All cars, which we once would have called modern, but in reality the OBD protocol has existed for some time, allow you to query various control units and check their operational status through the OBDII diagnostic port and appropriate diagnostic tools.

In this way, in addition to reading and possibly clearing error codes, it is possible to check operational parameters and also perform some resets (such as the SERVICE reset).

In the past, all of this was exclusive to dealerships as diagnostic equipment capable of performing the described tasks was not available on the market, but now it is possible to find diagnostics that are actually equivalent to the official ones: you just need to search well.
