S660 ECU Problem
Summary of the thread
A 2018 Honda S660 with a gasoline engine is experiencing an ECU problem, resulting in a loss of power and an error code. A similar issue was resolved by checking the main relay, which can cut off power and cause error codes. Replacing the defective main relay fixed the problem at a cost of 120€.

Main relay, huh? Where is that located? And what exactly did it do?

It's part of the vehicle electronics, it completely cuts off power. I didn't check the exact location as I brought it to the workshop. They said it can cause the error code you mentioned.

Thanks. Seems like the main relay was defective. Cost 120€ to fix. Appreciate the heads-up!

I had something similar happen on my S660. Same symptoms. Did you check the main relay? That was the likely cause for me.
