You can disable it with a handheld tuner.

I wonder if this has been done before. Is your traction control actually on?

Did they check the switch itself ?
Does the light on the swith light up at all (Off)
My GT did the same thing when I first bought it.
Replaced switch and problem was fixed.


Yes ..as Moonshine stated a hand held tuner like a SCT will turn it off for good

The t/c switch and indicator LED connect to the instrument cluster, which then communicates with the ABS module via the SCP (Serial Communications Protocol, OBD2) bus.



The instrument cluster senses that the t/c button has been pressed and passes that information to the ABS module as a data packet. The ABS module then toggles the state of the traction control; I.e. if it was on it shuts it off and if it was off it turns it on.

The ABS module next sends a data packet to the instrument cluster telling it to turn the indicator LED on or off.

You can see that the instrument cluster is in the middle, it may be an issue therein. If t/c was disabled in the tune the indicator LED would be on continuously (assuming it's not defective).

Here's a link to a post I made earlier this year as to how to test the t/c switch LEDs...

Not a good way to start on this forum... with 2 post.
CliffyK happens to know his Mustangs very well.
I suggest you learn to know people on here before you talk about someone trying to help you.
Maybe you should get to know Bladerunner.

Showing disrespect and attitude toward guys that almost run this site will not get you an answer. Calm down, everyone has problems. Relax and in time these guys will help you figure it out.

Did this just spring up out of the blue, or after something (anything) had been changed? Did it ever work?

Was any work done on the electrical system, anywhere in the system, without the battery being disconnected? HF arc welding of the chassis or exhaust system has been known to create problems if the welder's ground is not connected to/near the component being welded.

As I said above it is the instrument cluster micro-controller that actually switches the indicator lamp, have there been any recent i/c issues?

If the problem is in the communication between the ABS module and the cluster then whoever tracks down the issue will have to have, and know how to use, Ford's IDS (Integrated Diagnostic System)--this is most likely to be a Ford dealer.
