01
Start Here — Apprentice foundations
Foundations, Electrical & Testing, Drivability & Diagnostics, Brakes 1, and Steering & Suspension 1 give newer technicians a clean first lane built around inspection, basics, and repeatable test habits.
Curriculum
Diagnostic Core curriculum path
Build stronger proof, better complaint framing, and more confident system separation across the problems shops see every week. Best for technicians moving from basic competence into reliable diagnostic ownership. This path is meant to be assigned intentionally, not treated like casual shelf browsing.
02
Diagnostic Core
Foundations 2, Electrical 2, HVAC 1, Engine Performance 1, Transmission / Driveline 1, Engine Mechanical 1, and ADAS / Calibration 1 build stronger complaint framing, proof discipline, and system separation.
03
Systems Specialist
Brakes 2, HVAC 2, Engine Performance 2, Advanced Electrical / Network, Advanced Drivability / Scope Strategy, Network Diagnostics 2, Scope Strategy 2, ADAS / Calibration 2, Hybrid / EV, and Diesel courses deepen real specialty capability instead of pretending advanced work is leadership by itself.
04
Lead Tech / Leadership
Shop Workflow / Leadership, Comeback Prevention, QC / Final Check, Handoff & Escalation 2, and Diagnostic Leadership 2 turn strong technicians into better case owners, escalators, coaches, and shop stabilizers.

Foundations 2 for Dependable Technicians Under Pressure
Diagnostic Core · Recommended order #1
Technicians who already understand basic workflow and now need better judgment under pressure.
- 4 weeks · 8 lessons
- Build technicians who protect paid time, preserve diagnostic value, and communicate proof clearly when cases stop being easy.
Electrical 2 for Intermittents, Control Strategy, and Higher-Confidence Proof
Diagnostic Core · Recommended order #2
Technicians who already understand basic circuit testing and now need stronger proof strategy on harder electrical cases.
- 5 weeks · 8 lessons
- Build technicians who can narrow difficult electrical problems faster, prove the lane cleanly, and stop turning intermittent clues into random part replacement.
HVAC 1 for Honest A/C Diagnosis, Airflow Complaints, and Defensible Repair Logic
Diagnostic Core · Recommended order #3
Technicians who need stronger A/C complaint framing, better airflow-vs-refrigeration separation, and more credible HVAC recommendations.
- 5 weeks · 8 lessons
- Build technicians who can take vague hot-or-warm air complaints, test the right lane, and explain HVAC repair logic clearly without replacing parts on hope.
Engine Performance 1 for Complaint Framing, Fuel-Air Thinking, and Higher-Confidence Proof
Diagnostic Core · Recommended order #4
Technicians who need stronger complaint framing, better lane selection, and more disciplined engine-performance diagnosis under real shop pressure.
- 5 weeks · 8 lessons
- Build technicians who can frame engine performance complaints cleanly, test the right lane, and explain fuel-air-spark-control repair logic with stronger proof.
Transmission / Driveline 1 for Complaint Framing, Honest Testing, and Defensible Repair Calls
Diagnostic Core · Recommended order #5
Technicians who need stronger transmission complaint framing, better separation of driveline vs transmission symptoms, and more disciplined recommendation logic.
- 5 weeks · 8 lessons
- Build technicians who can frame transmission and driveline complaints clearly, test the right lane, and explain repair logic without turning every symptom into a full unit replacement story.
Engine Mechanical 1 for Compression Thinking, Timing Truth, and Defensible Mechanical Calls
Diagnostic Core · Recommended order #6
Technicians who need stronger engine-mechanical diagnostic discipline before recommending teardown, timing work, engine replacement, or other heavy repairs.
- 6 weeks · 8 lessons
- Build technicians who can frame mechanical-engine complaints clearly, test the right lane, and explain compression, timing, sealing, and restriction concerns without bluffing or overcalling the failure.
ADAS / Sensor Calibration 1 for Prerequisites, Responsibility, and Defensible Calibration Decisions
Diagnostic Core · Recommended order #7
Technicians and shop leads who need stronger ADAS calibration judgment, safer repair planning, and cleaner customer-facing explanations.
- 6 weeks · 8 lessons
- Build technicians who can identify ADAS-related repair triggers, confirm prerequisites, perform or route calibration responsibly, and document the logic without bluffing or shortcut language.
