to get a new scanner. It is easy to update this one as well. All you have to do is hook it up to the computer and run the update on it.

The ML619 is a solid all-around scan tool. It can read all the basic codes such as P0, P2, P3, and U0. It can also read manufacturer specific (P1, P3, and U1) codes and pending codes. It can even check the ABS and SRS system.

On top of all this, the last thing it can do is graph live date so you can see how well your vehicle is running. If you are looking for a top quality diagnostic tool that can do it all, then the Autel just might be the best one for you.

The next diagnostic tool we are going to look at is the Innova 3100j. This scanner is another one that is the perfect size. It is only 1.01 pounds and measures 10 inches x 8 inches x 1.5 inches.

One downside with this scanner though is it runs off batteries and not power from the car. That means you have to have three triple A batteries ready to use it. The batteries do last for a while though.

This scanner is easy to use and will read the codes fast. The screen is bright but smaller than the Autel. This scanner works on most makes and models 1996 or newer, but again it is important to check to make sure it works with your vehicle. The scanner can save the last three scans as well which is a useful feature.

The 3100j can check all the basic codes. It can also check ABS and SRS lights. It can even test the alternator.

On top of this, it can reset your oil light and do a freeze frame check on the engine condition. This means it can let you know the coolant temperature while the engine is running and things like that.

Users really like the Innova and how easy it is to use. They also like that it has custom repair solutions online that you can look up so you know exactly what each code means. Lastly, if you go with the 3100j you get access to customer support, so if you ever have a problem with your scanner, you can get an answer fast.
