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