1.
Set the starter key to the "LOCK" position.
2.
Disconnect the three-phase cable (U, V, and W terminals) from the
HV motor.
3.
Using the electrical tester, measure the resistance between the
HV motor terminals.
HINT
If the motor temperature is too high, the resistance will largely
vary. Therefore, measure the resistance at least 8 hours after the
vehicle has stopped.

Is the measured value within the range of standard value?
Go to step 3.
Replace the HV motor.

Inspecting the HV motor
Is any abnormal noise heard?
Inspect the HV motor and repair or replace if
necessary.
After repair or replacement, go to step 4.
