In extreme cases, such as the ECU not resetting, disconnect both cables (yep, even the ground cable) and leave disconnected overnight. In the morning, depress brake pedal 2-3 times for about 1-2 seconds apiece then reconnect the terminals. The capacitors in the electrical system may not always discharge completely when done briefly or only with the depressing of the pedals, so a slow decay may be necessary, which the overnight will do.
Good luck and hope this helps.
