My OBD2 reader and my instrument cluster reports a short circuit somewhere on the wire, for the Passenger airbag squib 2.
The passenger airbag has two squibs, the R12/4 and R12/5, from which a 2 and 2 wire cable comes and connects into the X28/12 plug (4 wires).
The part number of this wiring is A1725406005
When unplugging this wiring from the X28/12 connector, the short circuit error dissappears (but an open circuit error appears, logically).
This leads me to believe that the short circuit occurs between this plug (X28/12) and the airbag.
Now, on the WIS wiring diagram, I see there is a switch on the R12/4 and R12/5.
If I remove the wiring entirely, the multimeter reports no short circuits on it.
But if I plug the wiring to R12/4 and R12/5, both 2 wires for both plugs/squibs report a short circuit on the multimeter.
No error is shown for any short circuits on squib 1, though.
Do you have any idea if this switch is supposed to be open or closed?
Also, do you know how that switch is being actuated?
Some things about the pictures:
1 - I realize there is some spring in this switch (X28/12), which makes a short circuit on the wires for R12/4 and R12/5, when this plug is disconnected. I made sure the spring makes no contact, when checking with the multimeters for other short circuits.
2 - That orange thing must be pushed in, when the squib plug is connected. Perhaps that actuates the switch from the diagram?
3 - What is that? Is it only reinforcement for the wires, so they don't break?
Sorry for being so technical, but I think this can only be explained in technical words.
