CODE RETRIEVAL PROCEDURE

If
Error
is shown on the Code
Reader’s LCD display, it indicates
there is a communication problem.
This means that the Code Reader is
unable to communicate with the
vehicle's computer. Do the following:
- Turn the ignition key off, wait 5
seconds and turn the key back on
to reset the computer.
- Make sure your vehicle is OBD2 compliant.

Read and interpret the Diagnostic Trouble Codes using the LCD
display and the green, yellow and red LEDs.
The green, yellow and red LEDs are used (with the LCD
display) as visual aids to make it easier for the user to
determine engine system conditions.
Green LED
- Indicates that all
engine systems are "OK" and
running normally. All monitors on the
vehicle are active and are performing
their diagnostic testing, and no
trouble codes are present. A zero will
show on the Code Reader’s LCD
display for further confirmation.
Yellow LED
- Indicates one of the
following conditions:
PENDING CODE PRESENT
- If the
yellow LED is lit, it may indicate the
existence of a pending code. Check
the Code Reader’s LCD display for
confirmation. A pending code is
confirmed by the presence of a
numeric code and the word PENDING
on the Code Reader’s LCD display. If
no pending code is shown, the yellow
LED indicates Monitor Status (see the
following).
MONITOR STATUS
- If the Code
Reader’s LCD display shows a zero
(indicating there are no DTCs present
in the vehicle's computer), but the
yellow LED is lit, it indicates a
"Monitor Has Not Run" status. This
means that some of the Monitors on
the vehicle have not yet finished their
diagnostic self-testing. This condition
is confirmed by one or more
blinking
Monitor icons on the LCD display. A
blinking
Monitor icon means the Monitor has not yet run and
finished its diagnostic self-testing. All Monitor icons that are
solid
have completed their diagnostic self-testing.
