The cryptic warning, however, doesn’t imply what should we check, or what could be the problem with our car, forcing us to have a mechanic look at it, which isn’t always easy on the budget.

In the early stages, most diagnostic scan tools could only read the code of the fault, without any further clarification for the driver as to what exactly the problem is. Nowadays, diagnostic scan tools have evolved greatly, so you can expect to both read and clear codes, and, depending on the model, suggest a method of repair, or even enable you to customize your vehicle’s default system settings. Most average diagnostic scan tools on the market cost same as what mechanic would ask for diagnostic, sometimes even less, and by buying your on diagnostic scan tool, you’ll save money both immediately and in the long run.

But, with a proper diagnostic scan tool, you won’t be only saving money on unnecessary visits to a mechanic, it can be a real life-saver in cases when you’re not around one, and need to rely on your own skills to get the car going.

Whether you want to save money or just want to have a reliable scan tool to monitor your car’s overall state, a good diagnostic scan tool is the best possible investment.

Is my car compatible with diagnostic scan tools?

Cars manufactured in 1996 for American market and in the years after that are equipped with OBDII software, or On-Board Diagnostic, which allows access to your vehicle’s on-board computer. So, if you own a car that is not older than 20 years, you can use diagnostic scan tool to check for faults and fix problems with your engine, or depending on the model of the car, even problems with some other components of your car.

Not all the cars are the same, as well as diagnostic scan tools. Some cars will have more components covered with their OBDII software, and some will only cover engine. Some cars can even be customized with proper diagnostic scan tool, which, according to The New York Times, can help you increase or limit speed, and generally teak your car’s performance so it would suit your needs perfectly.

You might not be able to customize your car’s settings if it’s not a supported model, but, one thing’s for sure- all cars manufactured after 1996 for American market are compatible with diagnostic scan tools, even if only to read and clear engine codes.

How we tested

After thorough research, we chose 10 diagnostic scan tools to test and to try and find the best diagnostic scan tool for most people. It took us over 50 hours to test them all on several different car models, in order to truly see how well they work and which one of them offers most for their value. In order to check if these diagnostic scan tools really deliver what they promise to, we consulted four mechanics to confirm the validity of their performance.

Of course, when we tested different diagnostic scan tools, we were mostly interested in their diagnostic capabilities. The more the tool offered, the better- so any additional feature besides reading and clearing codes was a welcome one, and could only improve our rating. Diagnostic scan tools that offered explanation of the codes, or suggested fixes and repairs for problems we encountered were favored, since they significantly improved do-it-yourself diagnostics and had the potential to save a lot of money that would be wasted on a mechanic.

Another important quality was the ease of use. Every diagnostic scan tool only requires to be plugged in your OBDII socket in the dashboard, but, some of them have cables and need to be handheld, while other models are in a form of a small dangle, that you can just plug in and leave in for as long as you want to. Additionally, diagnostic scan tools who only read codes, without offering an explanation were really hard to use- it required a lot of work to find the meaning of the codes manually, while other models offered the explanation on the spot.

In addition to OBDII diagnostics, some of the diagnostic scan tools we tested offer advanced diagnostics, like ABS, SRS, airbag or transmission codes, and it was a big bonus- every scan tool that can do enhanced diagnostics accurately in addition to OBDII is a good buy.
