What does a triangle with an exclamation mark on the car dashboard mean?

[DakotaLee]

The triangle with an exclamation mark on the car dashboard is a general fault warning light, which can illuminate for various reasons: 1. Typically red in color, it lights up for 2 seconds during power-on self-check and then turns off; 2. It illuminates when there is a fault in the fuel injection system; 3. For general faults, the warning light stays on continuously; 4. For severe faults, the warning light flashes; 5. The warning light automatically turns off once the fault is resolved. Common faults that trigger this warning light include: 1. Overheating of the dry dual-clutch transmission or clutch; 2. Fuel cut-off system intervention or malfunction; 3. Parking sensor fault; 4. Engine oil pressure sensor fault; 5. Traction control system warning or fault.
