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. A zero will show on the
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 Scan Tool’s
display for confirmation. A Pending
code is confirmed by the presence
of a numeric code and the word
PENDING on the Scan Tool’s
display.
B. MONITOR NOT RUN STATUS – If
the Scan Tool’s 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 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.
