If the vehicle is involved in an accident, the airbags may be deployed. It all depends on the severity of the incident. However, if you later drive without airbags, the on-board computer will beep every time you start the engine, and in addition, an icon will flash, notifying that there are no airbags. It is necessary to correct the current situation, and here we are already talking not about repairing the airbag, but about replacing it.
Instructions
Step 1
However, you cannot simply take and replace the pillow; you also need to intervene in the on-board computer. The SRS unit is responsible for its operation, which you will need to reprogram.
Step 2
Let's take a closer look at the airbag deployment system. In the event of an accident, a shock sensor is triggered, firing out belt squibs, as well as the airbags themselves. The SRS unit is then alerted that the system has been triggered. Subsequently, each time the ignition is switched on, the malfunction warning light on the vehicle status plate will light up. And even if you change the airbags, it will still flare up. As a result, the pillow will not pop out when needed, or it will not work at all.
Step 3
The average cost of an airbag at the helm ranges between $ 200 and $ 400. The key factors here are the year of manufacture of the car and, in fact, the model. Simply replacing the pillow, as previously stated, will not achieve anything.
Step 4
To solve this problem, a lot of work will need to be done. To begin with, of course, you need to replace your spent airbags with new ones.
Step 5
Then you need to reprogram the SRS unit. To do this, replace the error code with the new car's code, after which the on-board computer will "think" that there was no accident, and the airbags were not ejected. Although it seems so simple at first glance, in practice everything turns out to be different.
Step 6
The whole catch is that the machine manufacturer complicates the encryption every time. This leads to the fact that it becomes more difficult to deceive the on-board computer. This, in turn, forces the car enthusiast to fork out for a new SRS unit, which costs about $ 600-1500.
Step 7
If you have neither the opportunity nor the desire to buy a block, copy the data from the dump file until the moment of the traffic accident to the flash card. However, in order to do this, you need to have some knowledge in this area. Otherwise, it is better to seek the help of specialists. If you try to take a copy of the dump file without proper dexterity and skills, you can provoke the release of pillows.
Step 8
Having a USB flash drive with data in hand, flash a dump of a working system using the programmer. This programmer must first be bought in a specialized store. And do not forget to purchase the necessary microcircuits. Next, it remains to replace the necessary microcircuits in the block with already flashed ones or to reflash the old ones.
