11. Refer to DISPLAY FUNCTIONS on page 3 for a description of
display elements.
In the case of long code definitions,
a small arrow is shown in the
upper/lower right-hand corner of the
Scan Tool display area to indicate
the presence of additional
information.
If a definition for the currently
displayed code is not available,
an advisory message shows.
12. Read and interpret Diagnostic Trouble Codes/system condition
using the display and the green, yellow and red LEDs.
The green, yellow and red LEDs are used (with the display) as
visual aids to make it easier to determine engine system
conditions.
 Green LED – Indicates that all
engine systems are “OK” and
operating normally. All monitors
supported by the vehicle have run
and performed their diagnostic
testing, and no trouble codes are
present. All Monitor icons will be
solid.
 Yellow LED – Indicates one of the
following conditions:
A. A PENDING CODE IS PRESENT –
If the yellow LED is illuminated, it
may indicate a Pending code is
present. Check the display for
confirmation. A Pending code is
confirmed by the presence of a
numeric code and the word
PENDING.
B. MONITOR NOT RUN STATUS – If
the display shows a zero (indicating
there are no DTC’s present in the
vehicle’s computer memory), but
the yellow LED is illuminated, it may
be an indication that some of the
Monitors supported by the vehicle
have not yet run and completed
their diagnostic testing. Check the
display for confirmation. All Monitor
icons that are blinking have not yet
run and completed their diagnostic
testing; all Monitor icons that are
solid have run and completed their
diagnostic testing.
