False warnings


Recommended Posts

Posted

2018 Silverado 1500 with 46000mi. (75000km) just received an OnStar report of  Theft Alarm just sitting in my driveway. Checked the vehicle out and open hood warning light came up when starting. Also seems the remote start is no longer functioning.

I'm assuming this is not good and doubt its still  under warranty. Anyone have a idea? Heard of similar before?

 

Thanks for any assistance

Sounds like the hood latch/ switch. Iirc a member did some research and found it has a resistance and the bcm or pcm reads that.
