Toyota Corolla Cross: DC/DC Converter Voltage Sensor "A"(VL) Circuit Voltage Below Threshold (P0E3116,P0E3117,P0E311F)
DESCRIPTION
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.

- 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 (READY) and wait for 5 seconds or more. [*1]
HINT:
[*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.
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.
CAUTION / NOTICE / HINT
HINT:
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.
