I/M Readiness: I/M refers to Inspection and Maintenance and it indicates
whether or not the various emission-related systems on the vehicle are operating
properly. The purpose is to indicate which of the vehicle’s monitors have run and
completed their diagnostics and testing and which ones have not yet run and
completed testing and diagnostics of their designated sections of the vehicle’s
emissions system. The I/M Readiness can also be used to confirm that the repair
has been performed correctly and/or to check for Monitor Run Status.
Data Stream: This option gives you the data about the fuel system, calculated
load value, engine coolant temperature, short-term fuel trim, long-term fuel trim, and
engine RPM.
Freeze Time: When an emission-related fault occurs, certain vehicle
conditions are recorded by the onboard computer. This information is referred to as
Freeze frame data. This data is a snapshot of the operating conditions at the time of
an emission-related fault.
O2 Sensor Test: The results of the 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.
Onboard monitoring: This function can be utilized to read the results of
on-board diagnostic monitoring tests for specific components/systems. You can see
component ID, limit type, test value, minimum/maximum limit, and status.
Evap system: The Evap test allows you to initiate a leak test for the vehicle’s
Evap system. The scan tool does not perform the leak test but signals to the
vehicle’s onboard computer to initiate the test. Please refer to the vehicle’s service
repair manual first to determine the procedures necessary to stop the test.
