FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Dourados]

Good afternoon. Excuse my English.
I'm from brazil and comprehensive scanner, but it does not have many car functions.
Have:
Stilo 1.8 8v 2003
MultecuScan 3.6

Note: I removed resistor 121 but it still does not work at all. What should I do to make it work?

S130 MODERATOR POST UPDATE

For some reason the poster has not given any text to ask about his problem and only posted a link to 3 pictures.
I've checked the link out and they are safe/OK.

His problem is when connecting to a Stilo 1.8 8V he gets the error: "Empty PROXI File in Body Computer (BCM)!"

Hi!
i think that i have the same problemi with both my elm327 usb and bt interfaces: they connect to engine, ABS and steering but don't connect (with Adapter 3) to can.
If i understand right, i shoudl remove R04. Is it right? and if it's right, how can i remove it? I'm very noob in electronic!

in attachment the photo that i took to the bt device

regards

dears,

i have the elm327 but without Bluethoot,in the back PCB there is a missing FT323RL IC,what about it,what if we add that IC there will be any diffirence?

Thqnks

Hi I have problem with my ELM, I believe I need to remove some stuff from it. There is 213 pages in this thread but could someone help me which resistors/capacitors I need to remove in order to be able to use low CAN?

a question,there is missing IC U3 ithink is the ft323rl,what if we add that IC?there will be any diffirence?

Thanks

Hi friend
I have a problem with my ELM327, i try to connect it to my Fiat Ducato but appear one error when I connect, "ELM327->ECU Connection Failed!". The ELM pass all the connection test.

Can you help me to now what is the resistor that i need to remove?

This is my ELM327 adapter

This interface is compatible with ELM 327 1.4! Should connect properly with all CAN modules.

Gracias a retirar la resistencia indicada puedo acceder correctamente a los modulos CAN en un Fiat Punto 1.8 HGT del 2001, Funciona de maravillas con la demo Multiecuscan 4.0. Gracias

Hi all,

This post is extremely interesting and I would like to thank all the people who shared solutions for different models of ELM327 interfaces. I went through all the pages and didn't find anything related to my specific device (Bluetooth ELM 327). The closest circuit board I found was posted by lonerunner at the bottom of page 211. Alfaeddy answered that

His interface test shows that this ELM may not be compatible with Multiecuscan. It is often the case when the version v1.5 in ATZ and ATI is displayed the interface as not with MES functional. But There are also v1.5 interface which work problem-free.

I wonder if anything has changed since 7 months?
I did'nt find any ~120 Ohm resistor on my board. My car (Renault Megane 4) is not supported by MES, but this is the only forum post I found on the web dealing with fixing ELM327 clones. My device is working perfectly fine with software like Torque, but I would like to acces CAN bus from DDT4ALL or Pyren and it doesn't work.
Like other people on this post I tested with MES, and if I set the interface Type to ELM 327 Bluetooth, the test fails, but if I set the type to OBDKey 1.40 Bluetooth it successes. Please find below both tests results and also a test done with Pyren which shows 10 commands out of 95 tested that fail.
From what I read so far, I am pretty sure that I will have to buy another interface, but I thought it was worth asking on this post before doing so. And also it is not so easy to find in the large offer on the web a low cost interface that will work for sure.

Kind regards,

Hi guys, i have just bought this elm327 clone from aliexpress, obviously cannot works with my Alfa Romeo 147 1.6 TS 16v. There are some inscriptions on the card "A-L07AJ_M", "M160421" and "M160413". I read that it was enough to remove some resistance to make it work properly. Can someone help me?

I found solution for people with this board. looks like defective pcb design so stm32 chip is always stuck in programming mode. just short these 2 pads (solder thin wire) and it will work.

Hello guys. Can anyone help me with this interface? Fiat F-super interface. I search through the topic and i didn't find this model. I am trying to connect to ECU on a Alfa Romeo 156 1.9 Jtd 2003 , and i can't. I was successfully in connecting to ECU with the interface software but it's very limited (i can read only errors) and i would like to connect with multiecuscan. I know it is a piece of.....but i'm thinking that maybe someone has a fix for this. If anyone can help me i would appreciate it. Thanks.
Later edit: I am trying to upload pictures with the interface and it seems that i'm getting the message "sorry the board attachment quota has been reached"
Instead I've uploaded them here. Asking admins maybe they can help. Thanks
