If voltage gets too low, it can trigger these types of codes. How old is the battery, and how many miles on the car?

Well, your alternator should be good with that mileage. Sometimes there is an installation sticker on the battery; if it’s over 5 years I would just replace it. Otherwise, charge it up, clear codes and keep an eye on it.

If you reset the codes using the code reader and they still came back, I would do further diagnosis before throwing money at parts. The codes are for different systems, with the low voltage being the common item among them.
