Using Diagnostic Equipment

Worldwide Diagnostic System:

SPECIAL TOOL(S)

NOTE:
^ This procedure is used when a customer needs to have an additional ignition key programmed into the vehicle without erasing stored key codes, but does not have two programmed ignition keys available. This procedure is also useful when attempting to determine if an ignition key is defective, as a new key can be installed without erasing ignition keys or without having two programmed ignition keys available.
^ Before programming, the new ignition key must have the correct mechanical cut for the ignition switch lock cylinder.
^ If eight ignition keys are already programmed, this procedure will not allow any further keys to be programmed without erasing all stored key codes first. The number of keys programmed into the system can be determined using the PID NUMKEYS.

1. Turn the ignition switch from the OFF position to the RUN position using the new, unprogrammed ignition key.
2. Enter diagnostic tool menu using the Ford Service Function (FSF) card and select PATS. Follow Security Access to obtain security access.
3. From the diagnostic tool menu, select IGNITION KEY CODE PROGRAM.
4. Turn the ignition switch to the OFF position and disconnect the diagnostic tool.
5. Start the engine with the new ignition key. The vehicle engine should start and run normally.
