Brake Fluid Level Switch
Fluid level switch is mounted in the brake master cylinder reservoir. If the fluid level is correct, the switch provides a ground signal to the DCS control module.
If the fluid level drops below the specified level, the switch opens and the ASC/DSC functions are switched off.

Master Cylinder/Fluid Reservoir
The master cylinder contains the central valves in both the front and rear brake circuits, Similar to the Bosch DSC system. The central valves allow fluid to transfer during DSC controlled interventions.
The brake fluid reservoir has internal baffles that minimize fluid foaming during controlled interventions. The charge pump pick up is mounted low on the reservoir to prevent air from entering the system during regulation. The fluid level switch will signal the control module to cancel DSC regulation if the fluid is below the safety margin level.
