DTC P0A78-308 - Drive Motor "A" Inverter Performance

DESCRIPTION

The HV control ECU receives a collision signal from the center airbag sensor and the No. 1 circuit breaker sensor to determine that the vehicle has been damaged. Then, it cuts off the high-voltage system to ensure safety. If the HV control ECU receives the collision signal only from the center airbag sensor, it turns OFF the system main relay and the power switch. If the HV control ECU receives the collision signal only from the No. 1circuit breaker sensor, it turns only the system main relay OFF.
