TCS Wont Turn on or off . Bet no one can figuer this one out.help me fix my TCS

[guimond47]

Alright. first off. i ended up having the TCS OFF light on as well as the abs light. i checked it with and abs scanner and the scanner would pick up and error code that it couldnt comunicate with the abs moduel. i swaped out the abs moduel and abs light is now off. when i first started the car the abs light would be OFF but the the TCS OFF light would come on by default. this isent normal. usually when u start the car the TCS light is off( not lit up) which idicate that TC IS ON by default. well okay. soo i press the TCS button to turn ON the TC since the light ( TCS OFF ) appeard on when i started the car and it turned off the light. i would think that my TC is now on but it isent. i can still rip the tires on it no problem. i let it be for a few days and one day when i started the car the light TCS OFF dint appear soo i tought okay its all back to normal but no. now when i press the TCS button NOTHING happends, the light dosent turn on or off. its like i have a button that does nothing. when i rip the tire the Low TRAC light still appears but the TC system dosent engage. this is ridiculus.

and guys dont post " who needs TC" its not the fact of who needs it , its the fact that i want it fonctional. and not a broken device. if anyone has any info on th TC system it would be nice. thanks

Maybe from tcs off light being on all the time it burnt out, and your problem still exist

There is a ground under the air box on the driver side of the car. It is just mounted to the metal of the car. It is the ground for the ABS module. I had mine go out which would cause the non communication (No ABS or TCS) because it has not ground so it won't turn on. I would check that ground wire first. Make sure it has a good, non rusted, connection.

The other thing I would do after you check that wire is to just disconnect the battery and leave it off for a couple of hours. It might possibly reset everything.

X2, It won't let you turn the TCS on when there's an ABS issue.
