Airbag Light On
907 - 25/8/17 at 10:53 AM

Not the 7 but the 5 this time.

I have fitted cloth seats from an earlier model that don't have the heating elements, weight sensors & airbags in them.

I would like to fool the airbag lights in the dash, otherwise I will have to put the leather ones back for MOT.



Any ideas ?

Something like this any good?

I had this when I fitted some Mk1 RS Sparcos to my ST170. The standard ST170 half leathers had side airbags, the Sparcos did not.

I tried all of the tricks on ebay and elsewhere on the net to no avail

I did, however, solve the problem, by buying an airbag module from a Mk1 RS, and swapping mine out for it. I then cleared the codes on the system and that was it Module cost me a tenner.

Maybe you could explore that avenue?

I'm intrigued.

Do these just go across two of the terminals in the socket that the old seats plugged into?

Yes pretty much, but I couldn't get them to work

The fact that there are lots in that eBay link, and they are all different values, could it be that the rating is mega critical?


Did you try different values?

If I remember correctly its usually about 3 ohms that will fool the system into thinking it has a live airbag to deal with. Maybe there are minor variations but 3 ohms has worked for me in the past as an mot get round solution Paul

I tried them in a mates lupo which had the airbag light on and we took the steering wheel off and stuck the resistor in the plug taped it all up then put it all
Back without connecting up the airbag and hey presto! Light was out!

A 2.2ohm resistor fixed the airbag light in my MG ZS when I changed the stock seats for Cobra buckets.

Maybe it was just my dodgy wiring, but i tried loads of different values around the 3 ohm area as recommended at the time. Maybe it was something to do with the Ford system, but I couldn't get it to work, and in the end the new module was a far easier solution for me, and at a tenner, saved me way more than that in my time alone

Thanks for all the help so far.
I have emailed the bloke in the eBay 100 resistor link to see if he knows the value to use.
He also sells a simulator box that can represent the various values.


These are the seats and harness that I have fitted.
The drivers seat squab has had half the stuffing removed, ( Google foamectomy ) so that I fit in with a crash hat on.

I've just bought a reset tool for the very same issue. I'm going to use it tomorrow. If it works and you promise t return it I'll stick it in the post and you can borrow it.

Ah..MX5..not 5 series..sorry its a BMW Tool I bought

I have a Maxiscan 309. It will reset errors but can't replace something that isn't there, or mend something that's broken.

Obviously I don't know which one you are buying.

555 timer or take the bulb out

In astable configuration you will have a continuous flash on and off.
In monostable the timer will flash once then off.

So I don't think a 555 will do this. Great IC and versatile in its use though.

Blond moment.

Flash once then off. Monostable will work for this. Lol
