TCS is Traction Control System,and all TCS's are controlled though the Anti Lock Braking (ABS) system.Here's how it works:Each wheel,or in some cases,only the drive wheels have a speed sensor mounted near the hub or axle,and sends a speed signal to the PCM (Powertrain Control Module).The PCM monitors wheel speed continuously,and if it sees a speed out of the ordinary,say for example the right rear tire is spinning and traveling at a much higher speed than the left rear,the PCM will pulse the brakes through the ABS system on the right rear to slow down the right rear so that the left and right wheel speeds match up,this is how the traction control works.So,if you have a TCS problem,the PCM will see this and set a Dignostic Trouble Code (DTC).You need to pull the DTC's out of the system with a scan tool,diagnose and repair the DTC's.It could likely be something as simple as a malfunctioning wheel speed sensor,but you won't know until the codes are pulled out,as this will point in the general direction.Good luck.

SOURCE: TCS, SLIP and ABS lights on
Check your brake fluid first. If that is low, top it off and recheck. If its ok, than you will need one of the rear ABS sensors. You will need to plug it in and find out which side it is. That's really the only ABS issue that car has. One of the rear ABS sensors fails.

Sounds like the car is stuck in fail safe mode, most likely a problem with your eltronic throttle body or possibly airflow meter.

Testimonial: "ive already changed the throttle body and also the abs pump yesterday and its still the same! do you think its the airflow meter then?"
