Component Test
The Component Test initiates a leak test for the vehicle's EVAP system.
The scan tool itself does not perform the leak test, but commands the
vehicle's on-board computer to start the test. Different vehicle manufacturers
might use different criteria and methods for stopping the test once it has
been started. Before starting the Component Test, refer to the vehicle
service manual for instructions to stop the test.
1) Use the UP/DOWN scroll button to select Component Test from
Diagnostic Menu and press the OK button.
2) Wait for the scan tool to display the Component Test menu.

be displayed on the screen.

 Some vehicles do not allow scan tools to control vehicle systems
or components. If the vehicle under test does not support the EVAP
Leak Test, the message, “The select mode is not supported” will
display.
