We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.
A proper inspection relies on equipment, not just eyes. The inspector should use a paint thickness gauge to measure 50-60 points across body panels; original paint is typically 80-150 microns. An OBD diagnostic scanner reads stored and pending fault codes across all control units, and for EVs it also reads battery state of health and charge cycle counts. The car must go on a lift for the underbody check: frame rails, suspension components, oil leaks and accident repair marks are only visible from below. A battery tester checks starting voltage and charging system health, and a tread depth gauge documents tire condition. Ask for the report to include raw readings and dated photos rather than a simple pass/fail summary - that is what makes it verifiable.
The catalytic converter contains precious metals, making it a target for theft. During chassis inspection, we check if the welding points of the catalytic converter are in their original state. Once verified, the vehicle will be sealed after being handed over to port logistics to prevent disassembly and resale.
