If I go to a Volvo main dealer they'll take me to the cleaners for this I

this myself if it's at all possible!

Has anyone ever had to turn off an SRS airbag fault tell-tale? There
might or might not be a genuine fault, but I don't care either way. Being
of a certain age I just want the warning got rid of. The car is a 2008
Volvo V70 if that makes any difference.

I have an OBD cable and dedicated software for VW/Audi group cars, but I
have also used it in 'generic' mode on the neighbour's Nissan.

You can clear any outstanding 'trouble codes', whether that would put
the warning light out on the dash, who knows, but you'd hope so ...

There is a good chance the system will log the fault and there will be
serious trouble if someone gets hurt because the airbag didn't deploy.
Its also illegal to just clear the fault without fixing the problem if
it exists.

It would also be illegal to drive the car in the UK AIUI as it wouldn't
legally pass an MOT.

Again, construction and use is a separate consideration to the MOT. Can

Most unrepaired faults, even if temporarily cleared, will simply turn
the relevant warning light back on.

They can prove you know if the fault has been cleared without the
diagnostics being run. Just because you have an MOT doesn't mean its
legal to drive a car.

Maybe, maybe not. Unless you know why it came on you don't know if the
airbag will deploy when it should or if it will deploy when it
shouldn't. You would look pretty stupid if it went off while you were
doing 70 on the motorway or leaning over to clean the screen.

Just think of why they require a warning lamp.

There are some MOT failure faults which make it illegal to drive the car
and other MOT failure faults that don't make it illegal to drive the
care. The MOT rules have just been modified to clarify that you can't
take the car home with some of them. (It may be that a fault that did
not make it illegal to drive the car under these rules, which relate to
driving a dangerous vehicle, might nonetheless be offences to drive with
under other legislation, such as some light faults.)

Yes, some cars have to built with features. Disabling them afterwards
doesn't mean it is illegal to drive the car.

The current VW emissions fiasco is a prime example. Is it now illegal
for VW owners to drive their cars? Have you seen any prosecutions.

Hence why I asked for a statute, which you will simply be unable to provide.

You do know what a 'warning' is? Don't you? A hint, it's a 'warning'.

Is driving a car with an ignition warning light on illegal? What's the

Almost certainly the case with aftermarket low cost diagnostics.

Pre-OBD it sometimes required another specific manufacturer plug in
data cartridge that only covered the airbag function and nothing else.

This used the same basic handheld diagnostic device as used for the
engine still plugged into the same vehicle diagnostic socket using a
shared pin on the same vehicle bus with each control unit responding
to a specific poll. .

After serious thinking Dave Plowman (News) wrote :

True of most of them. Mine needs separate systems for OBD, SRS, FBH,
ABS and etc..

It appears the software can reset airbag/SRS warnings on VAG cars (which
the software is intended for) but it may be that it can't do the same
for 'generic' cars where it only does the more standard OBD functions.

Its not as simple as €œjust disabling the warning light€�. All the warning
lamps should illuminate when the ignition is first turned on. If a lamp for
a safety critical component doesnt light up when it ought to, it
constitutes an MOT fail.

The airbag deployment circuit is tested each time you turn
the ignition on. I suspect at best, you could disable it
until next time the ignition is turned on.

Airbags are generally rated for 10 year life, and it might
be that yours has detected that it's gone over 10 years old.
Check if the service schedule for your car expects replacement
after 10 years.

That used to be the case, it was the expected life at that time, but
now they are suggesting an indefinite life for them, or until deployed.
Have you ever found a source for replacement bags for a 10 year old

Why would they stock air bags as separate spares? Usually airbags would
be sold as part of an assembly. For side air bags in the seat you have
to buy a NEW seat. For a 10 year old car the cost of new parts alone for
replacing the assemblies with air bags is uneconomic. The damage done by
airbag deployment is usually enough to write off any car over 10 years old.

Dash is usually destroyed - huge amount of labor to replace the dash.
Airbag deployment usually cracks the windscreen if there's a passenger.
How many airbags? 2 front + unknown number of side bags.
Collision sensor is not re-settable and has to be replaced.

And then there's still the damage from the accident that triggered the
airbags.

