Hi all.

when i power up my (standalone) vw immo/convenience ECU, the ECU tries to open a channel
to another ECU on the (convenience) CANbus.
I emulated the TP2.0 so far and chose an ID of 0x4D0 for my pseudo ECU.

So this is what happens:

<- [0002638733] ID: 221 - 48 C0 00 10 28 03 10 (green is the short id of the unknown ECU)
[EEMU] got channel setup from 0x221 (pink is the 0x200 + 0x21 ID of the convenience ECU)
-> [0355465687] ID: 248 - 21 D0 28 03 D0 04 10
[EEMU] sent emu D0 response from emulated 0x248
<- [0002638743] ID: 4D0 - A0 04 59 FF 32 FF
[EEMU] got channel com params to my can ID - blocksize=0x4, timout=25ms, min. consecutive message time=50us
-> [0355465687] ID: 328 - A1 04 59 FF 32 FF
[EEMU] sent A1 parameter response - blocksize=0x4, timout=25ms, min. consecutive message time=50us
<- [0002638763] ID: 4D0 - 10 00 21 00 FF
[EEMU] got a single frame TP2.0 packet
-> [0355465718] ID: 328 - B1

so now my question - anybody any clue what this red packet is ? its not KWP2000, neither KW1281
any idea ?

Kind ragards

i found it on some russian forum  Smiley

0x48 its the Display ECU, and the protocol seems to be called DDP (Display Data Protocol).

its directly on TP2.0 and communicates with the display.

For reference: http://pccar.ru/showthread.php?t=24102

Did you found something else about these MFA+ protocols, any other hidden commands?
