Using the Code Reader
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 Code Reader’s screen).
In this case, the Multifunction Indicator
(Check Engine) lamp on the vehicle’s
instrument panel will be illuminated.
On some vehicle models, the computer will store non-
emission related DTCs.These DTCs will not command the
MIL on since they are not emission related. If the Code
Reader retrieves one of these types of codes, the MIL will
not be commanded on, and the Yellow LED on the Code
Reader 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 Code Reader automatically dis-
plays the code definitions for Generic DTC’s.
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/FF 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/FF 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 Code Reader’s LCD dis-
play.
10. If more than one code was retrieved press the DTC SCROLL
button, as necessary, to display additional codes one at a time.
Whenever the Scroll function is used to view additional codes,
the Code Reader’s communication link with the vehicle’s com-
puter disconnects. To re-establish communication, press the
LINK button again.
