Code P0C47 Saturn Description

The hybrid/EV battery pack coolant pump circulates coolant through the drive motor battery coolant radiator, drive motor battery coolant cooler and the hybrid/EV battery pack to control the temperature of the hybrid/EV battery pack. An enable signal from the hybrid/EV powertrain control module 2 to the hybrid/EV battery pack coolant pump provides overall control of the pump. When this circuit is high, the pump can operate. The pump is controlled with a pulse-width modulated signal from the hybrid/EV powertrain control module 2 to the hybrid/EV battery pack coolant pump. The higher the duty cycle the higher the pump speed. The hybrid/EV battery pack coolant pump provides a hard-wired pulse-width modulated feedback signal to the hybrid/EV powertrain control module 2. During normal operation, this feedback signal provides pump speed information to the hybrid/EV powertrain control module 2. The hybrid/EV battery pack coolant pump has some self-diagnostic capability. If the hybrid/EV battery pack coolant pump determines there is an internal fault it provides this information on this same feedback circuit instead of pump speed information.
