Monaro Airbag Fault

[V8Monaro]

Hi everyone,

Was driving the other day and the car just came up with airbag fault for no apparent reason. Monaro VXR 55 plate. Any ideas why this might happen and is there a fix?

loose wire under a set maybe.

without having the code read to see what airbig it was it thinks it has faults with its all just guessing games.

This is such a common fault with attendant discussion, perhaps the threads concerning this could be consolidated and could be put into FAQ's.

OP It is a latched fault which means that you need to fix whatever it is before you get it deleted with a Tech 2 - A Tech 2 is the GM device used to talk to the BCM (Body Control Module)

To my knowledge Walkinshaws are the only company to have one. Unfortunately the codes given don't seem to be definitive.

Monkfish must have dealt with a few of these along the way. ETA MF have a Tech 2 as well.

Your possible causes are - in not a particular order of likelyhood:

1. Air Bag failure.
2. Coil spring on steering wheel
3. Faulty connection of wiring/connection under seat.

(Anyone else can add to the list as necessary)

There was a warranty issue with these cars around 2005 and a factory recall which IIIRC was something to do with the seat.

The recall was to fit a spring to the seat and runner to provide a continuous earth and prevent a possible build up of potential in the airbag unit. This was only a theoretical problem, there were no known instances of unwarranted airbag deployment because of this.

Monkfish have a Tech2 imitation that can read / clear the codes.

If they don't stay cleared after resetting them, make a note of the codes, I've got the full service manual etc. so can either give you the information relevant to the codes, or just send you the whole manual to browse yourself

They include full instructions for testing / fixing them and what conditions cause the codes to be set.

If it turns out to be an airbag failure in either of the front seats, you're welcome to have mine, which are still at monkfish somewhere on a high shelf at the very back! If you do swap, and it's the driver's side seat, you'll want to use your electric adjustment controller, as mine was a bit broken (and is on my desk)

Thanks for the advice everyone and James for the offer of the replacements if needed. I will see if my work has a diagnostic that will read the codes then hopefully you guys can point me in the right direction.

Thanks a lot

Hopefully it does, fingers crossed

Only just had a chance to get this looked at, plugged it in at work whilst getting an MOT (which it failed because of this light!)

Came up with code 21, drivers side airbag resistance too high.

Can anyone advise the best things to check first, is it a seat replacement?? In which case, Sturdy HSV can I take you up on your kind offer?????

Had this on a couple of cars and both turned out to be loose wires/connectors , its also the cheapest thing to check and eliminate, though you should disconnect the battery first, and give it 15 minutes or so to eliminate any residual as you really don't want a bag going off when your head is in the locality . keep in mind just because something looks like its joined together well it doesn't always mean that it is.

and as posted about unplug and plug back in the airbag wires under the drivers seat..

Hi again

Cars been off the road for a while but just relaxed it and looking at tidying a few things up and making some improvements.

One of the things is going to be to fix this light, which is still coming up!

I have just had the steering wheel airbag off. Unplugged it all and plugged it back in. Then I unplugged everything I could under the drivers seat and plugged it back in.

What's the next step as it's still there surprise surprise!

Any help much appreciated.

You may have fixed it but the light won't go out until it's reset

[V8Monaro]

Ok Im hoping the diagnostic machine that read them code before can do this? Or do you need a specific machine? Last time it put the light off but it came on again as I drove away.

If it turned the light off before it will again

Try reading my post again

[V8Monaro]

Still haven't sorted this and it is MOT time soon!

I have tried to switch the light off and the same code has came up, I have a printout of the problem scanned below. The problem is the ohm level of the drivers airbag loop resistance, so the diagnostics cannot switch it off till this comes down.



Can anyone help me? What do I need to replace to sort this???????

[ARAF]

Looks like it's what they call the 'clock spring' under the steering wheel.

[V8Monaro]

Thanks is this shared with any other Vauxhall model or is it Monaro specific? Any idea of the best place to get one? Hopefully its not silly £££

[ARAF]

Specific I think. Monkfish have them, but at the price you may want to check that is the problem before buying.

Oh dear I was hoping it would be less then that. How would I go about checking what is at fault rather then risking £100
