Retrieving Codes
KOER SELF TEST (EEC-IV SYSTEMS)
Chapter 4 36
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.
14. If any KOER Self Test Fault Codes were received:
■ Refer to page 46 for "Fault
Code Definitions for EEC-IV
Systems". Match the codes
retrieved with the codes
shown in the Fault Code
Definition list to determine
the fault.
■ Use the code definitions as a guide, and follow the
manufacturer's service procedures in the vehicle's
service repair manual to troubleshoot and repair faults.
■ All KOER codes that are received by the Code Reader
during the KOER Self Test represent problems that
are present now (at the time the test is performed).
The related vehicle problems that caused the codes to
be set must be repaired using the procedures
described in the vehicle's repair manual.
15. After all repairs have been completed, repeat the KOER
Self Test.
■ If a “pass code” (code 11 or 111) is received, it
indicates that the repairs were successful and all the
related systems are working properly.
■ If a “pass code” (code 11 or 111) is not received, the
repair was unsuccessful. Consult the vehicle's service
manual and recheck repair procedures.
