The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
Modern WSP systems are microprocessor controlled and employ two stage valves that permit fine control over the air pressure in the brake cylinders. This is essential to be able to capture and control a sliding wheel and to minimise the amount of air resource used by the WSP. When the brake is applied, the WSP first applies the dynamic brake.
The computer control system needs the front drive shaft to turn, so that it can monitor and compare the rotational speed of both the front and rear drive shafts. If the rear drive shaft starts to turn faster than the front, the system interprets that (along with input from other sensors) as traction loss.
ESC control light. Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology [1] [2] that improves a vehicle's stability by detecting and reducing loss of traction (). [3]
Mitsubishi's S-AWC logo. S-AWC (Super All Wheel Control) is the brand name of an advanced full-time four-wheel drive system developed by Mitsubishi Motors.The technology, specifically developed for the new 2007 Lancer Evolution, [1] the 2010 Outlander (if equipped), the 2014 Outlander (if equipped), the Outlander PHEV and the Eclipse Cross have an advanced version of Mitsubishi's AWC system.
Furthermore, automatically locking differentials can cause a loss of control on ice where an open differential would allow one wheel to spin and the other to hold, while not transferring power. An example of this would be a vehicle parked sideways on a slippery grade. When both wheels spin, the vehicle will break traction and slide down the grade.

ESC control light; Electronic stability control (ESC) can reduce the speed of the car and activate individual brakes to prevent understeer and oversteer. [37] Understeer occurs when the car's front wheels do not have enough traction to make the car turn and oversteer occurs when the car turns more than intended, causing the car to spin out. [37]
