Engine over run warning on Hino 258

[b.t.45wilson]

I just bought a used 2020 Hino 258 with around 70,000 miles on it, and I'm a little worried about a warning that just popped up. I took it on its usual route today, nothing out of the ordinary, and after I shut the truck off, a warning came up on the dash that says "Engine over run. After operating, request engine maintenance." The truck seems to be running fine, no weird noises or anything, but that's a pretty concerning message. Anyone here who got the same message on their truck, specifically a 2020? I'm trying to figure out what the likely cause is and if it's a common issue with a relatively simple fix. I did a thorough inspection pre-purchase so I'm hoping it's not a serious problem. Any advice would be a huge help. Thanks!

I've seen that message before on a Hino, it is usually tied to high idle or engine braking too long. It's more of a service reminder than a failure

Get it scanned to see what's stored in the ECU just to be safe cos that message probably means the engine was revved higher than expected under load, or possibly for too long a duration
Might not be a serious damage anyway

If everything sounds and feels normal, it's likely just a maintenance reminder. Still, a quick scan with a diagnostic tool or a visit to a Hino tech wouldn't hurt for peace of mind.
