Inspection Procedure

Check for open, short and +B short in wire harness between HV ECU MIT and MIVG terminals and converter & inverter M-INVT, M-GINV terminals (See page IN-41).


Confirm that there is no open circuit in the wire harness. If the voltage between the HV ECU MIT or MIVG terminal and body ground is always more than 5V with the ignition ON, the motor inverter temperature sensor circuit has +B short.

Check for open in motor inverter temperature sensor and then replace converter & inverter assembly. Check motor inverter temperature sensor (See page HV-14).
