Module 02Romanian
Modern vehicle architecture
Systems, wiring, and control dependencies
Trace a fault through control units, power supplies, grounds, 5 V references, gateways, and the relationship between command and result.
25 slides8 hours
Module 03Romanian
OBD and the diagnostic tester
Scanning, DTC evidence, and active tests
Scan completely, preserve freeze-frame and readiness evidence, interpret DTC status, and choose the tester function that answers the question.
25 slides8 hours
Module 04Romanian
Live data interpretation
PIDs, correlations, and plausibility
Select useful PIDs, check plausibility at known conditions, and compare requested versus actual values without mistaking calculated data for a measurement.
25 slides8 hours
Module 05Romanian
Sensors and actuators
Inputs, outputs, and circuit proof
Separate a failed component from a supply, wiring, connector, control, or mechanical fault by testing the whole circuit.

Module 06Romanian
Petrol engine diagnostics
Starting, misfire, and mixture faults
Work through no-start, misfire, and mixture symptoms by testing air, fuel, ignition, compression, timing, and control together.
25 slides8 hours
Module 07Romanian
Diesel Common Rail
Rail pressure, injection, and air path
Diagnose hard starting and loss of power by correlating air handling, rail pressure, injection control, and the mechanical system.

Module 08Romanian
Emissions and after-treatment
DPF, EGR, SCR, and AdBlue
Approach DPF, EGR, SCR, and AdBlue faults with evidence before attempting regeneration or replacing an expensive component.

25 slides8 hours
Module 10Romanian
CAN, LIN, and CAN FD
Network diagnosis and physical layer tests
Localize communication faults using network topology, module power and ground checks, termination, and physical measurements.

Module 11Romanian
Vehicle non-engine systems
Brakes, steering, SRS, body, and HVAC
Apply the same diagnostic method to braking, steering, body systems, SRS, HVAC, and other vehicle systems with appropriate safety limits.
25 slides8 hours
Module 12Romanian
Advanced diagnosis and practical exam
Unknown faults and complete case reports
Solve an unknown fault from symptom to verified repair, including incomplete data, intermittent faults, no-communication, and software decisions.

Study notes
Use the decks as a training companion, not a substitute for vehicle-specific service data.
The presentations teach a diagnostic method and safe test order. Pinouts, limits, repair procedures, and software decisions still need to be checked against the exact vehicle and current manufacturer information. Stop any test that could create a safety risk and use qualified local help for brakes, steering, SRS, high-voltage systems, fuel leaks, or a vehicle that is unsafe to operate.
