Control Unit/Hydraulic Unit

The Bosch DSC III 5.7 control unit/hydraulic unit is located inside the engine compartment on the right hand side.

Both the control unit and the hydraulic unit are replaceable as separate components.

All processing functions for ABS, ASC and DSC are performed in the combined control/hydraulic unit. The control unit is also responsible for processing the wheel speed signals and providing them to other control units.
