P0A7A9E | Generator Inverter Stuck On |
Generator inverter fail signal detected (circuit malfunction) (1 trip detection logic) |
| Comes on |
Master Warning: Comes on |
SAE Code: P0A7A |
|
P1C5F19 | Generator Inverter Circuit Current Above Threshold |
Generator inverter fail signal detected: A malfunction is detected in any of the generator components (generator inverter, generator (MG1), generator resolver, motor generator control ECU, etc.). (1 trip detection logic) |
| Comes on |
Master Warning: Comes on |
SAE Code: P1C5F |
MONITOR DESCRIPTION
If too much current is detected flowing through the generator inverter, the generator inverter transmits an inverter fail signal to the motor generator control ECU. Upon receiving this signal, the ECU will illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN
HINT:
- After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
Click here
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 2 minutes or more.
- Turn the ignition switch to ON and wait for 5 seconds or more. [*1]
- Turn the ignition switch to ON (READY) and wait for 5 seconds or more. [*2]
- Press the HV EV CHG HOLD mode switch to enter HV drive mode. [*3]
- Depress the accelerator pedal of the vehicle with the engine stopped and the shift lever in P to start the engine. [*4]
HINT:
Check that there are no abnormalities (abnormal sounds, coolant leaks, etc.).
- Drive the vehicle approximately 10 minutes mainly using the engine. [*5]
NOTICE:
As the state of charge of the HV battery may be low after driving in fail-safe mode, it will automatically be charged for 5 to 10 minutes with ignition switch ON (READY) after repairs have been performed.
HINT:
[*1] to [*5]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
- Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform the normal judgment procedure again.

NOTICE:
- After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.
Click here
- When disconnecting and reconnecting the auxiliary battery.
HINT:
When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.
Click here
- After troubleshooting and repairing all output DTCs, be sure to replace the inverter with converter assembly. (The inverter with converter assembly may have been broken or damaged due to overheating.)
HINT:
- P0A7A9E or P1C5F19 may be output as a result of the malfunctions indicated by the DTCs in table below.
- The chart above is listed in inspection order of priority.
- Check DTCs that are output at the same time by following the listed order. (The main cause of the malfunction can be determined without performing unnecessary inspections.)
- If DTC P0A7A9E is output, replace the inverter with converter assembly after completing repairs.
