Introduction to DSC

Control Module/ Hydraulic Unit

The control module used on the DSC III sys-

tems varies between models. The DSC III

5.3 system uses the same control module

configuration at the ASC+T5 system.

The control module is an 83 pin unit located

in the E-box.

The DSC III 5.7 system integrates the control

module into the hydraulic unit. This reduces

the size and wiring required for DSC opera-

tion. Additionally the motor relay and valve

relay have been replaced by solid state final

stages in the control module.

On E39 and E39 applications, the control module/hydraulic unit is located ahead of the

passenger side strut tower. The hydraulic unit contains the following components:

• Two pre-charge solenoid valves

• Two changeover solenoid valves

• Four intake solenoid valves

• Four outlet solenoid valves

• One return pump
