Been lucky enough not to get error codes on my Gen I, but upon reading these posts, I hear that to clear some "error" codes you disconnect battery. Instead of that hassle, can you just unplug the DOME fuse located in the engine compartment, or does this just cancel the assessories, and not the codes? If not, what is a good brand of battery disconnect switch (the kind you just twist a knob to kill power completely) Just saw cheap brass ones with green knob that won't work on the Prii. Suggestions would help
