Has anyone ever had to turn off an SRS airbag fault tell-tale?

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.

Many don't deploy for any number of reasons.

Its also illegal to just clear the fault without fixing the problem if
it exists.

Can you cite the statute?

Construction and use says some cars have to have airbags and that they
have to have working warning systems.


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
you cite the statute that makes it illegal to drive a car with the
air-bag light disabled?

Do you think its legal to drive a car that you know will fail the MOT?
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.


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

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.