Even if it's not your fault you need a replacement car.

If it has air bags your car better be worth over £10K to be repaired by
insurance, cos this will be £5K by the time an insurance approved rip
off repairer has had their cut.
New passenger air bag will come as part of the dash assembly. £1000?
New drivers air bag will come as part of the new steering wheel. £300?
New seats will have side airbags in them. £1250 each (ford focus) £1500
if heated and £2500 if motorized?

I was responding to the manufactures original suggestion of the need to
replace them after ten years, rather than after deployment. Nobody
stocks them, even for new cars - so far as I am aware and the latest
advice is that they have an unlimited installed life anyway.

No, you have to go to the local scrap-yard and buy a ten year old seat
with the side airbag and the seat-belt pre-tensioner for £20, and then get
someone to clear the 'airbag has been detonated' setting in the ECU. And
wonder why the French don't have the Secondary Restraint system check if
the primary restraint system is not in use because there is no passenger.

The airbag light sequences for each car are published. Requiring an
engine start to extinguish an airbag light would IME not be a valid
sequence.

The Other Mike brought next idea :

None the less - I understand that doing such resets the warning light
on my car, not that I have ever needed to. It will be recorded in the
SRS ECU though, as a fault.

Usual fault is moisture getting into the floor mounted ECU, replacement
of which requires coding and poor connections to the seat / head
airbags, due to movement of the electric seats.

Historically you could have done what the hell you liked until the light became
a testable item some 5 years ago iirc.

The testing station I use has a number of huge posters on the wall of the
testing bay, kerb weights for calculation of brake efficiency is one, and one of
them covers the warning light sequences for what must be hundreds of models of
car. Clearly they are not part of the MOT testing handbook but they wouldn't
just have them there to make the walls look pretty.

You probably need to find the local specialist who has the gear to read
the fault from the SRS ECU, work out which plug to clean, and then maybe
reset it if it doesn't automatically clear on the next self-test.

(Engine diagnostic or service warning light is usually easier to clear).

I recently replaced a sensor on a Ford as the Airbag light came on.
Corrosion had caused a pin to come away, and the sensor presumably
failed its self-test.

This was using Forscan. I have no idea if there is an equivalent for Volvos.

You don't normally need any equipment to clear a service warning light.
In most cases its hold a particular button(s) in while turning the
ignition on/off. Google will probably tell you which if the
dealer/manual won't.

Example for an astra..

Turn the ignition on, one position before starting engine.

Press MENU button until on the display will appear vehicle information menu.

Rotate the button which has on it two arrows one up one down, is located
next to the MENU button, until message Remaining oil life is displayed.

Press and hold button SET/CLR, press brake pedal and hold them for about
15 seconds.

Release SET/CLR button and brake pedal, switch ignition off.

Have you ever heard of a capacitor?

I'd be very surprised if there were any in a car capable of retaining a
charge sufficient to trigger an airbag after 1/2 an hour. ;-)


certainly, but it is why you wait, just in case.

Look up supercaps, they are a large capacitor with a remarkable qualities.

I also think 1/2 an hour is a long time, and indeed suspect it is more
likely seconds. However when the consequences of getting something like
this wrong, even I would leave and make a hot drink before returning.

Dave Plowman (News) laid this down on his screen :

It is quite feasible to have them capable after much longer than 30
minutes, but they design them to be discharged within 30 minutes to be
safe. An airbag being triggered can do some serious injury.

Has anyone ever had to turn off an SRS airbag fault tell-tale? There
might or might not be a genuine fault, but I don't care either way.
Being
of a certain age I just want the warning got rid of. The car is a 2008
Volvo V70 if that makes any difference.

Do you trust anyone that posts cr@p like this..

"A very useful tip, thank you. Before fiddling with the connector, you
need to leave the car switched off for half an hour to discharge any
residual current in the electrics. Otherwise, you might trigger the
airbag. "

where it goes after 30 minutes?

None of those with enough voltage on them
to bite you in the airbag system of a car.

No-one has mentioned getting a shock from one, they have enough energy
to fire the airbag, which is the very real danger, an airbag has plenty
enough energy to kill or maim an unbelted person.
