Vibrate Software Description and Operation

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The J 38792-VS , Vibrate Software, is a computer software program which is designed to be used in support of the Vibration Analysis diagnostic tables, along with the J 38792-A , Electronic Vibration Analyzer (EVA) and a scan tool, to help in determining the source of a vibration concern. See Special Tools . The J 38792-VS is designed to provide quick calculations and produce a chart of the rotational speeds and frequency ranges for specific vehicle systems and components, based upon vehicle data parameters inputted by the user. See Special Tools .

The J 38792-VS uses the vehicle data parameters, such as axle ratio, number of engine cylinders, etc. See Special Tools . to create the base chart, depicting the relationships of the various vehicle systems and/or components. The chart view can be modified to show data related to vehicle speed only, engine speed only, or both vehicle speed and engine speed. The user can then plot the dominant frequency reading obtained on the J 38792-A which correlates with the vibration concern, and the engine RPM obtained on a scan tool which correlates with the concern. See Special Tools . Once these pieces of data are correctly plotted, the chart will point to the source of the vibration concern, which should confirm the results obtained through the following the Vibration Analysis diagnostic tables.
