Please excuse my English, it is a bit rusty.
Allready used the search function on the forum, can't find anything that provides me a solution.
I have a Alfa 156 1.9 JTD from the year (november) 2002.
When I try to connect with my OBDlink from Scantools.net (ELM327 to USB scanner) the following happens:
After clicking at least 5 times on "Connect" I get a connection and I can read and clear DTC's and perform all of the actuator tests.
BUT, when I click on "Parameters" and select, for example "Fuel pressure" the program exits to the mainscreen where I have to connect again.
I figured out that some values will work (made a screenshot), this is what works:
But the first option below "Injector class 5" the program exits again.
When the connection is lost I get the error: Timeout or port not correctly configured.
Allready tried changing the Baud rate in hardware settings and within FIAT ECU Scan with the following configurations:
PC @ 9600 - FIAT @ 9600
PC @ 83400 - FIAT @ 83400
PC @ 9600 - FIAT @ 83400
PC @ 83400 - FIAT @ 9600
All with latency at 1 (lowest possible) and I have no buffer settings for my virtual COM port.
Fat pressed = only one that "works", read connects after clicking at least 5 times and losing the connection after reading a value like fuel pressure.
Other tools (standard Scantool software) keeps the connection but there I am not able to read out Fault, perform actuator test etc. etc.
Here one more picture of my ECU data:
Thank you for your input!
Will defenitly buy a full version if this works!
