That means disconnecting the battery cables. You can hit the brake to discharge anything left.

Rigging stuff is definitely not the way to go unless you have some sort of an emergency. Hopefully, resetting the ECU will clear the code and solve the problem. If not, retrace your "rigging" steps to see what might have gone wrong.
