Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Dynamic Rear Proportioning (DRP)
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
If any DTCs are retrieved, GO to Inspection and Verification - NGS.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
