b) Test results reported by this service do not necessarily indicate a
faulty component or system. If test results indicate another failure
after additional driving, then a DTC is set to indicate a faulty
component or system and the MIL is illuminated.
Freeze Frame
In most cases the stored frame is the last DTC that occurred. Certain
DTCs, which have a greater impact on vehicle emission, have a higher
priority. In these cases, the top prioritized DTC is the one for which the
freeze frame records are retained. Freeze frame data includes a
snapshot of critical parameter values at the time the DTC is set.
Clear DTC
This option is used to clear all emission related diagnostic data, such as
DTCs, freeze frame data, and manufacturer specific enhanced data from
the vehicles ECM.
A confirmation screen displays when the clear codes option is selected
to prevent accidental loss of data. Select Yes on the confirmation screen
to continue or No to exit.
I/M Readiness
This function is used to check the readiness of the monitoring system. It is an
excellent function to use prior to having a vehicle inspected for compliance to
a state emissions program. Selecting I/M Readiness opens a submenu with
two choices:
Since DTCs Cleared displays the status of monitors since the last time
the DTCs are erased.
This Driving Cycle displays the status of monitors since the beginning
of the current drive cycle.
Live Data
This function displays the real time PID data from ECU. Displayed data
includes analog inputs and outputs, digital inputs and outputs, and system
status information broadcast on the vehicle data stream.
Live data can be displayed in various modes, see Live Data on page 29 for
detailed information.
