Well... like many people here every once in a while you hafta cut loose in your TL :-D Admit it. Well, if you cut loose in yoru TL on wet pavement you will notice that your car dies down bc of the TCS. Wat i think the TCS is, is a second throttle boddy infront of the one connected to yoru gas pedal. iam came to this conclusion wen i took apart the plastic housing part and noticed there were 2 wires near throttle body and taht they seem to be connected to two different things... iam not sure and i have no idea wat it is. BUTTT is there a way to shut off TCS ? bc you cant pull the fuse becuase its the same fuse that goes to to ECU -_-
