They're having a factory technician fly out next week to try to fix it.

This post saved me lots of time and money!

Got the Hill Descent Error and Advance Trac Error intermittently for a few days, then eventually both errors stayed on solid.
Took the truck (2013 F-250 SD 6.7 4WD) to a local repair shop. The owner said that all of his references/guides pointed to replacing a module (can't remember which one but parts and labor $1200) - but he wasn't confident that would fix it. His scan tool showed all the sensors working correctly. He recommended performing a reset of the module and perform a test drive. During the test drive the errors returned. As a note - during the test drive he confirmed that ABS was working.

I decided that I was going to pick it up from the shop and continue to drive the vehicle then run it until something really broke (or possibly take it to a local dealer) . My wife did a search and found this thread while driving to pick up the vehicle. Once I got home with it I performed the procedure described in the photo.

1. Turned the key off.

2. Exercised the connection: I did not pull the connection apart - I only exercised the lever fully in both directions about 5 or 6 times. About mid to 3/4 stroke - I felt like I could feel when the pin contacts released and also resistance when the the pins made contact with each other. The actuation was smooth and there wasn't any binding or excessive force, so I decided not to pull it completely apart and try to inspect the pins - because there really wasn't much room to work!

3. Turned key on. Errors cleared!!

It's only been two days, but I'm hoping this fix holds for a while.

I really appreciate the shop didn't try to convince me to replace the module.

Just a thought: I found the lever latched in and the two connectors appeared to be pressed tightly together by the mechanism, so it doesn't seem that vibration caused loosening of the connectors. I guess it could be possible there's a weak crimp, weak male pin to female pin connection, or possibly a film of corrosion on the pin connections.

Newtonwb,

This entire post would have saved me hundreds (if not thousands), but I got lucky and my mechanic figured out the issue (same symptoms as all of you guys on here, pretty much) at the same time that I did. When I called him to describe my findings from this post, he proceeded to explain to me the problem and the fix, which concurred with your ongoing issues almost to a 'T'. It took him 15 minutes to assess and repair (he is an unusually gifted and talented mechanic).

If you continue to have issues Newtonwb, check the actual pedal adjustment. This adjustment is needed even if you didn't even touch the pedal to begin with. In addition to re-plugging in the brake light switch, of course, re-adjusting the brake pedal is what truly solved my problem.

Below is a synopsis for others

Background of problem: had dash removed to replace AC condenser. Brake light switch was disconnected and reconnected during dash removal and reinstall. Nothing else with the braking system was touched.

Symptoms: Brake pedal felt very touchy immediately. Intermittent wobbly stops. Intermittent brake grabbing that was only reversed by turning off the truck, applying pressure to the pedal, and turning the truck back on. Advancetrac and Hill Descent Control warning lights came on and truck went into limp-mode.

Repair: Checked, disconnected, and reconnected brake light switch. Pulled the brake pedal forward (this was the key repair, as simple as it sounds). The pedal has to be adjusted properly anytime the brake light switch is disconnected.

I checked another post about brake light switches where a specialist described that when disconnecting and reconnecting the brake light switch on some vehicles (including the F250), the brake pedal itself must be readjusted. If it is not readjusted, traction control, stability control, and the ABS system will malfunction. Additionally, for reasons beyond my comprehension, the brake pedal can get displaced as soon as you turn on the car, as your ABS/traction control system is improperly boosting it (or something like that). You'll notice it feels different right away.

Summary for future F250 owners with this issue: When disconnecting and reconnecting the brake light switch under the dash on the drivers side near the e-brake, the brake pedal must be adjusted properly, even if it was never touched to begin with. Due to the highly sophisticated AdvanceTrac system on the F250, if the brake pedal is not adjusted after reconnecting the brake light switch, you will have braking malfunction and possibly even transmission or engine malfunction (not being able to shift out of park or not being able to start the truck). Apparently, this engine turnover issue is due to AdvanceTrac disabling you from driving because it is not safe until the brake pedal is adjusted.

Advance trac messages

First post: People ask where this connector is that needs addressed. Pictures are shown, its talked about, ebrake bracket is mentioned, but no one actually confirms its under the truck, the seat, the dash? Com'on people answer the question that has been asked a number of times over the years through a number of threads. Where exactly is the connector that has to be pulled, cleaned, lubed and checked for solid contact with the pins? No I have no problem with getting to the point.

If you pay attention to the pics in post 32 above, you should notice the parking brake pedal assembly with the large grey plug above and slightly behind it, directly next to the driver's side kick panel. There is a lever on the plug that locks the two sides of the plug together. Pull the lever away from the plug to loosen the plug to take it apart to do your checks, or just unlock the lever, squeeze the plug by hand and relatch the lever. It has also been spelled out in quite a few of the other threads over the years.

Ok but wrong

No it hasn't I've read them over and over and its always never straight to mention the location on the vehicle. When someone mentions ebrake bracket that could be anywhere along the wires that support the brake system. A picture does nothing for vehicle location if its a close-up.

Well, since I have personally replied in several of those threads. I can say that the location HAS been identified pretty routinely - including the pics above in this thread by another member - which is EXACTLY what you will see if and when you look above the parking brake assembly. Take a flashlight and look above your parking brake assembly against the kick panel and you should see the plug. It's pretty easy to see when you look with a light. Notice in the pic above, the approximate location of the parking brake cable where it attaches to the pedal assembly. Notice also the green circle in the pics. Look for a black plug with a huge amount of wires running into both sides, with a grey lever in the middle. The plug is maybe 2.5" to 3" by 1" or so.

PS: Many of us on here like to have fun with our posts and come across as smart-azz's on occasion, and don't wear our feelings on our sleeves. Most of us also really enjoy being able to help others with issues they are having - if we have help to offer. Before coming across as a jerk, let people get to know you a little first, rather than starting your first post as a member coming across like that. You may "have no problem getting to the point", but it isn't the best way to get people to want to offer help.

To add to what EO2SeaBee said:

It's inside the cab on the driver's side.

With the driver's seat moved as far towards the back as possible it was still hard for me to get into a comfortable position to work on this.

Hopefully this image will help with the location...

"Brake Lever" probably would be better described as "Emergency Brake Lever" or "Parking Brake Lever"

The part circled in green is mounted on the top part of parking brake bracket. See close-up in post 32.

Note: I have not had the "messages" return yet (47 days).
