7.1. Step 1: Locate the OBD2 Port in Your Mercedes-Benz

The OBD2 port is typically located under the dashboard on the driver’s side. According to the Society of Automotive Engineers (SAE), all vehicles manufactured after 1996 are required to have a standardized OBD2 port, making it easier to access diagnostic information.

• Common Locations: Under the dash, near the steering column.
• Check Your Manual: If you can’t find it, consult your vehicle’s owner’s manual.

7.2. Step 2: Connect the Ancel OBD2 Scanner to the Port

Ensure your vehicle is turned off before connecting the scanner. This prevents any potential electrical issues during the connection process.

• Wired Scanners: Plug the cable end directly into the OBD2 port.
• Bluetooth Scanners: Plug the Bluetooth module into the OBD2 port.

7.3. Step 3: Turn On the Ignition and Input Vehicle Information

Some scanners require the ignition to be in the “ON” position (but engine off) to read data. Inputting the correct vehicle information ensures accurate diagnostics.

• Follow Scanner Prompts: Enter the VIN, model, and engine type when prompted.
• VIN Location: Found on the driver’s side windshield or door jamb.

7.4. Step 4: Read and Interpret Diagnostic Trouble Codes (DTCs)

Once connected, the scanner will display any stored DTCs. Understanding these codes is essential for diagnosing the problem.

• Active Codes: Indicate current issues that need immediate attention.
• Pending Codes: Suggest potential problems that may require further investigation.
• Code Definitions: Use the scanner’s built-in database or online resources to look up code meanings.

7.5. Step 5: Understand the Meaning of the Codes
