This interface is compatible with ELM 327 1.4! Should connect properly with all CAN modules.
All LEDs are blinking but i can't to connect to ECU !!!! or any other module !!!!
I have measured voltage between PIN7 and ground ,it is 12V and when i send command to ECU it dropped shortly and again come back to 12V.
Also i have measured voltage between CAN H and CAN L it was 0v and i can see voltage changing .
I have measured all voltage on the PCB and it seems ok
Few days ago everything worked well and i was enable to connect to every module including engine in my car.
Thanks in advance for any idea.

Hi Guys, I need your help and expertise, i bought this ELM327 V1.5a from eBay and it keeps coming up with time out errors, I have opened it up but it does not look like any of yours so please would you tell me which resistor to remove ( my car is a Fiat Bravo 2007 1.4 )

Because it is now so that many ELM no longer function even in Multiecuscan and this is due to the software on the Pic of the board
With many of the interface worked smoothly still 2 years ago
no longer running MES
This has nothing to do with ISO 15765, 9141, 14230, etc.
But the diagnostic software is no longer using the software on the interface (PIC) work together
Whether this is your problem, I can not say

Hallo Eddy!
Ich verstehe es, glaube ich, nicht 100%... Entschuldigung....
Kannst du bitte es auf Deutsch schreiben? Ich bin einfach interessiert, ob Diese ELM327 mit PIC18F2480 sicherlich gut sind?
Vielen Dank für deine Antwort...
Grüsse aus Slowenien

Hallo
Da ja fast alle ELM die am offenen Markt zu kaufen sind
chinesische Kopien sind.
Und auch die Chinesen diese immer weiter Entwickeln ist es leider dazu gekommen
das die meisten ELMs die seit knapp 2 Jahren angeboten werden nicht mehr mit Multiecuscan
oder auch AlfaOBD kompatibel sind.
Wenn es im Angebot heißt "Softwarer Version v2.1 " sind diese nicht mit Multiecuscan oder AlfaOBD kompatibel
Aber auch wenn Version v1.5 angegeben wird ist man nicht sicher das dieses ELM funktionieren kann
https://play.google.com/store/apps/deta ... fier&hl=de
Ich habe vor einiger Zeit eine APP gefunden ( ELM Indentifier)mit der kann man prüfen ob das Bluetooth oder Wifi ELM mit Multiecuscan
funktioniert.
Gruß Eddy

Based on all information I think, that is correct interface to made modification to work with Multiecuscan:

Hallo
Das sollte passen nur weiß ich bei diesem Angebot nicht ob ein Brückenwiderstand nicht die CAN Bus Protokolle behindert.
Aber bei diesem Angebot
http://www.ebay.de/itm/152303738760?_tr ... EBIDX%3AIT
bin ich sicher das es funktioniert.

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?

Figured it out - R04 with number 121 on top.
