Only perform protective ground conductor and insulation resistance measurement after the vehicle has been de-energized.
Otherwise test results will be incorrect.

Never perform the protective ground conductor and insulation resistance test at a high-voltage component between "HV+" (plus) and "HV-" (minus).
Otherwise, the high voltage component will be damaged.

Carefully attach probes of insulation resistance tester to high-voltage connections.
Otherwise the high-voltage connections may be damaged.
