Readiness Monitors
Use this menu item to check the status of the monitored system. If a monitored system is not
supported, it is not displayed. Scroll, if needed, to view the entire list of monitors. Selecting
Readiness Monitors opens a submenu with two choices:
•
Monitors Complete Since DTC Cleared
—displays the results of all monitor tests that have
run since the last time the electronic control module (ECM) memory was cleared.
•
Monitors Complete This Cycle
—displays only the results of monitor tests that ran during the
current drive cycle, they reset when the ignition is switched off.
MIL Status
This item is used to check the current condition of the malfunction indicator lamp (MIL). Additional
information, such as which ECM commanded the MIL on and also the distance traveled while the
MIL is on (if supported), can also be displayed. It is also possible to print the MIL Status.
Fast-Track Troubleshooter
Fast-Track® Troubleshooter is a database of experience-based information of validated
real-world repair strategies that have been compiled by top-notch technicians since 1988. The
Troubleshooter system simplifies the diagnosis process, as it contains information on virtually all
common diagnostic trouble code (DTC) problems and driveability symptoms for most vehicles
covered by the vehicle communication software.
($01) Display Current Data
Use this item to display the current emission related data from the selected electronic control
module (ECM) of the vehicle. Displayed data includes analog inputs and outputs, digital inputs and
outputs, and system status information broadcast on the vehicle data stream. OBD Direct data
displays similar to Scanner data, refer to
on page 49 for details.
($02) Display Freeze Frame Data
This item is used to display freeze frame data for any stored emission related diagnostic trouble
codes (DTC). In most cases the stored frame is the last DTC that occurred. Certain DTCs, those
that have a greater impact on vehicle emission, have a higher priority. In these cases, the highest
priority 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 set.
($03) Display Trouble Codes
This option displays any stored emission related DTCs reported by the various ECMs. The OBD
Direct code report is similar to a Scanner module code report, and includes the
