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 36 for
detailed information.
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.
Component Test
This service enables bi-directional control of the ECM so that the diagnostic
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.
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.
