How to Use an Ancel OBD2 Scanner

    What Is A Bidirectional Scan Tool

    Ancel car obd2 scanners have a solid reputation for being exceptionally user-friendly. However, someone who has never used a bidirectional obd2 scanner device may be hesitant to try it for the first time.

    If you find yourself in this situation, there is no need to worry. Ancel OBD2 scanners are incredibly easy to use, and it will only take a few minutes to familiarize yourself with them. Here is a comprehensive guide on how to use an Ancel OBD2 scanner.

    Understanding the Structure of an Ancel Scanner

    Ancel's primary range of engine code readers and OBD scanners consists of handheld devices with a straightforward design. These devices feature an LCD screen that displays menus, images, and graphs, along with a few buttons.

    All Ancel scanners have essential buttons like Enter, Exit, Up, and Down. Some models also include a fifth button known as the I/M button, which stands for Inspection and Maintenance Readiness. This button serves as a shortcut to specific functions.

    If you own an Ancel OBD scanner with the I/M button, such as the Ancel AD410, pressing it will directly access the Quick State Emissions readiness check, as well as other advanced features like the misfire test, smog test, and fuel systems check.

    Another crucial component of an Ancel OBD2 scanner is the cable that is connected to the top of the device. This cable is called the Data Link Connector (DLC) and is plugged into the DLC port inside your car, typically located behind the ashtray on the center console or beneath the dashboard.

    Additionally, Ancel OBD2 scanners come equipped with a USB port that allows you to connect them to a computer. By downloading official firmware updates provided by Ancel, you can keep your code scanner up to date, even years after purchase.

    Store the manual in a safe and easily accessible place, such as your car's glovebox compartment.

    Following Safety Tips and Precautions

    Although Ancel obd2 scanner tool are user-friendly tools, certain precautions must be followed when using them.

    For instance, when connecting your Ancel scanner to your car, ensure that the ignition is off during the process. Only turn it on when prompted by the scanner's screen.

    It is crucial to perform diagnostics with your Ancel device in a safe environment. Ideally, this would be inside your garage with the door open for proper gas ventilation. However, performing scans outdoors while on the road is also feasible. Just ensure that your vehicle is parked in a secure and preferably isolated location. Never use an Ancel OBD2 scanner while driving.

    If you operate an Ancel obd2 bidirectional scanner outdoors, make sure the weather conditions are relatively dry and clear. Ancel devices are not entirely waterproof, so refrain from plugging them into your car if the 16-pin plug or any other part of the scanner is wet.

    Learning to Interpret Diagnostic Trouble Codes

    Diagnostic Trouble Codes (DTCs), also known as engine error codes, play a crucial role when using an Ancel OBD2 scanner. While they may seem complex to some, there are simple rules to follow that will make reading error codes feel intuitive.

    After performing a standard diagnostic analysis, your Ancel OBD2 scanner will display the error codes on its screen. Many people choose to do this when the Check Engine Light on their dashboard illuminates.

    Fortunately, reading engine error codes is straightforward. Pay close attention to the letter that precedes each code. The four letters you will encounter are:

    • P: Stands for Powertrain
    • B: Stands for Body
    • C: Stands for Chassis
    • U: Stands for Unknown. These codes refer to any part of the car not associated with the previous three options.

    Following the letter, a series of four numbers will appear. Together, these letters and numbers constitute the complete error code. Once you have it, you can easily find an online DTC database and enter your code to determine the issue.

    Alternatively, if your Ancel OBD2 scanner has its own built-in DTC database, you can directly look up the error code by entering it into the scanner. This feature is highly convenient, as you can interpret error codes even when you are away from a computer or smartphone.

    Once you have read all the error codes and addressed the issues, it is recommended to erase the codes from the memory of your Ancel scanner. This will prevent confusion in the future when you perform a new scan and encounter new error codes alongside previously resolved ones from months or even years ago.

In fact, you might regret not starting to use it sooner!

Remember to keep it with you in your vehicle at all times, just in case!
