Diesel Fleet Diagnostics Technician (School Transportation)

Imagine starting your day in a high-tech maintenance bay where school buses and medium/heavy-duty vehicles line up for care. You open your work tablet, review the preventive maintenance schedule, and head out for a short test drive to validate a driver-reported issue. Back inside, you trace an electrical fault to its source, swap in a component, re-run computerized diagnostics, and verify the repair with a post-service drive. By mid-day, you’ve logged time and parts, installed a telematics device, and responded to a road call—keeping students and communities moving safely.
