How To Reset Honda U3485 Code ?

To reset the U3485 diagnostic trouble code (DTCs) in your Honda vehicle, you will need to use a diagnostic tool, such as a scan tool or a code reader. The exact process for resetting the U3485 DTC will vary depending on the specific make and model of your Honda, as well as the diagnostic tool you are using. Here are the general steps you can follow:

1. Connect the diagnostic tool to your Honda's onboard diagnostic (OBD) port, which is typically located under the dashboard on the driver's side.
2. Follow the instructions on the diagnostic tool to access the DTCs. Some diagnostic tools will have a specific button or menu option for this.
3. Locate the DTCs that you want to reset. The diagnostic tool will display the codes and their associated descriptions.
4. Clear or reset the DTCs using the diagnostic tool. The process for doing this will vary depending on the tool you are using. Some diagnostic tools may have a specific button or menu option for clearing the codes, while others may require you to enter a specific command or sequence of buttons.
5. Once the DTCs have been cleared, start the engine and let it run for a few minutes to ensure that the codes do not reappear.

It's worth noting that resetting DTCs without addressing the underlying issue that caused the codes to appear in the first place will not solve the problem and the DTCs will likely reappear. If the DTCs persist after resetting, it's recommended to take the vehicle to a professional mechanic to diagnose and fix the problem.
