To use an OBD-II scanner, plug the device into the OBD port located under your vehicle’s steering column, turn on the ignition, and follow the instructions on the screen. However, it’s important to note that an OBD-II scanner is a simplified version of a scan tool and can’t perform more complex functions.
Steps To Use An Obd Ii Scanner
Locate the OBD II port in your vehicle. It is usually located under the steering column, but it can vary depending on the make and model of your car. Refer to your car’s manual for specific instructions on where to find the port.
Once you have located the OBD II port, plug the scanner into the port. Ensure that the scanner is securely connected and properly inserted.
Turn on the ignition without starting the engine. This will power up the scanner and allow it to communicate with your vehicle’s onboard computer.
Once the scanner is powered on, it will start reading and displaying the diagnostic codes stored in your vehicle’s computer system. Take note of these codes as they will provide information about any issues or malfunctions in your car.
After obtaining the diagnostic codes, you will need to interpret them to understand the specific problem areas in your vehicle. Consult the scanner’s manual or an online resource to decipher the codes.
If you have successfully resolved the issues in your vehicle, you can clear the diagnostic codes using the scanner. This will reset the check engine light and ensure that the problem has been resolved.
