How to perform a system diagnosis on Opel Combo E

Model: Vauxhall Combo Combo E, MK 5 - Years 2019-2026
Part: Onboard computer

Let's see how to access the system diagnosis on the Opel Combo E: first, we turn on the electrical system, and from there we access the main menu via the multimedia screen. We enter the "diagnosis" menu and check the messages displayed in a list called "all car messages." Here we can see if there are any error codes or messages recorded by the various systems of the vehicle. These can indicate which system has detected the anomaly, greatly facilitating maintenance. Of course, this is not a professional scanner, but it provides only basic information; it does not read specific fault codes like a diagnostic tool would, and, equally obviously, it cannot erase error codes. To perform this operation, a scanner (even a simple one) is needed via the OBD port.
