Code 41

Good morning,

You need to charge your battery. it needs to be at 12.4 to 12.6 volts.

https://www.2carpros.com/articles/how-to-charge-your-car-battery

code 12 is low voltage and 10 volts will set the code.

code 41 is for the charging system. it could be either the alternator or the voltage regulator.
