“Collision detected” on mower no collision and can’t clear

Made a ticket but just took mower out for season and going over some rough ground I had no issues with before and yarbo stopped for a collision. Was able to clear but would always come back after a few seconds. Now I can’t get it to clear at all. The bumper doesn’t look damaged but can’t seem to fix even with reboots and disconnects.

Anyone else have this happen?

Did you happen to store the mower module on the bumper? I know someone who had this issue when the stored it with pressure on the bumper and after a few days it solved itself. However, here is some troubleshooting steps to follow if not.

I did store it vertically but I had thought I had it sitting not on the bumper but the front. I’ll watch it over the next day or two and see if that helps

It did seem to sort itself out after a hour or so horizontal.

Thank goodness!

Mine did that when I wanted to start using it this spring. I unplugged the bumper sensor and been running it like that ever since. But mine mows around my chicken barns where most of the time it’s not going to hurt much if it hits something

I had a bumper failure last year. It started as very intermittent collision warnings and progressively got worse. Keep an eye on it.

Glad to hear the issue has been resolved.

If it happens again in the future, please feel free to submit a support ticket so our team can take a closer look and assist you further.

Thanks for keeping us updated!

I encountered the same issue. I replaced the lawnmower module yesterday and everything seemed to work normally.

Today, when I opened the app, it reported Collision Occurred. A standard restart or swapping the module didn’t make any difference.

I opened a ticket #186524

Did you try disconnecting the battery for 5 mins? Clear error, shutdown, unplug battery.

Hate to bring it up again, but this is exactly what I was seeing with a bumper sensor problem. Hopefully not.

I’ve located your support ticket in our system.

As our support team suggested, could you please try removing the bumper from the lawn mower and then check whether the app still shows the “Collision Occurred” error? This will help us determine if the issue might be related to the bumper sensor.

Once you’ve had a chance to test this, feel free to let us know the result—we’ll take it from there and continue to assist you.

I didn’t disconnect the battery, and clearing the error didn’t have any effect.

But after leaving it overnight, the error seems to have disappeared and everything appears to be working normally again.

Hopefully it was just a temporary glitch.

Btw. I also stored the module horizontally throughout the winter."

Thanks, but after leaving it overnight, the error seems to have disappeared and everything appears to be working normally again.

Hopefully it was just a temporary glitch.

That can do it. It seems to have a memory of sorts when stored on the bumper. Hopefully that’s all it was and you no longer have any issues for the rest of the season!

Argh, the issue came back, and neither disconnecting the battery nor clearing the error had any effect.

However, I noticed that the error appeared after I connected the trimmer to the core, and when I removed it, the error disappeared after a few hours, asit had come

If the trimmer really is the cause (I’m waiting for support to respond — hopefully @Yarbo-Forum can help with this), it’s a rather strange error message in my opinion, and I don’t understand why it takes hours for the error to appear and then disappear.

That’s a new one! Haven’t seen that before. Definitely very strange.

Hi there, thanks for sharing the detailed observations — that’s really helpful.

We haven’t seen similar cases reported so far. I’ve checked your support ticket, and our team is already looking into it to identify the root cause.

We appreciate your patience while we investigate further. In the meantime, please feel free to let me know if there’s anything I can assist with regarding your support ticket.

OMG, and now the error returned. In the meantime, Core has just been lying on the docking station.

I now removed the battery (+5 min) and restarted it. Let’s see what happens next.
