P1588 2004 Honda Civic Hybrid DescriptionMotor Power Inverter (MPI) Module control the DC/AC conversion (From the Integrated Motor Assisted (IMA) battery's 144 V DC to the IMA motor's 3-phase AC and vice versa).
The MPI module is air cooled. The heat fed through the heat sink is exhausted to the trunk compartment by the Intelligent Power Unit (IPU) module fan. The MPI module has a built-in temperature sensor. The sensor transmits temperature data to the Motor Control Module (MCM) for protection
