Best Answer

U0002 = High Speed CAN Communication Bus Performance. This is a generic code.If you leave certain accessories plugged in your 12 volt supply (such as charging certain cell phones) it may set that code. Not all accessories will cause this. Some accessories will back feed the system when the vehicle is shut off, confuse the circuit and set that code.
