How to make an automobile diagnosis?

With the advanced technology of today’s cars, a large majority of breakdowns can be spotted thanks to the vehicle’s diagnostic systems. However, in most cases, the consultation of this system will have to be done via a “diagnostic bag”.

Principle, case and connectors

hhshsdfjseddhheeeeeeeAs far as the principle is concerned, the ECU constantly receives information from the various sensors on the vehicle. It has a correct value range, beyond this range or in the total absence of a signal, it considers the element concerned to be out of service. This causes the diagnostic indicator light to illuminate. It can also compare the information of the different sensors and see an anomaly.

The “diag” case allows you to read these faults by connecting to the diagnostic socket such as OBD or OBD 2. These same sockets allow the reprogramming of the auto but require a more sophisticated tooling. The software interface translates the default code into French to make it easier for the user to understand. These car cases are often supplied with a range of plugs and adapters to connect to all existing systems.

During playback, the user can see whether the fault is fugitive (shown X times and then disappeared) or permanent (present on the vehicle at the time of the diag). There are many ways you can purchase and obd2 scanner.

How to get one

You can choose between purchasing the USB cabling or connecting it to a PC on which you have installed an interface software, or buying a portable box directly to read the faulty codes.

Unfortunately, the majority of these boxes and interfaces have a limited range of actions and will only allow the reading of faulty codes and their deletion. It is quite understandable that access to more advanced functions such as reprogramming keys and disabling the anti-start function are difficult to obtain because of the fraudulent use of this function (car theft).
