Honda Brio Fault Code

Hey there! I also drive a Honda Brio. I recall having similar issues a while back. Did you try reading the fault code using a diagnostic scanner? It could be related to a misconfiguration in one of the car's control modules. When the car's computer (also called ECU) is not correctly configured, it can lead to all sorts of error messages. It is possible that the car needs new coding. Have you noticed anything else unusual, like performance issues?

Thank you for your reply! I did use a diagnostic scanner, and it returned a generic fault code related to the vehicle's main computer. However, I'm not entirely sure how to interpret it. You mentioned 'misconfiguration' and 'coding'. Could you please elaborate on what that means and whether it's something I can fix myself? Does that require a reset of the codes?

Okay, so a generic fault code and error messages in multiple places strongly suggests a coding issue. Basically, modern cars have lots of small computers (control modules) that communicate with each other. They all need to be programmed correctly to work together. If the coding is off, or gets corrupted, it can throw errors like the ones you're seeing. Unfortunately, this isn't usually a DIY fix unless you have specialized software and knowledge. I'd recommend taking it to a trusted workshop; they'll have the tools to diagnose and recode the affected module. It could be something as simple as needing a software refresh.

I appreciate your help and advice. I took my Brio to the workshop, and it turned out the car's main computer had incorrect coding, just as you suspected. The repair cost me 360€ to recode it, but at least the error messages are gone now! Thank you for pointing me in the right direction.
