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 diagnostics data such as, DTCs, freeze
frame data and manufacturer specific enhanced data from the vehicle’s 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.
4.5.2.2 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.
4.5.2.3 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 for detailed information.
4.5.2.4 On-Board Monitor
This option allows you to view the results of On-Board Monitor tests. The tests are useful
after servicing or after erasing a vehicle’s control module memory.
4.5.2.5 Component Test
This service enables bi-directional control of the ECM so that the diagnostics tool is able
to transmit control commands to operate the vehicle systems. This function is useful in
determining whether the ECM responds to a command well.
4.5.2.6 Vehicle Information
The option displays the vehicle identification number (VIN), the calibration identification,
and the calibration verification number (CVN), and other information of the test vehicle.
