HINT:
After the repair, clear the DTCs. If "Inverter Coolant Water Temperature" does not show an abnormal value (110°C (230°F) or -50°C (-58°F)) when the power switch is turned on (IG), the condition is judged as normal.
(If a Low malfunction exists in the HV coolant temperature sensor wiring, 110°C (230°F) is displayed and if a High malfunction exists, -50°C (-58°F) is displayed.)
