What does 'check' mean when displayed on the car dashboard?
2 Answers
When 'check' is displayed on the car dashboard, it indicates a problem with the engine's electronic control system, and you should promptly go to a 4S shop for inspection and repair. The reasons for the 'check' light appearing on the dashboard are: 1. Poor engine performance; 2. Faulty sensors or other mechanical components of the engine; 3. Issues or deviations in the engine's exhaust emissions. The dashboard indicators and their functions are as follows: 1. Door status indicator: shows whether the doors are fully closed; 2. Battery indicator: displays the working status of the battery; 3. Brake pad indicator: shows the wear condition of the brake pads; 4. Oil pressure indicator: displays the engine oil pressure; 5. Coolant temperature indicator: shows the temperature of the engine coolant.
When I saw the 'check' light on the dashboard, I immediately realized it might be the 'check engine' light alerting me to a problem with the car. After driving for so many years, experience tells me not to underestimate it. The most common causes are issues with the engine system's sensors, such as the oxygen sensor or air-fuel ratio problems, which may lead to non-compliant emissions; a clogged fuel system or a faulty ignition coil can also trigger it. Battery or alternator failures sometimes cause this too, as the system detects abnormalities and lights up the warning. The key is not to ignore it—stop and check other dashboard indicators, like oil pressure or temperature. If the problem persists, take it to a professional repair shop to read the fault codes with diagnostic tools. It usually costs a few hundred yuan to fix, otherwise, engine damage could result in much higher repair costs.
