Operating an Ancel OBD2 reader is surprisingly straightforward. You don’t need advanced automotive knowledge to effectively use one. All it takes is a bit of guidance, which we’ll provide here. While your first time might feel slightly unfamiliar, subsequent uses will become second nature.
But first, for those new to this technology, what exactly is an OBD2 scanner?
Understanding the OBD2 Scanner
An OBD2 scanner is a portable electronic tool that connects to your vehicle’s onboard computer, often referred to as the Engine Control Unit (ECU). This connection unlocks a wealth of diagnostic capabilities, allowing you to:
- Read Diagnostic Trouble Codes (DTCs): These codes are essentially error messages from your car’s computer, indicating potential issues.
- Perform Emissions Tests: Check if your vehicle is meeting emissions standards.
- View Live Engine Data: Monitor real-time performance metrics of your engine.
- Access Freeze Frame Data: See the data captured by the ECU at the moment a fault code was triggered.
- Explore Engine and Fuel System Parameters: Gain deeper insights into engine performance and potential optimization.
- Inspect Critical Systems: Check systems beyond the engine, such as the Anti-lock Braking System (ABS) and Supplemental Restraint System (SRS).
- Adjust Computer Settings: Some advanced scanners even allow for customization of vehicle settings like door lock behavior.
While high-end professional scanners offer all these features, mid-range Ancel scanners typically provide a substantial portion of them. Even entry-level, budget-friendly Ancel code readers will cover the essential functions: reading engine error codes, conducting emissions tests, and displaying live engine data.
Step-by-Step Ancel OBD2 Reader Instructions
Ancel OBD2 scanners are designed with varying features, with more advanced models offering expanded functionalities. You’ll find both corded handheld scanners and wireless Bluetooth-enabled versions. Bluetooth models often connect to your smartphone or come with dedicated tablets for data display. Here’s a detailed guide on how to use your Ancel scanner:
Step 1: Finding the OBD2 Port in Your Vehicle
Since 1996, all vehicles manufactured for the US market are equipped with a standardized On-Board Diagnostics port, known as OBD2. This port is also commonly referred to as the Diagnostic Link Connector (DLC). In most cars and trucks, you’ll find the OBD2 port located beneath the dashboard on the driver’s side. It’s usually situated to the left of the steering column. However, the exact placement can vary; sometimes it’s positioned further under the dash, requiring you to bend down to see it.
The OBD2 port is easily recognizable by its trapezoidal shape and 16 pinholes (female pins). In some vehicle models, the port might be on the passenger side of the dashboard or even in the center console. If you’re having trouble locating it, your vehicle’s owner’s manual will provide the precise location.
Step 2: Connecting Your Ancel OBD2 Scanner to the Port
Once you have located the OBD2 port in your car, the next step is to connect your Ancel diagnostic tool. Ensure your vehicle’s ignition is turned off before proceeding with this connection. Ancel OBD2 scanners come in several configurations. Some are handheld devices with a cable that plugs into the OBD2 port, while others are Bluetooth modules that wirelessly connect.
For wired handheld scanners, simply insert the connector end of the cable firmly into the OBD2 port. For Bluetooth scanners, the module itself plugs directly into the OBD2 port. If using a Bluetooth scanner, you will also need to ensure the Ancel app is installed on your smartphone or tablet. The Ancel app is available for both iOS devices on the App Store and Android devices on the Google Play Store.
Step 3: Powering Up and Vehicle Information Input
Depending on the specific Ancel scanner model, the power source might vary. Certain Ancel scanners are self-powered, drawing power directly from the OBD2 port. For these models, you may not need to turn on your vehicle’s ignition to access and read codes. However, other scanners might require the vehicle to be in the “key-on, engine-off” position (ignition turned to accessory mode) to power up. It’s important to note that the engine should remain off throughout the scanning process.
Some Ancel scanners will prompt you to enter vehicle-specific information, such as the Vehicle Identification Number (VIN), to correctly identify your car. You might also be asked for the vehicle’s make, model, and engine type. Accurately input this information as requested by the scanner. The VIN is typically located on the dashboard near the base of the windshield on the driver’s side. More advanced Ancel scanners are often capable of automatically retrieving this information directly from the vehicle’s computer, simplifying the process.

Step 4: Interpreting Fault Codes and Diagnostic Results
After the scanner establishes a connection and gathers vehicle information, it will initiate a scan of your car’s systems. The scanner will then display any Diagnostic Trouble Codes (DTCs) that are currently stored in the ECU’s memory. Some Ancel code readers present a menu, allowing you to select specific vehicle systems you wish to diagnose. Others will directly display a list of all detected error codes, which you can then scroll through.
Within the DTCs, you’ll typically encounter two categories:
- Active Codes: These DTCs are currently triggering the check engine light or other warning indicators. Active codes signal immediate issues that need to be addressed promptly.
- Pending Codes: These DTCs relate to intermittent or potential issues, often concerning emissions control. Pending codes may not illuminate the check engine light initially but can escalate into active codes if the underlying problems worsen or persist.
The illumination of the check engine light is frequently triggered by active codes, sometimes developing from unresolved pending codes. These active codes require your immediate attention to prevent further vehicle damage or performance issues.
Step 5: Deciphering the Meaning of Error Codes
Diagnostic trouble codes are standardized and consist of a letter followed by four numerical digits. A common example is “P0427.” Once you retrieve these codes using your Ancel scanner, the next crucial step is to understand their meaning. The initial letter of the code indicates the affected vehicle system:
- B (Body): Codes in this category relate to the vehicle’s body systems, such as airbags, seatbelts, power windows, and power steering.
- P (Powertrain): “P” codes indicate issues within the powertrain system, which includes the engine, transmission, fuel system, emission controls, and ignition system.
- C (Chassis): “C” codes point to problems related to the chassis, encompassing components like the anti-lock braking system (ABS), brake fluids, suspension, and axle issues.
- U (Undefined/Network): “U” codes signify communication or network-related problems within the vehicle’s computer systems and do not fall into the Body, Powertrain, or Chassis categories.
The first digit following the letter provides further specificity: “0” typically denotes a generic code (standard across manufacturers), while “1” indicates a manufacturer-specific code (unique to a particular car brand). The subsequent numbers provide more granular detail about the specific faulty component and the nature of the problem.
Some advanced Ancel scanners are equipped with built-in code definitions, providing an on-screen explanation of the fault codes. For other models, you may need to consult your Ancel scanner’s manual or use online resources, such as a quick Google search for the specific code, to determine its meaning and potential causes.
Step 6: Clearing Fault Codes After Repairs
After you have correctly diagnosed the issue based on the fault codes, performed the necessary repairs, and replaced any faulty components, the check engine light (CEL) should automatically turn off in most cases. However, if the CEL remains illuminated, or if you wish to clear the codes after addressing the problem, you can use your Ancel scanner to manually erase the fault codes.
Most Ancel scanners have the capability to clear DTCs and turn off the check engine light, even if the underlying issues haven’t been fully resolved. However, it is crucial to only erase codes after you have properly diagnosed and repaired the problem. Clearing codes without fixing the root cause will only temporarily turn off the warning light, and the issue will likely reappear, potentially leading to more significant problems down the road.
