Data Stream Snapshot
Data stream Snapshot, is a current view of the onboard
vehicle sensors.
Mode 1 (Readiness Monitor)
Readiness Monitor Tests displays the results from the
continuous monitors available on the selected vehicle. There
are three states: ready, not ready, and not supported. If the
monitor is not ready, a drive cycle must be completed prior to
running this test. For more information regarding drive cycles,
refer to diagnostic functions Mode 1 readiness.
Freeze Frame
1. Select a frame.
Mode 2 displays recorded data in the form of a DS snapshot
by the vehicle’s computer when specic DTC are set and the
MIL is illuminated.
Mode 5 (Oxygen sensor tests)
Mode 5 views O2 sensor monitor test results.

Mode 5 views O2 sensor monitor test results. Mode 5
displays the average of the O2 sensor monitor test results
measured over a period of time. The parameters of this
measurement vary between manufacturers. It may be
necessary to run the vehicle for a period of time to allow the
O2 sensors to fully warm up and begin operating.
Note: Mode 5 is not supported on all vehicles.
