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.
Temperature differences during sea transport can easily trigger the tire pressure warning. After inflating the tires to the standard pressure (usually 2.5 Bar), most vehicles will automatically clear the warning after driving a few kilometers; some models require manually clicking "Tire Pressure Reset" in the "Vehicle Settings" on the central screen.
Testing is mandatory. Troubleshooting electrical devices in the car is part of the standard procedure. We will test the window lift motors, mirror folding, air conditioning compressor and fan, electric seat tracks, etc. Any stuttering or failure of electronic components will be recorded.
