Tongshen Car Diagnostic Instrument

In an old auto repair shop on the outskirts of the city, Lin Mancang, a 47-year-old electronic control master, discovered that the "central control screen" and "car computer" of some cars can talk to people - not speaking voice, but speaking fault codes and system prompts. Every car like this comes with a "rule". If you make a wrong repair, something in the car will come out. The car will "remember" it. A car is more than just a machine. It records the owner's route, habits, emotions, and secrets, all stored in the data of the ECU and central control screen. The vast majority of cars are scrapped normally. But some cars - those that have killed people, those whose owners were wronged, or those whose obsession was too deep - the data has not been cleared, and they have "lived" and become "cars with rules." The way to deal with them is not to do physical repairs, but to finish what it left unfinished. Lin Mancang, 47 years old, has been working as an auto repairman for 26 years. I have done electronic control calibration in my early years and understand the bottom layer of ECU, CAN bus and flash writing. Later, I "saw a car that shouldn't exist" and quit my job to open a full warehouse auto repair shop. There is a modified diagnostic instrument left by the master, which can read hidden fault codes that ordinary instruments cannot read. Please remember! • A "seemingly normal" system prompt pops up on the central control screen, but it is actually a rule for the repairman (for example, "Please change the driver" = the driver of this car is "broken") •The ECU stores fault codes that do not exist in the manufacturer's database, and each code corresponds to an "event" •Rules must be followed, and the repairman keeps the price of violation secret.
