Im getting this almost every time I start it up. It happened once about a month ago, then more often. Now almost every time.
Truck has 1700 mi
I hate to have to bring it to Ford so soon
2010 F250 Lariat, cab and a half, PSD. 5600 miles.
Sunday I started the pickup and received "trailer brake module fault" in the message center. I wasn't pulling so wasn't too concerned - hit the reset and continued on.
Sunday night I started the pickup again and received the same message followed by "check brake system". I also lost illuminated gear selection, the traction control active symbol was displayed and the traction control "off" (PB) was illuminated. After several attempts it reset, everything returned to normal and I was able to get home without incident.
Monday morning it wouldn't start. It indicated "trailer brake module fault", "check brake system", traction control active and off, no gear indication, the odometer indicated "-------" and it did not react to the key in the start position.
Tuesday morning I attempted to start and it was the same as the previous attempt. I noticed that the theft prevention appeared active (flashing) so I removed the key, locked the doors, unlocked the doors, tried again - no joy.
I kept trying while holding my mouth in different positions and finally by the grace of God it fired. I delivered it to the dealer.
The dealer called yesterday afternoon and reported that everything is a result of a bad trailer brake module. The new one is to arrive today, they will install and everything will be peachy.
I asked if they could just unplug it and reprogram the truck to believe it never had one - the service writer said it can't be done, different piece parts on trucks with or without trailer brakes.
I really have no choice but to push the "I believe" button and carry on but I am slightly concerned. The fact that the trailer brake module can cause catastrophic failure doesn't seem too cool, I don't have a real warm and fuzzy feeling associated with venturing far from pavement, reliable communication or alternative transportation.
In the meantime I suggest that no one take "trailer brake module failure" lightly.
Every time I touch the brakes I now get a very annoying beep and an error message that says "wiring fault on trailer." I don't have a trailer hooked up so not for sure what's going on. The error message on the console I can live with but that loud beeping is driving me crazy.
If you hit the brake and keep the pedal depressed, then you only get the initial beep and then it goes away. The problem for me is I live north of Dallas so if I'm in traffic then I'm constantly hitting the brakes. I called my dealer today so I'll wait to hear what they have to say.
I have a 2008 F450. What may be going on with my truck. In the past the truck would blow the fuse for the door locks. Currently the display is showing wiring fault with no trailer attached, the horn is not working and the cruise control has stopped working. I've covered the basics and checked all relays and fuses and haven't found a faulty one yet. I'm thinking bad ground or possibly bad GEM module???? I've read and read topics and am more confused as to what it could be now than when I started.
View 3 RepliesMy 2011 F350 is shaking like a wet dog, all the time, loaded with a trailer and empty. It's the whole truck, not just the front end or rear end. It'll shake a Dr Pepper flat in 10 mins. No one can figure out why. Maybe y'all can think of something.
Here's what we've done
New tires, balanced
Alignment
Replaced ball joints and sway bar
Replaced carrier bearing
Replaced passenger front hub that got mysteriously locked and henceforth destroyed.
Replaced all 4 shocks
Where to look next?? Guess I should mention is 4x4 dually with 177,803 miles.
I'm having some electronic problem with my 350. I parked it and took both batteries out for about a week. I put 2 brand new ones in and hooked them up truck won't start. So I turned key on and left on and the fault that comes up is the "trailer brake module fault" also the abs light, parking brake light & passenger airbag lights are on. Sometimes if I leave key on long enough the lights go away and I can start the truck. But it shuts down during idle. I unplugged the tbc (indash) and the #22 fuse under hood and #31# on passenger side. Still showing the fault. I'm not being allowed to start the truck. I used my tuner and found one code (P0884 tcm power input intermediate)..
View 14 RepliesBrought my truck (2012 F350) for recall service for one of the faulty exhaust temperature sensors. It took them one week to replace the sensor (!), then when I came to pick it up I got: "Trailer Brake Module Fault" message on the display.
I have never seen this message, since I own the truck (I am original owner). The service adviser said it will take a minute to reprogram the module and took the truck back to the shop. Came back after a while, saying that it didn't work and I need to leave the truck, so another technician can work on it tomorrow. Tomorrow came and I got the call that they reprogrammed the module, but the message still shows up, so they need to work on it (another day!).
As of now they still don't know what is going on. Apparently they broke something while replacing the EGT sensor and how to fix it.
It seems like recently almost every time I start my truck it beeps 5 beeps 5 times. so it beeps 25 times. what could this be and how do i get rid of it. I wear my seatbelt so it is not that. There has to be a relay or something to stop the dam thing from doing it.
View 14 RepliesHow does the truck know that there is a trailer connected?
With my cab-over camper and no trailer as soon as I go to reverse the back up alarm goes off. I thought I would wire in a marker light to the trailer brake circuit but that didn't do it, maybe not enough resistance? The truck still says no trailer.
How I can fool the system so that when I load the camper it looks like a trailer to the truck?
