DTC P0A3C (39): Motor Drive Module (MDM) Overheating: General Description

If the motor power inverter (MPI) module temperature increases when driving, the flag over temperature (FOT) signals from the MPI module change from a high voltage level to a low voltage level to trigger self-protection. If the FOT signals stay at a low voltage level for a set time (t1), the motor control module (MCM) detects a malfunction and stores a DTC.
