Subject: [opendiag] Problem after wake-up of ECU
 
Hi,

I'm trying to communicate with Renault Megane 1.9dci from 2001
(Siemens Sirius 32) with Jeff's interface but I can't get lot of
stuff actually and need some help.
Here is what I'm doing:

1. Setting-up COM port at 10400bps 8/0/N/1 no handshaking
2. Wake-up ECU with a slow init on both K and L line using RTS and
Break with a timer
3. ECU answers <0x55><0xE9><0x8F>. Apparently it's KWP2000 compliant
4. Wait 500ms
5. Send <0x81><0x7A><0xF1><0x81><0x6D> with 10ms interbyte but don't
get any answer from ECU

I tried sending <0xC1><0x7A><0xF1><0x81><0xAD>,
<0x81><0x33><0xF1><0x81><0x26> and <0xC1><0x33><0xF1><0x81><0x66>
too but didn't get answer too.
I think I'm missing something but I really don't see what.

I'm also looking for informations about fast init if someone can
help.
Thanks in advance!

Frederic Martin
