Circuit/System Description
WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
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.
