1) 21A02D: Idle Irregular. However, my RPM is stable and no rough idling or other symptoms. Search the web and found that it may be a false code which require a software updates.
2) 48077C: Wheel electronics, Battery life, front life. NO ideal what is this code represent.

Anyone have similar experiences and remedy to share?
