The check engine light is one of the most common warnings drivers encounter on their vehicle’s dashboard. It can signal a range of issues, from minor glitches to more serious problems under the hood. Often, once the issue is addressed, the check engine light remains illuminated, which may leave you wondering how to reset it. Thankfully, tools like the ANCEL automotive diagnostic scanner provides an easy solution to reset the light, ensuring that you don’t have to visit a mechanic every time it pops up.
What is the OBD2 Scanner
The OBD2 scanner is a professional diagnostic tool that allows you to communicate with your vehicle’s onboard diagnostic system. This device is invaluable for checking trouble codes, diagnosing issues, and clearing diagnostic trouble codes (DTCs) that trigger the check engine light. The car diagnose scanner is designed to work with most cars manufactured after 1996.
1. Plug the ANCEL OBD2 Scanner into Your Vehicle’s OBD2 Port
The first step is to plug the automotive scanner into the OBD2 port of your vehicle. This port is usually located beneath the dashboard, near the steering column. Depending on your vehicle model, it might be slightly different, but it is typically easily accessible. Once plugged in, ensure that the scanner is securely connected.
2. Turn the Ignition to the “ON” Position
Without starting the engine, turn the key to the “ON” position. This action powers up the car’s electronic systems, including the OBD2 system. If your car is equipped with a push-button start, simply press the start button without pressing the brake pedal.
3. Power On the ANCEL OBD2 Scanner
Once your vehicle’s ignition is in the “ON” position, power on the diagnostic car computer scanner. Most models have a power button or automatically turn on when plugged in. If you’ve followed the previous steps correctly, the scanner’s screen should light up, displaying its main menu or interface.
4. Select the “Read Codes” Option
On the scanner’s screen, navigate to the option that reads “Read Codes” or something similar (this might vary slightly depending on the model). This step will allow the scanner to communicate with your vehicle’s ECU (Engine Control Unit) and retrieve any stored error codes that triggered the check engine light in the first place.
5. Review the Diagnostic Trouble Codes (DTCs)
After selecting the Read Codes function, the ANCEL OBD2 scanner will display any existing DTCs. These are alphanumeric codes that indicate specific issues with your vehicle. Even if you’re just resetting the light without addressing the issue, it’s a good idea to review these codes to ensure that the problem has been resolved.
6. Clear the Codes to Reset the Check Engine Light
Once you’ve reviewed the codes, navigate to the option that says “Clear Codes” or “Erase Codes”. This will reset the check engine light by clearing the stored trouble codes in your vehicle’s ECU. After completing this process, the check engine light should turn off.
7. Turn Off the Ignition and Disconnect the ANCEL OBD2 Scanner
Once the codes are cleared, it’s time to turn off the vehicle’s ignition and disconnect the ANCEL OBD2 scanner from the OBD2 port. You may want to start the vehicle again to confirm that the check engine light has been reset and that no new warnings appear.
What to Do If the Check Engine Light Comes Back On
Even after resetting the check engine light, it may come back on. This can indicate that the original issue hasn’t been fixed. If this happens, it’s advisable to re-scan your vehicle to retrieve any new or persistent codes. Ignoring recurring warning lights can lead to more serious mechanical issues down the line. In such cases, you might want to consult with a certified mechanic to address the underlying problem.
Conclusion
Resetting the check engine light with the engine code scanner is a straightforward process that saves time and money. By following the steps outlined in this guide, you can quickly clear any stored trouble codes and reset the check engine light yourself. However, always ensure that you resolve the underlying issue causing the light to appear in the first place to avoid any long-term damage to your vehicle.
