Using an Ayetools OBD2 scanner is straightforward. Here’s a step-by-step guide to get you started:

3.1. Step 1: Locate the Diagnostic Link Connector (DLC) in Your Mercedes-Benz

The DLC, also known as the OBD2 port, is a 16-pin connector typically located under the dashboard on the driver’s side of your Mercedes-Benz. It may be covered by a small flap or panel. If you’re having trouble finding it, consult your vehicle’s owner’s manual.

3.2. Step 2: Connect the Ayetools OBD2 Scanner

Turn off your Mercedes-Benz before connecting the scanner. Plug the OBD2 connector of the Ayetools scanner into the DLC. Ensure the connection is secure.

3.3. Step 3: Power On the Scanner and Vehicle

Turn the ignition to the “ON” position without starting the engine. This provides power to the vehicle’s electrical system and allows the scanner to communicate with the car’s computer. Power on the Ayetools OBD2 scanner. It should automatically detect the connection to your Mercedes-Benz.

3.4. Step 4: Navigate the Scanner Menu

Use the scanner’s buttons to navigate the menu. The options may vary depending on the specific Ayetools model, but common options include:

• Read Codes: This option displays any stored or pending diagnostic trouble codes (DTCs).
• Clear Codes: This option erases stored DTCs. Use this with caution, as it can also erase important diagnostic data.
• Live Data: This option displays real-time data from various sensors and systems in your vehicle.
• Freeze Frame: This option displays data from the moment a DTC was triggered.
• I/M Readiness: This option checks if your vehicle is ready for emissions testing.
• Vehicle Info: This option displays your vehicle’s VIN and other important information.

3.5. Step 5: Read and Interpret Diagnostic Trouble Codes (DTCs)

Select the “Read Codes” option to view any stored DTCs. Each code consists of a letter followed by four numbers. The letter indicates the system affected:

• P: Powertrain (engine, transmission)
• B: Body (airbags, lighting, power windows)
• C: Chassis (ABS, suspension)
• U: Network (communication between control units)

The numbers provide more specific information about the fault. Consult an OBD2 code database or repair manual to understand the meaning of each code. Many Ayetools scanners also provide a brief description of the code on the screen.

3.6. Step 6: Analyze Live Data (Optional)

The “Live Data” option allows you to monitor various sensors and systems in real-time. This can be helpful for diagnosing intermittent problems or verifying the performance of specific components.

3.7. Step 7: Clear Codes (Optional, Use with Caution)

After addressing the underlying issue, you can use the “Clear Codes” option to erase the stored DTCs and turn off the check engine light. However, it’s essential to understand why the code was triggered in the first place. Clearing codes without fixing the problem will only result in the light coming back on.
