S660 Active Hood Fault

I've got a 2020 Honda S660 (gasoline engine) with about 66840 km on the clock. Recently, I've been getting an "Active hood fault" message on the on-board computer, and the airbag warning light is on in the speedometer. I checked the error memory, and it shows a fault related to the active hood system. It seems the spring actuators were triggered. Anyone else run into this? Thinking it might be the acceleration sensor, but wanted to see if anyone has experience.

Summary of the thread

A 2020 Honda S660 owner reported an "Active hood fault" message and an airbag warning light, indicating a problem with the active hood system. The issue was suspected to be related to the acceleration sensor, as the spring actuators were triggered without any recent front-end work. After consulting with others, it was confirmed that the acceleration sensor was indeed faulty, and the owner had it repaired at a workshop.

Did this summary help you solve your problem?

Sounds like a possible acceleration sensor issue, yeah. Is the error consistently appearing, or is it intermittent? Have you had any work done on the front of the car recently?

The error is pretty consistent now. It started off intermittent, but now it's always there when I start the car. And no, haven't had any work done on the front end lately. Just regular maintenance.

Okay, given that it's consistent and no recent work has been done, a faulty acceleration sensor is a likely culprit. Unfortunately, it’s part of the collision detection system, so it's best to get it checked out by a workshop to confirm.

Thanks for the advice! Took it to a shop, and you were right, it was the acceleration sensor. Repair came out to 315€. Appreciate the help!
