EVA Software Cartridge

The EVA uses a Software Cartridge (J-38792-60), which provides various information to the EVA. The software cartridge provides the EVA with an additional feature which can be selected and utilized to assist in diagnosing vibration concerns.

This support-feature is available through the EVA Auto-Mode function. When selected, the EVA will prompt the user to select which one of 2 vehicle systems (vehicle speed or engine speed), is the suspected source of the vibration concern. Using the inputted vehicle data parameters along with the most dominate vibration frequency obtained, it will identify a suspected source of the vibration concern, such as first-order tire and wheel. This can be a useful feature when used in conjunction with the Vibration Analysis Diagnostic Tables, to confirm results obtained through the diagnostic process.
