CODE RETRIEVAL PROCEDURE
■ Red LED – Indicates there is a prob-
lem with one or more of the vehicle’s
systems. The red LED is also used to
indicate that DTC(s) are present (dis-
played on the CanOBD2&1 Scan
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 defini-
tions are the same on all OBD2
equipped vehicles. The CanOBD2&1
Scan Tool automatically displays the
code definitions for Generic DTC’s.
If the Generic definition for the
currently displayed code is not
available, an advisory message
shows on the CanOBD2&1
Scan Tool’s display.
■ DTC’s that start with “P1” and some
“P3” are Enhanced (Manufacturer spe-
cific) codes and their code definitions
vary with each vehicle manufacturer.
When an Enhanced (Manufacturer
specific) DTC is retrieved, the LCD dis-
play shows a list of vehicle manufactur-
ers. Use the UP
and DOWN
buttons, as necessary, to highlight the
appropriate manufacturer, then press the ENTER/LD
button to
display the correct code definition for your vehicle.
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/LD but-
ton for additional DTC information.
If the Manufacturer Specific
definition for the currently dis-
played code is not available, an
advisory message shows on
the CanOBD2&1 Scan Tool’s
display.
