I have an '02-GU fitted with a TJM B/bar & just getting ready to fit the elec winch. Have studied a few instruction books and the specs for the winch and all seems OK but I'm after a second opinion re the SRS air bags.

The main control box is located under the dash, correct? Are there any sensors or anything at the front end where the winch cradle will sit between the chassis rails that can deploy the bags if knocked ??

I have often wondered what the action is the sets them off, like how hard does the front end have to be smacked before they deploy.

However my main question is, as I said, are there any sensors around the bullbar area to worry about.

Thanks all



I sometimes question my sanity . . . . and then it answers back.

Hey Salty,
I think the airbags are only activated when the vehicle is doing 25km/h or more so I think you are OK.

The main thing is to have an Airbag compliant Bullbar or you my compromise the working of the airbags.

Most sensors I believe are in the outer corners at the front.

No

I think you will find the airbag sensor is inside the vehicle cabin mounted on the transmission tunnel area

Just to add also the front airbag sensor normally looks at rapid decelleration speed as opposed to a impact on the front of the vehicle

I reckon an impact to the front of the vehicle would look the same as a rapid decelaration to an accelerometre ( thats the sensor in your srs system )

Would be a bit silly if you hit a wall at 110KM/h and the airbags deploy , then if you are stationary and get hit head on by something doing 110km/h and you get no airbag protection,

Also have an 01' GU with factory bar and winch , no worries , all the sensors are in the SRS module on the trans tunnel under the air con ducts .

Have a good one.

I was referring to the impact of fitting a winch (possibly hitting something with a hammer to line it up not being hit by something doing 110 kph)

On being hit by something head on i worked with a salesman at a truck dealership yeaars ago & he told a story (dont know if it is true as he was a salesman) about him & two mates who were travelling in the territory at night & pulled up at the 3 ways roadhouse

One bloke was fast asleep in the back seat of the car & didn't realise they had stopped so they parked the car head on to a road train

They than got out of the car went into the roadhouse & got everyone outside for a look & had the truckie turn all the lights on & hit the air horns

This bloke woke up to the sight of a bullbar filling the windscreen & thought he was about to die in a head on with a roadtrain & meanwhile everyone outside was cacking themselves

A mean thing to do to someone (hope he didn't have a heart condition) but funny nevertheless

But you didnt write that :

" Just to add also the front airbag sensor normally looks at rapid decelleration speed as opposed to a impact on the front of the vehicle "

Fair enough Glen you are correct i did write that but the original question was not "will the airbags deploy if i get hit head on by something doing 110 kph while i am stationary"

No but you said they only deploy from decelleating not imact from the front which is rubbish .

The usual instructiions with airbags is to completely disconnect all power and then wait 20 minutes before doing anything to do with airbags.

AFAIK most bullbars mount behind the airbag sensors and have crash cans to duplicate the original bumper bar crash can.

So as long as you are careful and disconnect all power then you should be Ok even if you were to short an airbag sensor wire.

Air bag wiring is sheafed in yellow conduit & sensors are Yellow (on Toyota's anyway but i think it is industry standard) to identify it & to stop people probing the wiring or trying to connect spotties to it

If it is yellow be careful what you do with it
