Step-by-Step Guide to Clearing Trouble Codes

Now that you’ve gathered the necessary tools and familiarized yourself with the common trouble codes, let’s dive into the step-by-step process of clearing trouble codes on your 2018 Mercedes-Benz C43 AMG Sedan.

1. Locate the OBD2 Port

The first step is to locate the OBD2 port in your C43 AMG. This port is typically located under the dashboard, on the driver’s side, and provides access to the vehicle’s diagnostic system.

2. Connect the OBD2 Scanner

With the OBD2 port identified, carefully connect your OBD2 scanner to the port. Ensure a secure and proper connection to ensure accurate readings and code clearing.

3. Retrieve the Trouble Codes

Turn on the OBD2 scanner and navigate to the “Read Codes” or “Trouble Codes” function. Your scanner will then display the active diagnostic trouble codes present in your C43 AMG’s computer system.

4. Understand the Trouble Codes

Refer to the earlier section on common trouble codes to gain a better understanding of the specific issues affecting your vehicle. This knowledge will help you determine the appropriate troubleshooting and repair steps.

With the trouble codes displayed, locate the “Clear Codes” or “Erase Codes” function on your OBD2 scanner. Initiate the code-clearing process, which will remove the stored trouble codes from your Mercedes-Benz’s computer.

6. Verify the Codes are Cleared

After clearing the codes, your OBD2 scanner should indicate that the process was successful, and the “check engine” light on your dashboard should be extinguished. If the light persists, it’s possible that the underlying issue has not been fully resolved, and you may need to perform further diagnostics and repairs.
