Renault Clio Airbag Light Fix




What do you think about this video?

forcata: I have this problem but with mk3. Where is the connector in mk3? I can't find it.

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. 

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 other places.

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 think.

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 blocks separate.

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 crash data.

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

nasirm438: 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.

Alex Boothby: Hi buddy, great video. Do you know what I should do? I hit a curb and the Drivers seat airbag went off. I then replaced the drivers seat and a the ecu with ones from a scrapyard clio (it had not had the airbags go off) but the light Service light and the airbag light is still on the dash. The garage put the seat in, but don't know why the lights wont go out. Any help you could offer would be fantastic. My MOT is soon and I know it wont pass!

paul oconnor: Hi I have a Renault Clio dci 01 plate air bag and Serb light have come on meter states passenger side under neath seat there's is the very small black plug do I cut this and soldier

peugeotCitroen2CV: This car was for the scrapyard, i was ripping out the carpet and insulation anyhow as it was mouldy and smelt awful due to the fact the previous owner left the car sitting for over a year with leaky door seals. I should have got a cloth to clean the connector for the video to give a good example, sorry about that.
