Operation

This system carries out all the normal anti-lock and brake distribution functions of the ABS 5.7 with EBD and also ensures the following:

Acceleration Slip Regulation (A.S.R.)

Engine braking torque regulation (M.S.R.)

differential lock via action on the brakes (T.C.)

The functions are ensured by adjusting drive torque and applying a braking force to one or both drive wheels.

If one or both drive wheels tend to slip during acceleration, the control unit orders the engine control unit to reduce the torque transmitted by the engine to the wheels and almost simultaneously brakes the wheel or wheels without the driver having

to do anything.

If the wheels tend to lock during hard deceleration, the ABS control unit requests the engine control unit to adjust engine braking toruqe to prevent car stability.

The system can be cut out by activating a button located on the console.

A led comes on on the button and a message is displayed on the instrument panel DOT matrix to indicate deactivation of the ASR/MSR.

The button warning light comes on and the DOT matrix message is repeated to indicate system cut-out due to a fault recorded by the control unit.

ASR/MSR intervention is indicated by the warning light on the dashboard flashing.

Each time the vehicle is started up the ASR/MSR function is activated, even if the ignition has been turned off with the function deactivated.
