MY SERCVICE LIGHT IS ON HOW I FIX IT
JUST BOUGHT THE CAR N I SEND IT TO THE REPAIR SHOP WHEN I PULLED OUT
OF THE MECHANIC SHOP THE SERVICE LIGHT CAME BACK ON WHAT CAUSE IT
Many different things. Since the light is on, you can scan your Vehicle for the code that is causing the light to illuminate. Take it back to the shop since you just bought it and have them repair it, not just clear the code as it will just come back on.
Take it back to the shop and demand that they fix it if you paid to have it fixed. They probably forgot to plug something in or didn't really repair your vehicle. Most likely the latter.
