The motor generator control ECU, which is built into the inverter with converter assembly, detects pre-boosting high voltage (VL) using the voltage sensor in the boost converter to control boosting. The motor generator control ECU also monitors the boost converter voltage sensor signal line and detects malfunctions.

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.
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
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 (READY) and wait for 5 seconds or more. [*1]
[*1]: 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.
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.
P0E3116, P0E3117 or P0E311F may be stored due to a malfunction which also causes the DTCs in the table below to be stored. In this case, first troubleshoot the output DTCs in the table below. Then, perform a test to attempt to reproduce the problems, and check that no DTCs are output.
| System | Relevant DTC | |
|---|---|---|
| Hybrid control system | P0AD915 | Hybrid/EV Battery Positive Contactor Circuit Short to Auxiliary Battery or Open |
| P0ADD15 | Hybrid/EV Battery Negative Contactor Circuit Short to Auxiliary Battery or Open | |
| P1C8449 | High Voltage Power Resource Circuit Short during Ready ON | |
Check for DTCs.
| Result | Proceed to |
|---|---|
| None of the following DTCs are output. | A |
| DTCs of hybrid control system in the tables below are output. | B |
| DTCs of motor generator control system in the tables below are output. | C |
Turn the ignition switch off.
