Readiness Monitors
Use this menu item to check the readiness of the monitoring system. Monitors not
supported will display “not supported”. Scroll, if needed, to view the entire list of
monitors (Figure 9-3). 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 vehicle 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 the
distance driven while the MIL is on (if supported), can also be displayed.
Fast-Track Troubleshooter
Fast-Track
®
Troubleshooter is a database of experience-based repair strategies
and information, that has been compiled and validated by top-notch technicians.
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 test to display the serial data transmitted by the selected vehicle electronic
control module (ECM). The main body of the screen has two columns; the left-hand
column is a description of the parameter and the right-hand column is the
parameter value or state. Viewing options and operations are the same as the
Scanner function, see Scanner on page 25 for more information.

($02) Display Freeze Frame Data
Freeze frame data provides a “snapshot” of critical parameter values at the time a
DTC set.
This item is used to display freeze fame data for any stored emission related
diagnostic trouble codes (DTCs). In most cases the stored frame is the last DTC
that occurred. Certain DTCs, those that have a greater impact on vehicle
emissions, have a higher priority. In these cases, the highest priority DTC is the one
for which the freeze frame records are retained.
($03) Display Trouble Codes
This is used to display any stored emission related DTCs reported by the ECM. The
display is similar to the Scanner function code display (see Viewing and Saving
Codes on page 31 for details). The list does not include enhanced DTCs in this
mode.
