Yes. We will use a professional diagnostic tool to scan all vehicle systems, including the Engine Control Unit (ECU), Transmission Control Module (TCM), Anti-lock Braking System (ABS), and Airbag Module (SRS), and provide English screenshots of all current and historical Diagnostic Trouble Codes (DTCs).

All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

Due to legal restrictions preventing unregistered vehicles from high-speed driving on public roads in China, most of our dynamic tests are conducted in a closed area (with a maximum speed of around 60 km/h). This is sufficient to test for suspension noise and low gear smoothness, but it cannot simulate high-speed wind noise and tire balance vibrations at 120 km/h.
