DTC C1248
Circuit Description
The dynamic rear proportioning (DRP) is a control system that replaces the hydraulic proportioning function of the mechanical proportioning valve in the base brake system. The DRP control system is part of the operating software in the EBCM. The DRP uses active control with the existing ABS in order to regulate the vehicle's rear brake pressure.
Conditions for Running the DTC
One or more faults have been detected by the EBCM in the ABS/TCS systems.
Conditions for Setting the DTC
One of the following conditions exits:
DTC C1236 sets and ignition voltage is less than 8.5 volts.
DTC C1254 or C1255 sets.
DTCs C1265 and C1267 set.
Two wheel speed sensor DTCs on the same axle set.
Action Taken When the DTC Sets
The EBCM disables the DRP for the duration of the ignition cycle.
The red Brake warning indicator turns ON.
