Tried the search with no luck...

Has anybody ever rewired the driver's side air bag into the defeat switch that is on the console for the passanger bag?

I want to keep the bags for street driving, but really don't like the idea of the damn thing going off in my face on the trail when I'm only wearing my lap belt.

Thanks!

Why dont you try removing the fused behind the glove compartment, thats what I have to do on mine...:smokin:

just pull the fuse....ever read your owners manual?:rolleyes:

Make an appointment at the dealer... I am sure they will help you..

:flipoff2: :flipoff2: :flipoff2:

Why don't you just leave the airbag at home!:D :D :D :D

Theres a TSB describing that operation for every dodge made vehicle ;)

Remove the glove box, remove the fuses, no big deal. Replace them when you get back on pavement. :flipoff2:

:jeep: __(OIIIIIO)__rOkOn:usa:

Serious question.... Lets say you pull your fuse, go wheeling and smack into a tree pretty hard... hard enought to set off an airbag. When you get to pavement and put the fuse back, does the airbag go off because the sensor has been tripped??

Another question. Is defeating the airbags even necessary? How many TJ owners have had them go off at inopurtune off road times? I don't know of any.

that's something I've wondered as well, which is why I like the idea of a defeat switch...the DC engineers had to have addressed this issue when they designed the existing passenger side defeat switch...

I don't know of any either...but that doesn't make me any happier about having an explosive devise right in front of my face...

Yeah, if you're wheeling and do something stupid enough to cause it to go off, you'll probably be glad it did :D

The switch is not in the bumper, dont worry about that. Said switch is a mercury filled device that goes off when it registers the velocity of mercury exceeding given parameters i.e. when you're going really fast and all of a sudden come to a complete stop. Sorta like how long it took to go from point A to point B at any given moment. It is set to work in one plane, front to back if you will, hence airbags don't go off in side crashes. The above switch is located somewhere in the vehicle, but not on the bumper, where it wouldn't get an accurate reading. Also, IMHO, in TJs, the "bags" shut off while in 4Low.
So, if you're in 4Low, they're always off. If, and only if, you're in 4H or 2H, and reach a certain deceleration speed, onlly then will the "bags" deploy. And usually such deceleration are not attained on the trail, unless you're falling off a cliff and NEED that BAG.

In your opinion, the airbags shut off in 4lo?! Dude, keep on smokin'. And whatever you do, don't share it! That's some bad shiznit!

The 4wd switch that's built into the 231's case is a simple on/off switch that closes the ground side of a discrete circuit that runs from positive to the indicator lamp to the switch to ground. The switch is not connected in any way to the airbag control module (ACM) or even the powertrain control module (PCM).

Not with just a lap belt. Like he said.

I dont want my air bags going off w/just a lap belt either. I'll take my chances when I am only wearing my lap belt.

And I disagree with the no airbags in low range theory too.

Air bags will deploy unless disconnected upon impact of 30 mph or greater head-on.

Take your TJ put it in low range 5th gear with 3-08 gears and 35inch tires... Now see how fast your going. (I bet is faster than 30 mph)

Ok next example. Your in low range and fall off a cliff (this could happen at the smokies) You fall at a speed greater than 30 miles per hour. (also possiable) You hit a large tree head on.

BAGS will deploy! You better not just have a lap belt on.

Or if you do, Your air bags better not be working. Ie: the cuttof switch.

On mine, I removed the fuses: 5 point harness's. I hope they wont go off, but I havn't tested the air bags yet.

Remember: Happiness is never having to see your air bags.
If they do blow, its at least 500 bucks each to repack them.

:eek: :eek:

Occasionally.

I'll check wiring diagrams to see if the 4-low comment is true or not. I suspect not, and guess its speed/velocity change related.

On my wife's $runner, 4-low disables ABS, but it doesn't affect the airbags.

if you are checking wiring diagrams, could you see what the passenger airbag defeat switch is actually doing?...disconecting the sensor from the bag, disconecting the power from the bag, etc.?

Dan-H, no need to check buddy. A 98 TJ FSM is exactly where my info came from. Generally, I try not to speak out of my ass.

http://pages.prodigy.net/coolmank/pics/misc/4wd-switch.jpg

I can't help on the passenger side disconnect box issue since that feature was a late release in the 98 model year. I could have had that "thing" added to my TJ free of cost at the dealership, but I prefer having the coin tray there for my ... you guessed it ... coins! Oohhhh, Aahhhhhh.

