Consider Your Vehicle Brand

First and foremost, you will need to choose a car diagnostic tool, which is actually compatible with your automobile. When scouring through the available products, you will quickly discover that all products are only compatible with certain automobile brands. It is absolutely essential to choose a tool that will work fluidly with your vehicle. If you make a wrong choice and the tool is not compatible with your vehicle’s make and model, you’ll be forced to send it back for a replacement. Thankfully, some of the better tools are capable of accommodating up to 72 different car brands.


While you’re at it, you should realize that the majority of diagnostic tools will come equipped with some form of connectivity. Most are either Wi-Fi enabled or Bluetooth compatible. In some cases, your tool of choice might be compatible with both. Bluetooth connectivity will make it possible for you to connect to the diagnostic tool and monitor your vehicle’s status from inside and outside of your automobile. However, if you move too far away, the signal will not be strong enough. There is where Wi-Fi connectivity will be more suitable.

With a Wi-Fi compatible tool, you will be able to check your vehicle’s status from almost anywhere.


It is important to remember that technology is consistently changing. As time goes by, manufacturers of car diagnostic tool Android products will work to improve their tools. This means that they’ll release updates from time to time. Depending on your product, you may or may not be able to receive these updates for free. Some companies will offer a few years of free updates with your original purchase. Then, they’ll charge another fee for updates after that period of time has elapsed. Make sure you’re aware of specifics, before making the purchase!

Battery Life

Although it depends on the product at hand, many diagnostic tools will be equipped with internal batteries. This makes it possible to utilize the tool, without needing to connect it to your automobile’s battery. With this in mind, battery life will be absolutely pertinent. In general, it is best to opt for the longest battery life as possible. This will keep you connected for as long as possible before you need to recharge or replace the battery.

Languages Available

When looking for a diagnostic tool, you will want to make sure you look closely at the languages available. Some of these products are much more versatile than others. Some are capable of providing you with information in numerous languages, while others are only compatible with one or two languages. If you prefer something other than American English, you will want to make sure your diagnostic tool of choice offers it!

Tablet Optional

Some of these products are much more versatile than others. Some will only be able to provide you with basic error codes, while others will come with their very own tablet. While the tablet might not be a necessity, it will prove to be a good addition for many and will offer a wealth of additional functions. For instance, some of the included tablets can be utilized to take and store videos and photographs. If you’re willing to spend more and want the most comprehensive solution possible, you will definitely want to choose a diagnostic tool that comes with its very own tablet.


Last, but certainly not least, it is absolutely pertinent to carefully inspect the warranty provided with the product that you’re about to purchase. Remember that a longer warranty will make the product a much better overall value. While the warranty will not enhance the tool’s performance, it will go to great lengths to help protect your investment. If something goes awry within a few months of ownership, the warranty will help protect you and force the manufacturer to fix the problem for free!


Truly, all consumers should consider investing in the best car diagnostic tool that they can find. These tools are enormously beneficial and they will help keep your automobile in optimum condition. Just remember that not all tools are equal and some are only compatible with certain types of automobiles. Therefore, you will need to carefully analyze your vehicle and then use the car diagnostic tool reviews provided above to ensure you get the best product possible.

Below, you will learn more about the best car diagnostic tool products and how they work.

2 thoughts on “The Best Car Diagnostic Tool : Top Reviews & Buying Guide”

  1. That 2 year free updates offer is pretty sweet. It’s too bad they don’t offer a bit more; 3 would have been perfect for me. I’m not that happy about having to pay another $699 in my third year but even so I still think the Launch X431 V+ Pro3 Android OBD2 Auto Car Diagnostic Tool is still the best car diagnostic tool out there (if we take into account the price and quality this has). l also like that the battery life is good at 8 hours.

  2. I am a licensed mechanic and I have been looking for a good, reliable car diagnostic tool and after many products checked and a few hundred reviews read, I think I’ve found the right one. The Autel Maxisys Elite seems to be the correct tool for the job, with proper data storage which is essential in my business and free updates that are also important and for which you have to pay good money for in other cases. Overall, I think this is a good investment and I hope it pays off.
