„ 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 Multifunction Indicator
(Check Engine) lamp on the
vehicle’s instrument panel will be
illuminated.
„ Flashing Red and Yellow LEDs – Indicates that a "permanent"
code has been set, and one or more of the vehicle’s monitors
has failed its diagnostic testing. A "permanent" DTC can be
cleared only by the vehicle's computer following successful
completion of the monitor that caused the fault to set.
„ 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 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/FF
button to display the correct code definition for your vehicle. A
confirmation message shows on the LCD display.
- If the correct manufacturer is
shown, press the ENTER/FF
button to continue.
- If the correct manufacturer is not
shown, press the DTC SCROLL
button to return to the list of
vehicle manufacturers.
If the manufacturer for your vehicle is not listed, use the
UP
and DOWN buttons, as necessary, to select
Other manufacturer and press the ENTER/FF button
for additional DTC information.
If the Manufacturer Specific
definition for the currently dis-
played code is not available, an
advisory message shows on the
