Replying to Topic 'Is it all the same?'
Are you sure you are not talking about DSC?
DSC = Dynamic Stability Control = Different sensors track in what direction you are steering and whether or not the car is actually turning in the right direction. If both sensors do not indicate the same rate of turn, a skid is detected and brakes are applied individually to each wheel to help get out of the skid.
TCS = Traction control system = In acceleration, if a sudden increase in the rotation speed of your wheels is detected, the throttle of your engine is reduced to prevent wheel slip.
The European Mazda 6 has DSC and TCS standard (I think). Us North American folks only get TCS (as an option). .... shudder ...
Frankly, this jumble of acronyms is a mess. Car manufacturers often use different acronyms for the same systems and often go as far as using the same acronym for different systems.
