Last night, my abs dash light come up but the abs system was still working (it was -26 farenheit outside). This morning my battery was dead, I didn't forget any lights inside. ( The car pass the night outside at -29 farenheit) I don't know if it is related or not, maybe the abs system was still working even if my car wasn't running and decharge the battery??? I boost it and it take many try before it started. The day before it was -22 farenheit and the car start at first try.


Any idea of what can have cause this?
