Diagnostic tools are essential accessories for quickly detecting a possible anomaly in a car and being able to correct it if necessary. Many models are available on the market, each tool has different functionality and at very variable prices. In this article, we will guide you in choosing the right tool at the best value for money.

 WHAT ARE THE EXISTING DIAGNOSTIC TOOLS?

In order to carry out the diagnosis of a car, it is necessary to use an auto diagnostic case. It is a very important accessory for ensuring good management of the electronic systems onboard a vehicle.

This tool facilitates the repair of modern vehicles because they have more and more technology and it is more difficult to identify the source of breakdowns. Also called “fault code reader”, it offers an in-depth analysis of the functions of a vehicle and quickly identifies the slightest malfunction as well as its origin. This helps prevent the occurrence of failure. This software-equipped device plugs directly into the car using a standard OBD2 connector with 16 pins.

An auto diagnostic case takes the form of a box with a black and white or color screen depending on the model. In addition, it has a classic key system (up, down, right, left).

There are many variations of this tool with different degrees of accuracy and varying prices. For example, some recent suitcases are equipped with the best technologies like Bluetooth and WiFi to download additional software or applications.

ARE THERE DIAGNOSTIC TOOLS SPECIFIC TO EACH BRAND OF CAR?

In order to choose the right diagnostic case, you have to find the one that best suits the vehicle in question and its type of engine. There are two types of cases: those with a box specific to each brand and those with so-called “universal” multi-brand boxes.

For an individual, the auto diagnostic case dedicated to the brand of his vehicle is the best option. However, for professional use, it is strongly recommended to opt for a multi-brand diagnostic box. Indeed, this type of box is universal and will adapt to all types of vehicles, regardless of their make and model.
