1.
Set the starter key to the "LOCK" position.
2.
Remove the inverter terminal block cover and the ECU box termi-
nal block cover.
3.
Using the electrical tester, measure the resistance between the
terminals of inverter and high-voltage J/B (in the ECU box).

Check the P(+) and N(-) terminals of DC high-voltage cable
(inverter side) for failing connection (looseness, wear, or melting
damage).

Is the measured value within the range of standard value?
Go to step 4.
Replace the DC high-voltage cable between
the terminals of inverter and high-voltage JB
(in the ECU box).

Inspecting the DC high-voltage cable
Is any defect found?
Retighten the terminals.
Replace the terminals if abnormal wear or
melting damage is detected.
Go to step 5.
