Hello Pumpingiron91

The bridge resistance I have highlighted in red frame

Who is responsible for problems with the CAN bus protocol
But even for CAN bus problems for other read error, this is not the problem

Hi Luca Rossi
Here also again, your board has no bridge resistor
I would ask at your first post already are
Which vehicle you would like to read?
Year of construction?
Control?
Your interface has no errors I can see

Oohh, and what's my job with this? Change it or only remove? If i remove than connect the 2 sides of each other? Last question, when i use the MES i can do everything only in the ECU, in other modules all time writes for me: elm connection failed.... if its important its a 2003 Stilo 1.2.

Hi Luca Rossi
A ELM327 v2.1 does not work with Multiecuscan
since there is no possibility
So I asked if there is a v1.5 or v2.1 a
You need to other ELM Interface

Hi eddy this is azeem , I have the same problem as lucarossi with my elm327 v2.1 Bluetooth with multiscan and even all android obd apps it says unable to connect to ecu .
My car is fiat palio stile (facelifted) 1.6 16 v (Indian version) with 3 pin to obd converter ..
Any help ? What obd device I need and any chance getting elm327 Bluetooth to work on this car ?
Cheers

I believe that this vehicle use VAG/KKL. I also could not connect the MES with a Palio 1.5 1996

Hello everyone, I wanted to change the chip MCP2515 with a version V1.4 type the PIC18F2580, but this chip is not found in 18 feet to be welded, so I ask you, there is a chip in 18-pin compatible with version V1.4

Maybe not so simple just change the chipset, which can use a different circuit. Why do not you just buy a version 1.5 ???

Hello!
I have a ELM327 USB with PCB like in photo.

It connect only to engine ECU, not to other ECU.

I see my interface is similiar to Tasmo's one (viewtopic.php?f=5&t=1493&start=1680),
but it has more component on the right (in my photo) that weren't on Tasmo's PCB.

How I can solve?

Thanks.
