Help w/Child seat - airbag deactivation system

Recommended Posts

I have occasional need to be able to pick up my grandson at day care in my 2003 Boxster S (986) and I need to disable the airbag so that its safe to put him in the car.

 

I know the Airbag Deactivation Bar is discontinued from Porsche. I have a lot of problems trying to find a used one, primarily that the seat (which has a buckle built into the front) buckles into the deactivation bar is going to be over 10 years old. But the deactivation bar requires that you have the non-standard buckle that comes with the Porsche seat to insert into the device to let the system know when to disable the airbag.

 

I have found a schematic for the switch contained in the unit. It's actually quite simple, just 4 resistors and a Double Pole Single Throw (DPST) switch (see attached).

 

1) I'm looking online to order the parts for this, but I want to ensure that I have built it correctly before I plug it in. Can someone with a Airbag Deactivation Bar do me a favor? I need the resistance (ohms) from the two wires that are part of this unit to make sure that I have done it correctly and don't do damage to my airbag system. I need resistance with and without the buckle inserted. 

 

2) Question on activation. I know I need to have this functionality enabled by a Porsche dealer or indie with a PST2. I'm concerned that they may not enable it if they see that I crafted a device that works the same as the Porsche unit, so I would like to take the car to them before I install my homemade device. Can they do that, or must the PST2 think that the Deactivation Bar is already installed?

 

Many thanks

Hi, I am in the UK, but there is a guy that already sells a unit he manufacturers that has a switch on it to fool the system and turn off the air bag. Might be a better option.

Yes,I am aware of him, but he seems to have dropped off the map, hence I am building my own. Less than $5 in parts BTW.

my other questions still stand

I thought of doing that myself as well, but the safety of my grand children got the best of me. Purchase a used one from a Porsche Re-distributor. Just my 2 cents!

I recognize that concern, but the device is simplicity in itself -- 4 resistors and a switch. With visual confirmation via the flashing airbag light that it's working. By this logic we would never do any work on our own cars.

 

Nevertheless. i would like it if someone with a factory unit could give me the resistance (ohms) with the buckle inserted and not inserted
