Stabilitrack warning light on

[spikesputnik]

Last month I spun the tires a little pulling into traffic, and the traction control and ABS lights come on in the dash.  I tried to reset it by disconnecting the battery to no avail.  Everything runs and sounds fine otherwise for a truck with 100K on it.  So now its at the dealer to look into it, as well as replace the airbag, finally.  09 Silverado 5.3 2WD   fwiw

 

Question- does traction control function have anything to do with the TCM? Or ECM?   The reason I ask is when the truck was nearly new I had the AFM programmed out of it and a tune done on the TCM and don't want to loose those tunes!  Are they likely to want or need to mess with those modules?

Thanks

The ABS/Stabilitrak lights are only with the ABS module. The TCM or PCM won't set a ABS light.

Thanks CamGTP, that’s a relief.   I’d heard of bad problems after reactivating the AFM after years of inactivation.

Turns out it was a wheel speed sensor failure.  $475 repair

I figured as much. Taking it to the dealership is likely the most expensive place to take it as well.

True, but it had to be there for airbag recall, so figured just let them.
