No no no no no. What you are talking about is ABS (antilock braking system). That is what prevents wheel locking during hard braking on slippery surface. What I meant was ABLS (active brake limited slip) which operates by braking the faster spinning wheel during hard acceleration. Pretty much the same as traction control and electronic limited slip differential and all the other names its given by different car manufacturers. It's described in detail in page 5-27. Which is exactly the cause of confusion since the manual says traction control is turned off with the vdc button in one section but in another section it says abls stays on even if vdc is off.
Yes, I do know that traction control/abls/electronic lsd/etc..... is nothing more than a software program added to the already existing ABS software and hardware. And that's why a sure way to totally kill off traction control in any car is pulling out the abs fuse.
