Dynamic Rear Proportioning

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The dynamic rear proportioning is a control system that replaces the hydraulic proportioning function of the mechanical proportioning valve in the base brake system. The dynamic rear proportioning control system is part of the operation software in the electronic brake control module. The dynamic rear proportioning uses active control with existing ABS in order to regulate the vehicles rear brake pressure.

The red brake warning indicator is illuminated when the dynamic rear proportioning function is disabled.
