I have located the 2015 Prius noisemaker. It looks like if you wanted to access its function, it is easy and so is locating its plug. As pictured, it's located on top whereas earlier models were located at the bottom deep inside the engine. I am not sure when the location change occurred. Of course this is for educational purposes only. What you do with it as well as its consequences is your decision. To learn about the Prius, I have tested the car without it and I can't really notice any difference. I wonder if it's the more distinct buzzing noise (over the inherent electric buzzy noise) that is the difference. I'll have to test again.
I disconnected my awhile. I did not put a cap on the plug. Wonder if they make one. It might rust in the long run.
Hoping to figure out how to hack a different sound (Tardis hum) into mine. My project Prius "v" chassis has its noise maker located ahead of the left front tire. Bill the Engineer
Here's hoping it's more useful than the older noisemakers. Mine's about as useful as a purring kitten.
I'm not saying it isn't a thoughtful safety device for blind pedestrians. I just think it would be just as useful with a less obnoxious or more recognizable sound. The present sound is more like an egg beater rapping against an empty mixing bowl rather than the sound a car would make. Bill the Engineer
^ That sounds like fun. One thing, I wouldn't categorize the sound maker as being only for blind pedestrians. Anyone walking ahead of you, say in a parking lot or a lane, could benefit from hearing a bit more noise than the sound of tires.
mine has a hard to describe whistling, humming whiny sound, maybe like the wind at times. can't hear it with the windows up, barrel outside and most pronounced in the garage. i would prefer silent running but fear big brother will be requiring more noise. i like sneaking up on people texting while walking down the middle of the isles in parking lots, and giving them a blast on the horn.
