Steering Wheel Movement Speed
The Steering wheel angle sensor module (SAS) (4/68) informs the Power Steering Control Module (PSCM) (6/164) about the actual steering wheel angle speed via the controller area network (CAN). This allows the Power Steering Control Module (PSCM) to calculate the optimum desired value for the pump motor speed for optimum steering assistance, irrespective of the speed of steering wheel movements.
