This is an internal fault detection of the drive motor generator power inverter module. This fault is handled inside the hybrid powertrain control module and no external circuits are involved. The hybrid powertrain control module contains two motor control modules and the hybrid powertrain control module. These modules share dedicated internal drive motor generator power inverter module circuits. The modules listed below are part of the drive motor generator power inverter module and are not serviced separately.
- Hybrid powertrain control module
- Motor control module 1
- Motor control module 2
