I have 1000miles on my new gmc 3500 hd, pulled my camper and had brake wire short to ground inside brake drum. repaired connection and had to replace 30 amp fuse under hood. now the service trailer brake system came on and truck will not recognize trailer and brakes will not energize. is it the control module that has taken the hit? and if so is the same module used for the 2017,18,19? I know it should be under factory warranty but we have a big camping trip scheduled this week. just working on plan B