Oh, and Mr. 664n668, you're really putting too much thought into this. The conscensus seems to be that few, if any, TJ owners have had their air bags pop when off road. And I can guarantee that there are many out there that have put their TJ's through more severe service than you will. Your time would be better spent figuring out where best to place those neon chassis lights so that they don't get busted when you drive over a small rock.

CMK - thanks for the diagram.

664n668 - are you keeping the currie AR up front with the coilover? if not I'll make you an offer on it, I need one :)

So, your new to the sport of Flaming on the BBS? :flipoff2:

Nice TJ... Very Nice... I like it. So why did you keep it a secrete?

:bounce2: :bounce:

What brand Coilovers you got there? ARe you doing the work? or paying someone?

GET IT!!!

All that work and you can't figure out how to keep the jeeps ballons from inflating.

Alright, alright, so I jumped to "newbie-esque" conclusions because I was not well informed. I must say, you should have thrown some of them pics in early on. You could have avoided all the newbie crap as well as the JU stuff.

Nice work by the way. What are using for a monoball at the top of your triangulated 3 link rear susp.?

cmk

One other thing, and I am no expert so don't take this as gawd's word, but your rear suspension looks a little unorthodox ... to me. You're essentially running triangulated lowers and uppers. Is this something you've done before/seen before or something new?

Personally, I would be concerned about rear steer, even with tight tolerance pivots.

Please enlighten me if you know otherwise as I'm curious.

those are 17" Bilstein 9100s with HyperCoils...wish I could take the credit for the work, but that belongs to S&N Fab

thanks!...it's actually S&N Fab's work (I'm sure you've seen Lance's rig)...and the upper 'monoball' is a big-ass heim...1" if I remember right...:smokin:

Jason Conover (SNORTclown of S&N Fab) came up with the design...it's based on his past experience as well as a ton of research...

since this is still going to be my daily driver, and needs to remain street legal, I wouldn't let him do things like replace my gas tank with a fuel cell in the bed...or chop off the back 1/2 of the frame and all the sheetmetal...so he had quite a few constraints to work with...:D

we'll see this weekend how it works on the road and on the trail...:D :D :D

Should work fine. Triangulated uppers and lowers are nothing new under the sun ;) so far everyone I've heard from thats running them reports what I expected. no rear steer.

I have heard that even if you pull both fuses the bag will still go off because it has a power back up or something like that. Anyone confirm or deny(sp) this?

Phil:usa:

TJpwr, the "backup" you probably heard of is a capacitor in the ACM. It holds a charge large enough to fire the bags for approximately one second beyond the time that the battery is disconnected from the electrical system. The cap is there in case an accident causes the battery to "fall out" before the need to fire the bags arises.

FYI, common protocol in working on the bags (removal, etc) is to disco the battery, then hop real slow back to the other side of the Jeep on one foot with your entire right fist in your mouth and your left hand down the rfont of your pants, a 'la Al Bundy.

Once on the other side of the Jeep, stick your fingers in your ears and show 'em yer nutz.

I probably should start another thread for this since it isn't exactly on the topic of air bags ... but back to those triangulated lowers:

I can see now how that setup would not induce rear steer since the LCA frame mounts do not, in effect, meet at a monoball. But can someone enlighten me as to the advantage of triangulating the lowers rather than just running them in line with the frame? I'm asking because I just drew up a triangulated 3 link rear end, but now I'm wondering if I should rethink things before I start cutting metal.

go ahead and start a new thread (since we ain't talking airbags no mo) and I'll get Jason to come elaborate on his choice of design...

Start a new thread.. but its been covered before ;) make a model... if you keep the links parallel with the frame it WILL have some pretty severe rear steer.

Ah, time for a little "soul searchin' ".

I guess I'll have to model it up some more. At first thought, it made sense to me to keep the lowers from creating a pivot point in the horizontal plane hence the reason I thought parallel lowers would alleviate rear steer.

Rollover (http://www.midwestjeepthing.com/member/video/macsroll.mpeg)

My airbags didnt go off in my 95 XJ during this moment in April of 2001.

mac 'in love with the gas pedal' gyvr

664n668,

Yeah that's a nice ride...or it should be....BUT I still disgree with pulling the pull on the party ballons. My logic:
1. Ya need to be going over 30mph - Are you going to be doing that with a lap belt?
2. Regardless of the belt I'd rather an airbag than a steering wheel in the face, if it came to the crunch (literally).
3. So if it goes off it costs $500....Cost of cosmetic surgey to pull the steering wheel from your face....Frikken HEAPS

The TJ's airbags will supposedly only go off if the impact is sever enough to bend the frame.

How the heck did I get brought into this? :p
