DESCRIPTION
The skid control ECU (master cylinder solenoid) measures the speed of each wheel by receiving signals from the speed sensors. These signals are used for recognizing whether all 4 wheels are operating properly. Therefore, all wheel signals must be equal.

AUTO LSD system
The AUTO LSD system aids traction by using the traction control system to control
engine performance and braking when one of the rear wheels begins to spin.
The system should be used only when one of the rear wheels spinning occurs in
a ditch or rough surface.
