Just wanted to give you guys a heads up, there's a service update for 15s #15115 that has to do with a reprogram of the GPCM to limit IAH voltage to 13.5 volts to prevent excess heat and possible fires.
Just had a pickup come in that had this reprogramming done a few months ago and the IAH was scorched pretty good, the black plastic cable cover was melted and the cable had some burns. Just wanted to give guys a heads up and to keep your wits about you:thumb:
