| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P321F-319 | Part of HV Gate Blocking Range/Performance | 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 power switch is turned from on (READY) to off), the inverter voltage (VH) drops and current flows in the inverter. (Any of the generator (MG1), motor (MG2) or rear motor (MGR) is malfunctioning.) (1 trip detection logic) | Inverter with converter assembly | Does not come on | Master Warning Light: Comes on |
