[Solved] Opel Zafira A 1.8 Petrol - Persistent Airbag Light, Error 82: Passenger Side Sensor Circuit Issue

Hi
Zafira A 1.8 petrol

The pillow light is on all the time. Deleting doesn't help.
After checking Opcom: 82 - passenger side airbag sensor circuit malfunction

I checked the plug under the passenger seat - it's ok
I put the resistor in the plug.
I had a resistor with regulation, I set the resistance from 1.7 to 2.9 so about every 2 tenths.
But still the same, after clearing the error returned after 2-4 seconds.
I checked the cable near the ankle with the meter to the sensor itself and it is ok. So it's not worn anywhere.

I stripped the passenger door and checked the wires from the impact sensor to the sensor under the gears - it's ok
I replaced the driver sensor (I had to use cables because the plugs are different) but unfortunately the same error continues

I only have access to the Opcom interface (from Allegro) I read somewhere that these crap can show something wrong.
I read in another forum that these regular interfaces might show something wrong.

I'm thinking of buying a used sensor and sensor. How can you check the bump sensor?

Is it worth replacing the cable, e.g. the sensor from the door, although it is ok.
If so, which cable should I use?
I don't know what else can I do?

Use a tester / interface that does not lie.

I don't have access and opportunities because I live at the end of the world

Check it under the driver's seat because in one Opel he showed the pillows the other way round.

Done.
I replaced the airbag controller under the gear stick and the problem disappeared.
