I did some research by measuring the ocupancy sensor which was okay, and figured out which components You need to bypass the sensor if it is broken.

So You need soldering iron, not shaking hands and one 3k3 to 30k resistor and diode 1N4007.

schematic diagram is in the picture


this is modded bypass modul that was previously posted on some forums, but that "OLD" one caused the airbag light off but the seat was in control unit of airbags NOT OCCUPIED. therefere I did this mod which will make the seat "OCCUPIED" even if nobody is there!!!!!

Hey buddy,

I want to turn the airbags off as i want to put my child in the front (he is a nightmare to keep entertained) Im thinking, if we can trick the occupancy sensor to say the is always a passenger, we can also trick it to say there isnt one.

Does anybody know the resistance of the sensor if no one sits in the seat?

Then i make a resistor up for that and off we drive.

Kind regards
