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.

No, it does not. International shipping (especially RoRo) usually takes 30 to 60 days, during which the vehicle is stationary. A dead 12V battery, natural tire pressure loss, and even wiper aging due to temperature differences are all reasonable physical wear during long-distance transport. We strongly recommend that overseas buyers bring a portable jump starter and an air pump when picking up their vehicles at the port.

The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.
