Throttle Progression Switch
The MS S52 control system contains two different throttle progression program curves (Sport and Normal). The sport program is selected by pressing the sport switch located in the center console switch panel.
The switch provides a ground signal as an input when pressed. The MS S52 activates the sport characteristics for the EDR throttle control. This provides an increase in throttle opening over the non-sport position.
At the same time the ZKE control module is signaled over the CAN and K-Bus to activate the sport servotronic (increased road feel) steering characteristic program.
