  1. Use, Care & Maintenance - Gen 1 Chevy Volt
    My car started to display the message "Service Battery Charging System". I got it diagnosed by the dealer as a faulty APM. I found a few in junkyards near me and I want to do the work myself. Do I need to code the part to make it work on mine? If I do how do I do it?
