While the first attempt might feel slightly challenging, subsequent uses will become increasingly easier and more efficient. But before we dive into the directions, let’s clarify: what exactly is an OBD2 scanner?
Understanding the OBD2 Scanner
An OBD2 scanner is a portable electronic tool designed to interface with your vehicle’s onboard computer, known as the Engine Control Unit (ECU). This connection empowers the scanner to perform a range of crucial diagnostic functions, including:
- Reading Diagnostic Trouble Codes (DTCs): These codes are your car’s way of communicating problems.
- Performing Emissions Tests: Ensuring your vehicle meets environmental standards.
- Displaying Live Engine Performance Data: Providing real-time insights into how your engine is running.
- Viewing Freeze Frame Data: Capturing specific data snapshots when a fault code is triggered.
- Analyzing Engine and Fuel System Parameters: Helping optimize engine efficiency.
- Inspecting Critical Systems: Checking the health of systems like the Anti-lock Braking System (ABS) and Supplemental Restraint System (SRS).
- Adjusting Computer Settings: On some advanced models, you can even customize settings like door lock behavior.
While professional-grade scanners offer the full spectrum of these capabilities, mid-range Ancel scanners are equipped to handle most, and even budget-friendly models effectively perform core functions like reading engine error codes, conducting emissions tests, and displaying essential live engine data. For basic car diagnostics, even an entry-level Ancel code reader is a powerful tool.
Step-by-Step Ancel OBD2 Scanner Directions
Ancel OBD2 scanners are available with varying features and functionalities, typically reflected in their price point. You’ll find both corded handheld scanners and wireless Bluetooth-enabled versions. Bluetooth models connect seamlessly to your smartphone, and some even come bundled with dedicated tablets for enhanced usability. Here’s a detailed guide on how to use your Ancel scanner effectively:
Step 1: Pinpointing the OBD2 Port Location
Since 1996, all vehicles manufactured for sale in the US have been equipped with a standardized On-Board Diagnostics II (OBD2) port. This port, officially termed the Diagnostic Link Connector (DLC), is your gateway to accessing your car’s computer. In most vehicles, you’ll find the OBD2 port located beneath the dashboard on the driver’s side, often to the left of the steering column. However, its exact placement can vary. Sometimes it’s positioned further under the dash, requiring you to bend down to see it clearly.
The OBD2 port is easily recognizable by its trapezoidal shape and 16 female pins. In some vehicle models, it might be situated on the passenger side of the dash or even within the center console. If you are unable to locate it visually, consulting your vehicle’s owner’s manual is always a helpful step.
Step 2: Establishing the Connection with Your Ancel OBD2 Scanner
Once you’ve located the OBD2 port, the next step is to connect your Ancel diagnostic tool. Crucially, ensure your vehicle’s ignition is turned off before proceeding with this connection. Ancel OBD2 scanners come in two primary designs: wired handheld scanners and Bluetooth modules.
For a handheld scanner, simply connect the cable end securely into the OBD2 port. Listen for a click to ensure a firm connection. For Bluetooth-enabled scanners, the module itself plugs directly into the OBD2 port. After physically connecting the Bluetooth module, you’ll need to establish a wireless connection with your smartphone or the scanner’s dedicated tablet. Make sure you have the Ancel app installed on your phone; versions are readily available for both iOS from the App Store and Android from the Google Play Store.
Step 3: Powering Up and Inputting Vehicle Information
Some Ancel scanners are designed to be self-powered, drawing energy directly from the OBD2 port. These models may not require you to turn the vehicle’s ignition to the “accessory” or “on” position to begin reading codes. However, other scanners might need the ignition to be in the “on” position (without starting the engine) to power up. Always refer to your Ancel scanner’s user manual for specific power-up instructions. Remember, the engine should remain off while the scanner is actively performing diagnostics.
Depending on the Ancel scanner model, you might be prompted to input vehicle-specific information, such as the Vehicle Identification Number (VIN), to allow the tool to correctly identify your car. You might also be asked for the vehicle’s year, make, and engine type. Enter this information accurately when requested. The VIN is typically located on the dashboard near the windshield on the driver’s side and is also found on your vehicle’s registration and insurance documents. More advanced Ancel scanners, like the Ancel AD410, are often capable of automatically retrieving this information directly from the vehicle, streamlining the process.

Step 4: Interpreting Diagnostic Trouble Codes (DTCs)
Once the Ancel scanner has successfully gathered information about your vehicle, it will initiate a scan of your car’s systems. After scanning, the tool will display any Diagnostic Trouble Codes (DTCs) currently stored in the ECU’s memory. Some Ancel scanners will present a menu-driven interface, allowing you to select specific vehicle systems you wish to diagnose. Others might directly display a comprehensive list of all detected error codes, which you can then scroll through.
You’ll encounter two primary categories of DTCs:
- Active Codes: These DTCs are currently triggering the check engine light (CEL) or malfunction indicator lamp (MIL) and indicate issues that require immediate attention.
- Pending Codes: These DTCs relate to intermittent or potential issues, often concerning emissions control systems. Pending codes may not illuminate the CEL initially, but they can escalate into active codes if the underlying problems worsen or persist.
Active codes, especially those triggering the check engine light, are the primary reason for using an OBD2 scanner. Addressing these codes promptly is crucial for maintaining your vehicle’s health and performance.
Step 5: Decoding the Meaning of Fault Codes
The diagnostic tool will present fault codes in a standardized format: a letter followed by four numerical digits, for example, “P0427”. Understanding the structure of these codes is key to interpreting the diagnostic information.
- B (Body): Codes starting with “B” indicate faults within the vehicle’s body systems, such as airbags, seatbelts, power windows, and power steering.
- P (Powertrain): “P” codes are the most common and relate to powertrain issues, encompassing the engine, transmission, fuel system, emission controls, and ignition system.
- C (Chassis): “C” codes point to problems within the chassis systems, including the anti-lock braking system (ABS), brake fluid levels, traction control, and axle-related issues.
- U (Undefined/Network): “U” codes signal communication or network-related issues within the vehicle’s computer systems. These can be more complex and often require professional diagnosis.
The first digit following the letter further refines the code’s meaning: “0” typically indicates a generic code, standardized across all manufacturers, while “1” signifies a manufacturer-specific code, unique to a particular car brand. The subsequent numbers pinpoint the specific faulty component or circuit and the nature of the problem. Some Ancel scanners are equipped with built-in code definitions, displaying explanations directly on the screen. For scanners without this feature, a quick online search for the specific DTC will readily provide its meaning.
Step 6: Clearing Fault Codes (After Addressing Issues)
After you’ve successfully diagnosed the issue using the fault codes, performed the necessary repairs or component replacements, the check engine light should automatically turn off in many cases. However, you can also manually clear the stored fault codes and turn off the CEL using your Ancel scanner.
Most Ancel scanners have a “Clear Codes” or “Erase Codes” function within their menu. It’s important to note that clearing codes should ideally be done after you have addressed the underlying problem. While clearing codes will turn off the check engine light, it does not fix the actual issue. If the problem persists, the check engine light will likely reappear, and the same fault codes will be logged again. Clearing codes prematurely without fixing the fault can mask symptoms and potentially lead to more significant problems down the road.
