Question about Ford integrated brake controller
I have a 2013 Ford F150 with the integrated brake controller and I don't think it's working right. I can't get the trailer brakes to “lock up” according to Ford’s owner’s manual. I tried at low speeds (under 10mph) as well as a little faster (above 25mph). I initially thought it was an issue with my new travel trailer so I took it back to the trailer dealership and they said everything was fine so they suggested it was an issue with the truck. I took my truck into the Ford dealer yesterday and they said everything checked out just fine. No codes are showing up indicating a brake controller problem and they showed me it's getting full volts when applying the brake at the pedal and the manual pull. I even tested it on a friend's cattle trailer and couldn't get his brakes to lock up either with my truck but he is able to with an aftermarket controller. Both the trailer and truck dealerships are saying their equipment is fine so I'm at a loss at this point. All I can do is set my controller all the way up to 10 and hope for the best. I'm even considering pulling the factory controller and installing an aftermarket one just to see if that makes a difference which would stink since I like the way the factory one integrates with the truck. Just curious if anyone else has experienced this with their trucks?
