CODE RETRIEVAL PROCEDURES - KOEO TEST
BE SURE to perform the added procedures in step 6, if
appropriate for your vehicle, BEFORE turning the
ignition ON.
- Press ENTER button to continue.
� If the Scan Tool cannot link to the
vehicle’s computer, the message
“Contact Technical Support” displays.
- Press The LD/M button to
return to the Ford OBD1 Menu.
- Turn the ignition off, and
disconnect the Scan Tool.
- Contact Technical Support for assistance.
9. If the Tool was able to link to the vehicle successfully a "Code
retrieval was successful..." message shows temporarily on the
Tool's LCD display followed by any retrieved DTCs.
� The Tool will display a code only if
codes are present in the vehicle's
computer memory.
� If no problems are found during the
KOEO Self-Test, the computer
sends a "PASS" code (code 11 or
111) to the Tool.
� If no Continuous Memory codes are
present in the vehicle's computer
memory, the Tool will display a
"PASS" code (code 11 or 111).
Most Ford EEC-IV vehicle
computers up to 1991 use a twodigit
code system. From 1991 to
1995 most use a three digit code
system.
10. If more than one code was retrieved, press DTC/FF button, as
necessary, to display additional codes one at a time.
In the case of long code definitions, a small arrow is shown in
the upper/lower right-hand corner of the code display area to
indicate the presence of additional information. Use the
and buttons, as necessary, to view the additional
information.
11. Disconnect the Tool from the vehicle and turn the ignition key OFF.
12. To prolong battery life, the Tool automatically shuts "Off" after
approximately three minutes of no button activity. The DTCs
retrieved will remain in the Tool's memory, and may be viewed at
any time. If the Tool's batteries are removed, or if the Tool is relinked
to a vehicle to retrieve codes, any prior codes in its memory
are automatically cleared.
