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.
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.
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.
Monitor 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.
