Note:

If the steps are not carried out in the established order, the procedure for
programming will be completed.

Note:

The ignition keys must have the correct mechanical combination.

for the vehicle and they must be keys with PATS codes.

1. Insert the first programmed key into the lock cylinder

of ignition and turn the ignition switch from position II to the
position 0. (holding the power switch for 1 second, in the
position II )

2. Turn the power switch to position 0 and remove the first key from
ignition lock cylinder.

3. Within five seconds of turning the power switch to the

position 0, insert the second programmed key into the cylinder of
the ignition lock and turn the ignition switch to the position
0 to position II (keeping the power switch on for 1
second, in position II)

4. Turn the power switch to position 0 and remove the second key from the
ignition lock cylinder.

5. Within 10 seconds of turning on the power switch to the

Position 0, insert the unprogrammed ignition key (new key)
inside the ignition lock and turn the ignition switch of
from position 0 to position II (keeping the power switch on
for 1 second, in position II)

Note:

This procedure will delete all programmed contact keys from the
the vehicle's memory, and it will not start until it has two new keys

Note:

Two keys in PATS codes, with their correct mechanical combination, must
be available to carry out this procedure. One or both keys
they may be the originals for the client.

Note:

If additional keys are to be programmed, for more information consult

Key programming using two programmed keys in this section.
If the remaining keys are in the possession of the client and therefore are not present in
the vehicle, then tell the customer to consult the Vehicle Manual,
under the title 'Spare Key Programming Procedure'
('SecuriLock' in North America, 'Safeguard' in the United Kingdom and 'PATS')
for the rest of the markets), to obtain instructions for the
programming of said keys.

1. Turn the power switch from position 0 to position II.

2. Select 'PCM' from the scanner menu. Continue with 'Security Access'.

5. Insert the first key in code into the cylinder of the lock.
turn on and rotate the ignition switch to position II, for three
seconds.

Remove the first key in code from the ignition lock cylinder.

7. Insert the second key in code into the lock cylinder

 PASSIVE ANTI-THEFT SYSTEM (PATS)
also known as 'SecuriLock'
Description and operation of the system

There are several versions of Anti-Theft Systems used in vehicles.

Ford.
In this program, we will study the similarities and differences between some of
the most popular vehicles of Ford.

For the most part, all PATS systems operate in the same way.
When the module for the system is replaced, the new module must be
programmed to be able to recognize the ignition keys of that vehicle. If
new or additional keys are needed, the PATS module will need to be
reprogrammed to allow the use of new or replacement keys.

The main components for the operation of the system include for
Generally, the following components, which may vary by model of
vehicle

v Anti-Theft Indicator
v Hood switch
v Keyless entry remote transmitter
v Cover open lid switch
v Switches and actuators for closing and opening doors (LH and RH)
v Courtesy door entry (Driver)
v Relay to unlock door locks.
v Relay to lock door closing
v Relay for parking lamps
v Speaker relay
v Ceiling interior lamp (dome)
Operating Principles:

The PATS system, also known as 'SecuriLock', uses technology of

radio frequency identification to prevent theft, for example, of a
car entrance. The term 'passive' indicates that it does not require any
user activity.

The PATS system uses a specially coded ignition key.

Each coded key contains an installed electronic device.
permanently called a "transponder". Each "transponder" contains
a unique electronic identification code, which has many
combinations.

Each coded ignition key must be programmed within the PCM of the
vehicle, before being used to start the engine. There are
special diagnostic repair procedures already determined in
this manual, which must be carried out in case a new one is needed

The 'transceiver' module communicates with the coded ignition key.

This module is located behind the address column and contains a
antenna connected to a small electronic module. During each sequence
At vehicle startup, the 'transceiver' module reads the code of
identification of the encoded ignition key and sends the information to the
PCM.

The control functions are contained in the PCM. This module takes to

The PCM initiates the key interrogation sequence when the switch of

All elements that make up the PATS must function correctly.

before the engine is started. If any of them is not present
working well, the vehicle will not start.

The PATS uses a visual theft indicator. This indicator will demonstrate
for 3 seconds when the power switch is turned to the position
II or position III, under normal operation.
If there is a problem in the PATS, this indicator will flash quickly or
it will shine continuously when the power switch is changed to the
position II or to position III.
The PATS system will also flash the theft indicator every two.

The PATS will disable the vehicle's ignition if:

v The coded ignition key would be damaged.

v Unprogrammed key
v Key without code (key without electronics)
v Damaged wiring
v damaged transceiver
v Damaged PCM.

 Introduction

This course has been developed for students of Cise Electronics Training
Center - in Buenos Aires, Argentina - with the purpose of familiarizing them with the
Operating System of the EEC-5 engine from Ford Motor Company.
( EEC-5 = Electronic Engine Control, 5thGeneration )
EEC-5 = Electronic Engine Control, 5th Generation

The classes will be 50% theoretical and 50% practical (Hands-on experience).
They will take place over four days, in three-hour daily sessions.

The first two days will explain the input sensors and the actuators.
specific outputs of the EEC-5 system, as well as some tips
tools to make quick diagnoses with greater accuracy.
The PATS (Passive Anti-Theft System) will also be studied.
The last two days will be dedicated to implementing the new techniques and
information acquired throughout this course.

All questions you wish to ask will be gladly welcomed.

during the classes. The more questions asked, the better the System will be understood.
EEC-5 and to the PATS.
On the other hand, keep in mind that this is an overview of a
complex operating system and you will be able to inquire about procedures for
specific diagnoses and other particularities in the precious manual of
service.
