Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.
We will never perform blind deep disassembly unless there are clear severe fault codes or extreme noises. The sealing of the engine and transmission is crucial, and compromising the factory seals to investigate non-existent issues is unprofessional. We rely on data flow and external acoustic and fluid analysis to make judgments.
Yes. For hybrid vehicles, technicians will conduct forced switching tests between EV (electric) and HEV (hybrid) modes, focusing on the sensation of clutch engagement and reading the hybrid system's specific fault codes to ensure the complex dual power system operates correctly.
