Pico NVH case study
Check out my case study on this Silverado front end noise using the pico Nvh kit. thanks guys
didnt say in video but i did place accelerometer on all suspension and steering components and most noise/vibration was at caliper
Thanks for the video Aaron, Typically noises like that come into many shops and they instantly want to shotgun ball joints on the vehicle. I have used a Steelman Chassis Ear for many years and it is not as advanced as the PICO NVH but it works through piezo electric microphones. When I worked at the dealer I used NVH test equipment quite often and the other techs typically avoided the…
I absolutely agree with testing first and using technology available to us. thank for you input and you worked at a gm dealer ? i heard gm dealers have nvh kits
Hi Aaron, I worked at a local Ford dealer at the time. That is what prompted me to buy an NVH test set. I don't use it very often, but it is nice to have when I need it. I even use a sonic leak detector once in a while from my body shop days. If you want to focus on weird noise diagnostics, look at body shops. They have them practically every day.
Hi Aaron. Good job. The NVH kit was developed for GM with Pico. There was a rumour that Toyota was initially involved, but that the project stalled. I can't substantiate that, but use the tool as first brought to market for GM. It used a single axis sensor that was soon replaced with a 3 axis sensor. BTW, don't forget to disconnect the cables from any internal battery powered modules, or the…
Thank you gor all this very valuable information Martin will definitely refer to this 💪
All you have proven is the vibration/or noise could be heard better at the brake caliper by the NVH sensor. I would be interested to see an after capture if you change the brakes. The suspension could be more your issue but keep us posted. Thanks for your post
I did put it on all suspension and steering components as well, and the most g’s mg’s were recorded on brake caliper, i will do another capture post repairs
Thanx for sharing Arron, that tool is pretty cool , I wonder if autel makes something like that for there ultra scanner /scope , I have the Matco wireless chassis ears to get me by guess I will be doing some research. Thanx Mr Pena
I feel like nvh offers much more than what i did in that video but i need more time and practice with it. thanks !
Hi Raymond, Autel has not ventured that direction yet that I know of. The only other one I am familiar with is the ATS system. They have a mic option that can be plugged into their scope. Of course ATS is the top of the line, but that is my personal opinion. There is also a NVH program download available for smart phones and tablets that have GPS built in (not sure of the accuracy). I see the…
There are many examples like this on the web. Using the Picoscope NVH kit to find a drive-line vibration - Bing video
Yes that was a cool video as well thanks for sharing Glenn
