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.
Circuit/System Description
The BPMV internal hydraulic brake pressure sensor (BPS) provides brake pressure input to the EBCM. This BPS data is utilized during VSES events. The EBCM also monitors the brake pressure sensor BPS and the body control module (BCM) serial data message of the brake pedal position sensor (BPPS). These readings are compared between the BPS and BPPS and are used to insure the actual braking intent of the driver, during conditions when the brake is applied and when the brake released/decel-accel.
