    In a "normal" Prius, there is no designed-in way to disable the Traction Control. It is always enabled and not operator selectable. You will need to have the system inspected by a qualified mechanic. Hopefully, it is only a fuse/circuit breaker?

    It may be a damaged wheel rotation sensor. If a mechanic is not careful they can rip the cable out of the sensor.

    I have the same issue with my 2010. After replacing a blown fuse in the cabin fuse box, the light came on constantly, cannot detect any codes and will not reset. How do I get rid of the light?

    Reading the diagnostic codes with Techstream is the simplest way to find out what the issue is, if you have it.

    If you do not have it, counting the blink codes after jumpering the Tc and CG terminals will be the next easiest way, and only requires a short piece of wire.

    Yeah, chances are it's indicating a fault, not that the TC was purposely disabled. Best to get it checked out and see what's up.

    When you turn the car ON with those pins jumpered, many lights on the dash will start blinking. Traction control is a function of the "skid ECU", which is responsible for the ABS light, the brake or ((!)) light, and the VSC or swervy-car light, so watch all three of those. Be sure to make note of which light blinked which codes, because they are on different lists in the repair manual and mean different things.

    Other lights on the dash, associated with other ECUs, will also blink. Any steady fast blink just means that ECU hasn't got anything to complain about. Otherwise, you can write those codes down too. They won't be related to the traction control, but might be of interest anyway.
