Fixing airbag warning light after removing OnStar VCIM?

Recommended Posts

I'd like to remove the OnStar VCIM on my 08 GMC Sierra 1500 - not because I'm paranoid or anything, but because it's useless with the 2G cell card on it, it has no Bluetooth feature, and because I have installed a CarPlay receiver that does everything it did, plus more. I rather use the room under the center panel for a 4 channel mini-amp. However, when I disconnect the two wire connectors that go to it, my airbag light stays on. Looking at the service manual and electrical manual, I see the VCIM acts as a highspeed CAN pass-through. Has anyone removed their OnStar and just connected the HS-CAN wires from both connectors together to recreate the pass-through? If so, did it get rid of the airbag warning light on the dash? Thanks!
