The error code specifically points to the fuel filter heater circuit. I have visually inspected the wiring harness for obvious damage, but found nothing. Are there any specific points of failure common to this component in the BR-V that I should investigate further before replacing parts?

Given the specific error code and your inspection, it does seem the fuel filter heater or its connection is the likely culprit. Further diagnostics might require specialized tools. I would suggest consulting a workshop for a definitive diagnosis to avoid unnecessary parts replacement.

Thank you for the advice. I took it to a workshop, and the issue was indeed a corroded connector on the fuel filter heater. The repair cost 95€, including parts and labor.

That is unusual for such low mileage. Are you certain about the fuel filter heater being the root cause? Have you checked for any other error codes or performed any diagnostics beyond reading the error memory?
