2.3 Oxygen Monitor Test
OBD2 regulations set by SAE require that relevant vehicles monitor and test the oxygen (02) sensors
to identify problems related to fuel efficiency and vehicle emissions. These tests are not on-demand
tests and they are done automatically when engine operating conditions are within specified limits.
These test results are saved in the on-board computer’s memory. The 02 Monitor Test function
allows retrieval and viewing of 02 sensor monitor test results for the most recently performed tests
from the vehicle's on-board computer. The 02 Monitor Test function is not supported by vehicles
which communicate using a controller area network (CAN), For 02 Monitor Test results of CAN-
equipped vehicles, see chapter On-Board Mon. Test.
2.4 On-Board Monitor Test
The On-Board Monitor Test is useful after servicing of after erasing a vehicle's control module
memory. The On-Board Monitor Test for non-CAN-equipped vehicles retrieves and displays test
results for emission-related power train components and systems that are not continuously
monitored. The On-Board Monitor Test for CAN-equipped vehicles retrieves and displays test results
for emission-related power train components and systems that are and are not continuously
monitored. Test and components IDs arc determined by the vehicle manufacturer.
2.5 Component Test
The Component Test function allows initialization 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.
2.6 Use UP/DOWN scroll button to select Component Test from Viewing Vehicle Information
