Years ago, I disconnected the passenger side airbag on my 92 968 and installed a 3 ohm resistor to trick the system into thinking the airbag was still connected. Now, I've removed the airbag module (I'm converting the car to a mostly-track car), and I'd like to go ahead and remove the control unit as well. Does anyone know if removing the control unit altogether will trigger the airbag warning light? If so, is there a way to trick the system into thinking everything is still there, when in fact it has all been removed? Thanks.

 

I have my controller unplugged, the passenger airbag removed and the drivers disconnected with no warning light.

 

When you say your control unit is unplugged, do you mean on the input side, or in the output side (the side leading to the air bag module)? Did you do anything, like install a 3 ohm resistor, to prevent the light from going on? I'd always heard that if you just disconnect the connectors from the control unit to the air bag module, it will trigger the warning light, which needs a very expensive tool to reset. The 3 ohm resistor is to simulate the load of the air bag control module. I know of somebody who's interested in buying a control unit, and I told him I'd sell him mine, but only if I'm sure there's no risk of triggering the warning light upon removing it. I've never heard of anyone completely removing their control unit (other than racers who completely rebuilt their dashes). Thanks.

 

pull the light.

 

Easy way
disconnect the six pins connector,then install a jumper between pins #3 & #4 (female side of the connector)this will disable both airbags without the ligth comming on.Just make sure that the jumper is install in such a way that it can't pull out,otherwise the car is gone to stall.For easy access remove the glove boxe.I've been driving my 968 over a year with the jumper & no problems to date.

 

+1. Been running this way for years.

 

Thanks! This is exactly what I was looking for. I really appreciate the tip. I have to say, I haven't spent much time on this forum in the nearly six years I've owned my 968 (spent most of my time on the 968-specific forums), but I'm very impressed by the quantity and quality of responses I've gotten to my questions here, which is a testament to the level of knowledge on this forum. Plus, you guys obviously aren't afraid of getting your hands dirty working on these cars. I think I'm going to be spending a lot more time here - hopefully I can offer something in return for the help I've already gotten.

 

--------We also got a 968 specific forum here on RL.Personally I spend time on both here & there & love it.Could you send us pic of you 968 ps,we're pics addicted here.

 

Sure, a few pics is the least I can do after all the great help I've gotten here:

It's a 92 coupe, slate gray, 6-speed. It looks nice in pictures, but I'm afraid it's one of those "good from far, but far from good" cases - a nice car, but it had a lot of issues, mostly leaks from practically every seal (including the RMS), inoperable sunroof, clutch on its last legs (probably the DMF, too), hatch glass in the early stages of de-laminating, and it was erroneously diagnosed with having a cracked firewall, so rather than spend the time and money fixing everything (and the above is just a few of the issues), I've decided to convert it to a mostly-track car, as this is what's given me the most enjoyment from the car. I've got the engine out of the car for a complete rebuild, and will hopefully start re-assembling it this week.

 

I disconnected the round plug like the diagram above. Mine does not require the jumper, the car is not running a DME relay. You should not get a light.

 

Now that I'm convinced I can remove the air bag control unit without triggering a permanent warning light, I see that two of the nuts holding the unit in are very strange, serrated/sawtooth faced nuts. The picture below shows an edge-on view of the unit, with one of the weird nuts near the left side of the picture:

Any idea what type of socket I'd use to remove this thing? Thanks.

 

No socket, they aren't ever meant to be removed.

 

Yes, I can understand why, but I'm turning my car into a track car, so it will have a full harness, and I've already removed the actual air bag module, so the control unit is superfluous. I've found someone who needs an air bag control unit, so I'd like to remove it and sell it to him to help finance my project. Guess I'll have to either drill out the stud, or see if I can attack this thing with vice grips, or a cold chisel. Moddedeverything951S - is this what you ended up doing to remove yours? Thanks.

 

Ernie,

Finally got the control unit out. I see that it has three connectors, a pink, a white, and a blue one, and they all have six pins. Which ones do I jumper? All of them? Thanks.

Here's a picture of the unit:

[QUOTE=Cloud9...68;9210233]Ernie,

Really I can't tell you which is which since I kept it simple & didn't remove the control unit out,all I did is pull out the six pins connector coming from the control to the one comming from the car.I remember those two connectors being held by an orange plastic sheat that was a PITA to take out.In the pics you'll see both ,the one in the background was the male which I wrap securely & tie-wrap out of the way so there will be no chance of it shorting.The one in the forground (female) is the one with the jumper install also all wrap up & tie-down.Probably Darwin went the same way I did & I can't see removing the control boxe even on a race car how much weigth your gone to loss by doing so? or are you removing it for some other reason?.And remember the more electronics you'll remove from a 968 the better chance of having problems poping up somewhere else.
