What does it mean when a vehicle displays a code?

When a vehicle displays a code, it indicates that the driver is being alerted about a lack of antifreeze in the engine cooling system, and antifreeze needs to be added. The functions of antifreeze: 1. It provides anti-corrosion protection for components of the cooling system; 2. It prevents scale buildup, avoiding a reduction in the radiator's cooling efficiency; 3. It ensures the engine operates within the normal temperature range. The hazards of not replacing expired antifreeze: 1. It can cause the water in the antifreeze to evaporate, altering the antifreeze's freezing point and affecting its performance; 2. It fails to provide anti-corrosion, anti-rust, and rust-removal functions for the engine, impacting the engine's lifespan; 3. It increases viscosity, reducing cooling efficiency.
Recently, several alphanumeric codes suddenly flashed on my car's dashboard, which really startled me! After searching online, I learned that those were vehicle trouble codes, essentially the car's computer sending out warnings. For example, a code like P0300 indicates an abnormality in the engine ignition system, possibly due to worn spark plugs or clogged fuel injectors. Ignoring it could turn a minor issue into a major one, leading to costly engine damage. I immediately drove to a nearby repair shop, where they used an OBD-II scanner to pinpoint the root cause. The technician said I was lucky to address it promptly, avoiding bigger troubles. Now, I'm extra sensitive to these codes and always check the dashboard during car washes to prioritize safety.
