Current availability
The subject-specific curriculum is authored but not yet published for completion. Learners may inspect its scope and learning design now. Start, grading, and completion remain unavailable until every listed gate passes.
- qualified review approval is required
- reviewer identity, qualification, evidence, and approval date are required
What this course establishes
- Map employer, credential, regulatory, vehicle, task and test-drive authority without claiming technician qualification
- Analyze fictional diesel, air, electrical, network, brake and aftertreatment systems using supplied measurements and controlled fault trees
- Audit fictional preventive-maintenance, defect, repair, verification, regulatory handoff and quality records without touching a vehicle
Entry knowledge
- Careful reading, arithmetic, units, electrical and pressure fundamentals, mechanical reasoning and willingness to stop when vehicle identity or safety evidence is missing
- Ability to distinguish customer complaint, verified symptom, diagnostic trouble code, test result, root cause, repair instruction and acceptance criterion
- Commitment to emissions integrity, accurate records, accessible communication, contamination control and never bypassing safety systems
Scope boundaries
- All vehicles, faults, measurements, fluids, parts and records are fictional. Learners must not start, move, lift/support, enter, road-test, inspect under, disable, disassemble or repair a vehicle; service brakes, tires/rims, fuel, air/hydraulic/spring, electrical/high-voltage, aftertreatment or MVAC systems; isolate energy; weld; or handle refrigerant, batteries, DEF, fuel, exhaust or waste through this course.
- This is not hands-on trade training, employer authorization, CDL, brake-inspector qualification, state inspection license, manufacturer/dealer authorization, warranty approval, EPA Section 609 certification, refrigerant credential, industry certification, college credit or professional certification.
- Only current OEM service information, regulators, motor carrier, employer, qualified/certified technicians and authorized inspectors govern real work. No internal completion, time or score predicts safe technique, qualification, employment, regulatory compliance or repair outcome.
Fastest competency route
Completion is self-paced and competency-based. Prior knowledge may shorten conceptual study only when vehicle configuration, service-information revision, units, measurements, hypotheses, repair authority and verification remain traceable. Hands-on competence, certifications and regulatory qualifications require supervised external routes; no fastest-credential or employment promise is made.
- Pass diagnostics on authority, vehicle identity, systems, PM, fault isolation, emissions, safety and records
- Repair every planted defect in the fictional diesel-service audit
- Complete and defend the diesel diagnostic and maintenance dossier
Full self-paced route
- Pathway, vehicle identity, service information, work orders and preventive maintenance
- Diesel/aftertreatment, electrical/network, air/brake and supplied-data diagnostics
- Energy/lifting/tire/MVAC boundaries, repair verification, regulatory handoff and quality
- Applied diesel diagnostic and maintenance dossier
Lesson and assessment map
Technician pathway, vehicle identity, service information, work orders, and preventive maintenance
Build a fictional service file that keeps vehicle configuration, authority, complaint, inspection and maintenance evidence traceable.
4 questions: recall, application, judgment, and error correction.
Diesel combustion, aftertreatment, electrical/network, air/brake systems, and diagnostic reasoning
Use fictional supplied measurements to build and update fault trees without replacing parts or altering a vehicle.
4 questions: recall, application, judgment, and error correction.
Energy, lifting, tire and MVAC boundaries, repair verification, handoff, and quality
Audit fictional safety, repair and regulatory evidence while preserving defects, authorization and verification history.
4 questions: recall, application, judgment, and error correction.
Required applied assignment
Diesel diagnostic and maintenance dossier
Repair the fictional diesel-service audit and create one paper-only vehicle dossier from credential and vehicle identity through PM, supplied engine/aftertreatment/electrical/network/air-brake diagnostics, safety and regulatory gates, repair verification, handoff and quality. Do not start, move, lift, test-drive, inspect physically, service, disassemble or repair a real vehicle.
- Employer, certification, CDL/test-drive, brake-inspector, state-inspection, OEM and Section 609 authority matrix
- Vehicle/configuration and service-information register, complaint/verified-symptom record and PM plan
- Unit-checked supplied-data ledger and engine, aftertreatment, electrical/network and air-brake fault trees
- Energy/lift/tire/MVAC/emissions boundary audit plus defect/repair/verification chain
- Regulatory handoff and quality dashboard with duplicate repair, denominator, severity, missingness, accessibility and balancing measures
Passing standard: 80 of 100 points, with substantive revision required.
Continue after this course
- Verify employer, manufacturer, motor-carrier, state inspection, CDL/test-drive, brake, MVAC/refrigerant and certification requirements for the intended work
- Complete supervised hands-on training in inspection, measurements, lifting, maintenance, diagnostics, repairs and verification on the exact equipment
- Maintain current OEM service, recall/campaign, emissions, safety, refrigerant, waste, accessibility and documentation competence
