This course focuses on using an OBD2 scanner to evaluate a used car before buying.
It is not a general inspection guide – this training is specifically about diagnostics, meaning what you can detect using data from the vehicle’s control units.
This content is for members only.
What this course is about
This course teaches how to use an OBD2 scanner to uncover hidden issues in a used vehicle.
Instead of focusing on visual inspection, the goal is to understand what the car is telling you through its electronic systems.
You will see how diagnostics can reveal problems that are not visible during a normal inspection.
What you will see inside
- How diagnostic data reflects the real condition of the vehicle
- What information is stored inside control modules
- How faults, live data, and system status can indicate problems
- How different levels of scanners change what you can access
- Real examples of diagnostic checks on used vehicles
Basic vs advanced diagnostics
The course also shows the difference between basic and advanced diagnostic tools when checking a used car trough OBD2 scanner’s screen.
Simple tools can access engine data and basic fault codes.
Advanced scanners allow:
- Full system access
- Reading data from multiple control modules
- Deeper insight into vehicle condition
- More reliable evaluation of the car
This difference is critical when deciding how thoroughly you can check a vehicle.
Why diagnostics matters when buying a car
Modern vehicles store a large amount of information across different control units.
This data can reveal:
- Hidden or recent faults
- System status and readiness
- Information not visible on the dashboard
Diagnostics gives you a completely different perspective compared to a standard inspection.
Who this course is for
This course is designed for:
- Beginners learning car diagnostics
- People buying used cars
- Anyone who wants to understand what an OBD2 scanner can reveal
It is also useful if you want to use diagnostics as part of a more advanced inspection process.
What you need
To follow this course, you only need:
- A basic OBD2 scanner or adapter to start
- Full-system OBD2 scanner to put in practice everything learned
Some parts of the training also demonstrate what is possible with more advanced tools.
Focus of this training
This course focuses only on diagnostic checks using an OBD2 scanner.
It does not cover:
- Body inspection
- Paint measurement
- Mechanical inspection
The goal is to understand what can be verified through vehicle data.
