9. If the CanOBD2&1 Scan Tool was able to link to the vehicle suc-
cessfully a "Code retrieval was successful..." message shows tem-
porarily on the CanOBD2&1 Scan Tool's display followed by any
retrieved DTCs.
■ The CanOBD2&1 Scan Tool will dis-
play 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 CanOBD2&1 Scan Tool.
■ If no Continuous Memory codes are
present in the vehicle's computer
memory, the CanOBD2&1 Scan Tool
will display a "PASS" code (code 11
or 111).
Most Ford EEC-IV vehicle com-
puters up to 1991 use a two-digit
code system. From 1991 to 1995
most use a three digit code system.
10. If more than one code was retrieved, press DTC SCROLL but-
ton, 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 CanOBD2&1 Scan Tool from the vehicle and turn
the ignition key OFF.
12. To prolong battery life, the CanOBD2&1 Scan Tool automatically
shuts "Off" after approximately three minutes of no button activity.
The DTCs retrieved will remain in the CanOBD2&1 Scan Tool's
memory, and may be viewed at any time. If the CanOBD2&1 Scan
Tool's batteries are removed, or if the CanOBD2&1 Scan Tool is re-
linked to a vehicle to retrieve codes, any prior codes in its memory
are automatically cleared.
■ See Viewing DTCs in the CanOBD2&1 Scan Tool's Memory
on page 14 to view DTCs stored in the CanOBD2&1 Scan Tool's
memory.
13. Follow the testing and repair procedures outlined in the vehicle's
service repair manual to correct "hard" DTCs. Codes should be
addressed and eliminated in the order they were received, erasing
(see Erasing DTC's on page 102) and retesting after each repair is
done to be sure the fault was eliminated.
