traction control on ANY vehicle will only brake spinning wheels in an effort to regain some grip. if theres no grip available, the system will just brake on the spinning wheels constantly. to emulate locking diffs, the system would have to brake the wheels to a complete standstill, and as far as im aware, because they usually operate through the ABS system, this is not possible, assuming the freelander system works the same way as any other TC system does
That is exactly how TC works The Freelander system is an old design so brakes the wheels with a slow pulse rate compared to modern systems that buzz the brakes. Weather this is benefit or not I don't know but my wife's VW Tiguan is'nt as good as my Freelander on slippery surfaces even though I consider the Tiguan's tyres better!!
