Circuit Description - DTC P3140 - Information Code 350: Notes

WARNING: This page is about a different car, the 2002 Toyota Prius. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

When using an OBD II scan tool other than TOYOTA hand-held tester, check all the steps.
When using TOYOTA hand-held tester, confirm the information code and check it.

If the HV ECU detects the operation of the safety devices (removal of the service plug, inverter terminal cover and sensor cover) while the vehicle is not running (with the vehicle is stopped), it will shut down the system main relay. It the safety devices are correctly installed, it will resume the normal operation after the power source is supplied again. If it does not, there is a possibility of an open circuit, so perform the same Inspection as the information code 351.
