Hello folks,
After reading through some of the posts, I decided to join in with my bit, hoping this is helpful to someone.

On my board it was R2 and you can see the position in the photos. I removed the resistor, it was also marked 121 on top.

Fixed everything and I was able to use multiecuscan with no issues and do proxy alignment. The first post on this thread has a very helpful diagram which helped me identify the chip that has 8 connections, of which connections 6 and 7 lead to the resistor I needed to remove and then onwards to connector 6 and 14 in the OBD plug.

I hope this helps and thank you all for your advice and experience.

Have a nice day! There would be a problem that multiecuscan has a timeout on the kkl vag-com interface. I get this error message when setting port.

"VagCom / KKL

Testing latency with 200 bytes of data ...
There was a timeout during the operation. "
port setting timeout set to speed 9600. Multiecscan throws the same error. Interface chip FTDI ft232rl drivers are installed correctly. Please help! Auto for which it would need Fiat Brava 1.6 16v 1998 year elm 327 not read, program 3.6 registered. Thank you for your help!

Hi,

I am trying to connect to Fiat Bravo 2 (t-jet 150, 2008.) body computer.
I am using a cable from idiagnostics which I previously ordered for Fiat Stilo 1.4. (it worked fine)
When I connect the cable to Bravo Obd2 port, warning start to appear on the instrument cluster (ASR off, Hill holder unavailable....etc) and the car won’t start.
After the cable is disconnected, the car start with no trouble and no errors are shown.

Is the problem the interface (resistance, capacitance between pins), or are the wrong pins on the obd cable used?
I am attaching the photos of the cable circuit board.

Any help would be greatly appreciated.
