If you know anyone with a scanner for OBII have them run a scan, most parts stores will lone one or do a scan for free.

I think the traction control light is only supposed to come on when the system is off, or is it on, I forget now.

There should be a switch on the dash that turns the system on and off. Try switching it on, then off and see if the light goes out.

The only time I remember the light coming on in the one I drove was when I spun the wheels trying to get across a busy intersection. It stop the wheel spin as soon as it started, and the light came on then.

But then it was someone else’s car, I was driving.

 

Traction control should only come on when the wheels spin and the traction control engages, although I recall driving a grand-am rental where the light was on if the button was pressed so that the system was on.

I agree with Fiero, try pushing the button to turn TCS off, and see if the light goes out.
The ABS light shouldn't be on at all unless there is a problem.
That dealer is inept. Tell your friend to go to another dealer.
Ignoring the ABS light can lead to ABS malfunction including loss of brake power.

 

I beleive from what I found out so far that the ABS light only comes on when they need service NOT if they have been activated. So get your butt in there before something bad happens. Patrick is right it seems ABS wheel sensor fail is not a comdition you want to drive around in.

My work van is in shop for same condition as we speak...
