If the sound signal stopped at the same time and an airbag error has appeared, it is more likely a problem in the plume.
The first thing to do is to remove the battery from the battery and let the car stand for about 20 minutes without power. It is not difficult to remove the steering wheel with two bolts under Thorx (asterisk). The steering wheel is tight, so it is necessary to pull the wheel hard, but gently, so as not to recline it. It's better to use a special tenant if there is one.
Now we need to remove the plastic covers of the steering column and get the contact coil.
Inside the contact coil, the long three-wire plume is laid out, so it is likely to be damaged.
If the plume is broken far from the end, I'll have to change the whole reel. If it came close to the end, you could shorten the plume itself a little bit. I'm gonna have to turn the plug. Do it carefully and not to confuse the veal. Otherwise, pressing the sound can cause an airbag to fire.
After the rebrake, you need to contact the random jumpers after the missing person and, if all is well, to rewind the tape coil and gather everything in reverse order. The problem must be gone.
