Hi
As is well known, the elm 327 with EDF does not communicate if not ssi change the hw.
I have version 1.5, written on the box, but inside ? a 1.2
I tried to remove R4 and nothing
I put R4 and I removed R24 by placing a jumper between pin 6 of the pic and the component U1, but nothing.
Known that before I recognized a vagcom in the com port 4 and an elm327 in the com6. Now only the vagcom on com4.
any advice?
:confused:
the usb version or bluethoot?
and popi why? all of these changes,I usually I prepare it by removing a resistor to get it to communicate via adapters to the other ecu of the car as the body,aibag,abs, etc etc
also in the box on the metal, do it that way???Quote:

in 1.2 it takes only a resistance,both in the one box that in all of cable.
? the version with the box in aluminium grey. above c'? written v 1.5, but on the inside ? a v 1.2
not ? bluetoth but usb.
Remember what the resistance take?
If you want to use *********** with all of its functions ELM 1.2 is not good, you need to have from 1.3 up so you can do reset sevice using the n adapter?3.
I'm trying an ELM327-in-box. The only evidence that I have been able to do the tour since I have not under a vehicle Fiat or Alfa.
I tried to make a diagnosis (always-the-counter) with a ecu Magneti Marelli for Ducati and it works.
Then I tried to make a diagnosis (always at the desk) and a controller IAW59FHW303, using FiatEcusScan (vers. 3.4.2 and 3.6) but can not connect. I don't see the ECU.
In this moment I do not have a vehicle to do some test and I wanted to test it at the counter.
The version of the ELM 327 that I'm trying ? the one in the box with the writing on ELM 1.5 (I have read on the forum that the version may not be 1.5).
We accept tips for the test of the interface
With the free version all the functions are active; what tests can I do to figure out if ? however, to change by removing the resistance?
By default, the interface connects to only a few units: usually, ecu, engine, power steering, abs. To access other functions (can bus, drivers, weather, etc) ? need the appropriate adapter, different depending on the type of car. In this case, for?, not all interfaces work, and ? cos? need to remove the resistor. You have to try and see how it behaves.
Just yesterday I tried it on a Fiat Punto 1.200 cc 8-valve and it worked fine.
I have tested both USB model that BT both without modification.
Better cos?, from what I can see the interfaces that do not require change behave better in general. For the case, can you tell me how ? branded the internal circuit? Has a code?
Above I posted a picture of the schwda but not .there are acronyms
Ah ok. The photos can not display it. However, of the two interfaces that I own (both 1.4), we say "better" ? marked "CHX", and ? the same name with which it is detected. The other is seen as "the CAR". Externally for? are identical, so at the time of purchase ? also impossible to distinguish them...
It is, in fact, but ? also a matter of luck. Sometimes you buy two interfaces from the same seller, one works and the other doesn't.
Let's say that we are talking here about a few euros.
However, my ELM327 (usb) is displayed as EOBDII.
do not change resistors or other...
downloaded from the web and installed on the pc where you want to use the elm protocols uart - >usb...
And that's what I did (I have not changed resistors or other) but I have installed the drivers that I found on the cd, both for the bt version for the usb version.Quote:

before you dismantle and change resistance what cost? try sw??
Ah, thatÃs not a problem. Only I didn't know there were alternatives to the cases in which the interface does not connect. For?, also applies to bluetooth?
for bt I could not tell you....
for those usb acts as a all good....
to the days I try to update the elm with the sw 1.7....
let's see how it behaves...
so if I understand correctly you can? update the sw of the elm?
