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.
Brake Pressure Modulator Valve
Brake Pressure Modulator Valve (BPMV) contains hydraulic valves and pump motor that are controlled electrically by EBCM. BPMV uses a 4 circuit configuration with a front/rear split. BPMV directs fluid from reservoir of master cylinder to left front and right front wheels and fluid from the other reservoir to right rear and left rear wheels. Circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.
