Modern cars are complex mechanisms in which electronics, components, and assemblies can periodically fail. Typically, in such cases, an error is recorded in the memory of the onboard computer, which can assist in diagnosing and resolving the issue. However, the cost of diagnostics is significant, and not all car owners are willing to seek it out. This was reported by an auto electrician in an interview on the portal naavtotrasse.ru.
Interestingly, it is not always necessary to go to a service center to detect faults. Some vehicles have alternative diagnostic methods. For example, in vehicles with a manual transmission equipped with a modern onboard computer and display, owners can read errors themselves by following a specific sequence of actions.
To do this, you need to simultaneously press the gas and brake pedals, then turn on the ignition without starting the engine. After that, the onboard computer will perform a self-diagnosis, and the error codes will be displayed on the screen. The driver will only need to refer to the internet to decode the received codes and determine what to pay attention to.
In cars with automatic transmissions, the process will be slightly different. As with the manual transmission, you need to press both pedals, turn on the ignition, shift the gear selector to Drive, and then turn the ignition off and on again. There is no need to start the engine. After this, you can use the switch to view the error codes and also refer to the vehicle's technical description for their decoding.
It is important to remember that information about error codes and their decoding can be found in the vehicle's technical manual or online. As for resetting errors, some of them may disappear when the battery terminals are disconnected. If diagnostics reveal serious issues, it is recommended to visit a service center for a more detailed examination and repair of the faulty sensor or component.
It is also worth emphasizing the importance of regular diagnostics and error resets. Neglecting these procedures can lead to the onboard computer's memory becoming full. The accumulation of errors can cause serious malfunctions in the vehicle's software, which, in turn, may disrupt the functioning of individual systems and controls.
