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.

It usually refers to very small stone chips on the hood from high-speed driving, nail scratches on the inside of door handles, slight curb scratches on the edges of wheels, and minor wear on interior plastic parts. These do not affect the vehicle's functionality or corrosion resistance.

The method to deceive the dashboard warning light is to install a resistor. Our technicians will deeply read the real-time resistance values from the airbag control module (SRS Module) data stream and check for any non-factory stitching or adhesive marks on the steering wheel/passenger panel to uncover the disguise.
