DTC SUMMARY MALFUNCTION DESCRIPTION The hybrid vehicle control ECU detects malfunctions which prevent the motor (MG2) inverter shutdown circuit shutting down the hybrid vehicle control system. Detection is performed during the shutdown sequence when the power switch is turned off. If motor (MG2) inverter operation is detected after a shutdown signal was sent to the motor (MG2) inverter, 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 SDWN (MG2) internal circuit malfunction
DESCRIPTION The motor generator control ECU (MG ECU) sends shutdown signals to the inverter to cut the power supply to the generator (MG1) and motor (MG2). If the power switch is turned off, the motor generator control ECU (MG ECU) will send a GSDN (MG1 Shutdown Signal) signal and MSDN (MG2 shutdown signal) signal to check the function of the HV gate block. If a shutdown malfunction is detected, this DTC will be stored.
