not really sure where to start.....I was driving home last nigh and the car died. I noticed that earlier in the day when I changed the heater core that the battery ran down for some odd reason. Charged the battery and all seemed fine till last night. i swapped the battery out and still got the same problem. The gear shift indicator lights blink on the dash. Ive had the pass key faults for almost a year with no running issues. Im sure some of the codes were set when I ran the battery down. Heres the codes that I have.
