In this article, we will show you how to use scantool.net v1.13 to read and clear the trouble codes from your car's computer. We will use an example of a car that has a code P0171, which means that the fuel system is too lean.
Step 1: Connect your PC to your car's OBD-II port
First, you need to connect your PC to your car's OBD-II port using an OBD-II cable or adapter. Make sure your car's ignition is on, but the engine is not running. Then, launch scantool.net v1.13 and select the interface and the protocol that match your car's specifications. For our example, we will use an ELM327 interface and an ISO 9141-2 protocol. Click on \"Connect\" and wait for the software to establish communication with your car's computer.
Step 2: Read the trouble codes
Next, you need to read the trouble codes from your car's computer. Click on \"Trouble Codes\" and then on \"Read Codes\". The software will display the codes that are stored in your car's computer, along with their descriptions and status. For our example, we see that there is one code: P0171 - System Too Lean (Bank 1). This means that the air-fuel ratio in the engine's cylinder 1 is too high, which can cause poor performance, high emissions, or damage to the engine.
Step 3: Clear the trouble codes
After you have identified and fixed the problem that caused the code, you can clear the code from your car's computer. Click on \"Trouble Codes\" and then on \"Clear Codes\". The software will ask you to confirm that you want to clear the codes. Click on \"Yes\" and wait for the software to erase the codes from your car's computer. You can then verify that the codes are gone by clicking on \"Read Codes\" again.
Step 4: View live data
Finally, you can view live data from your car's sensors to check if everything is working properly. Click on \"Live Data\" and then on \"Select Items\". The software will show you a list of available data items that you can view. You can select or deselect the items that you want to see by clicking on them. For our example, we will select \"Short Term Fuel Trim (Bank 1)\" and \"Long Term Fuel Trim (Bank 1)\". These are the values that indicate how much the fuel system is adjusting the air-fuel ratio to keep it optimal.
Click on \"Start\" and wait for the software to display the live data in a graph or a table format. You can also change the display mode by clicking on \"Graph\" or \"Table\". For our example, we see that both short term and long term fuel trims are close to zero, which means that the fuel system is not making any significant adjustments to the air-fuel ratio. This indicates that the problem that caused the code P0171 has been fixed. 06063cd7f5
