How does an obd2 scanner work?

The scanner is connected to the diagnostic block, which is located at the base of the steering wheel. Usually it is a trapezoidal connector under the steering column or bottom of centre console. It has several data exchange protocols: CAN (ISO 15765-4), VPW, PWM, KWP2000 and ISO9141. The machines produced since 1996 are available for diagnosis. It was then that they began to produce cars with an obd2 connector.

This is a standard type of connector that transmits (pass) the maximum number of errors. It fits most machines, but some brands do not support this format, so read the car's passport before you buy it, which type of the connector is in the car.

Depending on the model, devices can work by ‘Plug and play’ principle like portable scanners or with APP for your smartphone like bluetooth/wi-fi models.

Data can be transferred not only through a standard usb cable, but some scanners can work via bluetooth or wi-fi. This is convenient, because the absence of wires is much more comfortable. Immediately after switching on, you will be able to see the main indicators:

  • Coolant is the current temperature of your engine
  • Vacuum - the state of the vacuum brakes,
  • Pressure - for brakes and cylinder
  • Speedometer and odometer - violations are detected here. Drivers can cleverly remove the mileage readings.

Depending on the installed application, you can select several diagnostic tests. Here it will identify more than a hundred faults and translate this code into your language. Here there is the possibility of resetting errors that occurred when changing auto parts or wiring, after which the car can normally drive.