Well, it seems the cover on my trailer connector got broken off. The cover locks the trailer plug into the truck side. The connector on the truck is/was supplied by Ford. Now the dealer say NLA, only 2005 and up. Truck is 99 F250 SD. Plug is 4/7 way. Where can I locate a direct plug-in replacement? I do not want to be cutting and splicing.
View 14 RepliesI am looking at getting my new truck, my 05 F350 6.0, with factory trailer brake controller, all set up for a gooseneck. I was wondering if there was an OEM kit to add a trailer connection plug to the inside of the bed? If there is, what are the part number(s)?
View 9 RepliesNot working at plug.
I see there is right turn/stop relay.
Does this relay ever go bad?
All other trailer lights work.
Went to hook up my trailer today and both the trailer plugs do not work. I checked the fuses and all is well. They worked fine the other day but now they don't work at all. I confirmed this by hooking up to another trailer and nothing. Also got another truck and went to trailers and it worked.
My truck has 19000 miles so it's practically new. I have never seen this. I called dealer but they can't see it til next week and I need the trailer brakes and lights. Where could I look or what could the problem be?
The door on my trailer plug is broken. I can't seem to find just the door. Need to get one without having to buy the whole plug assembly?
View 6 RepliesSo the other weekend I hooked up to my buddys landscaping trailer, everything was fine until I plugged in the harness, No Lights...no big deal cuz it wasn't much of a drive, but I gotta haul a boat tomorrow a little ways and Id like to be legal.
I need cleaning my trailer plugs. What is the best way to clean the terminals on the small 4 prong? The big plug is fine, just a little dirt inside the cover, but I am still going to clean the contacts and put di-electric grease on them.
I've just bought a new 2016 SD xlt. The only extra I wanted that is missing is the factory trailer brake controller. The dealer told me it had to be programmed. I was expecting plug and play and planned to do it myself till they told me that. Is this true?
View 14 RepliesA week ago last Saturday I bought a 2006 F250 Lariat Crew Cab with the 6.0 and 4WD. The truck is really clean and only has 68,000 miles on it. Here's my question: I needed to tow a boat today and I discovered I have no power, at all, at the trailer light plug receptacle. Nothing at the 7-pin nor the flat-4. I looked through the manual and checked every fuse that had the word trailer associated with it and I can also feel the turn signal relays clicking with the flashers on.
Am I missing something really simple or do I just need to follow the wire harness from the back and look for something that is not connected? It seems kind of weird for it to be just....dead.
Have recently been getting a "TBC Fault" message and the Beep, as the message goes on and off(annoying) looked around think its the Controler itself,,If I move the slider, and Jiggle it,,the message Blinks on and off as I move the Slider,,,Looking for the method of removing it from the Cubby Hole,,,Gave it a tug,,,and wiggle did not move must have a Clip or Tab to release it.
View 8 RepliesThe pigtail from my bumper mounted 7-pin to the factory connector is all hacked up from the previous owner so I'm looking to replace that pigtail. Also wondering if there should be 2 connectors down there to add a connector for my gooseneck or do I need to splice another universal 7-pin into the bumper light pigtail? Also, is there another (preferably slightly cheaper) option besides e-trailer for such a connector?
View 3 RepliesThis past weekend I loaded up my 3 horses on my trailer and found out going down a hill that my trailer brakes aren't coming on and tracked this down to a problem with the truck. Need to troubleshoot this before taking it to a dealer to check wiring problems for shorts somewhere.
What doesn't work: trailer brakes not getting any power to the brakes. When I first pulled out the truck had error message popping up saying Trailer wiring fault and once in a while that would disappear then come back on and once or twice went to Trailer disconnected. My friends hooked up my trailer to their truck and the brakes worked on the trailer.
What's working: turn signals and brake lights coming on in the trailer.
What we checked so far: fuses, sprayed truck plug with wd40 on the pins. The brake pedal not activating the brakes and tried just the slider bar on the ford integrated brake control box.
Background: brakes were working fine back in October. December hauled them a short distance and didn't notice any braking problem but road was mainly flat and when coming down a small grade they seemed fine but I was going slow also. Back in January, I took the truck to a Firestone to get general maintenance work done on it including truck brakes checked for wear and tear and they had to replace the truck battery.
Where does the truck ground wire go to in the truck to ground it out? All that I can find is that it has to go to some pure metal, no painted surface but can't find anywhere on where to check this out on the truck to see if it is still making contact. Could the guys at Firestone have not hooked something back up or knocked it. The last thing that I would like to look at before getting the wires all tested. I have a 2008 F250, gas
I have a 2002 F350 7.3 Powerstroke with approximately 200,000 miles. Recently I have been having an issue with what I am told is my airbag control module heating up to the point it is too warm to touch when I am pulling a heavier load. It is located just under the dash on the center hump. I removed the black plastic cover revealing the module itself in order to determine that indeed is where the heat and smell of hot electrical equipment is originating from. It gets too hot to touch when pulling a heavy load and making the motor work...once I lighten up on it or am not pulling it immediately cools back down. If it is an option I would just disconnect it but I havent yet for fear of creating more of a problem.
