What Do Fault Lights on the Car Dashboard Mean?

When the "colorful" vehicle information warning indicator lights up on the dashboard, do you know the reason? This is because the system is performing self-inspection on the vehicle parts, and it is all on and off instantly. If there is an alarm light that does not go off, it is a problem with the system it represents. Through the fault light, you can clearly determine where the car is malfunctioning.

 

Problems Indicated by Fault Lights

 

1. Engine oil fault lamp

The oil fault light indicates that the oil pressure is abnormal, the driver must stop and check immediately to see if the oil level is low, whether the engine noise will be loud, etc. If you feel that the engine is operating normally, it is best to drive to the nearest 4S shop or repair shop as soon as possible. If the engine is abnormal, it is best to call the tow truck to avoid greater losses. The engine oil is to ensure the lubrication of the engine. If the lubrication is poor, the engine may be seriously worn or even scrapped.

 

2. Water temperature alarm light

The water temperature warning light is on, indicating that the engine interior has overheated and the cooling system has failed. High water temperature may cause the engine cylinder head to deform or even pull the cylinder, which is very serious. At this time, it is necessary to stop immediately and wait for the water temperature to drop, check whether the water level of the antifreeze pot is normal, and replenish it if there is a lack of liquid.

 

3. Battery alarm light

The battery fault light is on to indicate that there is a problem with the generator charging system or the battery. If the engine does not generate electricity, the car may break down when the battery is exhausted. If there is a problem with the battery, it may not be possible to stop the car after the car is turned off. In short, if you encounter such a situation, you should find a 4S shop or repair shop as soon as possible.

4. Tire pressure warning light

For vehicles with tire pressure monitoring, this light is on to indicate that the tire pressure of the vehicle is insufficient or the pressure is too high. It should be stopped in time for inspection and treatment, otherwise there is a risk of flat tire. If the tire pressure is high, you can deflate some gas. If the tire pressure is low, you should replace the spare tire. Some cars have real-time tire pressure values that can be judged more intuitively. We even recommend the programmable TPMS series to increase safety. 

 

5. Fault lamp of ABS system

The ABS light is on to indicate that the ABS (ESP) system is faulty, but it does not affect the normal use of the vehicle brakes, but there is no anti-lock braking (slip resistance, body stability control) function. You must avoid high-speed driving and avoid sudden braking. The ABS system is generally paired with a programmable TPMS to achieve a high-quality driving experience.

 

6. Engine fault light

The engine failure light is always on to indicate that there is a problem with the engine of the car, especially the electronic control system. Under normal circumstances, the car can continue to drive in this situation, but it will enter the emergency (protection) mode. If possible, find a repair shop as soon as possible.

 

7. Airbag warning light

If the airbag light of the car is always on, it indicates that the airbag is faulty. In this state, the car can still operate normally, but if a collision occurs, the airbag will not open. That is equivalent to no airbag system, drivers must be vigilant.

Tire pressure monitor system and tire pressure sensor can better improve the performance of the car. Welcome to contact us for the best price of programmable TPMS.
