Maybe this will help - I didn’t do a real world test: Link
I think the school sign identification is part of the same system that displays the speed limit sign too.
Mine does the same thing. I thought there might be an issue with my rear seat sensor, but the warning light disappears after 15 sec or so, same as yours. I just chalk it up to an extended warning sign imposed by Toyota.
This is top shelf reverse engineering. Great work, guys. I know you’re talking about the ORP, but can you clarify if this is gas-only, hybrid, or both?
It's also useful to see when the 4runner brakes for you as part of one of the safety features - and I wish it wouldn't brake so soon (and I have it on the minimum setting)
I took off my air dam and replaced the screws. I have a TRD ORP. I don’t notice any difference in noises while driving, and I don’t hear a whistle.
