Dynamic Rear Proportioning (DRP)

The Dynamic Rear Proportioning (DRP) is a control system that replaces the hydraulic proportioning function of the combination valves in the base brake system. The DRP control system is part of the operation software in the EBCM. The DRP uses active control with existing ABS in order to regulate the vehicle's rear brake pressure.

DTC C1248 sets in order to indicate that the EBCM illuminated the red BRAKE warning indicator. The EBCM cannot perform DRP due to another fault in the ABS/TCS system. DTC C1248 will never set by itself.
