you can do the battery disconnect as many times as you want , sooner or later it'll just keep comming back on untill the problem is fixed, why not grab the code and see what it is? ive read bernie's posts many times about vehicles and have yet to see him type a word that wasnt true in regards to automotive repair, my older brother,father and his brother(uncle) and myself are all licenced mechanics in heavy equip,class A and truck coach, i can never comment on a auto request cause bernie just hits the nail on the head each time leaving zero room for a remark from moi.
