Active Braking Mode

WARNING: This page is about a different car, the 2012 Land Rover Range Rover Sport and 2011 Land Rover Range Rover Sport. However, it is still accessible from the selected car via links, so may be relevant.

The active braking mode is used to generate and control hydraulic pressure to the brakes for functions other than anti-lock brake system (ABS) braking, e.g. DSC, emergency brake assist (EBA), ETC, HDC, dynamic application of the parking brake and adaptive speed control.

For active braking, the anti-lock brake system (ABS) module energizes the pilot valves and priming valves, starts the return pump and energizes all of the inlet valves. Brake fluid, drawn from the reservoir through the master cylinder and priming valve, is pressurized by the return pump and supplied to the inlet valves. The anti-lock brake system (ABS) module then operates the inlet valves and outlet valves, as required, to modulate the pressure in the individual brakes. Some noise may be generated during active braking.
