Re: Motronic M1.8 Volvo 960 -91 information wanted.

Thanks to Sander I have now established contact with the ECU through
his KWP71Diag program. ECU ID:15h at 5bps, and then 4800bps
ID response is OK, Fault codes are probably different on the Volvo,
and ADC Channels returns something.

Is there a software or Visual Basic code that I can use to try other
commands? I think 02 for memory read as shown in the Fiat document
should work. If not I will have to reprogram the ECU to return memory
values in stead of fault codes or something.
