The PicoDiagnostics NVH Kit from Pico Technology is the cost-effective answer to the many NVH problems facing technicians today. Providing real-time diagnosis to the technician in the form of either: a bar graph, a frequency chart, a 3D frequency chart, RPM order or road speed view. The ability to start the recording before a road test, and play back the recording for analysis on your return, ensures that driver attention remains on the road. Saving the recordings couldn’t be simpler: much like our other automotive software you simply save the file to your laptop’s hard drive.

The PicoDiagnostics NVH kit makes use of the PicoScope 4000 Series Automotive oscilloscope, and is available in a number of configurations to suit your needs (J2534 Scan Tool or VCI not supplied). You can be sure that your investment in the PicoDiagnostics NVH kit will benefit your business without the need for further spending. If you already have a PicoScope 4000 Series Automotive oscilloscope, you’re halfway there.

Typical uses

Customer complaints surrounding noise/vibration are subjective at best and present technicians with a challenge before diagnosis and rectification begins. Applying the NVH kit to the vehicle will allow the technician to road-test the vehicle with the customer to obtain all vibration and noise levels. Once this valuable data has been collected it can be analyzed and compared to previous captures or against donor vehicles. Often what is perceived by the customer to be a “problem” vibration is in fact a characteristic. Now you can present and compare objective data with test results from donor vehicles to reassure your customer all is OK. Alternatively, comparing data may highlight a problem within the vehicle allowing the technician to proceed to a repair with confidence supported by measurements taken. Below are just a few of the typical scenarios where the NVH kit can save time and money:

  • Cabin vibrations at speed
  • Engine vibrations throughout the entire RPM range
  • Clutch judder or vibration
  • Transmission and bearing whine
  • Auxiliary drive noise
  • Brake judder
  • Steering vibrations
