What to do if the car safety indicator is on

When the airbag lamp is faulty, the light is on:

1. Instrument self-test.

In the short time of entering the car and ignition, the instrument will automatically detect, and the airbag light will automatically go out after the automatic detection is completed, which will be about 5 seconds, which is a normal phenomenon. If the airbag light is still on for a long time after the self-test, then it can be judged that there is really a fault.

2. False failure.

If the battery loses power, it will also cause the airbag light to turn on. And the airbag will also feedback the signal of low air pressure of a certain airbag to generate a fault code, at this time, just clear this fault code.

3. True failure.

If the above two reasons are ruled out, then it is possible that the line is faulty and should be repaired in time. The cause of this failure may be the failure of the airbag, collision sensor, airbag hairspring, etc.

What should I do if the safety indicator light is on? What is the first thing to use a special instrument to detect the fault code? Which airbag is malfunctioning, or the plug is malfunctioning, usually the airbag is malfunctioning, or the airbag light is lit due to the loose plug under the seat.

The indicator light on the automobile instrument is used to display the working status of each system, and one of these indicators is an alarm light. Under normal circumstances, the alarm lights will light up together at the moment the car is powered on, and then it will go out, if there is an alarm light that is not extinguished, it means that there is a problem in the car and the driver needs to pay attention.

Notes:When a passenger sits on the car seat, the seat position is occupied by the sensor monitoring, the signal is sent to the control device, the control device turns on the safety trigger switch, detects whether the seat belt is plugged in, this sensor is actually a pressure sensor switch, when the passenger sits on the seat, a voltage signal will be generated, transmitted to the car control unit.

The sensor also serves the purpose of detecting whether the passenger is occupied, so as to confirm whether the passenger airbag is deployed to protect the passenger in the event of a car collision.

1. The light flashes when starting the vehicle self-inspection. If someone is not wearing a seatbelt (mainly the front seat) while driving, the light will turn on or flash.

The safety indicator has been flashing, it is a normal phenomenon, it is not a problem, and it does not need to be lifted, this power consumption is very small, do not worry that he will consume too much power of the vehicle battery.

1.If the car safety indicator is still on or flashing after the engine is turned on, it means that the vehicle's NATS vehicle anti-theft system is faulty, and it needs to be repaired at the 4S shop as soon as possible to eliminate the hidden danger of driving.

2.In addition, if you need to perform special operations on the vehicle's anti-theft system, you can find a repair shop and ask them to help you unplug the wiring harness of the safety indicator so that the vehicle's safety indicator will not turn on again.

3.The function of the safety indicator is to indicate whether the car has entered the engine anti-theft state. When you operate the smart key and lock the car, the safety indicator will automatically light up and flash.

At this time, we know that the engine immobilizer system of the car has begun to work normally, and there is no need to operate anything else.

4.What needs to be popularized is that it is normal for the car safety indicator to flash all the time.

2.Excessive dirt and carbon deposits, abnormal air circulation, and inability to accurately control the normal air intake volume, resulting in unstable gas levels and making the engine not work well.

3.The low fuel pressure combined with the poor constant pressure performance leads to a low level of atomization in the system, making it difficult for the car to start.

Extended Materials. About the car dashboard.

1.The car dashboard is a device that reflects the working conditions of each system of the vehicle. Different cars have different gauges. However, the conventional instruments of general automobiles include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc.

2.A variety of indicators or warning lights are made under the instrument panel of modern automobiles, such as coolant level warning light, fuel level indicator, washer liquid level indicator, charging indicator, high and low beam dimming indicator, transmission gear indicator, brake anti-lock braking system (ABS) indicator, drive force control indicator, airbag (SRS) warning light, etc.

Generally:

1) When the seat belt is not fastened, the seat belt indicator light will be always on, and the seat belt needs to be fastened at this time; (2) The seat belt has been fastened, but the seat belt indicator light on the car dashboard is still on, which may be that the socket of the monitored seat belt sensor is loose and needs to be plugged in tightly.

It is normal for the seat belt indicator light to be always on, and the seat belt light is always on after starting the car, and the warning light goes off after plugging in the seat belt, and if it is still lit, the connection line on the seat belt plug lock is still lit.

The car's safety indicator is also shown to be on after the engine is turned off. It means that your vehicle is still in a powered state, but it is not starting the vehicle. You pull the key off, and then it won't show up again.

After the West Lake, the car's safety indicator is still on, if it is after the West Lake, the safety indicator is still on, then it is because your car key has not been removed in time, or he has just turned off, and the safety indicator light cannot be extinguished in time, just after a while.

If it is the red light in the upper left corner, it is the oil lamp, which means that the oil is insufficient. If the orange light in the bottom corner is the fault light of the engine, which means that the engine is faulty. If the top of the right side is the seat belt warning light, it means that the occupants of the car are not wearing seat belts, and the bottom of the right side is the battery failure, so check the battery.

Different safety indicators have different ways to deal with them, such as if the oil is insufficient, it is recommended to use the oil dipstick to check the oil, if the height of the oil is lower than the oil dipstick, then the oil is too little, as long as the cavity is added to the oil, if the driving time is not very long, the oil is always less quickly, then you have to see if the fake oil is added, if so, it is recommended to change the oil of ***.

There are more and more electronic systems on the car, many car owners do not know what a light on the car means, and there are many car owners do not know what a button on the car is to control, it is recommended that these car owners carefully read the car manual or vehicle manual. If the dashboard fault light is on when you are in the car, you need to go to the 4S shop in time or check the fault and repair it. After some fault lights on the car are on, you need to stop driving immediately, otherwise there may be a serious traffic accident, and you must pay attention to sensitivity.
