The car fault light came into being with the development of automotive electronic technology. Nowadays, the car will be equipped with a micro-computer. Through the internal program management of the micro-computer, the electrical components of the car begin to work in an orderly manner, once somewhere in the system. When an abnormality occurs, the computer will alarm. The form of the alarm is to light the fault light, which is also a characteristic of the humanization and intelligence of the automobile.
There are various kinds of car fault lights. Each fault lamp represents a different meaning. Different vehicle configurations are different, and the fault light will be associated with the basic equipment of the car.
The indicator light of the car dashboard is on or flashing. This is to remind the driver that there is some kind of fault in your car. Every time you start the car, you must pay attention to check your own dashboard.
There are too many indicators on the dashboard, and many owners may not understand what each indicator means:
1, red = hazard indicator
2, yellow = fault indicator
3, green light = normal work indicator
Car dashboard fault light diagram1. Water temperature meter warning light:
Water temperature gauges are generally pointer-type on the vehicle. The pointer is generally indicated in the red area at normal temperature, and its temperature is generally around 95 degrees Celsius, and some cars are higher. The indication of the water temperature gauge can tell us the current temperature of the vehicle, indicating whether the engine is now in the normal temperature working range, and whether there is abnormality such as high temperature.
If the pointer indicates to the red alarm area of ​​the water temperature meter, you should drive the car to the side of the road in time, stop the car to check whether the engine has a pot, if it is indeed open (if the water tank is opened, it is strictly forbidden to open the water tank cover with bare hands to avoid being burnt) Start the car and let it cool down slowly; then wait for rescue or replenish cooling water, then drive to a nearby service station for inspection and repair, find out the cause of the high water temperature and promptly remove the fault.
2. Engine fault light:
If the alarm light is on or the pressure gauge is too high, we must turn off the engine. First check if the oil is missing. After the vehicle is turned off, pull out the engine oil dipstick and see if the oil page is at the minimum and maximum. between. If the oil is at a high altitude, look for a service person to check to see why the light is on.
3, brake warning light:
If the brake warning light is on when the normal hand brake is released, you need to get off the train and check the brake oil level in time to see if the brake oil is missing. If the brake oil is seriously lacking, you should pay attention to find out whether there is leakage. Since the brake oil will not be lacking too much in an instant, the brake oil leakage will cause the brake to malfunction. Be careful. After the inspection, if there is no shortage, you need to drive to the service station to check whether the brake oil level sensor or the hand brake light switch is faulty. phenomenon.
4. ABS warning light:
If the ABS lamp is lit during driving, it indicates that the ABS electronic control system is abnormal; in this case, the normal normal braking system will not cause problems, but the ABS does not work. As the owner of the vehicle, it is not necessary to be afraid of this situation (not to say If there is a fault in the ABS, there will be no brakes, because they are two relationships that are not in series. The ABS will only start when the wheels are about to be locked, and will not start when the wheels are not locked, but the brakes are still available as long as the brake system is not faulty. As long as you can drive normally, you can go to the repair station for maintenance as soon as possible.
5, airbag warning lights:
If the airbag self-test fails after the vehicle is started, the safety warning light will light up; at this time, the airbag may not bounce in the event of an accident, and the passive protection is not possible; however, the vehicle can continue at this time. Drive, don't worry too much, just go to the repair station as soon as possible to repair it.
