I know this is a old post , but has anybody have any luck finding a solution? My 2015 2500 started doing this , I check each door and I've unplugged every switch to test , when I remove the fuse for the bcm for power locks it haults it but you can still here it trying to work, when I unplug the pink connector on the bcm under the dash it stops doing it , I've checked my wires and they look good , I've taking the batteries out of my key fob and cleaned all battery post , could it be the immobilizer in the roof or bad bcm?
