I have a 2012 Silverado The traction control will turn off but light does not come off in the dash what might be wrong? And when traction control is on and I spin the tires Traction control will kick in but the light does not come on in the Dash then either. Ps I just got the truck three months ago they did some Things to the truck to hide some things. the papers said 185,000 but the dash only read 131k I don’t know if they change the dash.
