Traction Control issues after tire repair

[jsherwood275]

Had a flat today on my 25 ST due to picking up a screw (and not the good kind. ). Drove 2 miles on the donut to the shop and they repaired the tire and remounted to the car. Upon leaving once I hit 35mph the traction control light comes on indicating slippage (completely dry day) and reduces engine power. Stopped the car and tried again...same issue, so I go back to shop and they check via the scanner and no codes. If we turned off traction control it allows you to exceed 35, but as soon as you let off the gas the car tries to reduce power by downshifting quick. I hope it is software related and not a transmission issue after only 3000 miles. Needless to say, it is being towed to Ford!

I think there was another thread on almost this same thing about driving on the donut. Doubt Ford changed the design/size of the spare for the '25. Normally the issue pops up as soon as you drive on the donut. AWD turns off, etc. and then goes back to normal after a little driving. Unless the '25 requires you to 'tell the car' somehow that all is good again. Maybe another key cycle or some slow driving to see the tpms or something will clear it out?

If that is the case then Ford needs to manage this better. Not able to drive faster then 30 miles and hope the system resets is BS. At least make the spare the same diameter as the normal tires to prevent the system from getting confused. The car was cycled at least 4 times and driven a few miles around town. There is also no setting anywhere to reset tire size and no codes or settings in the scanner.

TPMS system is working fine. All show the correct pressure once the tire was remounted. Issue is with the traction control.

Front or rear tire?

Front

EDIT: just say your post about tire pressures being correct so i'll delete that.



Just trying to think of reasons why the system would think it's detecting wheel spin. Without codes present that would suggest it's actually seeing 1 wheel spin faster than the others.

Shop did put the correct tire back on right? Same size? Just crossing that off the list.

Short of that i'd probably quickly inspect the ABS wheel sensor and exciter ring on the axle and make sure those are clean. Grease in the ring collecting metal might trigger false readings. Could be an unrelated, coincidental issue to the flat tire. But then again i think the tire shop would have noticed that.


Double edit: When they say no codes, are they scanning the modules for DTC history? ABS/TC modules aren't easily read by standard OBD scan tools. Need a professional tool or ForScan. I'm assuming they have a better scan tool that can do this, but that's an assumption.
