forcata: I have this problem but with mk3. Where is the connector in mk3? I can't
James Hunt: Hi could you please help me. I am having trouble with this airbag light i
have checked the cables and cut them and reconnected. I had it checked at
renault they said i need another ecu and driver side sensor so i got one
from scrap yard. Fitted it then went to local garage to get it tested and
now it says the passenger and driver side belt sensor?? I can't get mot
because of this.
sam palmer: I've had this problem twice, each time all i did was sprayed the connectors
under both seat with contact cleaner, (can pick up cheap from maplins).
both times this has solved my issue, it just gets dusty down there and gets
in the plugs. blow into them and spray this. works for me!:) ps i have a mk
renault4mad: Hi, got a air bag light on and my snapon scanner says 36917 undocumented
code...have you had this before...
skylinefan3465: hi quick question, unrelated to airbags though.
in my clio i have the standard tape player it came with but in the boot is
also a CD changer however it doesn't work and i have no idea where to start
diagnosing this fault from, can you offer any advice??
Daniel Borthwick: Could I use a block terminal to connect wires?
Daniel Borthwick: Thanks
grozaky: very easy to make a demo on a scrap car...
thomas jervis: HI.please could you help me.i have recently bought a 2001 3 door mk2 clio
and noticed the airbag light came on and off randomly while driving.It is
now permanently on along with the SERV light also.ive checked the plugs
under the passenger seat,but in my car there are three plugs -a grey plug
with blue and brown going in and orange and grey going out.a brown plug
with blue and brown one side and light brown white going out.the other plug
is black with grey going in and thicker black going out
peugeotCitroen2CV: The time my ecu was faulty it came up as a fault code no communication with
the airbag ecu or something to that effect. I picked up a replacement ecu
in the scrapyard for £10 but the car was there because the engine had blown
it wasnt involved in a crash. What sort of diagnostics machine was used,
was it a renault clip one or universal one? Can you lift up the cup holder
to see if there is any moisture in there, the previous owner may have
dropped a drink?
charanjit1974: Thank's, the serv light and airbag light comes on. I just want to know if
you drive the car will it be safe? Also I have no idea about the airbag
deactivation switch if its pointing in the right position or not.
MOHAMMED WARIS BASHIR: I also checked that airbag malfuntion indicator to the dash was inactive to
the dash....e.g that no fault is been triggered to allow light on....the
light always remain on.....i did the reverse and generated a fault code by
unpluggin passenger plug and fault code was active also the sivnal to dash
was active.....so i now am confused to y it remains on.....i knw its a rare
case....ne solutilns i would appreciate Kind regards mohammed
peugeotCitroen2CV: It could cause the two parts not to fit together correctly and be loose
which could cause the light to come on
spicedave: 51 Reg 1.2 Clio Dynamique. I also have the problem with the air bag and
Serv lights staying on. I've done the following: Replaced the air bag ECU,
replaced the spin ring on the steering column. Someone who owned the car
before me has had a go at soldering the wires beneath the passenger and
drivers seats. I've resoldered these but I don't know if they were right to
start with. Lights still on. Could you tell me what coloured wires go to
what coloured wires. Much appreciated of any help
peugeotCitroen2CV: Sorry i dont know what it means, normally google shows up what they are but
its saying nothing for that code, does the machine not give a description
below the code? What issues are you experiencing with the car?
peugeotCitroen2CV: There is a clamp that holds the battery in place, on the clio its just a
bit of cast aluminium shaped so it grabs the lower edge of the battery, and
is held in place with a bolt. You could get one out of a car in a
scrapyard. Or alternatively try a DIY approach, get two threaded bars, bend
one end so they catch on something below where the battery sits, put them
on either side of the battery and get a flat bit of metal to bolt onto the
two bars holding the battery down.
peugeotCitroen2CV: I appear to have ripped a bit of the old carpet and used it to clean the
plug. The car was for spares and the old carpet was mouldy, and ripped in
Lippy8555: Thanks for the help, I will check this.
peugeotCitroen2CV: Is there a difference in the two wheels? You would need to check if the
connections on the back are the same, but even then I'm not sure if the
airbag modules are the same or if they are compatible with each other since
I've never been in one of the larger engined clios. Its best to check
renault forums first to see if this can be done
peugeotCitroen2CV: The diagnostic equipment helps to identify which plug is causing the fault,
but in most cases if I'm fixing an airbag light for someone i just do both
plugs under the passenger and drivers seat without using the diagnostic
stuff. It takes a bit more time doing them all, but after it you can rule
out a bad connection. When i cut and soldered the parallel wires i just
made the wires connect again (the plugs go faulty and stop the wires from
connecting right), thus in a crash it should work
peugeotCitroen2CV: Good to hear you got it sorted.
hujimwa: Yea good video helped thanks. Need my crash data erased but thats like30-40
quid with postage cheaper and easier to get another ecu then? Got new seat
so i believe its a straight swap now?
peugeotCitroen2CV: Its definatley not near the gearstick or in the cabin, its either around
the bellhousing in the engine bay, but i remember from other renaults that
its in round behind the passenger side wheel, go to where the driveshaft
meets the gearbox, you will see the switch in there, i think its a fairly
big socket 24mm.
