How does an OBD2 Scanner work?
There are numerous different types of sensors installed throughout the different parts of a car.
These include manifold pressure sensors, engine knock sensors, oxygen sensors and many others. Every one of the sensors is designed to generate a signal and send it to the Engine Control Unit or the computer of the car.
This information is then used by the ECU for adjusting different elements to the most optimum levels.
In case the information received by the ECU from a sensor is out of proportion, a Diagnostic Trouble Code DLC is saved and a signal is sent to the check engine light.
In case this light comes up and remains on, your car might be suffering from a minor issue.
It is somewhat safe to drive the car in this scenario until you find the time to get it properly checked. In case the light starts blinking, the ongoing issue is likely to require immediate attention. Otherwise the engine might sustain some serious damage.
So when you plug your OBD2 scanner into the car, it transmits signals to the ECU and retrieve the relevant information on what actually is going on in there. On the basis of the received information, it displays the DLC code on the screen.
High end models also provide a few details on the ongoing issue along with the proposed solution.
