Actually i better recommend THIS cos it can be plugged directly into the connector as there might be a shorting pin in it and the resistor's wire terminals seem a bit weak for that

Hi mate.
I received this late yesterday and once I found the plug removed it and put the gismo in its place the follwoing happened.
SRS light stayed on.

So I removed it and measured its resisitance with my multimeter. it read 2.4 ohms.

I tried it again, SRS light stayed on. read the code "short circuit fault".

Removed it, read the fault codes again "open circuit fault".

So now stuck. You know me, my limite4d abilities seem to say that this gismo's resistance is not enough? But I thought 2.2 ohms was supposed to be enough.

Do you have anything else I can try?
Regards
Stan.

Hi, did you check in the plug if it has that shorting bar or not? what code did you get before using the resistor when the SRS light first came on? also with the resistor connected into the plug can you erase the code?

I assumed that you had recommended this gismo as it would overcome any shorting bar, so, no didn't check, I'll have to work out a way of getting around it before trying it again. Where it is, it is very difficult to see into the socket part of the connector.

Surely if it says "short circuit" then the two prongs on the gismo have got past the shorting bar and into the sockets to conduct current through the resistor?
Or, could they both be contacting a metal shorting bar which itself is then conducting current to short circuit the resistor?

As for the original fault, I cannot remember frankly, I think it was "open circuit" but obvs I'll plug it back into the connection to the bag and check.
Thanks for this.
I'll get back to you.

That was the ideea based on how it looks but i didnt try myself at the airbag plug as when i had the SRS light it was a pretensioner and this kind of resistor worked for that one but the airbag side might be more sensitive.... unfortunately there is no clear info about te D2's airbag original resistance cos if it keeps giving the short circuit code pluged in and open circuit unplugged then IMO a higher resistance is needed maybe the 3 or 3.3 ohm one.

Right.
Well I had a good look at the socket and there didn't appear to be any sort of shorting bar. It is just a very plain-two hole socket, round holes, nothing else.
I looked at the pin part of the connection to see if that told me anything, not much, there seemed to be two pins and on the outside of each of the two pins there seemed to be a sort of bit of metal designed to hold the pin tight to the socket, I would maybe have to take pics for you to understand what I mean.

I guess to determine what resistance is needed higher and higher resistors would have to be tried.

Finally, I plugged the connector back in to read the code as you asked what it was originally.

And I could not read it as, guess what? There was no code as all was OK. No SRS warning light and no codes found "circuit tested clear".

The fault had been intermittent all along. So now of course I have to think that an apparently sound connection in a dry place, (as strangely under the steering column is dry, despite the fact that it is obvious that others before me have been in there as connectors were not bundled up as they should have been!) was not in fact a good connection.

I totally do not trust this, I really do expect it to go wrong again. I just hope that it will hold together until it gets through its MOT when I will eventually be able to address this matter further.

Thank you very much for pointing me in the right direction,

I'll have to research the resistance of the airbag and if I find it I will put it up here for those who wish to know it.
