Engine Drag Torque Control (MSR)

If the vehicle is operated in low gear while coasting downhill or if is the vehicle is suddenly shifted into a lower gear, the drive wheel may be slowed down by the engine braking effect to rapidly which can result in an unstable operating condition, resulting in the drive wheels locking up.

Engine Drag Torque Control (MSR) provides protection against locking of the drive wheels.

Advantage: The drive wheels retain their lateral stability in overrun mode.

The wheel speed sensors tell MSR as soon as the wheels are about to lock. MSR then briefly reduces the engine's drag torque by opening the throttle slightly.
