Truck: 2022 Ram 3500 DW Diesel – 4,800 miles new
- Took the trailer into a Grand Design Dealer for a recall on Refrigerator wiring harness; while there they did an inspection, repacked bearings, replaced backing plate on Drivers side front wheel.
- First Trip of season – No issues
- Second trip of season Trailer brakes “disconnected” appeared on truck console. I pulled to the side of Hwy and verified all connectors were secure and lights at rear of vehicle work as expected. We were 20min away from camp so just got back on the Hwy and took it slow. The brakes were intermittent, coming and going with no rhyme or reason. By the time I arrived at camp, the brakes were working fine, so I couldn’t isolate if it was the truck or trailer.
- While on “Vacation” I took the truck to the local Ram dealer who checked it out and said the truck looks good, but it did store a code – C10C7-19 “Electronic Brake controller output-over current”. In short, they told me it’s the trailer’s fault.
- Had a mobile RV tech come out to camp who did visual inspection of the underbody, took apart connections at pin box and reconnected (but said everything looked tight). He was thinking it has more to do with a poor connection between the 7 pin blades. He bent the blades a bit to make a tighter connection.
- End of vacation – 5 minutes on the road and the brakes go out again. I moved the 7 pin connection from the bed of the truck to the bumper – still no brakes. I decided I would drive her home cautiously and then straight to the Grand Design RV Dealer. Once on the Hwy, the brakes started working again and it was smooth sailing the whole way home and to the RV dealer.
- Picked up the trailer today. The dealer said there was a clip “missing” on the right rear brake to hold the magnet in place, but no other issues were found ($300 for a $1 dollar clip). 40 minutes into my drive home the brakes when out again and very quickly came right back on. That is until I was at my exit. The second I stepped on the brakes the light came on the I lost brakes. Fortunately, this truck is a beast and was able to keep me on the road and the people in front of me from becoming pancakes. But this is dangerous.
Any help would be appreciated gang.
