3. Power on the Scanner:
   • The OBD2 scanner should power on automatically. If it doesn’t, check the power button and turn it on.

5.3. Reading Diagnostic Trouble Codes (DTCs)

1. Navigate the Scanner Menu:
   • Use the scanner’s buttons to navigate to the main menu. Look for options like “Read Codes,” “Diagnostic Codes,” or similar.
2. Select “Read Codes”:
   • Choose the appropriate option to read the diagnostic trouble codes (DTCs) stored in the vehicle’s computer.
3. View the Codes:
   • The scanner will display any stored DTCs. Note down the codes for further research.
4. Understand the Codes:
   • Refer to the scanner’s manual or an online database (like the one provided by MERCEDES-DIAGNOSTIC-TOOL.EDU.VN) to understand the meaning of each code. DTCs are typically five-character codes, such as P0301 (misfire in cylinder 1).

5.4. Interpreting the Data

1. Research the Codes:
   • Use reliable sources to understand the potential causes and solutions for each DTC. Common resources include online forums, repair manuals, and diagnostic websites.
2. Prioritize Issues:
   • Some codes are more critical than others. Prioritize diagnosing and addressing the most severe issues first.
3. Check Freeze Frame Data:
   • If available, review the freeze frame data associated with each DTC. This data provides a snapshot of the vehicle’s condition when the code was triggered, which can help in diagnosing the problem.

5.5. Clearing the Diagnostic Trouble Codes (DTCs)

1. Address the Issues:
   • Repair or replace any faulty components identified during the diagnostic process.
2. Navigate to “Erase Codes”:
   • Once the issues are resolved, use the scanner’s menu to find the “Erase Codes,” “Clear Codes,” or similar option.
