PC 78 Error Codes

Have a PC 78 (2014), when I turn the key to start the machine, the console is displaying error codes DA2RMC, DAFRMC, and DA22KK, and the machine wont start, or eve turn over. . I have looked online, with little success in diagnosing these codes, they appear to be low voltage codes. Could that mean my battery is low on the machine. It has not been run in a couple of weeks. Any insight would be great
