FORD ENHANCED (OBD II) DIAGNOSTICS
This system applies to Ford vehicles manufactured from 1996 to
present. Some vehicles in 1994 and 1995 were equipped with the
EEC-V system. Refer to “Appendix A - Data Link Connectors".
Ford vehicles manufactured from 2000 to present automatically
use Global OBD II Diagnostics.
The first time the scan tool communicates with the vehicle, the communication
type is automatically detected, and is used until the scan tool is turned OFF or
another vehicle is diagnosed.
✓ If an Error Message displays, make sure the OBD II connector is
securely attached, and the ignition key is ON. Cycle the ignition key to OFF
for 10 seconds, then ON. This may be required to reset the computer. If
required, select YES to try again. If the problem still exists, refer to “Error
