By any chance are your lights flickering? Like headlights or interior lights? I’ve seen several Hyundai’s have problems with a bad diodes causing both codes due to excessive AC ripple. Not saying that is your problem, but you could quickly identify AC ripple on a 2V scale with 10 ms per division. A bad diode would be .5v AC peak to peak.
