Yes, I recently replaced the body control module BCM in my truck listed above 1500, now when I turn the truck to the on position weird buzzing noises come from instrument panel fuse boxes by brake pedal and under the hood.
I also had a diagnostic scanner hooked up to it when it was happening, and it made it back out turn off and on and restart.
