I've got an intermittent Trailer Wiring Error message that started appearing with a trailer connected on my '11 F250.
Brakes and lights work OK on the trailer, I thought I had read on the board here that there was a TSB for this, but I cannot find it.
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.
Driving the truck today I noticed mssg from info on dash " problem with trailer wiring". I wasn't hauling anything. the message went away on my next stop when a truck was turned off. On my next stop, I was pulling into a parking space truck stalled and I saw another message saying something like " please pull over safely and stop a truck." Luckily I was already parked. the truck would not start or even turn over. after about an hour truck started but brake symbol was on the dash.
View 10 RepliesI have (2) 2014 f250's both have given the trailer disconnected message randomly from the day they were new. Dealer says everything is with in specification. I just live with it now but something must be wrong with the design. Only does it when no trailer is connected an might be worse when it rains. Might have to hit the ok button every 10 minutes so on bad days.
View 14 RepliesMy 08, when I connect my 7-pin trailer up, bouncing down the road that message and tone CONSTANTLY going off....drives me nuts! I have went thru the wire harness 2x now, cleaned all the contacts, etc. Any other thing short of a 12 gauge? When it does pop on, the controller starts flashing...I've reached down a few times and manually hit the brakes and it still hits em so whatever it is, I feel its very minor or whatever....just don't know where to go now! All contacts have been cleaned good as well.

Just picked up my F250 a few days ago and it's been great up until yesterday when I hopped in to start her up and nothing. It's a brand new battery and all lights worked, but the dash was dead. I attempted in vain for an hour or so to diagnose as to why this was happening and just happened to open the door with the key in the ignition and hit the door lock button....all of a sudden the truck starts beeping and the message on the dash said "to disable alarm start vehicle". I turned the key, the dash lighted up and away I went. What I may have done to cause this or has it happened to you? I'm thinking it's something with the key fob but not sure.
View 6 RepliesI recently purchased a 2011 F550 Super Duty with a flatbed mounted on it. Turns out, the trailer wiring harness is totally screwed up and I am getting tons of shorts whenever it rains. Going through it front to back, we are finding multiple problems like missing fuse box covers, damaged fuses for starters. The Ford dealership in Texas that did my prepurchase inspection for me totally missed all of this, so i am stuck holding the short end.
IN the rear of the truck we detected shorts in several areas. One of them is in this adapter pictured along with this. Is this a Ford part, or does it appear aftermarket? Is it just an adapter or is it more than that? I am just now getting to l know this truck more specifically. given the date of manufacture on the label it would seem to be from Ford??? Part # is 99-004 and 71-012-A...
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 RepliesI have a 2005 Ford F-250. I have checked power to the rear harness and all is good except for the tail/running lights.
Is there a fuse for the tail lights? I have checked the manual and don't see one called out. And the relays under the hood are labeled stop lights/turn signals and those are working fine.
I will see if I can trace the brown wire from the rear harness backwards, but it may be a simple fuse.
Any info if the "Aux" terminal on the trailer harness wiring on '01 F250s is for reverse lighting? I'd like to put some on my stock trailer. Also, is the "12v" terminal feed switch operated or hot always?
View 2 RepliesI have a 2005 ford f250 with the factory installed brake controller and towing package,until recently all was well,I tow a fairly large travel trailer and last time I hooked the trailer to the truck I noticed the running lights on the trailer were lit, I checked to make sure that I did not have the parking lights turned on or the headlights. I did find posts about the running lights not working and was surprised to find there is a relay somewhere on the central junction fuse block that was integral to the cfb and not user serviceable. Could my problem be that this relay failed in the closed position or am I not going in the right direction in my quest to find this problem. Also looking for a diagram of where this relay is located on the central junction fuse block? I would also consider doing a work around solution rather than having to replace the entire fuse block.

View 1 RepliesSo the other day 2/3/2014 my dad and I went out during the snow storm for the people that needed assistance. That day I pulled a 95' RWD dually with a 4 car open trailer and pushed 4 people from one location. Then after I went to assist the tractor trailer driver. My truck is a 2002 F250 super duty 5.4L with 4:10 gears. I got him unstuck then pulled him a 1/2 mile up a hill.

I tow a 5th wheel with my 2014 F-250 that has an factory TBC. I just installed Electric over Hydraulic disc brakes on my 5th wheel and was trying to see if there was a setting I needed to change on the TBC to tell it that is now E/H versus E. In the Information section of the dashboard display it talks about the controller actuating electric drum brakes but the manual talks about it being able to do electric AND E/H. What I need to do here...if anything?

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.
My husband and I bought a 09 f-250 with 58000 miles. It used to pull our travel trailer with no power issues. Now the rpms go up & the power goes down. It never gets hot nor any lights come on. It's been in the shop twice. The first time nothing was found. The second time we were told it was dirty fuel filters. The truck only has 70k miles...
View 2 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.
My 99 f250 ran hot while towing my travel trailer when the fan clutch gave up. ever since iv been noticing coolant loss and pressure in the day tank.ive changed the water pump,radiator. day tank and cap plus the thermostat.
View 9 RepliesI have a 2006 f250 superduty crew cab longbed with the v10 gas motor. it has 201000 miles on it and towed great up until last month. I was towing a 5000lb trailer down the interstate at around 68mph,suddenly it was like the drive train disengaged and the motor had nothing left, check engine light on but no overheat condition or lack of oil pressure. we put a new fuel filter and pump on and maf, took trailer out again and same problem, pulled to the side and turned off, immediately restarted and ran fine. It has a cat not cleaning code in it now!
