Dynamic Driving Control (If Equipped): Notes

The MS45 ECM contains two different throttle progression functions (Sport and Normal). The Dynamic Driving Control function is selected by pressing the "Sport" button located in the center console (1).

The switch provides a ground signal (input) to the ECM when pressed. The MS45 activates the sport characteristics for the Electronic throttle control (EDK). This provides an increase in throttle opening and response time over the non-sport position.

When this function is activated, the function indicator light in the Sport button is illuminated by the Electric Power Steering (EPS) Control Module. When the ignition is cycled, this function resets back to the non-sport function (it must be re-selected by the driver).

The ECM additionally provides the request for the Dynamic Driving Control function over the PT CAN bus to the following control modules:

If equipped:

• Electronic Power Steering (EPS)
• Instrument cluster (Kombi)
• Automatic transmission (EGS)
• SMG 6-speed sequential manual gearbox
