Restoring airbags after an accident

Restoring airbags in a car

Airbags in a car provide protection to the driver and passengers during an accident by creating a layer of air during deployment that softens the impact.

If the airbag goes off

On modern cars, even in the basic configuration, two airbags are usually installed - the front passenger and the driver. When an accident occurs, at the command of the impact sensor, the airbags are activated, while the trim on the steering wheel and instrument panel is torn, and the interior space is filled with specially impregnated fabric. The airbag inflates like a parachute, softening the force of impact during a traffic accident, thereby saving passengers in the cabin.

After the airbags have deployed, something needs to be done with them, since it is impossible to drive with the airbags deployed. There are several ways to troubleshoot:

• try to restore the PB;
• replace parts, install new airbags;
• look for used spare parts at car wreckers;
• make dummies by dismantling SRS parts.

It is not always the case that the safety system after an accident on a car is completely restored - such work requires a lot of financial costs, quite a lot of time, and highly qualified workers.

Airbag restoration

To restore the airbag functionality, you must:

• replace the squib;
• install new shock sensors;
• reflash or change the SRS control unit;
• restore damaged casing.

It is unlikely that the car owner will be able to carry out the entire range of restoration work on his own - there is a high risk that the system will not work in the event of an accident. Aebag repairs are carried out by specialized car services, and the work is quite expensive. For example, in Moscow, replacing a driver's squib will cost an average of 4 to 5 thousand rubles, the cost of repairing a dashboard after an accident is around 10-12 thousand rubles, the cost of work depends on the specific car model. Reflashing (repairing) the SRS unit is also not cheap - from 3 to 5 thousand rubles. When the safety switch in the seat is triggered, you have to completely disassemble the chair and reupholster the upholstery.

Restoring the dashboard after the airbag deployed

Repairing the instrument panel after an accident is one of the most labor-intensive tasks in the SRS passive safety system. To replace the airbag and “sew up” the dashboard, you need to completely remove the dashboard. The most difficult thing to do is restore the appearance of the trim on the passenger side - if the plastic is sealed or sheathed with material carelessly, it will be noticeable.

Restoring the panel after the airbags are deployed is carried out in the following sequence:

• the negative terminal is disconnected from the battery;
• the glove compartment is removed;
• the instrument panel is dismantled;
• the fastenings of the instrument panel frame are unscrewed;
• the panel is dismantled and completely disassembled.

In this case, it is necessary to disconnect all the wires from the dashboard that interfere with removal, remove buttons, deflectors, etc. from the panel. Complete restoration of the dashboard with the installation of new airbags sometimes costs more than tens of thousands of rubles, so car owners are often offered to only restore the casing, without repairs and installation of airbags. But even such work is not cheap; many car owners try, if possible, to find a used instrument panel at car dismantling yards. As a rule, installing second-hand parts is cheaper than a complete repair, and besides, the original panel looks more natural - if the dashboard is restored, it is still noticeable upon careful examination. The restoration of the instrument panel after an accident is carried out by tuning studios; the work is divided into several stages:

• dismantling the dashboard;
• preliminary cleaning and treatment of the dashboard;
• sealing damaged areas using special adhesives;
• making patterns from material chosen by the customer;
• installation of covers on the restored instrument panel;
• Installation of dashboard, electrical connection.

At the request of the car owner, the instrument panel is decorated with decorative chrome elements or natural wood inserts, and an additional acoustic system is installed. The tuned panel looks very impressive, while all the defects that were previously present on the dashboard are hidden.

Why do you need to reflash the SRS control unit?

The airbag control unit contains a special program; when the impact sensor is triggered, it changes. If you completely restore the passive safety system, but do not touch the SRS control unit, an indicator on the instrument panel will light up, indicating a PB error, and in the event of an accident, the airbags will not work. The ECU is reflashed in many specialized car repair shops, but it should be noted that not all units can be restored. When flashing, the data is reset and returned to its original state.

On many cars, the SRS unit is located under the instrument panel, next to the gearshift lever. It is usually covered with a plastic panel; removing the ECU is very simple, you can do it yourself. On the Infiniti FX, the airbag control unit is removed as follows:

• the gearshift lever tunnel is removed;
• two connectors going to the block are disconnected;
• The bolts securing the ECU housing are unscrewed.

Assembly is carried out in reverse order.

DIY AIRBAG SRS restoration

If a car owner is going to sell a car that has been in an accident, it is at least unfair for him to install dummies instead of the PB. By selling such a car, he puts the buyer at risk, since without a passive safety system in an accident, the passengers of the car can be seriously injured.

If the car is not new, you can try to restore the SRS by purchasing all the necessary parts from used cars, but here it is necessary that the “donor” car is not damaged. You will need to buy:

• the airbags themselves;
• seat belts with squibs, they are activated in an accident in 99 cases out of 100;
• shock sensors.

All parts can be changed independently, but specialists must configure or reflash the SRS control unit. Still, you shouldn’t trust the work to dubious companies - even though the repairs will cost a little more, the car owner will be sure that his car is in perfect order.

How to repair a driver's airbag

Let's look at the principle of restoring a driver's airbag:

• disconnect the airbag from the steering wheel;
• dismantle the plastic decorative cover;
• disconnect the squib; on many cars it is secured with four nuts;
• In any case, the cushion and squib must be replaced with new parts, but the cover is restored in many workshops.

As a rule, new airbags are very expensive, which is why restoring airbags is popular.
