'TCS Off' light comes on randomly
'TCS Off' light comes on randomly Im having a problem where ill just be driving and the 'TCS Off' light will illuminate on my dash. If i hit the TCS Off button, it will not always go away; most of the time it will just go away itself. What the hell can possibly be going wrong? Bad sensor somewhere? bad ground?
ive been using the same size tires since i owned the car (2.5 years) and have never had a problem until recently.
Sometimes the 'TCS Off' light will come on for 2 sec then go away. Sometimes itll stay on for 60 sec and wont go off until i hit the TCS off button. Sometime itll stay on for 60 sec and wont go off, even if i hit the TCS off button..and then itll turn off 30 sec later. The TCS button and the wiring behind it seem to be fine. I just ordered a new TPS switch; ill see if that does anything

Is your 'e-brake- and 'Abs' light coming too? If so, I think it's your ABS module that's connected to the distribution block. If only the TCS light is coming on, then it's something directly related to only that.

ok 01 ss vert just stated my problem exactly. Ive only really started digging into this problem.... but you said the ABS module is bad. Isnt that all one peace that requires all the brake lines to be taken off or is this something different(seperate)?

Mine started doing that after I put my new rear end with w/ 3.73s. So maybe the same concept applies here. I posted this a while back and never did get any definitive advise on it. Hopefully this thread will be more productive.
Be sure to pick up a unit exactly like your car (3 or 4 channel ABS, with traction control, not sure if transmission matters or not). I posted a 'wanted' ad and bought a used one within an hour of posting. took about an hour to swap units, and that was becuase one of the 6 allen screws was stripped.
When this first happened, I thought it was a wheel speed sensor, but upon further research, and testing all the sensors, it was the module. Not sure what a new one runs, but I got mine for $55 shipped, used.
Hope that helps! PM if you need more info. Rather straight forward and easy to get to.
Im pretty sure i fixed the problem. Just replaced the TPS sensor and the OPSU (thats a different story). I rook the TA for a 30 min drive and the "TCS Off" light didnt come on randomly at all; normally, it would happen once every 3-4 min. hopefully i settled the problem once and for all ::knock on wood::
cruise control still doesnt work, but thats not been working for over a year. i could care less if it was working anyway, i think i used it once in the 2.5 years ive owned it
