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.
EBCM Controls
The EBCM controls the current to the boost valve so that pressure can be applied to the wheel brakes. The boost valve is a spool type valve which is referenced to the controlled pressure so that for a given current applied, a specific pressure is expected. The boost valve controls the pressure apply from the accumulator through the rear isolation valves directly to the rear wheel brakes, and through the front isolation valves, to the individual front pressure chambers behind the secondary pistons in the MC, which in turn apply pressure to the front wheel brakes.
