FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[r_bobas]

Welcome. I have ELM 327 BT.

The device connects properly with the Fiat Panda 1.1. Read the engine. No connection to the ABS and airbag.

Tested with program Fiat Ecu Scan.

Please help me.

Thanks Eddy! will try that.

Please

And report here if it works now.

Greetings Eddy

It worked!!
but now I can't use my Engine ECU, it worked before.
I'll just use the VAG cable for that.

Hello r_bobas

What Panda you have exactly?
from the `03?


Then this is understandable

With this interface, you can read as you to a KKL interface requires no airbag.
Possibly with red adapter

And to be able to read the ABS you need the green adapter.

So close the interface and buy yourself the A1 adapter

And switchable for the airbag a KKL interface or with red adapter

Hello

This can not actually be
Because the resistance has something to do with the CAN bus protocol.
And since your ECU is read with KWP2000, this has no influence on it.

Maybe you have destroyed something else on the interface?

Colleagues have 327 Elm ver.1, 5 please help me what should I remove the resistor and if I should put capacitors. I freaked P04 but I do not know whether it is right.

Hello Rosenmvr

What control you want to read?
on which vehicle?

Your partially dissolved Resistor is the right one.
And a capacitor you do not need to solder a.

Hello, everybody.

I have same device as posted here: viewtopic.php?f=5&t=1493&start=1090#p13873

When connected to car OBDII connector (Fiat Stilo 1,9 MultiJet from year 2007), only red light is on, but MES can''t find my device (ELM327)!

Installed FTDI driver on XP SP3, port COM4, latency 1, MES 1.7 registered.



I'm not sure if wiring is ok?
