Dynamic Rear Proportioning (DRP) DTC's

Vehicles with four wheel disc brakes are equipped with Dynamic Rear Proportioning (DRP). The DRP system is integral to the anti-lock brake control module. The DRP maintains brake balance and maximizes brake efficiency for all loading configurations. DRP detects the onset of front versus rear slip imbalance and limits the rear pressure. If the rear slip significantly exceeds the front slip, the DRP system will reduce the rear pressure. If this condition occurs, the driver will feel a slight pulsation in the brake pedal. The DRP system will be disabled if one Diagnostic Trouble Code (DTC) is set from condition 1 and condition 2 or condition 3, or if one DTC from condition 2 and condition 3, or if two or more DTCs are set from condition 1.

Condition one:
- C1095
- C1196
- C1200
- C1212
- C1216

Condition two:
- C1155
- C1158
- C1233

Condition three:
- C1145
- C1148
- C1234
