What does light TC mean

Hello, most likely the TC indicator indicates "Traction Control". And it could be that it's shut off, or it could indicate a fault has been detected. Check for a Traction Control button on the dash - often it can be turned on and off. Try that first. Testing will be needed; diagnostic trouble codes for Chassis related (C) codes will be set if there's a fault in the traction control - and/or related antilock brake system areas.
