    Hi. Here from Chile. I have a 2014 Silverado LTZ crew cab 1500 and suddenly the GM Smart charging system doesn't works. It's fixed 14.9 - 15 Volt. I changed alternator, ground cable with battery current sensor and battery. No change. I scanned several times and no DTC'S. Scanner display battery charge 65% and the BCM is command 80%. The next step, i Will look for a disrupt wire at side of PCM. Could be the BCM? No DTC'S.
