Last time on the highway, I suddenly noticed the dashboard displayed a 'scan' prompt, which scared me into pulling over to check the manual. Later, the mechanic explained that this is actually the onboard computer performing a full vehicle check, much like a smartphone's self-test during startup. If no issues are found after the scan, the prompt will disappear automatically; but if it stays on, you should pay attention. Especially for some car models where the 'scan' light flashes while driving, it might indicate poor battery contact or a sensor covered in mud. Once, my colleague's car had the 'scan' light on the entire way after rain, and the dealership found water seepage in the engine wiring harness connector. It's recommended not to use a high-pressure water gun to spray directly into the gaps of the hood during car washes, as these precision components are really sensitive to water.
