The possible causes are: 1. Poor circuit contact; 2. Broken or damaged bulb filament; 3. Loose connections in the circuit, affecting the resistance value of the lighting circuit and causing the dashboard computer to misjudge. The method to eliminate the bulb with an exclamation mark on the car dashboard is: Turn off the engine, use a wrench to remove the negative terminal connection of the battery, wait for 15 seconds, and then reconnect it. The warning light should disappear.
