Evening 🙂

Sorry for this being my first post an asking a question, but now glad to be here.

Our 2018 has an interment issue with the airbag deactivate light coming on. Happened a year ago and turning the switch off/on a couple times in the glove box would resolve it. However, it's now coming on more often (sometime does, sometimes doesn't) and turning it off/on doesn't now clear it. No errors codes when I did an ODBC scan.  Replacement switches are only £30 but I'm struggling to find a guide on how to get the switch (remove the trim, etc), despite searching on here and on YouTube. 

Anyone else done a replacement and know how to get to the switch so I can swap it out? 

TIA :-)

This is quite unusual. The whole of the safety restraint system (SRS) is designed to fail safe. That to me would mean the passenger airbag would default to 'on'

I suspect that the deactivation key-switch may not actually be the fault. They are only a press fit from the front. To remove them open the glovebox and fully drop down the opening part as if you were going to change a fuse (see owners handbook for details). you can the reach up behind the switch and squeeze the sides to depress the two plastic lugs. The switch can be pulled forward. Carefully release the latch on the wiring plug and pull it out of the switch.

Many thanks 🙂    Re your first point, I agree, which makes me feel like it could be a switch issue, and also that turning the switch on/off did resolve it (for a while). We will see once I swap it out 🙂   I'll get the switch out (thanks for the advice on how to remove it) and then order the correct replacement up. I'll post the outcome back here.

Just been out and lowered the glove box and managed to pop the switch barrel out, though the wire is so short that the photo below shows the furthest I can get it out and I can't work out which part is the latch on the wiring plug and which way to move it? Nothing seems to want to move and I'm conscious that I don't want to break something off in my ignorance 🙂

 

 

I see from the part number it is D3L0J-14B268, would a D3L0E-14B268 work, or does all the reference need to be correct?  Seems to be lots of them end in 14B268, but the first part has different letters at the end of D3LO?.  Not sure what the ford part number system is. Any insight/advice on this too would be great 🙂

Actually - only £22.94 direct from Ford (after putting my reg number in, so should be the correct one!)

From memory, I seem to remember that you need to use a little pick, or a very small screwdriver and flick the red bit up out of the connector. Then you can press the release latch.

Ian @iantt might be able to tell how the latch unclips.

That's correct.  The red part is a locking tab.  Pull that right up.  Then press the black bit in the middle to release the plug.

Many thanks lads - really appreciated, glad I stopped trying things out myself as I'd never have tried that one!

Replacement ordered and I'll swap them out when it arrives and fingers crossed it resolves the issue.

Well, I'm an idiot. No idea what I was thinking considering I've been driving for 30+ years and have had a lot of different cars, but for some reason I thought the airbag warning light on the dash was the passenger airbag deactivation light - really have no idea why I thought that.... bizzare....

Also no idea why turning the airbag deactivation switch on and off seemed to turn off the airbag warning light. Anyway, installed the new switch, no warning light and then the airbag warning light came back on again a few days later. So as you have said in your reply, the deactivation key-switch wasn't the problem at all, and it was just a co-incidence that that turning it on/off at various times coincided with the warning light going off.

Probably the intermittent warning light is down to the wiring loom under the driver seat - so I've given that some movement attention (without taking it apart), and the warning light is off and hopefully it stays off. No errors codes when doing an ODBC scan, though not 100% sure they would log as one anyway?
