Thank you TwinSnailz for your replies and helpfulness. I ordered the Battery Current Sensor cable (negative battery cable) from rockauto today for $150 and will replace it when I get it in. I have also heard that it may have a parasitic draw that is causing the battery to lose voltage while parked. It makes sense that if the IBS is bad it wouldnt know or properly regulate battery voltage resulting in the vehicle believing it is unplugged, but since I cant find any way to properly test the IBS itself and since there are no error or fault codes present on a Carly diagnostic test I have to blindly replace the IBS cable and cross my fingers that it fixes the problem. After replacement of the negative cable, will I get a battery fault stating that I need to re register the battery as new?
