P1d7c Acura DescriptionThe motor power inverter (MPI) module (traction/generator) and the voltage control unit (VCU) are cooled by the motor control module (traction) which operates the electric motor control module coolant pump monitoring the coolant temperature and the temperature of various components and sends a request for operation of the radiator fan to the powertrain control module (PCM).
