Abstract
A method of performing a pump check for a brake system comprises determining a first position of a pump with a pump position sensor upon ignition of a vehicle. A pump motor is powered based upon a preselected operating condition. A second position of the pump is determined with the pump position sensor. The first position of the pump and the second position of the pump are compared. The pump motor is confirmed as operational when the second position of the pump is different from the first position of the pump.
