I'm trying to use my smartphone to move my cars windows up and down. I recorded the CAN traffic two times by using AT MA. First time I just turned the ignition on. The second time I pushed the buttons for the electric windows. I guess the PIDs for the window are the ones which didn’t occur in my first log file… Now I want to try this by sending the bytes back but how can this be done with the ELM 327? This is a message I received:
400 23 00 00 00 00 00 00 00
I already tried to set the header by doing:
AT SH 400
And then I wrote the remaining bytes to the stream:
23 00 00 00 00 00 00 00
But this seems not to be the cheat…
Cheers, Stefan
