5. View freeze frame
When an emission-related fault occurs, certain vehicle conditions are recorded
by the on-board computer. This information is referred to as freeze frame
data. Freeze Data is a snapshot of the operating conditions at the time of an
emission-related fault.
Note: if DTCs were erased, Freeze Data may not be stored in vehicle memory
depending on vehicle.
6. o
sensor test
2
OBD II regulations require that applicable vehicles monitor and test operation
of the oxygen (O
) sensors to identify problems that can affect fuel efficiency
2
and vehicle emissions. These tests are performed automatically when engine
operating conditions are within predefined limits. Results of these tests are
stored in the on-board computer's memory.
The O
Sensor Test function lets you retrieve and view O
2
results for the most recently completed tests from your vehicle's on-board
computer.
7. on-board monitor test
This function can be utilized to read the results of on-board diagnostic
monitoring tests for specific components/systems.
8. eVaP System Test
The EVAP test function lets you initiate a leak test for the vehicle's EVAP
system. This tool does not perform the leak test, but signals to vehicle's on-
board computer to initiate the test. The vehicle manufacturer determines the
criteria and method for stopping the test once it has been started. Before
using the system test function, refer to the vehicle's service repair manual to
determine the procedures necessary to stop the test.

retrieve a list of information (provided by the vehicle manufacturer) from the
vehicle's on-board computer. This information may include:
• VIn (Vehicle identification Number). It is applicable to model year 2000 and
newer OBD II-compliant vehicles.
• CId (Calibration ID). These IDs uniquely identify the software version(s) for
the vehicle's control module(s).
• CVn (Calibration Verification Number). CVNs are used to determine if
emission-related calibrations for the vehicle under test have been changed.
One or more CVNs may be returned by the vehicle's computer.
