Im sorry but you are factually WRONG  As an Automotive Engineer with a keen interest in vehicle dynamics I can assure you that traction control and EDL are operate in two very different methods  All traction control systems monitor differential axle wheel speeds comparing the driven axle to the nondriven axle  any differences outside the scope of the allowed tollerances will ONLY result in either a BOTH driven wheels on the same axle being braked or b the engine ECU reducing engine output or c a combination of a and b  EDL does NOT compare differences between front and rear axles it ONLY compares differences between the left and right wheels on the same axle and brakes just ONE wheel there is NO engine power intervention  Whilst they are both addon functions of modern ESP systems and use the same related hardware and electronics the software control of the two different systems are distinctly separate and help moderatecontrol different aspects of vehicle dynamics  Dont forget Wikipedia articles are not considered valid references for other Wikipedia articles so if you have read something contrary on another Wiki article it doesnt automatically mean it is correct
