peugeotCitroen2CV: No worries, glad to help.
Taihai Chen: That's very clear and problem-solving. Your comments are very much appreciated! :-)
peugeotCitroen2CV: I made another airbag video "Peugeot 406 Airbag Fault Fix" which is much clearer than the clio video at showing the process of soldering the wires together if its any help, even though its for a 406 the whole approach to solving the issue is very similar to a clio
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.
Taihai Chen: Thanks for the reply. That's very kind of you. But still, not quite sure about the plug. I appreciate the fact that the plug could go faulty and stop the wires from connecting right. But if cutting & reconnenting the parallel wires could also do the same job when crash happens, then there's no point of deploying the plug in the first place.
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
Taihai Chen: Hi Peugeot. Thanks for the video. My car has got airbag light on constantly and failed MOT test recently. In my case, my car is a bit diff. to your demonstration one. It has the seat airbag, that means the red plug has its own use. That leads me to two questions: (1) Not sure which plug (red for seat airbag, and grey for seatbelt pretensioner) has caused the light on. (2) In your case, you cut and soldered the parallel wires. But does it mean the pretensioner would fail in case of car crash?
Daniel Borthwick: Thanks
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.
Daniel Borthwick: Thanks a lot, also my car failed mot for battery not being secure,how could i secure it?
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
Sam Lamont: Hi Peugeot , would this work to remover the steering wheel airbag, thinking of putting a 197 wheel on my 182
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.
Daniel Borthwick: Could I use a block terminal to connect wires?
peugeotCitroen2CV: By the way you described it your car has a few plugs under the seat, do you have side airbags in the seat?
If the plugs are loose (you cant tell exactly what one without a diagnostics machine) then cut one pair of wires that are parallel to eachother in the plug ie the one going in and one going out, do one pair at a time for the affected plug.
peugeotCitroen2CV: Solder shouldnt come off if you solder it right, soldering takes a bit of practice to get right, once a good solder connection is made put the heat shrink tubing over the connection (it needs to be slid on before connecting the wires) and use heat to shrink it, alternativley insulating tape.
thomas jervis: I don't know which wires to solder together to make the light go out,there are wires under the driver seat with same colour plugs but more wires again,could this need soldering also? any help would be much appreciated as ive mot coming up soon and would like to sort it out thanks.
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
paul oconnor: How do u ensure soldier doesn't come off if this happened would airbag go off
paul oconnor: It has service light on and airbag even with engine running
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
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
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: good stuff
charanjit1974: Thank's mate, I will check the switch, I have found the code for the car system, at last i have music.
peugeotCitroen2CV: Serv light and airbag light normaly come on together, it could be cured by following this video. The deactivation switch on the passenger door will either point to on or off.
If you drive the car with the light on its still the same car, the airbag might not go off in an accident thats all.
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.
peugeotCitroen2CV: The radio code comes in a card found with the books that come with the car, unfortunately as the clio is an older car and likely to have had many previous owners the books and card can go missing, as with the code.
I think there are sites on the internet that can retrieve a missing code its worth a google to find out, otherwise car audio specialists normally offer a radio decoding service
peugeotCitroen2CV: Do you mean the passenger airbag deactivation light, or the general airbag fault light?
an airbag light (which normally appears with the SERV light) means there is a fault with the airbag system, it might not go off in an accident.
Have you checked the passenger airbag deactivation switch is still pointing to the on position
peugeotCitroen2CV: I speed these bits up otherwise the video would be really long, and its only the boring bits that get sped up, there is no point in watching a ratchet operate at normal time
charanjit1974: Also radio code, does anyone know where to find it?
charanjit1974: Hi Can someone help me out on something, I have a renault Clio and the SERV light has come and the passenger light is it still safe to drive? with these lights on? please help. Thank you.
Ann Teak: I cleaned a coffee tainted ECU and connector with lots of WD40 and a very small brush. 30 min job, all working. All you are doing with that connector is pushing dirt into the holes. Instead it should be sprayed with WD40 and then blown out from the wire end with an air duster.
Ann Teak: The speeded up parts are really bloody annoying!
peugeotCitroen2CV: Thats it, take the battery out wait a while for any charge to go away, then chop and solder one pair of wires at a time
DAMIAN KELLY: 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
James Forrest: stupidest place for a piece of electrical equipment ive ever seen!
peugeotCitroen2CV: i just went to my local scrapyard where they let me try the replacement ECU there and then before buying it which was handy.
But if your buying one on eBay try and get one from the same year, same spec (ie if it has seat airbags or not)
Harry Forman: Hi I need a new Airbag ECU for my clio. Looking on EBAY there are lots of different ones with different numbers does it matter which one I buy or will they all work?
peugeotCitroen2CV: There are very few car companies who do it differently, its quicker on the production line to plug in the seat connector than to start soldering them in.
grozaky: mercedes benz ad VW has similarly crapty connectors. hail for good old hardwiring:)
peugeotCitroen2CV: £700 for an airbag, did someone in the garage accidentally quote the price of a clio :)
gravydavie1888: Thanks, my mother was quoted £700 for a new airbag !!! The first part of this video fixed it. And I made sure everyone I talk to knows about the garage that gave the quote !
peugeotCitroen2CV: You might be best going onto renault forums, as they might know more about this particular issue
Dan Hughes: I did, they could not read the clio, the key was programmed as he tested that, and nope
peugeotCitroen2CV: You might be better taking it to an auto electrician that can work on the car, these clios are not all fully compatible with obd readers and ideally the renault clip machine is needed.
Did you spill any drink round the key barrel?
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.
peugeotCitroen2CV: Other than the airbag ecu the only other electrical thing in that region is the obd socket (found by lifing out the ash tray).
The immobiliser reciever is around the key barrel, what condition is the key itself in?
Dan Hughes: Could you please advise
