P1D93 HONDA Description
The 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). The motor control module (traction) detects a malfunction and stores a DTC when the coolant temperature is abnormally high continuously for the prescribed time or more while a run command is issued to the electric motor control module coolant pump and the radiator fan.
