you can reset the ecu by unhooking the car battery for an hour.
low voltage can cause auxiliary system failures and commonly does, but typically the engine runs fine and does not misfire just because there is low voltage
a simple low battery does not cause low voltage, as long as the alternator isn't faulty (nothing has been shared to suggest it is) then the car should run fine.
