FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[stiloMjt]

Hi i have a fiat Stilo. i connect Fiatecuscan 3.6 with a ELM 327 1.3+ clone. all works fine, except for some functions that has strange behavior.

for Example steering wheel align : when start procedure and FES instruct to move steering on left after 1 sec without time to move procedure ends and FES return on main menu.

In this days i have some issue with alarm and i want to turn off. On FES Menu i have to input Electronic code and always receive "code not valid"(but i write original code from card).

Strange is that after three times i should have to wait 30 mins, but this is not true. i can try as often as i want.(always same error).

I don't understand if it is a FES issue or a ELM issue.

Thanjks for answer

Hello everyone!!

Could any body help with ELM 327 USB adapter ?

How i understand, for can reading i need to remove chip R04 or R14 ?

In picture below, there is elm 327 board, i bought ver 1.5, but on board sign is ver 1.0 ???

Will it work, or i need to buy another one ?

I have the same unit and it connects to the engine and gearbox modules but no others.

I am considering correcting it but was going to remove R2 as this is the only 121 ohm resistor on the board.

This is my interface.
Witch resistor must be removed?

Hi, have you found which resistor has to be removed?

Hello everyone!

Firstly thanks for your help because time ago I was able to modify an old cable elm327 with your help and advices.

I am trying to have another one but I have received an strange circuit board which I have not found over here. Does anyone know it and can help me with it?

Your help would be very appreciated



Thanks in advance for your time, help and knowledge.

Hello, i constatly receive the "can bus" error in multiecuscan, the test gives all ok back.
Scanmaster dectects the ECU, multiecuscan does not.

Hi
I just bought a similar interface (at least the main side of the board). Installed the CH304 driver on my old XP laptop.
MES connects to the car using this interface but does not show any live parameter values. Did you get yours going?
Thanks
