Troubleshooting Ford Factory Trailer Brake Controller that Fails to Operate EOH Trailer Brakes

Question

Question:

Hello, I have tried 2 trailers with this EOH part BrakeRite. I have a 2013 F150 max tow package with integral controller. Both trailers were installed by an authorized dealer. Both trailers work when connected to a toyota tundra. Neither works connected to my F150. If i use the manual actuator squeeeze controller in the cab, if I squeeze a few times the electric actuator pump will eventually work. The electric actuator pump will never work when I press the brake pedal. This is with gain set to 10.0 max. My truck brake controller is set to EOH. Ive ordered the 4846000 - but from all indications that was for pre-2013 when EOH vs Electric settings were not available. Do I install the 4846000 and see if that somehow fixes the issue?

The factory integrated brake controller in your 2013 Ford F-150 does have a second operation setting for EOH trailer brakes, unlike the 2012 and earlier model year controllers. So, it SHOULD work with your Titan BrakeRite EHB Electric-Hydraulic Actuator # T4813102 WITHOUT the adapter # DX35FR.

If you have access to a trailer with electric brakes you can test the controller (using its electric trailer brake setting, of course) to see if it functions correctly in that mode. If not it is probably all done and needs to be replaced.

Your story is quite common. Many folks that gave a shot to the Ford and Dodge factory controllers end up replacing them with a better and less costly aftermarket unit like the Prodigy P3 # 90195 simply because these proven brake controllers just work better in EOH systems. Factory controllers are usually fine with electric brakes though. You can use harness # 22292 to connect the P3 to your truck's under-dash port. The P3 works with both electric and EOH brakes. An install video for a similar unit is linked for you.

Answer 1

On a 2017 Ford Transit T250 without a factory trailer connector there is no brake controller adapter. What you would need to add a brake controller is wiring, the 4-Way #C56327 and 7-Way Brake Controller Install Kit #ETBC7. This kit gets plugged…

I agree that you most likely have an issue on the truck side. The voltage at the brake magnets when the vehicle is sitting still and the brake pedal is pressed will only read a small amount with the Ford integrated brake controller on your truck. If…

You can indeed test a trailer's electric drum brakes by directly applying +12V power from a fully-charged battery. You can apply this power to the hot and ground contacts on the trailer's plug (see photo please) or to an individual brake…

Answer 6

Since the trailer was off of the ground it would not take much voltage to stop the wheels from spinning so they may be getting power but they may not be getting enough power due to a short or wiring issue. But 9 times out of 10 weak trailer brakes…

Answer 7

Most likely you have either corrosion on the brake output pins of your trailer wiring or the pin was bent which is preventing the contact from being made. I attached a help article on brake controller troubleshooting for you to check out as well.

The lock up issue you are having shouldn't be related to the Engager Breakaway System part #20099 that you have installed on your trailer. There are other factors to consider when dealing with trailer brakes that lock up. You either have the gain…

The RoadActive Suspension (RAS) Custom Leaf Spring Enhancement Kit part #RAS3611-Y is what I recommend for a 2019 Ford F-150. The RAS Kit unlike the SumoSprings Solo Custom Helper Springs part #SSR-117-47 will engage right away so you don't have…

The correct replacement for the Oil Seal 225255UC is the Oil Seal part #9103309. These both have a 2.24/2.25" inner diameter and 3.37" outer diameter. They are also designed for use with oil bath hubs.

Answer 12

It should be getting close to 12 volts if the power output is set to the maximum on the brake controller. Some brake controllers will not work properly if they are titled or turned to the side or if it has a leveler knob that is not level. Check…
