FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[jj747]

I meant the interface, you can figure out the version of the clone?

Hi jj747

Your pictures are very bad
I can not see any labels on the Bautteilen.

There is no writing on the pcb, likely to be a clone of a clone

Hi jj747

Of course, there are numbers and labels on the motherboard and the components!!!
I can see the yes, just unfortunately not recognize.
Looking for help here in the forum yes
The picture is really very bad.

Hi Guys, I need your help. I bought a cheap ELM V1.5 (10Eur) with BlueTooth. BT-Adapter connects successfully, but no connection to ECU. I read about issues with cheap ELM so I bought another one for 20Eur called Torque ELM. Exactly same problem. Bumped into this site, found the two resistors between pin 6-Earth and pin 14-earth and were (and read) 100Ohms. So now I came to a deadlock and can't figure out what's wrong. There was mentioned in some post a 4.7Ohm resistor (and who someone replaced and had no success )

Well here are my images maybe someone can kindly spot the culprit.

My car is Fiat Punto Mk2 [ZFA188]

Hello Stephen

First of all, very good pictures because you can see all the paths and numbers well.

But your connection error is not on the interface structure
because
1 The ECU your Punto is not read via CAN bus
2 Your interface has no bridge resistor
3 Torque has no problems with this bridge resistor

My guess.
1.You do not have a BT connection
2 You have installed the wrong driver.
3 The wrong Com port selected.


With this interface you should have no problems with Multiecuscan have.

Dear Eddy,

Thank you and sorry!

Thank you for replying so fast and probably accurate! Sorry because after my rush in registering and submitting my problem, I realized that the forum is specifically for Multiscan software (not a general ELM / OBD forum). I was directed here from a link to my post in FiatForum

The problem occurs on all Android Apps (my smartphone BlueTooth is fine and pairs the adapter successfully). I tried 8 apps and non gave me a successful ECU connection despite adapter is recognized. I am not fond of using MultiEcuScan on laptop in car, the apps on smartphone are (meant to be) really good and excellent portability. Bringing laptop in car is cumbersome. A multiEcuScan App would be awesome!

So if you or someone can still help me, I would appreciate, but if it violate regulations of the forum then I understand and apologies!

Hi Stephen

Since there is a AlfaOBD App

Hi! I'm trying to connect my Fiat Stilo with MultiECUScan and 327 interface but I'm only able to access the engine ECU. When performing a test, results show all is OK but accessing other parts results in connection error. Can this "fix" with removing the resistor apply here too? Here is the interface
