Hello! I have a 2007 Pontiac G6 base model, I’ve done a bunch of interior modifications including 2010 steering wheel buttons, and cluster swap, and adding an aftermarket radio with one of those turn signal speakers so I can hear the car ding at me and let me know when the turn signal is activated. Recently the anti theft light has been coming on while I’m driving. Not sure why this is happening, but I think it might be the BCM. Here’s a video of me restarting the car with the light still on and the car dinging. It normally lights up randomly when I’m driving down the road.
