What does it mean when the TCS light comes on? What should one do?
Your traction control system has stored a fault and that is what triggered the light to come on.You will have to have the codes read before any diagnosis can be done because you need to know what the computer is seeing to set the fault. Most common are wheel speed sensors but without fault codes it is impossible to say for certain. The vehicle should still drive and run normal with the exception of the traction system being offline.
