DISPLAY
The Digital Wrench Data Display can be configured to

The E-VES data items will not show any information or
populate current (active) diagnostic trouble codes
(DTCs) unless one of the following conditions is met:
• Engine is running
• Battery voltage supplied to the ECU PWR test and
Critical PWR test connectors.
The data display image shows the four data items for the
E-VES system. Digital Wrench is connected to the
snowmobile with the engine off.
