C12E0 BUICK Description
The ABS Pump Motor is a bi-directional motor and is an internal part of the Brake Pressure Modulator. There are three solid state relays in the electronic Brake Pressure Modulator that operate the pump. The ABS Pump Motor runs every few brake stops in order to fill the high pressure accumulator with brake fluid. The Anti-Lock Brake System (ABS) Module monitors the ABS Pump Motor. The ABS Module sets the OBDII code when the ABS Pump Motor is not to factory specifications.
