FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Alfaeddy]

Hello Galt

This older version is hard to get.
V1.3 or v1.4

Yani probably converted the software, which can now also v2.1 be used but I have not tested it yet.

This ELM is OK but which version is this I do not know

I took apart my diagnostic tool and it doesn't look at all like the other tools, this is how it looks, what resistors do i need to remove to make it work with my Alfa Romeo 147

Hi.
I had a 1.4 modified inferface but now it doesn't work.
So I bought a new Usb interface "ELM 327 V.1.5a"
It's the same as yours
A-U03AJ_M
but in version 1.5 2016-05-16
and it doesn't work.

(I think in this newest versions it's very difficult to switch wires and pins 6-1 and 14-9 ,
to obtain the yellow adapter (3) for MES...
but the 1st problem is.. that.. it doesnt work).

Hello

I have to write it again and again!
Most v1.5 ELM interfaces do not work with MES

Make a screen and you can see if this interface works with MES.

Because the interface test is also positive, even if a bridge resistor (120 Ohm) is installed.

Yes i ve seen, alfaeddy,
but i don't know which is the 1.5 version that works.
A seller told me should be ok with multiecuscan, so i bought a v.1.5, unfortunately the shipping were lost, so i bought another one (random, on ebay).
But no interface founded with Mes, with scanmaster, odbsomething, digimoto, ecc....
driver installed (original one, and cd's one),
interface with com7 founded, but there's an error in usb hardware settings... :/
Obviously now the interface it's open, so there is no warranty.
I need it urgently because i'm buiyng an used car.
I bought also a bluetooth and wifi version, but they didn't work with mes....
Anyway, I'll buy a new one ... again

Excuse for too many questions.
I found 7 different interfaces in my garage, no one that works ( and I need it

I have this older bluetooth interface (1.0, 1.5, I don't know),
it's very similar to the one that was posted by sende (24 Sep 2012).

I've modified the wires, but I don't remember in which way to put the white jack, so I can't use it.
I made a blue dot for reference but some days later, when I bought the switch, but I'm not sure.
I wouldn't burn all (car, elm, garage, home, etc).
Can someone help me?
No version is written on the circuit ("ObdII Scanner" Advanced Obd Scan Tool)
Should be a "victsing-mini-v1-5-elm327" but i'm not sure.
I hope it's possible to recognize the side of the plug, by the resistors, or something else.

(This is the last hope...).

Hello

Install this driver!
Some years ago, the drivers on the CD were the interface
Mostly unusable

Hi everyone... i will try to make this short as i can. I have a vechicle Mazda 626, year 1999, engine 2.0 100kw petrol. No obd II socket, just mazda 17 pin diagnostic socket ( I found out that it is like obd I(Older brother of obd II, or maybe im wrong)). And i bought a LM 327 1.5v bluetooth obd II scanner. Funny thing is i manage to connect some times and use difrent programs for like half a minute, and after that i can connect for few times straight.. Some times bluetooth connection not established, Some times it cant connect to my cars ecu. I Had luck with programs like Forscan, Scanmaster, Scantool.net, ScanXlpro, But it lasted short. 2 Mins max. I am using a laptop for all my atempts. Maybe i need tio desolder stuff ;DD , I have no idea what to do else... Here some pics from my elm327...
