    I have taken the double passenger seat out of my 2009 Citroen Relay to fit a single seat, now the airbag warning light stays on. (If I plug the double passenger seat back in again it goes off)

    Does anyone know if there is a fix for this please?

    Our Nissan Terrano car developed this problem. We put up with it for weeks, knowing it was because we'd had a flat battery ( kids left internal light on and we went off for the weekend in the MH:RollEyes:) Nothing important.
    We were told, by a mate who works for relay, it needed to be looked at by Nissan diagnostics.
    Ralph looked up the problem over the net.

    Someone had posted a solution which was :-
    Turn ignition on wait for red light to flash for 7 seconds ( air bag red light that is !)
    turn off ignition
    repeat 3 times.
    It worked , seemingly it re-sets everything. So much for a diagnostic check up . Its still working........

    dont know for sure, and airbags are dangerous things, but it could be related to seat occupancy.



    no-one in the seat and in the event of an accident the airbag wont deploy for that seat.

    i'm not suggesting for one minute you would but DONT try to deactivate the airbags..without techy knowledge they WILL activate.

    can you trace the wiring within the seat and find the sensor then transplant it into the new seat ?

    not only does the light mean a fault exists, it means ALL the airbags DONT WORK AT ALL as its registering a fault in the system.
    also an MOT failure point.

    that wont cure the fault if the seat sensor is missing, as in this case.:thumb:

    But if ever the light on the dash starts flashing, after a flat battery , try it , it worked for us and saved us loads of ££

    you failed to say whether your single seat is the proper single seat that is fitted to this model and if you plugged in the new seat , obviously you have to have the correct seat and sensor fitted

    Sorry I should have said. There is only one airbag, which is on the drivers side, nevertheless the airbag and passenger seatbelt warning light stays on when the original double passenger seat is unplugged, and the dashboard panel says 'consult handbook' which tells you nothing. When the original double passenger seat connector is plugged back in all the warning lights go out again, irrespective of whether or not anyone is in the seat.

    I don't have a single passenger original equipment seat with a sensor, the single passenger seat I was thinking of installing does not have any sensors. Just had a look at the original double passenger seat and it appears the sensors are sewn into the seat so I would have to butcher the original double passenger seat to get them out. :Blush:

    WARNING
    A special procedure is reqd to disarm your airbag before ANY type of work is undertaken on seat/seatbelt systems even removing/re fitting seats can cause an unexpected deployment, a very dangerous and expensive mistake
    Under no circumstance start prodding Air bag circuitry with meters or probes without fully disarming the system
    An illuminated air bag light is not an MoT failure
    seek expert advise there is a solution that an auto electrician can do for you

    now this'll get you thinking/worried (delete as appropriate)

    that could be one of the 'secret' procedures to disarm the airbag system...:Eeek: no wonder the light went off :Laughing:

    same but opposite

    I have the same problem with my 2007 ducato... i fitted a double crew cab seat so that my son could sit up front.
    The air bag light came on after removing the single seat.
    the van is in north east truck and van gateshead having remedial work done for the judder.
    They are having no luck with clearing the fault and say they have nad no luck for a answer from italy?
    They told me that it is a MOT failure when the time comes.... very soon April:Angry:
    i was wondering if i fitted the old seat back in if the fault would clear or could be cleared
    my van has only the one air bag

    Yup some systems can be re set using that method
    Disconecting and or probing may cause spikes:Eeek:
    and that definatley smakes em go BANG!!!!!!!!!!!
    Any recovery driver will tell you
    If the air bag has gone off put a plasic cover on the seat before getting in:thumb:
    more than likely the seat will be WET or worse:Eeek: and im not talking sweat:Rofl1::Rofl1:

    When I ordered my new Vito I specified 2 seperate front seats but the salesman only had his selling ears on and it came with a bench and drivers seat. They rectified the mistake (after a 7 week wait) but the airbag light was on when I drove it out of the showroom. It went back in for reset but it couldn`t be done as the ECU was stilll thinking it had 3 seats, so a new ECU had to be fitted.

    Don`t know if this would apply to your vehicle but a possibilty.

    I still have my original seat and i have just had a quick look
    Traced the plug lead from the seat to a seat belt sensor unit next to the pre tensioner.
    looks if the crew cab seat is wired to take 2 outputs while the single seat is wired for 1.
    Still strange that a large main dealer cannot sort the problem out?
    i might take the wiring from the single seat and fit to the crew cab..... but not ideal?
    any thoughts as i don't fancy splashing out £££££ for a new ECU
    This might only be for a year or so as the son is 17 soon
    and wont' want to come with us

    My jack russels would kill 'em. :Rofl1:

    it was just something that passed through my mind.
    worth checking out though just in case.

    im sure the official disarm procedure would be a little more complicated than a few key turns.

    you could ask at a body repair workshop as they will disarm the bags to do repairs to accident damaged cars.
