Haven't heard that one before, but doesn't mean that it won't work. Here's something a little quicker, disconnect neg battery terminal for at least 60 seconds, then depress brake pedal for a minimum 10 seconds, reconnect neg terminal and that's it.
We all know that there is always a constant current feed to the brake lights at all times irregardless if ignition is on or not. By depressing brake pedal you're doing the same thing - draining any transient current remaining in cars electrical system (including ECU).
