The reductant pump control module receives a duty cycle signal from the PCM and controls the reductant pump operation in relation to this duty cycle. The reductant pump control module controls the reductant pump by energizing the pump motor three phase drive circuits at the required speed in the required direction, as commanded by the PCM. The reductant pump control module sends diagnostic information to the PCM.
