6.1.11. DSC HU/CM block of system of dynamic stability

The compact and easy integrated DSC HU/CM block of the increased reliability is used.

The DSC HU/CM block counts entrance signals of all sensors and operates the electromagnetic valve and the engine of the pump (inclusion/switching off), regulates pressure of working liquid in cylinders of brake mechanisms and activates functions of system of dynamic stability (ABS, system of electronic distribution of brake efforts (EBD), the TCS, DSC systems and the amplifier of emergency brake application).

The design and operation of the hydraulic block of the DSC system are similar to a design and operation of the hydraulic block of modern model 323 (BJ), except for operation of the amplifier of emergency brake application.

The DSC HU/CM block removes a signal of management of torque of the engine and a signal of speed of the car through CAN channel.

The DSC HU/CM block also removes a car speed signal on wires
