[valentin.b]

Hi all,

I am hoping you can help me out I am trying to get a elm327 working on JT850 PWM and I am having no luck I am hoping someone here may be able to help me out I am attaching photos of the PCB.





Thanks,

Hello

Since I can not recruit more pictures in this forum,
I unfortunately can not provide more aid in cases
I can not say whether this is intentional?


But most interface has also been marked by me
Just need you to your appropriate interface from the previous pages looking out.

Furthermore, many interface produced currently incompatibilities with MES
Therefore, I have very often requires a screen from the interface test here
so you can see if the interface is at all compatible with MES.

Greeting Eddy


Edit:
@ Valentin your pictures are too small to see or to mark something.
Therefore, as I have already written this type has already been described in this thread and marked
Whether the software is compatible on-chip with MES, shows a screen from the Interface Test

I am new here.
I got elm 1,5 obd 2 usb version.
I have tried to connect trough MES with my 2002 stilo but no success.
There is no way. Every time i have message connection time out.
With other obd software i have connection and reading, but results are everything but.....

I think it is that resistor that need to be removed, but i don't know how to find it.
So please guys help me.

Hello
Your connection problem for Stilo has nothing to do with a bridge resistor.
Because on motor control you should also with a bridge resistor come

Which driver you have installed?
Mach times one screen from Interface Test
so I can see perhaps what is wrong

I let windows 7 find driver by itself.
I could not install this driver from http://www.ftdichip.com/Drivers/VCP.htm
and interface test doesn't find anything.
But scanmaster and obdAutoDoctor "see" it.

Hello

Then I can only say this is not your interface with MES Works is
Even with bridge resistance would connect to MotorECU be possible
Because the resistance concerns only the CAN bus protocol

Please
I see that your english is not so good.
You can send it in getman so i will translate it.
Tnx.

Hello
its right my englisch is bad


Dein Verbindungsfehler liegt nicht am Brückenwiderstand
Da dieser Widerstand nur im CAN Bus Protokoll Probleme macht.

Aber da deine Motorsteuerung im KWP2000 Protokoll gelesen wird sollte dein Interface
auch ohne Modifiktation funktionieren.
Ansonsten funktioniert entweder dein Interface nicht
oder du hast den falschen Treiber installiert.

I have the same ELM (I bought another one but the PCB is the same)
Removing the R2 Resistor (the one closest the middle of OBD connector) I succesfully tested the ELM with easyOBD free, without installing any other USB driver.
I can read rpm, temps and so on but with MES the problem persists (with or without adapter).
Can't find the interface with the MES "search" feature and timeout adding it manually.
I'll retry with ScanMaster software to verify if it could be a settings issue or my ELM is finally incompatible with MES.
