Join Our Team in San Bernardino, CA

Step into a typical day as a Fleet Diagnostics Technician supporting student transportation. You arrive at the San Bernardino maintenance facility, review driver notes, and jump straight into vehicle triage. Using scan tools and a multimeter, you pinpoint electrical faults, trace intermittent issues, and validate concerns with a preventative maintenance (PM) test drive. You move from braking and steering checks to evaluating suspensions, drive trains, and power steering units—then on to cooling, lubricating, clutches, transmissions, and oil/temperature/gas regulating components. When major work is complete, you arrange inspections and approvals before any vehicle rolls out. Throughout the day, you log time, parts, and services performed, assist Tech I’s with engine, transmission, and differential rebuilds as assigned by the manager, and handle occasional road calls. You finish by restoring a safe, organized work area and flagging any unsafe conditions or vehicle abuse to the Lead Technician.
