I got my TCS light on, can't reset it, tried to unplug the battery for few min then plug it back, the light still there. I don't know whats wrong. Can anyone help with this problem, any opinion would be appreciated.

 

Is your Check Engine Light on?

Were your driving your car aggressively (heavy braking) when the light appeared?

Is your transmission showing any signs of failure (slippage, delays, erratic shifts, etc)?

 

I recently changed ABS modulator, Transmission too. The story is that the TCS light was on even before changing all that crap. Sometimes in the morning and actually during the day, when I start the car, and change gear from parking to whatever reverse or drive, something kicks really hard it even shakes the car, D5 start to flash, and car won't change gears, only from first to second. The funny thin that this shit is still happening after I changed the tranny. So, when the D5 start to flash check engine light come out. The funny thing is that if I reset everything( unplug the positive from battery for couple of minutes) everything becomes normal again,I mean no check engine light, and tranny works fine, but the frikin TCS light is there no matter what. Now, I described this exactly how it happen all the times, about twice a week I have to go thru reset process. Can anyone reffering to what I just described tell me what the hell is going on???????????? My idea that is ECU, but maybe I am wrong. Appreciate any help!!

 

I have a strong guess for the ECU too because the symptomes you are describing come from a tranny thats about to die but you allready changed that. The only thing left is the ECU is having trouble with the new tranny?? I think they just repaired your tranny instead of giving you a new one. Look into the tranny issue first then ECU. By the way which body kit is that...its pretty hot.
