traction control

my 95 RR TC light stay on.what to start looking that frist?
thanks

TC works only on the rear axle, so I'd check the air gap on the rear sensors first.

as of right now the light turn off.so will have to wait and see now?

light back on!
i can't find anything about the TC in my manual i got from RN.that let me know what to look for are how to test it?
and what it the air gap on the rear sensors at?
