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 8-3
). 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.
Troubleshooter
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 13
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
Codes - View / Save on
page 19
for details). The list does not include enhanced DTCs in this mode.
($04) Clear Emissions Related Data
This item is used to clear all emission related diagnostic data, such as DTCs, freeze
frame data, and test results, from the memory of the selected ECM.
