This is a real-world troubleshooting clip from a new T5.120 owner dealing with a faulty right-side brake light switch that was also blocking four-wheel drive from disengaging. The owner pulls the dash panel, uses the tractor's diagnostic menu to test each brake pedal switch, and physically isolates the bad connection by wiggling the switch. Short and narrow in scope, but useful for owners wanting to see the diagnostic menu in action and a specific early warranty issue.
