There is no harm in pulling fuses and disconnecting the battery...but also, no benefit. There will still be stored codes. I would get a decent copy of Vida - I think I paid $100 for mine, including the multiplexer, and put it on an old laptop. If you don't have an old laptop (I think mine runs in Windows 7), then a Foxwell NT530, for about $170 on Amazon, will read and clear all possible codes.
