Pump Motor

The BPMV contains a motor driven recirculation pump. The pump serves two purposes:
1. During ABS reduce pressure events, it transfers fluid from brake calipers back to master cylinder; and
2. During traction control, it transfers fluid from master cylinder to front brake calipers. The pump and motor are located within the BPMV and are not serviced separately.
