press the POWER/LINK
button to continue.
2. To read the display:
Refer to DISPLAY FUNCTIONS on page 9 for a description of
LCD display elements.
A visible icon indicates that the scan tool is being powered
through the vehicle’s DLC connector.
The upper right hand corner of the
display shows the number of the
code currently being displayed, the
total number of codes retrieved.
The Diagnostic Trouble Code (DTC)
and related code definition are
shown in the lower section of the
LCD display.
If the definition for the cur-
rently displayed code is not
available, an advisory mes-
sage shows on the scan
tool’s LCD display.
I/M MONITOR STATUS
icons are not displayed
when viewing OEM
enhanced DTCs.
In the case of long code definitions, or when viewing
Freeze Frame data, a small arrow is shown in the upper/
lower right-hand corner of the code display area to
indicate the presence of additional information. Use the
and buttons, as necessary, to view the additional
