If you own a car, you likely know this vehicle can be incredibly useful these days- especially when you’ve run out of groceries and need to go to the supermarket as quickly as possible. Cars allow you to commute anywhere you want without relying on public transportation. If you are a busy person, you probably give daily thanks to your four-wheeled vehicle for making your life easier. However, cars can sometimes break down, and when something goes wrong, it can get stressful – especially if you don’t know much about their mechanics.

So, typically, the only thing you can think of is to take it to a professional to solve the problem. But we all know how costly that can be. Fortunately, there’s no need to do this whenever an unusual sound comes from your vehicle – you can perform a car diagnostic test yourself. While it may sound complicated, it is actually more straightforward than you’d think. In this blog, we will walk you through the process of determining possible car issues through a diagnostic test, so keep reading!

How often is a car diagnostic test recommended?

It’s common for car owners to take their vehicles to the mechanic only when there’s a serious breakdown, and that’s understandable, given that it is both costly and time-consuming to do so. However, this wouldn’t be necessary if you prevent these problems from happening in the first place. By learning to perform a diagnostic test on your own, you can do it as regularly as possible, thus detecting minor issues early on and fixing them before the problem worsens, costing you hundreds- or thousands – of dollars.

What are the steps involved in a car diagnostic test?

Although it may seem like you need a lot of professional knowledge to perform a car diagnostic test, that’s not the case. As long as you have a reliable diagnostic tool, it will be easy to identify your vehicle’s problem. Such a tool scans the components of your car, trying to find any existing issues in the ignition system, oil tank, accelerator, engine, and so on. A car diagnostic tool can come in handy, especially if you experience issues with your car when there’s no nearby mechanic to access. This tool can save your day in such situations, providing you with a quick and accurate vehicle diagnosis, thus helping you decide which action to take next, whether that means calling the towing service or fixing the problem on your own. Although it may seem that a car diagnostic tool implies many technicalities, it is actually easy to use; all you have to do is plug it in and press scan, and you’ll immediately see the results.

Each car has an incorporated OBD (onboard diagnostics) system that provides codes that allow you to detect what is going wrong in your automobile. Although these codes don’t exactly tell you the problem, interpreting them gives you valuable data about the potential issue and how to detect and fix it. Different OBD interfaces are available, so there should be no problem finding something suitable for your car model. Moreover, you don’t have to worry too much about the cost, as these devices are affordable, offering an easy-to-understand diagnosis at a superior level. Keep in mind that not all interfaces are ideal for beginners, so if you’re new to this, take the time to do your research before purchasing diagnostic equipment for your car.

Here comes the hardest part – understanding the codes. Don’t worry; it’s not rocket science, even if it may seem so. First of all, you need to remember that the codes will begin with a letter pointing to a specific system, whether the airbags, engine, axles and so on. For example, B stands for the Body and covers the airbags, power seating, seat belts, and more. You’ll also have to learn the meaning of the numbers. All car models have generic codes (P0xxx, P2xx, and P3xx), with the last two digits of the code referring to a specific issue. You can look for code charts online for more details on each particular code. As long as you use a guide on diagnostic trouble codes, navigating the process of understanding what’s wrong with your car will be a lot easier. Fortunately, the Internet has plenty of them, providing detailed explanations of the symptoms, possible causes, and even simple fixes.  

It’s worth mentioning that not all car problems can be fixed individually. It’s perfectly fine to do that if there are minor problems and you can decipher the reason why your car is malfunctioning. By using Google and YouTube tutorials, it should be easy to make your car work again. However, suppose your diagnostic tool reports a more serious issue; in this case, you should take it to a professional so that they can properly repair your vehicle.

It’s not necessary to be an expert to perform a car diagnostic test

A car diagnostic test may seem complicated, but as you’ve probably figured out by now, you can do it on your own easily and effectively, saving both time and money. Car diagnostic tests are essential for your automobile’s health, so you shouldn’t overlook them. Obviously, if you’re looking for a hassle-free option and don’t mind spending so much money on your car repairs, you can always take it to a mechanic. That’s also the case if you don’t spot an issue that requires professional intervention. However, in most cases, complex repairs aren’t needed, and you can avoid unnecessary payment by investing in car diagnostic equipment and sparing some time to read online guides on understanding OBD codes.

No one ever wants their car to break down in the middle of a road trip, but these things can happen unexpectedly, which is why we recommend getting a diagnostic tool. Since it is compact and small, you can bring it anywhere, and whenever something goes wrong, simply plug it in and perform the diagnostic test yourself without worrying about finding a nearby automotive repair shop. Ultimately, this will give you peace of mind during your trips, allowing you to drive your car seamlessly.
