DTC Summary

The hybrid vehicle control ECU detects malfunctions which prevent the rear inverter shutdown circuit from shutting down. Detection is performed during the shutdown sequence when the power switch is turned off. If rear inverter operation is detected after a shutdown signal was sent to the rear inverter by the motor generator control ECU (MG ECU), the hybrid vehicle control ECU will determine that there is a malfunction and store this DTC.

The cause of this malfunction may be the following:

Inverter with converter assembly shutdown circuit (rear motor) internal circuit malfunction 

• Inverter with converter assembly malfunction
• Wire harness (SDNR) malfunction
• Connector malfunction

Hybrid motor control inverter assembly rear shutdown circuit (rear motor) internal circuit malfunction 

• Hybrid motor control inverter assembly rear malfunction
• Wire harness (SDNR) malfunction
