The battery disconnected or changed, so modules lost stored data. It is a recorded event rather than a fault, and the vehicle may be entirely healthy — the codes describe what happened.

What is lost matters more than the codes. Adaptations, learned idle and fuel trims, steering angle, throttle positions and radio codes; the vehicle can drive poorly for the first miles while it relearns, which owners report as a fault the battery work caused. On a vehicle with battery monitoring the replacement must also be registered, or the charging strategy targets a battery that is not fitted. Clear the codes and drive — what returns is real, and what does not was the disconnection.
