Yes, but you don't have to unhook the negative terminal.
Just pull the only 3 amp fuse in the fuse panel under the hood. That will reset the ECU of all codes and let it relearn everything again. It will idle rough when you first start it, but after about 10 mins of driving it will return to normal. If it is fixed that is.
Pulling the fuse is easier than the negative terminal, and will not reset your clock and radio.
