Title: Air bag light.
Post by: dave-b on 07 November 2011, 00:13:09
I have a fault on my 2001 3.0 elite that will become a problem with the new MOT regs that are due to come in 2012.
The  airbag warning light is on, due to a faulty child seat detector transponder in the front passenger seat which would cost approx £300 + labour to replace.
Does anyone know how to disable/bypass this sensor so the airbag light will work normally ?  I have been told it is programmed into the ECU and cant be removed, but it is a rare option, not many Omegas had this fitted.

i have seen them on and mig in scrapyard, there is some that have a switch in the glove box but only seen them on vectra's, think the sensor can be turn off with a tecII,  has it on my com but ask some one on here with a proper tecII they may beable to turn it off with there tecII.

It may be easier to get a replacement ECU from a "standard" car. It wont be prorgammed to look for the seat sensor and as such wont be bothered if it isn't there.

Anyone breaking a FL car should be able to help.

The airbag ECU is located at the rear of the centre console - but you will have to remove the console to remove it.

Treat an airbag ECU with care, dont drop or manhandle it. Also, disconnect the battery for at least half an hour before doing anything in this dept.

I think you will find that an airbag light on will fail the current mot

I may be wrong,but I think you may be able to unplug the sensor at the side of the seat and then have the light turned off via any device which is capable of turning it off. Istr thats what I did with mine earlier this year. :-\
Wait for others too confirm or not though,as airbag related things are not something you want to just dive in and have a go. ;)

Not according to my MOT guy, the new regs come into force on 1/1/2012.

As for removing the fault with a Tech2, that doesn't work, even with the seat plugs undone, the light goes out then reappears after a few seconds.
Perhaps changing the airbag ecu would be the best option to try first, I can see a trip to the breakers yard coming up!
Any other comments would be most welcome though, guys.

I stand corrected, the airbag light is not currently an MOT failure

Yep, if the ABS ECU is configured  for that sensor to be present, it will always flag up a fault. AFAIK, configuring the ECU is a one-shot operation when the ECU is new, although I've never actually tried too hard to reconfigure one with a Tech 2..

The airbag ecu should certainly detect if a sensor has failed or is missing, and will illuminate the bulb, the "off" switches usually substitute an alternative "load" to keep the ECU happy

or it could even be that it has stored some crash data (pothole / speed bump can do that) which Tech2 will not reset either (a solution for, I`m currently developing here)

Actually,Ive just offered the OP an ECU if he needs one,but I believe I sent them both to you a few weeks ago. ::) ;D

Albs, I can have a look through the charred remains, to see if there is a good one left if needed,  :-X

but my gut feeling is that the fault lies elsewhere, or even with the disconnected sensor

Dont worry about it Dave.Im sure there are plenty more floating round on the forum if he does need one,or wants to try one to eliminate it. :y
Did you get anywhere with your experiments on the ECU,s.  :-\

A local member has a similar problem, so I need to investigate a bit further...

What about linkin the Airbag bulb to another bulb like the engine light one, or remove it completely?

I'm gonna do something like that when i'll remove original seat with airbags.

As of January, that will be an MOT failure :y

Well, if you link it to the engine check light, it will go on when you turn the key then off when you start the car, i can't see how it would make the car not pass the Mot.

Cos the lights dont go off at the same time, making things like this easy to spot.

So, your happy to disable the entire airbag system, then hide the fact?
Rather than illegaly butcher your speedo and invalidate your insurance, why not just fit dummy airbags (resistors) where the seats should be to keep everything else happy.

somebody remind me never to buy a car from  Modena or even go there if this is what they do to their cars  :o :o  take it there is no mot's there either or insurance ???

How / where to find those resistors?

Could save me TONS of work.

Fiend, well, DON'T buy cars from Modena, or at least the used ones from dealers, all of them have kinda double of the Kms they have on the tacho.

Aaand... if you'd read well be-fò to shot stoopid sentencies you'd read this car is my toy, not my daily driver, so who cares if i'll have to find a "slimey" way to pass the MOT, insurance would not be invalidated in any case, we have "renounce to driver's liability" here, you pay kinda 80 euros more every year, if yer tires are worn / wrong measure / slick tires and you crash in another car insurance doesn't care about it and pays the same, same story for coilovers, exhaust and stupid airbags, also because here in Banana Republic ANY modify you do to your car is ILLEGAL, there's no way to make it legal, so who gives a shit, just hide it as good as you can and enjoy.
I say stupid airbags just cos's i gonna fit 4 point seatbelts and bucket seats, son an airbag is gonna worth nothin on that car.

Would he not be illegally butchering his srs system by fitting resistors?
If the car should have side airbags from the factory, and they are removed, would that not invalidate the insurance too?

is it driven on a public road, if it is then your a danger to yourself and other road users, and by the way i dont "shot stoopid sentencies" whatever that is meant to be!!!
if and only if you are using the car as a track car and towing it to the track then you can do what you like to it, but you havent mentioned that in your previous post!!!
what is annoying that you try to give totally illegal advice (in this country) to someone who wants to cure his fault within the laws i.e a contentious law abiding motorist!!!!! who doesnt want to be found out by the MOT testers as having bodged his car!!!

sorry guys rant over  :y

Play nicely all....

There are ways and means, and different customs etc....

If changing seats, some airbags better than none etc...
The airbag ecu needs to see a 3 ohm (iirc) load, so you just need the appropriate resistor to provide that.
Any auto electrician should be able to supply one I would have thought.

Yes, that should also be notified to insurers in the UK here.
Which is best  :

Ive fitted new sports seats, which obviously dont have airbags, So I have added dummy load to keep the SRS happy.   Fine, no problem sir, thanks for letting us know.

-v-

after a crash, investigator sees
fitted new sports seats, and hidden the fact by modifing the warning light = Your 'breaked'

Gold.

I assume this is for seats, same load for the steering wheel?
