Have this warning come up on SiD. Started as a intermittent fault but now on all the time. Plugged in to Tech2, and the passenger seat belt is registering as being clicked in when its not. Multi plug under seat checked and all wires appear fine. Any ideas would be helpful.
Welcome! :)
The passenger seat has a passenger presence sensor. Has that come detached, or broken? It might cause a fault, but Tech 2 suggests that the seatbelt is at fault. The seatbelt emergency tensioner in the 9-3 SS is in the door pillar, though.
Might be a case of trial and error, but try checking the cabling under the seat. The ignition needs to be off if you play with the airbag circuits.
I've had a look at the airbag circuit. The passenger presence sensor is connected to the Body Control Module, part of the fusebox. The seat belt latch is connected to the airbag control module, so if that switch is broken, I suspect that it will trigger the light because the airbag control module will sense a discrepancy between the seat belt being fastened and no one being sensed in the seat.
I can't tell if the belt latch switch is open or closed when the buckle is in place, but if it's opened by the buckle, you would get the same result on Tech2 if a wire in the loom was broken. The seat buckle switch wires one is blue and the other is green. If your car is a convertible the two wires are yellow and white.
Wires run to the airbag control module under the centre console under the cubby.
Thanks for the reply. All wiring checked and fine so everything is pointing to shot control module. So need to find a replacement >:(l
Unless things have changed the only option for an airbag control module is a brand new one, they can only be programmed once and there was no way to reprogram them, you could get crash data removed but could only refit the module in the same car it came from.
I was googling for the names of those airbag specialists whom HonestJohn in the DT recommends for these sorts of (very common) problems and came across someone (albeit in a BMW) with a similar cause, ie the passenger seat sensor:

Not sure if you're close to any of those mobile guys.
The guy I have looking at it was a Saab Tech for 15 years. He seems confident that a second hand unit is fine as long as the part code matches. At £40 its worth a go. Although I will post results just to clarify.

It won't be possible to add the unit with Tech-2 if it's second hand, I've tried this before and it won't work. Unless a service now exists to reset the units so they can be reprogrammed or change the programming...
Second hand unit arrived today. Fitted to car and airbag light on dash has gone out, and system all working fine. Result. It seems that if the replacement needs to be from a vehicle of the same year and model. If not then it can be reprogramed using the Saab TIS software.

Can I just check what year/model your car is? Given that Saab say it's not possible and I've got personal experience of what happens with second-hand units and with using TIS with Tech-2 I'd like to know what the workaround actually is!
2003 9-3 Vector. 2.2 TiD
Hi I have a 2003 1.8t saab 9-3, my airbag light came on when my wife sat on the. Plugged it in with snap on machine and got passenger seatbelt high low resistance, checked live data and It showed passenger front pretensioner 0 as all other pretensioners read 4 (I presume this is ohms). Anyway got a second hand pretensioner..no joy..same thing. Checked continuity between tensioner and module (all good). Read about modules being faulty so got a 2nd hand module (same part number but from a 2.2tdi) sent them both away to get repaired and coded...now neither will show fault codes with snap on machine??? And the f#$kin light is still on?!? Any help guys?? Thanks. Chris
I'm not 100% sure on this, but I don't think that the light goes off if you repair the fault. I think that it needs to be reset using a Saab "Tech2" diagnostic computer.
But wait for a reply from someone who knows for sure.
Oo and it flashed up srs module not programmed (thats what made me send the unit away for repair....ended up gettin another module and getting it coded. Absoultely doing my head in, im a mechanic by trade and pretty switched on with electrics and diagnostics but I am genuinely stuck!? Cant get my hands on tech 2 software, even phoned vauxhall several times...still waiting on a call back. Tech 2 software would be handy because my egt (exhaust temp sensor) light is on and saab were originally updating the ecu to remove the sensor under recall....(good luck with that now).
I had the passenger seat out and checked the presence sensor first when the light came on as I heard they were troublesome but im afraid the snap on machine has led me in the wrong direction. Never checked the anchor, will check it later.
There isn't any software that mimics the Saab diagnostic computer. You need the item itself, along with the Saab card. The hardware is the same as used by Vauxhall, but the slot in cards vary between the manufacturers.
The is a newer system that is used via a laptop and an interface, but it uses an internet link with a subscription
Whereabouts are you? Someone may be able to help point you to one in private hands or a local Saab specialist.
Dromore, county down, northern Ireland. I phoned vauxhall garage a few times to get the tech 2 diagnostics but kept getting told theyd phone back. The srs module will not communicate with diagnostics, the module musnt be coded correctly after getting repaired.
I don't know the Irish scene at all. There are two people who might help. Both post on www.uksaabs.co.uk Many of us are members both here and there.
The first is Jim, who posts as "Irish Carlsson". He runs a Saab repair place about an hour south of you at Kentstown, near Slane. I don't have any contact details other than on the other forum, and you need 5 posts to before you can send a private message.
The other is "BillJ". He lives in Devon now, but his father runs a Saab 9000 and lives in the Belfast area. Bill often goes over to help him out and knows of one or two places that might help. He also runs "Saabits" a Saab spares business, in his spare time.
Might be worth joining the other forum as well and seeing if either can help.
I'm not convinced that these services that remove crash data always do a great job, I've known modules get sent away and come back and Tech-II couldn't read the status of them properly but the airbag light did go out. Personally I wouldn't want to be driving a car like that!
Do you need to code in a 2nd hand module even if it hasnt been in an accident and its been taken from the same age/model of vehicle? Im attempting to get a 3rd module from the same year, engine, colour, model car to see if that does anything, cause I at least need a computer to talk to it to sort out problem.

My experience using tech-2 was that once a module was programmed it would not be possible to reprogram it and we couldn't reprogram modules with crash data removed. This meant second hand modules were never a possibility and we refused to do them after wasting time on it, then someone posted on this thread earlier saying it worked for them so I'm not sure if there is a workaround (which there is for things like deprogramming cd-changers) or if this information was inaccurate.
Yea it was that same comment on the module (plug and play) thats got me confused. Unfortunately I cant get my hands on tech2 so had to settle for snap on machine (going through vectra c). But now im stuck with 2 srs modules that will no longer communicate and the fella sorting it for me thinks im gonna have to go to saab to get a new module coded.... (F#*k that). Im not completely convinced it was the module at fault in the first place but I now need one just to get a diagnostic machine to talk to it. And it turns out my module is rare?! Real hard to get, the one I had lined up is different....so back to square 1. Incase anyone knows of one my module number 12800389.

That number also lists as 12798517 which is for the second half of 2003, that module should work if there is some way of doing it. Like I say we tried this a few times with Tech-2 and getting crash data removed and it never worked and we always ended up having to get a brand new module.
