Using the Scan Tool
CODE RETRIEVAL PROCEDURE
26
The Scan Tool is capable of retrieving and storing up to 32
codes in memory, for immediate or later viewing.
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 on
the Scan Tool’s display.
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.
