DIM0102C – Diesel Electrical and Electronics Technician is a 300-hour Postsecondary Adult Vocational (PSAV) course carrying zero credit hours; the clock hours are the real measure. It is an Occupational Completion Point within Florida's Diesel Systems Technician program.
The course covers the electrical and electronic systems of heavy-duty diesel equipment — and this is where modern diesel work has largely moved. A contemporary truck, bus, or piece of heavy equipment is a networked system with multiple electronic control modules governing fuel delivery, emissions, transmission, and vehicle systems. Diagnosing it requires reading schematics, using a multimeter and a scan tool competently, and reasoning from symptom to cause rather than replacing parts.
Content begins with fundamentals: electrical theory, Ohm's law, series and parallel circuits, and electronic components. From there it moves through general electrical systems diagnosis including wiring, connectors, and circuit protection; battery diagnosis and service; starting systems; charging systems; lighting systems; gauges, instrumentation, and warning devices; and computers and computerized fuel systems including sensors, actuators, and control modules.
Instruction is competency-based and heavily hands-on. Students work on live equipment and are assessed by demonstration, not by written examination alone. Multimeter and scan tool proficiency, wiring diagram interpretation, and systematic diagnostic method are the skills that determine employability.
The course is offered at approximately 17 Florida institutions, predominantly district technical colleges: Daytona State, Eastern Florida State's technical programs, First Coast Technical College, Hillsborough, Indian River State, Immokalee Technical College, Lorenzo Walker Technical College, Lively Technical College, Miami Lakes Educational Center, Manatee Technical College, North Florida Technical College, Orange Technical College, Pensacola State, Pinellas Technical College, Radford M. Locklin Technical College, Ridge Technical College, and Withlacoochee Technical College.
Florida demand is substantial and geographically distributed: freight and trucking along the I-4 and I-95 corridors, port operations in Jacksonville, Tampa, Miami, and Port Everglades, transit and school bus fleets in every county, construction and agricultural equipment, marine diesel along both coasts, and emergency generator service — a sector Florida's hurricane exposure keeps busy.
Florida's Diesel Systems Technician program (FLDOE program number I470605) is a PSAV certificate built as stacked Occupational Completion Points, each separately employable, so a student who exits partway still leaves with a credential. The DIM courses are 300-hour blocks organized by vehicle system:
Each component carries zero credit hours and is measured in clock hours. FLDOE requires an average grade of 80% to earn an occupational completion point or certificate of completion — a higher bar than most academic coursework.
Program completion is not certification. The industry credential is ASE Medium/Heavy Truck certification, a series of examinations taken independently; T6 Electrical/Electronic Systems corresponds most directly to this course. ASE certification requires documented work experience in addition to passing the examination, so students typically test after entering employment. Many employers pay for testing and offer pay differentials for certified technicians.
The course appears as DIM0102 and DIM0102C. Districts implement the Diesel Systems Technician framework with some variation in how OCPs are packaged, and older program versions used different numbering. Transcript evaluators should work from the actual course number and hour count rather than the title.
Entry is normally by progression through the program's earlier OCPs. Program admission typically requires a TABE basic skills assessment. Because the work involves shop hazards, programs require safety orientation and student-supplied PPE, and most require a valid driver license — a commercial driver license is often advantageous for employment though rarely required for admission.
This is clock-hour CTE and does not carry college credit or transfer as general education. Some Florida colleges award articulated credit toward an A.S. in Automotive or Engineering Technology for completion plus industry certification, under local agreements rather than statewide SCNS equivalency. Confirm with the receiving institution.
Diesel technicians supply their own hand tools, and a working set represents a significant investment that grows over a career. Programs typically specify a required starter set, and students should budget for it. Employers generally supply specialty and diagnostic equipment.
Worth telling prospective students plainly: modern diesel work rewards diagnostic reasoning more than mechanical strength. Emissions systems, electronic controls, and networked architectures mean the technician who can read a schematic, interpret live data, and isolate a fault is worth considerably more than one who can only replace components. This course is where that capability is built, which is why it is 300 hours.
