Hope you will not have any more issues. We have a 2008 GMC 3500 with IBC. We have had nothing but problems with this integrated brake controller. We have had failure 3 times, the DIC will show "Service Trailer Brakes" when there is an issue, when you have this warning, YOU WILL NOT have power to the Trailer Brakes. The first time this happened, we had to drive home without Trailer Brakes, happened while in route, not safe!! We have had this to the dealership for this, they did fix it ( replaced the relay) and told us this was common. We now have had this warning again on the DIC and again we have no Trailer Brakes. Truck is no longer under warranty!!! We are going to install an aftermarket P3, waiting for it to arrive.
