How to use PATS Module Initialization function (#p4962)

by FORScan » Sun M ay 31, 2015 1:42 am
This is a complementory article, so please read the base one first:
viewtopic.php?f=6&t=83 (http://forscan.org/forum/viewtopic.php?f=6&t=83)
PATS programming menu in FORScan has several functions, for some models the Module
Initialization option is available. This is quite important option so we have decided to
create a dedicated article to discuss it.
In many cases PATS system is distributed, it means more than one module is involved in
the protection. Module Initialization function is designed to synchronize (match) these
modules with each other. It should not be used during simple key programming (except
AU models). The inialization logic is model-specific, so it is always recommended to read
information FORScan provides before start of the procedure (same informaion is always
available using Help item in the PATS programming menu):

Another specific thing is that in some cases so-called Dual access to PATS may be
required instead of Single access. Obtaining outcode/incode is identical with Single
access, except that Dual type is displayed by FORScan and have to be specified in
Outcode/Incode calculator.

Let's review most common use cases:
1. Mondeo Mk3/Focus Mk1/Transit with Duratorq DI engines
In these models the Module Initialization function must be used if FIP (high pressure fuel
pump) and/or PCM module is replaced. Most common usage - initialize when new fuel
pump is installed. Duratorq TDCI engines of the same models have no Module
Initialization functions
If PCM module or both FIP + PCM are replaced, the following sequence of actions should
be performed:
i. Erase all keys (Single coded or timed access have to be obtained)

ii. Program at least 2 new keys
iii. Do module initalization
If only FIP module is replaced, then steps (i) and (ii) are not necessary and only step (iii)
have to be executed.
2. Focus Mk2/CMax
Module initalization function is used here when instrument cluster (HEC or IC) and/or
PCM module is replaced.
If HEC/IC or both HEC/IC + PCM are replaced, the following sequence of actions should
be performed:
i. Erase all keys (Single coded or timed access have to be obtained)

ii. Program at least 2 new keys
iii. Do module initalization (Dual coded access may be required)
If only PCM is replaced, the steps (i) and (ii) are not necessary, and only step (iii) have to
be executed.
3. Models for US market (1998-2010)
Module initialization logic here depends on the model, so follow FORScan instructions
and acknowledge the Help info as mentioned above. Also, timed access to PATS is used
for these models in majoirty of cases. Coded access is almost never used, so there is no
problem with outcode/incode.
4. Models for AU market (1999-2006)
These models have no dedicated functions for erase and program keys. Programming is
performed as a whole - keys are erased, then programmed. Module initialization is a part
of this process and called automatically. Module initialization can be called separately to
match BEM and PCM, for example if the match was lost for some reason or programming
procedure somehow failed before the initialization was completed. Coded access is also
not used here, similar to US market models.

I have tried several times to program pats! But to no avail. It will allow the erase and 1st
key but will not allow 2nd key to be programmed. Vehicle will not start without 2nd key.
Keys are OEM, so I know that is not the issue, please help!

If you experience any problems, please address to support (PM or email) and provide
internal FORScan logs for detailed problem analysis.
