I haved put a new steering whell with radio controls, clock spring with 16 pin for audio controls and conect a needed wires from clock spring to body computer using Elearn wiring diagrams...my radio has 2 wires CAN A, and CAN B from body.. - controls do not works..
Thanks and sorry for my english

Hi Romko

Sorry nobody has replied to this question yet.

The fiat Linea is a model I'm not familiar with as we do not have it here in the UK.

My first question is do other Linear models have as standard the steering wheel controls?

If yes then it is possible that the Body Computer in your model will support the retro fitted steering wheel.

Assuming that it does then a PROXI Alignment will be required.

MultiECUScan does support PROXI Alignment on the Fiat Linear however I can not say if when done that your retro fit steering wheel will function.

Hopefully someone else more experienced in retro fits and PROXI alignments will be able to offer more information.

s130,
thanks for the answer..
Yes , most Fiat Linea already have radio buttons ..
as far as I studied this question - I have the onboard computer similar to other models of Fiat and Alfa Romeo - just different firmware ..
 I was been at the official dealer and we tried to do the procedure Proxi - but it did not help, -during Proxy BSI interrogates only the assigned CAN branches in the original firmware.
on my BSI CAN Info: Steering Whell Controls are Not Active ...
Activate buttons dealer can not, because they do not have the software and permissions

Hi Romko

I'm afraid that based on your reply I'm not experienced enough nor have access to MultiECUScan internal Proxi code operations to be able to say if MES can do anything your official Fiat dealer can not do.

I guess Yani / MultiECUScan Support are the only definitive authorities on your request/question.

Yani, please, write in what we have a problem... Can the problem is in CAN Bus config of my Fiat? or is in radio SW?
Thanks ... and sorry for my english

[romko]

can any help me?
Yani, please write if the problem is in Body Comp I stop trying this

[romko]

Yani does not want to help me
if the problem is still in the Body-computer
I think it would be useful to implement this option in the new versions of Multiecuscan... - especially when there is а log of CAN Data both of cars

Here are some basic informations regarding BODY computer.
Data from BODY computer are stored in some chips and for reprogramming
those chips you need special programmer and software plus good experience...

Data on some chips can be programmed directly with ELM327 but only few of them.
All others can be only reprogrammed with special programmers.

So you need to copy data from BODY ECU which have other options you need to you BODY ECU but be careful not to damage security CODE for starting the car.
