By following the steps above, you should be able to connect the OBD-II scanner to your car and reset the car computer. However, if you encounter any issues during the process, it’s best to consult a professional mechanic for assistance.
Step 3: Turn on the Ignition and Follow the Scanner’s Instructions
After connecting the OBD-II scanner to the port, it’s time to turn on the ignition and follow the scanner’s instructions. Before starting, make sure that all accessories in the car are turned off, including the air conditioning system, the radio, and the headlights.
Once you’re ready, insert the key into the ignition and turn it to the “on” position without starting the engine. This will activate the car’s electrical system and enable the scanner to communicate with the vehicle’s computer.
Follow the Scanner’s Instructions
After turning on the ignition, the scanner will start communicating with the vehicle’s computer. The scanner will provide instructions on the screen, and you should follow them carefully. The instructions will usually involve selecting the make and model of the vehicle and the type of diagnostic test you want to run.
If you’re unsure about which test to run or what the scanner is telling you, refer to the scanner’s user manual for guidance. You can also search online for information about your car’s diagnostic codes and what they mean.
Interpreting the Results
Once the scanner has completed the diagnostic test, it will provide you with a report of the results. The report will include a list of diagnostic codes and a brief description of each code.
- DTC Codes: Diagnostic Trouble Codes (DTC) are the codes that the scanner detects and reports. They indicate the problems that are currently affecting your car’s performance.
- Clearing Codes: After you have read the codes, the scanner will give you the option to clear them. Clearing the codes erases the diagnostic data from the car’s computer memory, allowing you to start fresh with a clean slate.
- Fixing the Problem: Once you have identified the codes and the problems they indicate, you can take the necessary steps to fix the issues. In some cases, the problems may be minor and easily fixed, while in other cases, you may need the help of a mechanic.
Remember that the OBD-II scanner is a valuable tool that can help you identify and fix problems with your car. However, it’s important to use it correctly and interpret the results accurately to get the best results.
Step 4: Disconnect the Scanner and Turn off the Ignition

- Step 3: Turn off the scanner.
- Step 4: Disconnect the scanner from the vehicle.
Disconnecting the scanner is just as important as connecting it properly. Failing to disconnect the scanner can lead to drained batteries and even damage to your vehicle’s onboard computer system.
Why Should You Disconnect the Scanner?
Reason 1: Leaving the scanner connected can drain your car’s battery. Many scanners draw power even when they are not in use.
Reason 2: If you leave the scanner connected and start the car, it may interfere with the vehicle’s onboard computer system. This can cause serious problems and even damage your vehicle.
Tips for Disconnecting the Scanner
- Tip 1: Always turn off the ignition before unplugging the scanner.
- Tip 2: Never yank the scanner out of the OBD-II port. Gently pull it out to avoid damaging the port or the scanner.
- Tip 3: Store the scanner in a safe place after use to prevent damage or loss.
By following these steps, you can safely disconnect the scanner and turn off the ignition, ensuring that your vehicle’s onboard computer system is not damaged and your battery is not drained.
