How to diagnose mechanical failures?

For several decades, cars have been using electronic technology to quickly determine the cause of several failures. The car suitcase is therefore a great success with drivers. Discover how it works and its interest in detecting mechanical failures.

What is a diagnostic case?

Technological developments have made it possible for modern cars to have an electronic system. Thus, most failures can be detected using a vehicle tracking tool. However, to carry it out, technicians need a diagnostic case. It is a computer pre-configured in a box to collect various information about the operation of the engine, starter, etc. This instrument can also be used to reprogram out-of-service components. The principle is simple. By connecting to the OBD-II (On-Board Diagnostics II) socket, the car suitcase computer receives real-time measurements from the many sensors in the vehicle. It has a correct range of values as a reference. If the result is not shown, the device considers the component in question to be non-functional. The diagnostic light comes on. Depending on the failure and the on-board tool, a car case may have the ability to reprogram the vehicle. The car case is useful for checking and maintaining the various components essential for engine operation. Thanks to this device, it is easy to check the braking system, safety components, tyres and maintenance indicators. It also offers the possibility for people unfamiliar with mechanics to easily understand the failure. Its immediate assessment of the general condition of the engine also accelerates the progress of technicians in their work. In other words, it saves not only money, but also time.

Which suitcase to choose for your car?

When you choose the most appropriate model for your car, the most obvious one is the manufacturer's suitcase. Indeed, it is well calibrated to understand the vehicle's defects. However, it is not easy to find them. We can therefore turn to a multi-brand automotive diagnostic case. It is more general but offers satisfactory results. There are models compatible with the gasoline engine and others with the diesel engine. A diagnostic case also provides a lot of qualitative data by sending anomaly codes discovered on the engine, battery, etc. The information is accurate and fast.

Tips for a good diagnosis

To properly establish an auto diagnosis, in general, it is necessary to investigate the causes that may have caused the failure. This helps to understand the signs and symptoms. After the accumulation of data, we continue with their analyses. Then, we look for the location of the failure, eliminating all the positive points. We're trying to understand why the rift was triggered. This condition prevents the repetition of the "pathology". Once the phenomenon and its essence have been identified, we can now move on to the repair stage. After completing the latter, the system is checked before putting everything back in place. For complex systems such as injection or ABR (Anti Wheel Lockout), there is often an integrated self-diagnostic system to help the mechanic identify the problem. Technical brochures can also help to understand the system for quick troubleshooting. Although the multi-brand diagnostic case makes it easy to draw defects, it is therefore necessary to follow these steps in order to avoid repetition. It is therefore advisable to seek professional advice.
