Passenger Presence Sensor Bypass?

I can't tell you how to bypass safety devices on your car but I can give you the wiring diagrams so you can see how the system works so you can go from there. Check out the images (below).

Thanks for the diagram, as I suspected the PPS appears to be on the CAN/LAN (LO SPD GMLAN) as labeled in your diagram, so there's no bypassing a contact or other simple permissive. Are there any diagrams showing additional connection to the PPS? Somewhere, somehow this connects into a capacitance-based sensor that's incorporated into the seat, unless "said" sensing is built directly into the module? Appreciative of any other insights or direction.

Yes, the sensor is built into the module, here are the rest of the airbag wiring diagrams so you can see how the system works. Check out the images (Below). Please let us know what happens.

Ken,

You say, "here are the rest of the diagrams", but no image/attachments that surface.

Thanks again in advance.

My bad, I updated the post.

Thank you, Ken,

The diagrams are glorious, and should I need any point-to-point troubleshooting I am indeed ready with your diagrams.

Since the only means to spoof the Sensing and Diagnostic Module is to provide it with the proper CAN codes from the passenger-side PPS module, do you by chance have access to the specific CAN message frames that it requires?

I'm an embedded developer and it wouldn't take a lot to create a CAN-based node on this LAN. If you have these codes, I'd appreciate you providing them.

As an aside, I've sent multiple messages to the Airbag360 group (in Ireland) to no avail as I was hoping they could shed some light on the sensor hack. They have a module for the prior Volt model, so if the codes haven't changed across models, this could ultimately be a win... here's the link:

I am sorry we don't have the codes you are asking for, but it sounds like you are on the right track. Use 2CarPros anytime, we are here to help. Please tell a friend.
