If the Scan Tool was able to link to the vehicle successfully a "Code
retrieval was successful..." message shows temporarily on the Scan
Tool's LCD display followed by any retrieved DTCs.
The Scan 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 Scan Tool.
If no Continuous Memory codes are
present in the vehicle's computer me-
mory, the Scan Tool will display a
"PASS" code (code 11 or 111).
Most Ford EEC-IV vehicle compu-
ters up to 1991 use a two-digit code
system. From 1991 to 1995 most
use a three digit code system.
The Scan Tool will display a code
only if codes are present in the
vehicle’s computer memory. If no
codes are present, a “No DTC’s are
presently stored in the vehicle’s
computer” message is displayed.
