Re: Siemens/Renault HELP, please!

Hi Bulent,

Believe me, I tried <0x81><0x7A><0xF1><0x03><CS>. Matter of fact, I
tried all <0x81><0x7A><0xF1><0x01-0x0F><CS>. The response I get
is:ServiceNotImplemented. It would have been great to have those
commands.

Now, if I do a slow init on 0x33, I can wake-up the ECU, but once I
try to send any command, again I get no response no matter if I try
KWP2000 or OBD-ii blocks.

Also, if I use functional addressing i.e. C0 +length i get No
response. Only works with 80+len.

I tried both KWP2000 blocks: <0x82><0x7A><0xF1><0x01><0xC1><CS>
and OBD-II blocks: <0x68><0x7A><0xF1><0x01><0xC1><CS>.

I get NO ANSWER. So, I'm stuck.

BTW: What is 0x61? Is it functional or physical addressing in OBD-ii?

And, apparently there is no length info in the OBD-ii block... so you
just receive all bytes until the last one matches the calculated CS?
Is this how it works?

Regards,
Stefan.B.
