|What is P0C15 code meaning?

The Power Inverter Module, often referred to as the Drive Motor Generator Power Inverter Module, contains two motor control modules and the hybrid powertrain control module. Each motor control modules operates its respective drive motor generator based upon hybrid powertrain control module commands. Each motor control modules controls the speed, direction and output torque of its respective drive motor generator through the sequencing actuation of high current switching transistors called insulated gate bipolar transistors. Each drive motor generator operates utilizing 3 phase AC. Each insulated gate bipolar transistor operates a single phase of the drive motor generator. Each phase is individually identified as U, V and W. Each motor control modules monitors the temperature of each phase in order to detect power inverter module overtemperature conditions.
