FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[stefancaromov]

Hi stefancaromov

What problem you have with the ELM?
Which vehicle would you like to read?
What controls you can not read?

Your pictures are very large but very blurry

I can recognize as a mistake on your ELM.

Especially not since you're describing a mistake.

For example on my own car i can read only selespeed and ecu ME 3.1
On my friend`s car i can read only engine - fiat stilo.
I cant read other systems as airbag, abs, electric wheel steering on stilo and so on ..
In our alfa romeo forum i read that on some elms, we need to broke one resistor called R14, but on my elm i didnt saw such a thing.
Better pic can be seen at

Hello
What is your vehicle?
What year is the Stilo?

To get to the airbag control you need a KKL interface and the red adapter.

And for ABS and steering certainly!
This comes on to the Year of the Stilo in

Because I suspect the vehicles have read from you yet no CAN bus
this I have to know what these are?

In your ELM interface can not I find a bridge resistance.
And think it also has no
You should check me once with a multimeter the OHM value between Pin 6 + 14 and write me this

One more question?

Can connect to the Body Comp to the Stilo. , CAN setup, make air conditioner?

I supose you cant understand me. So a friend of mine has a elm 327 bluettooth . At this device he broke some resistor called R14. So now he CAN read all valiues of his car and to other italian cars . Mine device is different, i want to read all also, but i cant. So the question was , how to make my elm to start read all devices in one italian car ? Ive had a cable and to read airbag i had to make connection between some pins. Here i cant do sush thing. I just want to make my elm read all in one car, not only engine and selespeed.


P.S. you mean if i am using wireless elm327 ( not with cable ) i wouldnt be able to make this change ?

[Alfaeddy]

Hello

Ok. understood.

But I have already written that you can not read all the controls with the ELM!

For some controls, a KKL interface mode is required.
Hence my question about your vehicle and year.!

And once again,
The bridge resistor is responsible for CAN bus protocols

Your friend's ok to use your ELM and then test whether the CAN bus
Controllers can read.

So, i understand i will not be able to read airbag and abs on my alfa selespeed. I did that with simple vag com cabel when i put together 3 and 9 pin if i remember correct.
If i buy some other model of elm 327 wireless would be able to make this change ? Or 100% i must buy elm 327 to USB for making this

[Alfaeddy]

All you need is a OBDkey Interface
but then of course the necessary adapters to

The OBDkey can read all necessary protocols.

I see, but still dont understand , how some people can read all when they remove this resistor on their devices? Is those devices are elm with cable - usb from the other side ?

[Alfaeddy]

Hi

This is wrong!
With an ELM you will never be able to read:

ABS Bosch 5.3
Airbag My 97
Bosch M 2.10.3
etc.

I dont know axactly what read and what not, but in our bulgarian forum ive read that. I saw many photos of those elms, but no on is like mine - wireless. The most of them are Bluetooth and this R14 is able to be seen and removed. On my elm what i must to remove, to have at least their capabilities ?
