I have ELM327 with MultiECUScan Software and 2004 Fiat Stilo 1.6.

I can not connect to Body Computer or Proxy module.

I can connect to only engine module.

How is repair this ELM327 ?

Thanks a lot.

Hello

Unfortunately, the pictures are very poor can not be seen as extending the tracks and no number on the components to detect

I once marked a resistor of the CAN bus connection could be a problem.
Which number is in the red resistor (121)??

This, it could be

Unfortunately, I can not recognize the course of the tracks.
So I can not be sure

Hello

And the resistance of the bridge pin 6 +7 from the MCP chip is soldered?

Then remove it

Unfortunately, the pictures are not very good, and I can not track lanes

Hello

And where is the pin 7 of the MCP chip?

A higher resolution image would be helpful
I've already increased your image

Or try with removing this resistor
But the cautious can even re soldering

Hello

Therefore, it has been the correct resistor?

I am glad that I could help you :)
Good luck with your interface :)

dear Eddy,
bothering you again sorry Engineer, using this interface in pic 1 i only can acess the engine, how i can modify the interface to acess ecu and power steering?

Hello Stapy

to 1
Of course you can use this interface with Multiecuscan! Read the posts in this thread of Bluetooth

to 2
With Multiecuscan you can not immobilizer programming
That's what you need but also possibly not, if you use the transponder from the keys of the donor vehicle

Greetings Eddy
