DTC P321E-318: All HV Gate Blocking Range/Performance [12/2014 - ]: Description
The hybrid vehicle control ECU sends a block signal to the motor generator control ECU (MG ECU) to shutdown the power supply to the motor. When the system is not in the on (READY) state, it sends an HSDN (MG shutdown signal) signal from the hybrid vehicle control ECU to the motor generator control ECU (MG ECU) to check the function of the HV gate block. When a malfunction is detected in the HV gate block function, DTCs are stored.
| DTC No. | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P321E | 318 | An open or ground short in the HV gate block signal circuit when the gate is operating. When the HV gate block function check is performed (when the ignition switch is turned from on (READY) to off), the inverter voltage (VH) drops and current flows in the inverter. (Both generator (MG1) and motor (MG2) are malfunctioning.) (1 trip detection logic) |
