The I/M Readiness Monitor Status function also can be used (after repair of
a fault has been performed) to confirm that the repair has been performed
correctly, and/or to check for Monitor Run Status.
4. Data Stream
This option retrieves and displays live data and parameters from the vehicle's
ECU.
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. O2 sensor test
The results of O2 sensor test are not live values but instead the results of the
ECU's last O2 sensor test. For live O2 sensor readings, refer to any of the live
sensor screens such as Graph Screen.
Not all test values are applicable to all vehicles. Therefore, the list generated
will vary depending on vehicle. In addition, not all vehicles support the Oxygen
Sensors screen.
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.
The CRP12X Premium does not perform the leak test, but signals to vehicle's
on-board computer to initiate the test. Before using the system test function, refer
to the vehicle's service repair manual to determine the procedures necessary to
stop the test.
9. Vehicle Info
This option displays the vehicle information, such as VIN (Vehicle Identification
Number), CID (Calibration ID) and CVN (Calibration Verification Number).