rhino trikes: Hi Very usefull video bought a 51 plate 1.5 DCi for my Son, airbag and
service light on. Didn't see this video and followed forum advice badly. I
didn't realise the grey plugs under the seat on this clio had allready been
cut and soldered cut the black one from under drivers seat and soldered
that one. Is this just a connector (looks very complicated way to join
three wires) or have I cut out a vital component. (It's the other connector
you show in the video) car has seat airbags x2 Thx
peugeotCitroen2CV: Not many people have these i accept that, however it is possible to fix the
airbag light without the fault code reader. the wires under the seat or ecu
if fixed as shown in the video will get rid of the light, i just show the
computer screenshots to show what is going on. In them cases you can get
rid of the light without the computer. But if they don't fix it, its
probably cheaper getting it hooked up to the diagnostics machine to find
out whats wrong. I only got the lend of this machine.
peugeotCitroen2CV: The passenger side driveshaft, the switch is somewhere in round there i
dimitris kaloupis: freakS SAKE! take a piece of cloth instead cutting the foam insulation mate!
british techs and british car owners are disgusting!
peugeotCitroen2CV: You need to replace the seat airbag and pretensioner (its probably just
easier to get a seat with pretensioner that hasnt detonated, than taking
the fabric off and fixing it that way) Once they are replaced, you need to
get the airbag ecu erased, some firms on ebay can erase the crash data, or
the cheaper option is find a car in the scrapyard that isnt hit/hasnt been
in an accident and take its airbag ecu.
Anthony Anthonov: wtf .. I haven't seen so much craps in a car :) wire connector below the
driver's seat looks like to cause often problems, they should have used
more durable one ..
peugeotCitroen2CV: Sometimes second hand ones will work ok as long as the car they come from
has not been hit, but renault forums are definatley worth a visit to check
this is ok
peugeotCitroen2CV: Yep they work fine, but a solder joint is more reliable. If using terminal
blocks make sure the wires are well insulated, its best to keep individual
Stheno490BC: You are worth your weight in gold. My Kangoo had this fault, which was the
only reason it failed the MOT. I took it to a local garage who told me that
a fault on the vans engine management system meant their diagnostic
equipment would not talk to the vehicles system which meant my next step
was the dealers & a whole bunch of money & stress. So I decided to check
out Y.T. & found your video, as soon as I wiggled the connection you
indicate the fault disappeared. I can't thank you enough. :)
peugeotCitroen2CV: At 1:31 in the video the wires are soldered together showing the colours,
its orange to blue, pink to brown. Although thats just for the pretensioner
under the passenger seat, if your unsure about any of the other wires have
a look under the seat of another clio to see the colour combination. I just
cant remember off the top of my head what colours go where. Any confusion
or problems feel free to send a Private message.
peugeotCitroen2CV: The probelm with putting another ECU into the car is that the impact sensor
that detected the crash if it hasnt been replaced will still be on even
with another ecu, i would plug the car into a diagnostic machine first to
find out what impact sensor has been triggered, then replace the sensor,
and whatever airbag has went. With the parts changed see if the airbag
light goes out, if it doesn't then use the diagnostic machine to clear the
peugeotCitroen2CV: Your in NI, what part so am i, the test centres are indeed quite strict. If
your after decent auto electricians try hobson electronics they are very
good. Its possible they have wired up the thing wrong, and their diagnostic
machine may not work with the clios airbag system.
peugeotCitroen2CV: Possibly get an airbag module/ecu from a car that does not have seat
airbags, but that may pose a problem as the cars main ECU or UCH (Unite
Centrale Habitacle, or ecu for non engine stuff) may not work with an ecu
from a car of different specs, its worth trying renault forums to see if
its possible to put an airbag module from a car with no seat airbags into a
car that had seat airbags. Unless, is the seats you put in airbag equipped
seats that have broken sockets by any chance?
nasir n: Drivers side and passenger side it says short. Circuit ..how will I fizz
that ..any ideas please
Lippy8555: I've plugged mine into a diagnostic kit and the fault code reads something
like "driver side airbag short circuit". Does anyone know what the cause of
this could be?
peugeotCitroen2CV: When you say meter states do you mean diagnostics machine? If it has
specified the passenger seat then its most likely the black plug as i have
shown in this video, cut one pair of wires and solder one pair at a time so
they dont get mixed around
James Forrest: stupidest place for a piece of electrical equipment ive ever seen!
peugeotCitroen2CV: Yes, it should be the same on mk2 clios between 2001-2005
Dan Hughes: Keys not in best condition but a auto locksmith came out to reprogram it
and the key was fine. He couldn't read the car when he put the lead in the
obd socket but the key is defiently working and programmed.
paul oconnor: Yes it states code which is passenger side airbag had it in garage and they
didn't even know about this clip lol so basically cut top and bottom wire
one at a time and soldier one at a time
Dan Hughes: I did, they could not read the clio, the key was programmed as he tested
that, and nope
Nasir Mahmood: Hey I done that and the lights not going out clear codes with s nap on and
now getting p3507 fault code
Dan Hughes: Could you please advise
peugeotCitroen2CV: You might be best going onto renault forums, as they might know more about
this particular issue
BUNGLE BEAR: hi, same problem with my 06 reg megane. I move the drivers seat and light
comes on. is it just a case of disconecting battery and chopping wires to
solder. crapting my self incase air bag goes off. thanks
peugeotCitroen2CV: The purpose of the plug is to connect the wires for the pretensioner and
seat airbag up with the airbag wiring loom in the car, because of how cars
are made plugs are used because this is the quickest way on the assembly
line to make the connection. The plug does nothing more than connect a
series of wires together, so it can be removed and replaced with soldered
connections if it is giving trouble. The soldered connection (if soldered
well) is much more reliable than the plugs.
m1tnick: Thanks again for saving me some € :) This time I'm trying to find why my
rear lights won't turn on when I put the reverse gear. I believe there is a
bad contact somewhere under the gear level.
