Imagine being in the middle of 1000 acres of corn with winter bearing down. Your $800,000 combine won’t move because the speed sensor on the (unneeded for now) 4wd axle is producing an intermittent signal. You have a new sensor but you need a company rep to reset with a proprietary test tool to get the computer to accept the new sensor. You can’t reach anyone at the company because it’s Thanksgiving and they’re all out drunk driving in Brokeback MachoBuddy queerquads pretending to hunt Bambi.
Kinda puts a different perspective on fixing your selfie camera, eh?
