So I've got a 2011 RAM 2500, 2WD.

The trailer brake controller started flashing "CF" and said the trailer disconnected in the cluster, but no trailer was hooked up to the truck.

I hooked my scan tool to it, and it has fault C1000 in the ABS, and in the ITBM, it has fault U0415-00, and the WCM "wireless control module" has faults U0100 and U0121.

Any ideas?
