What does the triangle exclamation mark on the car dashboard indicate?

[VonJuliet]

The appearance of a triangle exclamation mark on the car dashboard indicates issues such as poor contact with external lights or malfunctions in the position lights, taillights, turn signals, rear fog lights, license plate lights, etc. This indicator is a general fault warning light. When it illuminates, it is advisable to carefully inspect all the bulbs in the vehicle, especially the brake lights and license plate lights. If the car's headlights have been modified, this icon may sometimes appear as well. If all the bulbs are intact and functioning normally, check the wiring harness in the trunk for any damage. If there is any damage, wrapping it with tape can solve the problem. For vehicles with a multifunction steering wheel, pressing the function buttons on the steering wheel to access the warning menu can provide specific alerts. If an accurate diagnosis cannot be made, it is recommended to visit a 4S store or a professional auto repair shop, where a technician can use a computer to read the fault codes, identify the issue, and perform timely repairs.
