A fault light with an exclamation mark in the middle lights up on the instrument panel of the vehicle. This fault light may be the warning light of the brake system, the tire pressure monitoring warning light, the general fault display light, and the transmission fault light. The specific fault light needs to be seen outside the exclamation mark. The shape and the identification of different fault lights are different.

If the outside of the exclamation mark is a triangle, it is the tcs indicator light, if the outside of the exclamation mark is in the shape of a yellow gear, it is a transmission fault light, and if the outside of the exclamation mark is in the shape of a car window, it is a car windowWiperMalfunction light, if the outside of the exclamation mark is in the shape of a light bulb, it is a light bulb failure light.

The yellow exclamation mark fault light in brackets is the tire pressure monitoring indicator light. When the tire pressure monitoring indicator light is on, it means that the tire pressure is abnormal, and the air pressure is too low or too high. The car owner needs to turn on the double flashing lights, slow down and pull over, and place the tripod in the trunk 150 meters behind the vehicle, so as to remind the vehicles behind to pay attention to safety.

Reasons for the tire pressure monitoring light to come on are:

1. The vehicle has been driving for too long, and the air pressure has not been pumped up in time, causing the air pressure of the vehicle tires to be too low, thus turning on the tire pressure monitoring indicator light;

2. The air pressure of the tire is too high. If the air pressure is too high, it may be that the weather is too hot, the gas is heated and expands to cause the tire pressure to be too high, or the suspension connecting parts are severely worn, the positioning of the tire will be inaccurate, and there will be serious problems. The eccentric wear situation, resulting in excessive tire pressure;

3. The tire is punctured. If the tire is punctured, it will slowly leak air. When the air pressure is low, the tire pressure monitoring indicator will light up, and the tire needs to be repaired.
