yes ash is correct, i did not see this post and i replied to your other one. on this code alone p0615 you most check everything ash suggested if the other code is showing first then an immo issue is most likely the cause or bad bcm, a bad fuse box or ground is also known for code p0615 good luck. do an auto scan of all modules, erase everything and see if you can duplicate the problem and report trouble codes, the first code to pop up is attack first.
