Chapter 9 Component Test (OBDII Only)
The Component Test function allows initiating 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 have 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.
To perform a component test:
1. Highlight the Component Test.
2. Wait a few seconds while the scan tool validates the PID MAP.
3. Select the test to be initiated from the Component Test menu.
4. A confirmation message shows if the test has been initiated by the vehicle.
