CODE RETRIEVAL PROCEDURE
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 addi-
tional information.
9. 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 LCD
display) as visual aids to make it easier to determine
engine system conditions.
■ Green LED – Indicates that all
engine systems are “OK” and operat-
ing normally. All Monitors supported
by the vehicle have run and per-
formed their diagnostic testing, and
no trouble codes are present. A zero
will show on the CanOBD2&1 Scan
Tool’s display, and 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 CanOBD2&1 Scan Tool’s
display for confirmation. A Pending
code is confirmed by the presence of
a numeric code and the word PEND-
ING on the CanOBD2&1 Scan Tool’s
display.
B. MONITOR NOT RUN STATUS – If the
CanOBD2&1 Scan Tool’s display
shows a zero (indicating there are no
DTC’s present in the vehicle’s com-
puter 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 CanOBD2&1 Scan Tool’s 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.
