What faults will occur if the vehicle body computer is damaged?

If the vehicle computer is damaged, the vehicle may experience abnormal display brightness, inability to lock or unlock, failure to start, unstable idle speed, increased fuel consumption, and other issues. Below is a related introduction: The role of the vehicle computer: The vehicle computer is like the human brain, as it can control the working conditions of various vehicle components. For a simple example, if the vehicle's oxygen sensor detects a high oxygen content in the exhaust, it can be determined that the engine is not burning completely at that time. Subsequently, the oxygen sensor will transmit this information to the vehicle computer, which will then control the fuel injection system's fuel volume to improve the vehicle's combustion efficiency, thereby reducing fuel consumption and emission pollution. Precautions: Generally speaking, unless subjected to short circuits, water immersion, or fire, the durability of the vehicle computer is very high, and it can usually last a lifetime.
It's really troublesome when the car's onboard computer malfunctions. I once experienced this with my old car—the window suddenly got stuck and wouldn't roll up no matter what. The next day it rained, and the interior got completely soaked. The door locks also stopped responding; the remote key fob didn't work, so I had to manually unlock it with the mechanical key, making entry and exit a hassle. The headlights and taillights flickered on and off, making nighttime driving dangerous. Sometimes, the dashboard warning lights would flash randomly, like the airbag light turning on for no reason, which gave me a scare. The audio and anti-theft systems also acted up, setting off false alarms that disturbed the neighborhood even when parked. Worse yet, the seat heaters stopped working, leaving me freezing in winter, and the wipers quit during rainstorms, making it nearly impossible to see the road. These issues are often caused by short circuits in the computer module or software bugs, leading to a complete electronic system failure. If not fixed promptly, they can trigger chain reactions in other components, like rapid battery drain or a stuck electronic parking brake. My advice is to get these symptoms checked by a professional repair shop as soon as possible to avoid more serious problems down the line.
