What does it mean that the airbag indicator light of the vehicle will light up?

The electronic control of airbag system is a passive safety protection system (see automobile safety performance).

When used in conjunction with seat belts, it can provide effective collision protection for passengers. When a car collides, the car airbag can reduce the head injury rate, face and face by 25%.

The injury rate decreased by about 8 0%.

The reason why the airbag light is on

1. Circuit problem of the reason why the airbag light is on.

Speaking of circuits, we all know that there are various problems in circuits, so let's see if there is any possibility of abnormal connection. A detector is usually used to check for faults.

Whether the line is clear, and if the signal line voltage is normal, measure whether the ground wire is open. See if you can access its control unit and test it one by one, such as hair.

I can't get in now, so I have to unplug the computer of the relevant parts. Is it caused by the interference of the signal data cable?

See if the airbag control computer can work normally, enter the airbag, the computer finds that the fault is permanent, and replace the steering wheel to eliminate the fault.

Except ... If you still find that you can't get in, this phenomenon still exists. At this time, you can check whether its power supply line can be electrified.

This is the reason why the detector can't detect it because of poor grounding. Check the two plugs of the distributor on the relay box, that is, the airbag signal line.

Turn into the street. Unplug one of the plugs and test its control unit. If it is normal.

2. The plug problem of the reason why the airbag light is on.

In fact, many times, it's just that the plug is loose. This may be due to people accidentally touching it, but people often don't notice this situation. while

If the plug is loose, find the plug under the back seat and press it tightly.

3. Sensor and data failure of airbag lighting cause.

In case of sensor failure and data reading error, professional maintenance should be carried out in strict accordance with manual measurement and precautions of various models and styles.

Protection, at this time must be carried out under the operation of professionals.

At the same time, airbags are also related to some small actions of our car owners. Some car owners like to modify the interior decoration, which will affect the normal connection of sensors.

Connect, and then affect the airbag normal pop-up.
