CAN/J1939 Diagnostics
Network topology, voltage and resistance checks, message interpretation, missing heartbeats, wiring faults, module isolation, and CAN-analysis tools.
HYB
Hybrid-Electric Diagnostics
Energy storage, inverters, traction machines, regenerative braking, cooling, controls, and structured fault isolation for hybrid transit buses.
DMM
Electrical Diagnostics
Voltage drop, loaded-circuit testing, grounds, reference circuits, sensors, relays, power distribution, schematics, and intermittent faults.
TA
Technical Assistance
Remote or on-site support for difficult fleet problems, fault-code review, data interpretation, test planning, technician coaching, and diagnostic strategy.
About JBC
Decades of transit maintenance experience behind every course and diagnostic recommendation.
JBC Technical Services is built around real-world fleet maintenance experience—from the technician level through executive fleet leadership, engineering, training, advanced propulsion, and battery-electric bus deployment.
Experience that connects the shop floor to fleet strategy
Joseph Cheney's career began as a transit bus technician and progressed through foreman, director-level maintenance and engineering leadership, and deputy director responsibilities. That experience shapes JBC's training philosophy: technicians learn best when instruction connects system theory to actual vehicle symptoms, schematics, measurements, data, and repair decisions.
His background includes large transit fleets, battery-electric and hybrid bus programs, high-voltage energy storage systems, traction inverters and motors, reliability-centered maintenance, technician workforce development, new-vehicle procurement and commissioning, maintenance facility projects, and the development of in-house component repair capabilities.
Transit Bus Technician
Built a hands-on foundation in preventive maintenance, brakes, steering, suspension, diesel engines, transmissions, HVAC, low- and high-voltage electrical systems, CAN networks, hybrid systems, and electric propulsion diagnostics.
Maintenance Supervision & Technology Evaluation
Directed maintenance activities, complex repairs, quality control, technician performance, training needs, safety activities, and testing/evaluation of new products and technologies.
Director of Maintenance, Training & Engineering
Led maintenance for a large multi-facility transit fleet, managed major operating and capital programs, directed technician training and engineering support, and participated in major bus, facility, CNG, dual-mode electric, and hydrogen projects.
Deputy Director of Maintenance
Oversees fleet maintenance programs, regulatory compliance, preventive maintenance, technician development, reliability improvement, hybrid component overhaul, high-voltage battery repair, and battery-electric bus deployment.

How we teach
Build diagnostic capability—not just parts replacement.
JBC training is designed around repeatable troubleshooting habits technicians can use after the class ends.
Learn the system
Understand architecture, operating states, energy flow, network relationships, permissions, interlocks, and failure modes before testing.
Collect evidence
Use schematics, DMM measurements, fault codes, live data, CAN information, voltage drop, current, and insulation/isolation information appropriately.
Isolate the root cause
Develop a logical test plan, distinguish primary from secondary faults, confirm the failure, verify the repair, and document the evidence.
Training outcomes
Designed for technicians, supervisors, and fleet organizations.
“Training is organized around the same schematics, measurements, software, and fault information technicians use in the shop.”
Practical & fleet-focused
“Courses can be adapted to the customer's vehicle configuration, technician experience, diagnostic tools, and operational needs.”
Customizable delivery
“The goal is to develop a repeatable diagnostic process so technicians can prove faults instead of replacing parts by guesswork.”
Root-cause centered
FAQ
Common questions
Can training be customized for our fleet?
Yes. Course content can be tailored around your vehicle platforms, propulsion systems, technician skill levels, diagnostic equipment, common failures, and operating environment.
Do you provide on-site training?
Yes. JBC can provide on-site instructor-led training using customer vehicles, components, schematics, service information, and shop equipment where appropriate.
Can JBC help with a difficult bus that will not start or go Ready?
Yes. Technical assistance can include fault-code review, system-state analysis, electrical and network test planning, CAN/J1939 data interpretation, and technician coaching.
Does course completion make a technician OEM-certified or high-voltage qualified?
JBC training can support an employer's qualification process, but course completion by itself does not grant OEM authorization or automatically establish employer-designated high-voltage qualification.
