I have installed new battery and had a/c leak tested . has error code 900e ,900f and 9703 when diagnostics was ran . any ideas what to do next?

Not an MB diagnostic I don't think?
So not sure what these mean - what's happening?

When you say leak tested, did the guys actually check the system was fully charged?

was working then just quit. had system evacuated and checked for leaks then recharged. compressor still not coming on so I replaced battery. had issue the same week end with warning lights coming on that the book said was a battery issue, battery was 5 years old so i went ahead and replaced it. when I had the diagnostic done it was with a snap on code reader code 900f said local over voltage at circuit 309 voltage more than 16 volts. 900e local under voltage at circuit 30 voltage less than 9 volts and 9703 fault in CAN communication with control unit n10 (front SAM control unit) I dont know what any of that means. the code reader said possible short in battery .
