I have a 2016 F350 crewcab longbed. When the wheels are turned and your going over bumps it sounds like the abs or traction control turns on, but nothing lights up on the dash. I took it to the dealer they said they could not get it to do it. Funny since it does it anytime the wheels are turned gong over bumps. Feels like the abs is coming on. Any ideas? thanks

Well, since the dealership technician cant duplicate your concern, the next logical step is to take one for a road test and demonstrate it for them if possible. I have been on many a road test with vehicle owners over the years and sometimes this is absolutely necessary. My thinking is that the truck is probably doing what it is supposed to be doing for the driving conditions you are subjecting it to.

With that said, you could do a little research on your own. If this concern happens and you are NOT BRAKING it is not likely an anti-lock activation event though a sensor signal dropping out could cause false ABS activation. Read on... I am thinking you are probably experiencing a Roll Stability Control (RSC) event or traction control activation. The traction control system with RSC aids in the prevention of excessive wheel spin, which allows the vehicle to maintain traction during acceleration especially on slippery or uneven road surfaces. This is accomplished by using the PCM to modulate engine torque and the ABS module to cycle the vehicle brakes. Both the PCM and ABS modules work to reduce drive wheel spin by momentarily reducing engine speed and applying vehicle brakes. You could turn off this feature (consult your Owner's Guide in the glove box) and drive in the same place where you know you can duplicate the concern and see if anything different happens.

You should also be aware that modifications to the vehicle such as larger tires than it was built with and suspension lift kits can adversely affect the proper operation of the RSC system. I am not making accusations, just putting that out here as we have no information about your truck in your signature and I wanted to make sure I covered that possibility as well.

Wow!! ford_doctor ..... who needs to spend hours at a dealership when you're on this forum, XLNT info for the OP. On that note, I've read other owners complaining about bad fuel mileage and were told that it might be the traction control causing the ABS or something of that nature to slow the veh. down just enough to cause the mileage problem. I would think that if the pads were rubbing on the rotors even just a little you would smell the brakes or something would gain your attention....don't know. I'm very interested in this along with the few other Superduty glitches as I'll be ordering a 2016 F350 dually very soon. Thank you very much for all your input and advice to all of the members.........Dave

Wierd....just noticed the time of my posting says "09:39 PM" which isn't possible, 09:39 is AM ....2139 is PM, gues whomever set this up wasn't a cop or in the military.

IIRC, you can set the "time zone" in the control panel and 12 or 24 hr clock,so you could post today and have it say tomorrow.

I get that too on a sweeping left turn that I always take there is a few bumps and I don't know if its from the turning or the acceleration through the turning but I feel the engagement of the system. just some slight wheel hop from the bumps either rear spinning faster than front or front slowing compared to rear. life of overly complicated stability systems and 3/4 and 1 ton stiff suspensions. thanks to people that can't control wheel spin and sliding sideways.

It happens with my 15 as well, certain sweeping right hand turn with frost heaves in the road nearly every morning.

So not having the new truck yet....and my old '02 7.3 has nothing which I like, can you turn off the traction control function?

There is a button on the dash and the Owner's Manual covers how to enable/disable this functionality.

09:39 PM or AM is correct depending on the time of day for common folk.

0939 would be correct for military/law enforcement in the morning, not 09:39. Hence the " : " is removed....if you are going to complain get it right.

I doubt very much that the traction control and RSC system would affect fuel economy at all because these systems are active very infrequently on a momentary basis.

So is ford working on fix or just blowing it off . it should not to be active at low stabile speed coasting no brakes applied condition . I have 2016 f 250 4x4 now lifted but it did it bone stock as well still stock tires and rims . to me it seem to be a program issue . any more input or any one come up with fix rather then bypass ?
