FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Bumb]

Hello i bought elm 327 1.5a and i first i thought is the driver problems i didn't know unless i saw this thread.

I cant pass the last test on Multiecuscan v3.1.

U can see the problem is it in the second picture

I tried with different ports speeds and its fails in the first test.

Also when i connect to the car its says also that operation has timedout and check ports and cable...

Doi have to remove the resistor ?

Car is an alfa 159 1.9jtdm 150

Hello, I bought it on your recommendation and I am unsure with the functionality. We tried to use the interface on our 2008 Fiat Bravo 1.4 T-jet. If the interface is plugged in, all warning lights on the dashboard are ON and the engine coolant temperature gauge does not show - remains at start position. If it is not connected, everything is normal, lights go off after a few seconds and the temperature gauge moves to the corresponding position.

Is the interface ok? It is our first FIAT..

Thank you

I played with an old KL interface little bit and found out the AutoDia E327 interface has defective the FT-CAN (pins 2+10). It somehow cripples CAN bus of the car so ECUs store errors of the CAN. Supplier KWP2000 (ebay diadig) have not responded so far, so I cannot recommend purchasing it. So if you connect the interface to your car and all lights are on, do not go off, the interface is not good.

Hello

I would not say that an interface is synonymous mal mal !!
But I know some who bought this ELM and have no problems with it.

Otherwise one should buy the OBDkey interface or here the complete package
With the CANtie Interface !! At a completely different price


At pin 2 + 10 is not a bus or is your Fiat not from Europe ??
Since these pins are used for the SAE1850 protocol.


If your interface is broken you can return it.

Hello Eddy, thanks for response. The interface has connected pins 2 and 10, which according to http://marco.guardigli.it/2010/10/hacking-your-car.html provide FT-CAN (probably B-CAN?, also http://www.alfaobd.com/AlfaOBD_Android_Help.pdf mentions Bus). It confirms errors related to CANBUS if it is connected. You are right Interface is cheap, so it is easier to disconnect these pins inside.

Hello

I can unfortunately not follow your information?

Again, PIN 2 + 10 is not the B-Can
This is at Pin 1 + 9


Pin 2 + 10 is for another protocol (SAE 1850)

I have written this here
