What does a triangle with an exclamation mark mean in a car?

[DelAllison]

The exclamation mark inside a triangle displayed on the car dashboard is a general fault warning light. The reasons for its illumination are as follows: 1. The color is usually red, and it lights up for 2 seconds during power-on self-check before turning off. 2. It lights up when there is a fault in the fuel injection system. 3. For general faults, the warning light remains lit. 4. For severe faults, the warning light flashes. 5. The warning light automatically turns off once the fault is resolved. Common faults that trigger the general fault warning light include: 1. Overheating of the dry dual-clutch transmission or clutch. 2. Intervention or malfunction of the fuel cutoff system. 3. Fault in the parking sensor. 4. Fault in the engine oil pressure sensor. 5. Warning or fault in the traction control system.
