Airbags fault all at once

[Zans]

Hi,
Fired up the car first time after the rebuild and my horn wasn't working so after connecting the vagcom i got big errors on the airbags


I have no idea how to fix any of that and the horn either. Horn itself is working when connected to a battery, the relay under the dash is working as well (ticking + 2ohm resistance) and the 20 amp fuse is working.

Any help would be greatly appreciated

tried clearing them to see if they come back?

Are there any fuses or relays i could check? The problem seems to be with the control unit because the error is for multiple airbags

In the measuring blocks i read:
Airbag driver side: too high
Airbag passenger side: too high
Belt tensioner front drive side: too high
Belt tensioner front pass. Side : too high
Belt tensioner rear driver side : correct
Belt tensioner rear passenger side: correct
Belt tensioner rear center : too high
Battery disconnect igniter: too high
Voltage supply : correct
Occupied seat sensor passenger side : too high
Belt inquiry front driver side : too high
Belt inquiry front passenger side : too high

Something tells me you need to take a look at the airbag module..... loads of codes relating to pretty much all of the faults pointing to that. Check the wiring, checking with a multimeter what your getting to see if it is infact “Too high”

Thanks for the reply!

Where would i find the j234 module and how much should i measure?

Sorry mate just seen this. I don’t actually know, you’d need to do some research. My logical thinking is pointing at that module. Or at least where power is delivered to it via a relay or something.

normally resistance too high is a wiring related fault...

I occasionally get this fault in both the S3 and A2 if the passenger seat is moved and I believe its related to the condition of the wiring plug under the seat for the airbags...

No idea where the airbag module is tbh but you can check the wiring on the seat belts etc

i did remove the driver seat to repair it and noticed there was a plug going from the floor that didn't connect anywhere in the seat... could that be the issue?

 

[S3AMJ]

I would say yes.... the underside of the seat is a yellow plug

And where should i plug it ? there is no such connector in the seat...

 

[Zans]

so i removed my steering wheel and found this


the cable was split and that explains the horn not working and maybe the airbags issue.... open connector means infinite (too high) resistance on the airbags?

anyone got a part number for this thing?

 

[Zans]

after i got a new cable fitted the horn started working again (hooray!!) but the airbag faults still remained except the driver side airbag....
i also removed the seat and found no connector that goes to the yellow plug coming from the floor

where could i find the airbags control module?

 

[S3AMJ]

After a bit of research apparently it’s under the centre console bud

HI did you ever find out where the Air Bag Module was looking for mine and I am at a loss.

Thanks

Nope.. I just left it as if because I'm out of the country most of the time and don't have the time to tackle it.. I'll keep this thread updated if I ever get to the bottom of it
