I was able to run a diagnostic test on all the BCM modules and a few codes came back. After doing some research I found this indicates a problem with the vehicle's electronic control unit (ECU) software calibration, meaning the system has detected that the ECU software is not properly programmed or needs an update. I’m going to reach out to a few Chevrolet dealership and shops to see if they can reprogram or update the amplifier software hoping this will fix the issues!
