Electrical malfunction and error code U0077 in an Opel Corsa

Hello everyone, I have a 2016 Opel Corsa E with 98,600 km and I'm facing a problem. When I read out the vehicle data, the error code U0077 is displayed. Recently, the check engine light came on while driving, but went out by itself. A few days ago, the tires were changed. Does anyone have an idea what could be causing this error and how I can fix the problem? Thank you very much for your help!

The error code U0077 typically relates to a communication issue within the vehicle's control modules. Start by checking the battery connections to ensure they are clean and secure, as poor connections can cause communication errors. If the problem persists, it might be worth inspecting the wiring and connectors for any signs of damage or corrosion. Let me know how it goes or if you have any further questions!
