For the first time yesterday the wheels spun (on purpose) with the control off it still kicked in? can this be tuned out? and why did it come on? sorry if this post is in the wrong place.

It's not like you can actually feel it. Here is a good test though. Push the button, yank up the E brake handle and do a nice burnout. Do both tires spin or just one? Does it feel a little like something is fighting you to get going at first but once they are spinning it's no problem?P-51 said:
You don't understand that the Ivd is not there to limit the front wheels from spinning when you have the button off. It's just there to act as positraction in a straight line acceleration. It keeps the right and left wheel going the same speed by braking slightly. It does not slow the car down. It can cause a brief hesitation at first to try equalize wheel speed but that is about it.
It's a fact. You may not realize the car is doing it, but it does it.
I know someone else was talking about this but I would just like to put this out there: I asked my father (electrical engineer of sorts) to design a very simple in-line circuit for me that will automatically turn off TC when the car is started via a simulated button push. The TC can then be turned back on if desired but the circuit will make the system default to OFF.
I will post full design details when I get this thing. I expect I'll probably have it in hand by the first of the year.

I was reading the owner's manual for my 2007 ZX5 SES (which comes with Advance Trac) and it says that even when the TCS is disabled via the center console button, it will still kick in below 45 MPH. It doesn't say by which system this will happen (engine retard, brakes or both), but it says it will still intervene. I'll check the page number tomorrow.
As I'm still breaking in the engine, I've been reluctant to try it out (much). :lol:

Hey, I happen to be a Ford sales rep. here at Sanger Ford and I am on my second focus ZX-3 now.. I had a 01 ZX-3 and now a 06 ZX-3 with the street appearence body kit.. One thing they make us do is take tests on the products.. Here is the thing with the trac. control on these later model focus's.. The trac control even when off still works up to 25 miles an hour.. Give or take.. So yo9ur stuck with that,, but I will find a way to bypass this... I am gonna have one of the tecs assist me in this... Maybe we can make a toggle switch to completely turn the system off... All you guys keep me informed as well.Steveamtb said:
Ford engineer here... just thought I'd chime in with some confirmed information. Yes, in fact, brake-assist TC is still enabled under 25 mph at all times. It is very subtle under most circumstances... I can barely discern its operation most of the time. In normal mode, by the time you feel the engine cut, the brakes have long since (relatively) been trying to control wheel spin. :thumbup:

I think everyone ignored the fact that I posted a scan of the page right out of the owners manual... lol

I got it; it's a beautiful scan, I must say. Thanks for that, btw...
I don't have Traction Control or ABS, so I've kept quiet during this thread until now.
Anyone get the part about leaving the TC button depressed for one full second in order to switch it on and/or off?
I'm an advanced & manufacturing engineer for Ford Motor Company, North America. In a nut-shell, I work closely with all of the North American Ford assembly plants, Ford's suppliers, Ford's machine vendors, Ford's skilled and unskilled workers, and consult with nearly every other branch of engineering within the company... ultimately to ensure we CAN and DO produce "the product" in a "correct" and "profitable" manner from the very moment the product begins life as a conceptual design on paper ('er computer more likely) to the moment its rolling off the assembly line.pzev04boy said:
Traction Control: My Very Unique Point of View
Here guys need to understand that The TC changed after 2005, the advance trac(the older system was using brakes, And the new one does not..)
Read the entire thread before you post...
on a 99 mustang the trac control enables brakes to help, and then on a 2004 mustang it only cuts the motor.. there has been an evolution for mustangs and there has been one on the focus!

lol, I think the ford engineer knows more than we do
I'm not trying to stir the nest on this one, but quoted directly from my 2007 Owner's Manual, page 134 (near the bottom):
At speeds below 53 MPH (85 KM/H), both the engine and the brake system will be used to control wheel spin; at speeds above 53 MPH (85 KM/H) only engine torque reduction is used. When the TCS is switched off, the braking system will still be used to control wheel spin at speeds below 25 MPH (40 KM/H).
The sales guy also made a point of illustrating the dual portions of the TCS to me in his pitch.

This is great, at first i thought it was not the greatest of questions. But this has made some great reading, then throw in the Ford guy. Down the road this could be great for us Focus people. Humm hay Ford how about the Mazda 3 speed turbo motor in the sedan, how about it! Nice 6 speed tranny also
