Retrieving Codes
KOEO TEST PROCEDURES (EEC-IV SYSTEMS)
Chapter 4 28
■ Code 10 is not a fault code. Code 10 is a “separation
code” used to separate the first group of codes (KOEO
Self Test Codes) from the Continuous Memory group
of codes.
■ Code 10 also serves as an indication to the user that
the vehicle's computer has completed the first part of
the KOEO Self Test, and that the next groups of codes
to be displayed are Continuous Memory codes.
11. Approximately nine seconds after
the Code Reader receives the
“separation code” (code 10), it
begins retrieving any Continuous
Memory codes that are present in
the vehicle's computer memory.
■ A small "C" is shown in the upper right-hand corner
of the display to indicate that the codes being
retrieved are Continuous Memory codes.
■ If no Continuous Memory codes are present in the
vehicle's computer memory, The code reader will
display a “pass code” (code 11 or 111).
12. After all the KOEO Self Test Codes and Continuous
Memory codes have been received by the Code Reader
(wait until the flashing square icon no longer appears on
the display for 30 consecutive seconds to ensure that all
the codes have been retrieved), press the ON/OFF button
to turn the Code Reader off, disconnect the Code Reader
from the vehicle's test connectors, and turn the ignition
off.
■ The codes retrieved are now stored in the Code
Reader's memory.
13. To view codes stored in the Code Reader's memory, press
the ON/OFF button to turn the Code Reader on, then
press and release the MEMORY button; the first stored
code will display. Continue pressing and releasing the
MEMORY button to scroll through the stored codes until
all the codes have been displayed.
NOTE: All retrieved codes will stay in the Code Reader's
memory and will only clear from the Code Reader's
memory if the Self Test procedure is performed again
(codes from a prior test will clear automatically when new
Self Test is performed) or if batteries are removed from the
Code Reader.
