What the app can do

The NVH app is designed to automatically detect the type of vibration your vehicle is experiencing, provided the instructions of the road test procedure are followed.

There are 14 types of vibrations the NVH app can automatically detect:

  • Tire speed-related (1st, 2nd, and 3rd order vibrations)
  • Driveshaft speed-related (1st, 2nd, and 3rd order vibrations)
  • Engine speed-related (0.5, 1st, 2nd, 3rd, 4th, 5th, and 6th order vibrations)
  • Electric Motor Speed Related (1st order vibrations)

Each type of vibration has unique causes. A vibration type is not the same thing as a vibration source. There are many possible causes (sources) for each vibration type. The NVH app includes step-by-step instructions on locating the vibration source once the app has identified the type of vibration.

What the app cannot do

  •  The NVH App cannot automatically tell you the source of a vibration
  • Although the NVH app is excellent at identifying the type of vibration your vehicle is experiencing, you or someone else will need to follow the diagnostic steps described in the app help files to identify the exact cause or source of the vibration.

There are almost 300 possible sources of vibration concerns in today’s vehicles
