I would say - due to the registration date of your 172 - that you dont in fact have traction control.
The traction control system fitting to later model 172s and to 182s etc is activated everytime you start the car, and to disable it you have to push a button which is down on the right hand side of the steering wheel next to the thumb wheel which changes the level of the dash lights etc, if you dont have this AND you can wheel spin the car then you dont have traction control.
(Some Dutch imports did have traction control but no button, but they were constantly on, and you would have noticed if the car had it in that case)
