„ 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 Diagnostic
Tool’s display for confirmation. A
Pending code is confirmed by the
presence of a numeric code and the
word PENDING on the Diagnostic
Tool’s display.
B. MONITOR NOT RUN STATUS – If
the Diagnostic 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 Diagnostic 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.
„ Red LED – Indicates there is a
problem with one or more of the
vehicle’s systems. The red LED is
also used to indicate that DTC(s) are
present (displayed on the Diagnostic
Tool’s screen). In this case, the
Malfunction Indicator (Check Engine)
lamp on the vehicle’s instrument panel
will be illuminated.
„ DTC’s that start with “P0”, “P2” and
some “P3” are considered Generic
(Universal). All Generic DTC definitions are the same on all OBD2
equipped vehicles. The Diagnostic Tool automatically displays the
code definitions (if available) for Generic DTC’s.
„ DTC’s that start with “P1” and some
“P3” are Manufacturer specific codes
and their code definitions vary with
each vehicle manufacturer. When a
Manufacturer specific DTC is retrieved,
the LCD display shows a list of vehicle
manufacturers. Use the UP
and
DOWN buttons, as necessary, to
highlight the appropriate manufacturer, then press the ENTER
button to display the correct code definition for your vehicle. A
confirmation message shows on the LCD display.
