vehicle's airbag light flashes or stays on after it is activated, it basically means that the airbag is malfunctioning, so we must pay attention to it. Because the airbag involves the safety of the people in the car, if it is not dealt with in time, the hidden dangers are great. Qashqai This car does not have many feedback airbag problems. After investigation, it is basically caused by airbag sensors, line connectors or airbag hairsprings. To determine the specific cause, the most direct way is to use a computer to read the fault code, which can basically be judged accurately. Let's talk about it in detail below.
First of all, some alarm causes are caused by system problems, so when reading the fault code, if it is an intermittent fault alarm, there is no substantial alarm problem, which can be dealt with by pin code. .
The first reason is that the airbag line connector is loose. Especially, this problem is more likely to occur if the seat has been dismantled or the related line has been disconnected by yourself. When reading the fault code, the basic fault code B1147 is reported, that is, the wire harness is disconnected and short-circuited, which means that the line connector is loose or the wire harness is disconnected. Of course, the possibility of a loose connector is the greatest.
Solution: This can only be processed in a 4S shop or repair factory, and check the overall connection of the line. In 4S shops, a certain amount of working hours will be charged, around 80.
The second reason is the airbag sensor. When reading the fault code, the basic fault code is B1118, and at the same time it will mark which side it is. This can be determined as the sensor problem, as long as it seems to be replaced.
Solution: Take Changchun as an example,Buy airbag sensor accessories at a 4S shop, the price is about 500, free of labor and time.
The third reason is the failure of the airbag hairspring. If there is a problem with the hairspring, the airbag warning sign will be lit, and the reading of the fault code is basically B1049. The driver's airbag module is open. At the same time, the multi-function steering wheel or the horn may not work well. If it exists at the same time, it can basically be determined that there is a problem with the balance spring.
Solution: Just replace a hairspring. The price of replacing the hairspring assembly in a 4S shop is 240 yuan, and the labor cost is about 320 yuan.
In summary, that is, some of the reasons that may cause the airbag failure alarm, you can refer to the treatment.
