Some type of electrical problem....could be in the dash, the light, or the wiring to it.

The TC system is basically a go/no go system when it comes to the light.....it will either flash when it senses a loss of traction, come on when the system is shut off or has a problem, or stay off when there's no problem at all. There's no provision for the light to come on "partially" other than a electrical gremlin.
