How Do You Clear Codes on a Semi Truck?

Clearing codes from your semi-truck is a critical step in diagnosing and addressing mechanical problems. When a semi-truck throws an error code, it is necessary to clear the code before the truck can be used again.

Fortunately, clearing codes on a semi-truck is not as difficult as it may seem. Here are some tips and instructions on how to clear codes on a semi-truck.

Step 1: Locate the diagnostic port on your truck. This port is usually located under the driver’s seat or in the cab area of the vehicle. It should be marked with a label that says “Diagnostic Port”.

Step 2: Connect your diagnostic tool to the diagnostic port. Depending on what type of tool you are using, you may need to plug it into your laptop or connect it directly to the port.

Step 3: Run a scan with your diagnostic tool. The scan will detect any error codes stored in the truck’s computer system.

Step 4: Clear any error codes that were discovered during the scan. This can be done either manually or automatically depending on what type of tool you are using.

Conclusion:
Clearing codes on a semi-truck is not complicated, but it is an important step in diagnosing and solving mechanical problems. By following these steps and using a reliable diagnostic tool, you can quickly and easily clear any stored codes from your truck’s system.
