Engine Drag Torque Control (MSR)

OPERATION
In the same way as Automatic Stability Control (ASC), Engine Drag Control (MSR) is integrated in the Anti-Lock Brake (ABS) control unit. The engine is influenced via Digital Engine Electronic (DME) and Electronic Throttle Control (EML).

A signal is sent to the DME control unit when increased slip occurs at the drive wheels when the vehicle is coasting. Consequently, the deceleration fuel cut-out function is deactivated. In addition, the EML control unit is instructed to adapt the throttle position until the wheel slip is once again within the permissible range.
