B0899 is Device 1 voltage low
U1064 is lost communication w/body control module
P0171 is system too lean
I can not find out what the Device 1 is, and can it be because of loss of contact with the BCM?

Have you tried contacting a dealership in your area for more information? There are many benefits to taking a vehicle to your local dealership. You can guarantee that technicians are certified and that the parts come with a GM parts warranty. For these reasons, I would recommend taking the vehicle to your local dealership to be diagnosed. They should be able to assist you further and have a plan for addressing the issue. Please feel free to keep me updated regarding the fix. Thank you in advance.
Tricia, GM Customer Service.
