Air Bag Deactivation - Fuse?

[The Scoop]

Hi,
I want to deactivate the passenger side airbag on my 2000 Roadster and since there isn't a switch I fancy doing it by removing the fuse.

Any ideas where I can find it and has anyone else done this??

Of course, if there is a better way, please share!

Thanks,
Steve

I think you have to go back to Toyota and ask them to deactivate it

[Anonymous]

first question is why would you want to do it. also not sure if it would work but you coould switch one of the wires to the airbag to disable it as it would then not be able to make a circuit to the air bag if it wanted to set it off.

It's been done before to allow children in the front seat.
I'm sure I've read before that's it's not just as simple as removing the power or firing cable and that it has to go back to Toyota to be deactivated.

I thought it wasn't possible to deactivate the airbag for the passenger side - hence the no rear facing baby seats etc!?

Also, would removing the fuse not deactivate both!?

Im pretty sure Ive read somewhere on here that there is a connector around the glovebox somewhere that disconnects the passenger airbag.

Theres some more info here

and I think I've got a marked up circuit diagram somewhwere if that would be any use

I really thought this was going to be a simple job, it would appear I was wrong!!
I'd like to disable the airbag to put my sons front facing child seat in, but also I'd like to enable the airbag quite quickly afterwards for use of the car when he isn't in it.

Thanks for the responses, however has anyone actually succeeded in doing this??  There seems to be plenty of ideas, but noone saying that they've actually finshed the job.

Anyone?

I haven't done it myself as I have no need, but in the link I posted it tells you exactly which wire to disconnect, how much easier do you want it. if I needed to enable and disable it I personally would put a simple on off switch to that wire and fit it in or around the glove box.

It is ok (although not ideal) to put a front facing child seat in the passenger seat, the owner's manual devotes several sides to how to do this correctly. Basically, you push the seat back as far as it will go, and also tilt it right back. My 2 year old often drives in the car with me, as he much prefers it to the 207.
Failing that ( my friend advised me about this ), you can get a friendly mechanic to install a switch for you - but I don't know how this would sit with the insurance.

I am sure that the link given would disable it,but nobody is willing to test that fact.

Interesting point, food for thought.

Thanks everyone.

MR2 Spyders sold in the United States have an ignition key operated switch in the glove box for precisely that purpose.
It should be possible to install one into a Roadster.  The ignition key operation may be a problem, though.

My exploded drawings are for a left-hand-drive car, and say the part numbers are:
69065-17020  Driver's Side
69065-17010  Passenger's Side
One of these should do the trick.

I fired an airbag off in the garden once. I was interested in the effect that removing the head restraint would have on a persons head when the bag deployed. It blew a melon about 5 metres!

I had one deploy when I crashed an MGF. I passed out and it cracked a bone in the chest. (That could have been the seatbelt though).

Holy thread revival batman!!

I've just put our little one in the Emu (2005 MR2) and realised this one does not have a passenger airbag switch!!
Now from reading other stuff on here I'm partially confused because the 2002 MR2 I've just sold DID have one.
How did that one end up with one?

Found a switch on eBay for 18 quid...and 32 postage!

So, was the switch ever officially part of the UK version?

afternoon all, thought I'd have a go at reviving this thread as I thought of a simple fix for this that I've not seen mentioned..

I'm in a similar position to many, in that I had assumed there was an air-bag disabling switch to allow use of rear-facing child seats, and starting next week I'm going to need to drop our little girl at the childminder a couple of days a week.

Anyway, If you look underneath the seats there is a wiring connector to the seat, and I'm assuming it must contain a couple of switch outputs:  1 to signify weight in the seat, and 1 to signify that seatbelt is on.

So question is this..   if you just disconnect the seat connector, would the car assume there is no passenger present and not fire the air bag on that side in the event of an impact?

I had a look at the seatbelt switch wiring diagram many moons ago. I don't recall it being linked to the airbag circuitry, just the seat belt tensioner, the buckle, and the flashy light.

I think it's a very large assumption to make (and wrong in my opinion) that airbag won't trigger if passenger seat isn't occupied.

I agree its one thing to have a US spec car with a proper switch from the factory. Another to go playing with the airbag wiring on your own. Not a chance i would take with my kids. If i had any!   s:lol: :lol: s:lol:

Anyone fancy trying it??  s:D s:D

The mr2 has pre-tensioners?? Never knew this...how advanced.

I'd still like this too.
My youngest is now forward facing, but there's still something slightly unnerving about knowing her little face could be smashed in and hands/arms broken even if I were to have a crash that would result in less damage sans-bag.

Cheers for all the replies,  and yeah it did feel like a bit of a risky assumption to be making.

had a look through a DVD I've got that has some of the wiring diagrams for the '2 and I certainly couldnt see a connection to the passenger seat sensors and the SRS controller, there is one to the driver's seat strangely..   I wonder if that's to avoid airbags being deployed accidentally when in transit

ended up just disconnecting it after consulting the wiring diagram, and it's arguably easier to do that than it would be to unbolt the seat and get to the connector that's beneath it anyway!

Steps:

IMPORTANT:   first disconnect the battery and wait for at least 90 seconds - according to the info I found the SRS system has a backup power source which could trigger the airbag squibs even if the main battery is not connected.

- Once battery has been disconnected and you have waited 90seconds, remove the glove box
- Get on your back so that your head is down in passenger footwell looking up into the space above the glovebox - you should see this


- As you're looking up, you'll see the cylindrical airbag assembly, and over to the left a small yellow connector onto the side of the airbag


- Follow that yellow connector and its wires back and you'll find the connector plug that connects the passenger airbag to the wiring loom.
- Disconnect the connector plug by sliding the small catch back slightly whilst pulling apart


- Tuck the two loose ends away to ensure no risk of them accidentally touching
- Glovebox back in
- Reconnect battery
- Start engine and check that you have now got an airbag warning light on the instrument cluster

The airbag warning light will stay illuminated but I can handle that and see it as a useful reminder that I need to sort it out before I carry a normal adult passenger again!

Hope that helps those that are still looking for a solution to this
