This is a complementory article, so please read the base one first:
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!
