Fiat Ducato 2.8 JTD Diagnosis: Software & Hardware

Hello,

I am trying to find information for a Fiat Ducato 2.8 JTD, model year 2004, type 244.
To extract information from the loaded dataset.
Unfortunately, the vehicle is not compatible with OBDII or EOBD standards. It's also not compatible with OBDI or anything else.

Initial attempts using ScanMasterELM v1.6 and the ElmCanII interface from CarCode-Müller successfully established communication with the control unit (ECU).
However, there were no usable sensor readings and also no dataset labels available.
According to ScanMaster, the protocol is ISO9141-2. This also corresponds to the pin assignments.
at the diagnostic connector.

Can anyone help?

Regards,
Gollum.
