Q: What does code U0092 mean?

CAN Communication Bus "C" Performance. U0092 means the vehicle's network of computers detected a performance problem on CAN (Controller Area Network) communication bus 'C', which is one of the high-speed data links that modules use to share information. The computer sets this code when messages on that bus are missing, corrupted, or arriving outside the expected timing window, so the modules cannot reliably talk to each other.
