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.
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.
Vehicle Status
This item is used to check the current condition of the vehicle, including communication
protocols of OBD II modules, retrieved codes amount, status of the Malfunction Indicator
Light (MIL), and other additional information.
Exiting Diagnostics
The Diagnostics application remains open as long as there is an active communication
with the vehicle. You must exit the diagnostics operation to stop all communications with
the vehicle before closing the Diagnostics application.
