Cold morning for us here in FLA. out of the blue I get AAS defective - auxiliary battery failure. No effect on starting or the mechanical operation of the vehicle. Distronic is out due to distance measuring out I think because the aux batt serves this bus. After several minutes of driving the annunciation goes away- not to return. I live on the gulf coast, 40’s are cold so…..this has not happened before but the vehicle is a 2013. Should I just get the AUX batt replaced or is it the cold temps?
