Pump supplies fluid to Active Centre Diff (ACD) in the Transfer Case and Active Yaw Control (AYC) in the rear diff.
The ACD distributes torque between FRONT wheels and REAR wheels..."aces" for faster acceleration...and to reduce understeer (front wheels "flying out" too much on a corner.)
The AYC transfers torque from SIDE-to-SIDE for the REAR wheels only...to help control excessive oversteer (rear wheels "flying out" too much on a corner.)
