Pordave Posted August 4, 2023 Report Share Posted August 4, 2023 Help…. I have a fault with my horn going off randomly until the horn steering wheel pad is moved it’s very loud and non stop. Having watched you tube I know how to strip and cure the problem with O rings but need to know the correct key position to a) disconnect the battery without the alarm going off. b) to avoid having to take the car to a garage to get the airbag light reset if I disconnect it. c)anyone know what size O rings to use?

Paul P Posted August 5, 2023 Report Share Posted August 5, 2023 It was my understanding that key to 1st position to prevent alarm going off. I have also read that turn to 1 and then turn off leaving key in the lock is the “proper” way. ii think most people do the key to 1 thing. leave the battery disconnected for 15 mins before poking the airbag you should get an airbag light as long as you don’t power up with it disconnected. don’t know about o ring size but I tend to buy.a set of various sizes when getting anything like that.

Corrected above for accuracy... Turn to the first click position. Disconnect battery. As long as you don't apply power when the air bag is disconnected you will NOT get an airbag fault. 1 Quote Link to comment Share on other sites More sharing options...
Richard Hamilton Posted August 5, 2023 Report Share Posted August 5, 2023 (edited) @Paul P is correct here. Switch ignition on, then off, but don't remove the key, before disconnecting the battery. The alarm uses Terminal 86S (Key in Ignition), not Terminal 15 or T86 (Ignition on) to detect if there is a supply to the alarm siren, allowing the battery to be disconnected. Leaving the ignition on also works, but you get a bigger spark when you reconnect the battery. 😀 Edited August 5, 2023 by Richard Hamilton 1 Quote Link to comment Share on other sites More sharing options...
Everywhen Posted August 5, 2023 Report Share Posted August 5, 2023 The O ring fix wasn't that successful for me, horn was still far too sensitive. Swapped the steering wheel for a 3 spoke in the end. Quote Link to comment Share on other sites More sharing options...
Pordave Posted August 7, 2023 Author Report Share Posted August 7, 2023 Cheers chaps for the replies. The first locking part of my ignition switch is so worn that position 1 is pretty indiscernible from NO instrument lights being on. To position 2 with full Blackpool illuminations. So I’m pleased that so long as I leave the key in after turning ignition fully on and then off, or leave Blackpool illuminations on and then disconnect the battery that I can avoid having an air bag fault light even if I have to disconnect it.

Maybe time for a new ignition switch: They can cause all sorts of odd electrical issues if they fail. Edited August 7, 2023 by ½cwt Quote Link to comment Share on other sites More sharing options...
Pordave Posted August 7, 2023 Author Report Share Posted August 7, 2023 Re ‘Maybe be time for a new switch’ I replaced the electrical one but not the mechanical one. if SWMBO indoors would allow I’d have a new car and sod the switch!

Daboy3000 Posted August 8, 2023 Report Share Posted August 8, 2023 I did the O-ring fix ad now I need to press really hard, I used two O-rings per corner. 8mmx3mm https://www.ebay.co.uk/itm/184955101030?var=692874981696 Quote Link to comment Share on other sites More sharing options...

To be clear the ignition switch to pos1 then off is to stop the alarm going off when you disconnect the battery. AIrbag fault lights are avoided by NOT reconnecting battery (or rather not reconnecting battery and switching ignition on) with the airbag disconnected. 1 Quote Link to comment Share on other sites More sharing options...
