Technical BCM questions

[grun500]

I have tried to find more information regarding the body control modules, but I'm constantly fighting the search function.

As I understood, the IMMO is within the BCM module. If you have a bad BCM and want to replace it, you have to go to dealership?
Or are there tools to read the IMMO dump from the BCM and copy/clone the info to other simular BCM module?

I have done this on other cars (VW Passat) and replaced the module that holds the IMMO
Does any one have experiance with this?
Is it known what eeProm the BCM uses for IMMO?

Since no one reacted, where can I find wiring diagrams and pinout scematics of BCM and parts connected directly to the BCM.
Who can help me with that?

...but I'm constantly fighting the search function.

I understand.
I've not had any experience with BCM's, only my own vehicles ECM.
Any particular part numbers or vehicle specs?
I find this very interesting, I'll help search.

as I understand, IMMO is on the BCM. So I would like to buy a identical one to see what type of eeprom is used.
Then clone it. I also want to see what the differences are between the current models with uconnect on BCM and the ones with blue and me

I agree.

As I did with my ECM ECU.

Urgh , "uconnect" now you're boring me.

Are BCM's vehicle specific, or generic?

 

[grun500]

I would guess BCM´s are kind of generic and via programming specific

Ok, I'll find out, having a look now, will post anything I think you may find useful.

 

[grun500]

do you know where I can find partnumber lists and wiringschematics?

 

[GettinBetter]

Not yet, searching for stuff.

 

[grun500]

I did lots of modifications in VAG cars and basics look to me the same. Im going to dig deeper

 

[GettinBetter]

What software have you got for reading the pins on a BCM?

 

[grun500]

I use for diagnostic MES and depending what kind of eeprom is on the board you will need a clamp tool to read the eeprom.

 

[GettinBetter]

I used MPPS to read and download my bin file from my ECM, and WinOLS to explore it.
But the BCM seems to require other such as VCX Nano. Stilll looking.
But need to check vehicle support list.
ah, only works on GM & Opel

 

[GettinBetter]

Are you familiar with reprogramming keys?

Someone recently posted the attached.... sorry can't recall who

 

[GettinBetter]

Well, there is stuff out there, just not for Fiats, unless you want to pay pro kit prices. There are lots of services out there too.
There is no easy way but to spend time researching.
I'd quite like to get a spare for my car to explore.
