If the function is not supported by the vehicle, then the Scan
Tool does not display it.
✓Most Ford vehicles prior to 1996 use the EEC-IV system. Vehicles
with Mazda-sourced engines use the Mazda Electronic Control
System (MECS). Refer to “Appendix B - Data Link Connectors".
✓If the Scan Tool displays an Error Message, make sure the
adapter cable is securely attached and the ignition key is on. Cycle
the ignition key to off for 10 seconds, thenon. This may be required
because the Ford system allows only one Self-Test function to be
performed for each key on. Attempt the test selected again and if
the problem remains, refer to “Error Messages” on page 9-2.
