Title: Re: Trying to emulate an ECU - packet not understood [SOLVED, was Display, DDP] Post by: zxcv on April 01, 2018, 10:20:04 AM 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 ?

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 or with google translate: https://translate.google.com/translate?hl=de&sl=ru&tl=en&u=http%3A%2F%2Fpccar.ru%2Fshowthread.php%3Ft%3D24102 Regards Title: Re: Trying to emulate an ECU - packet not understood [SOLVED, was Display, DDP] Post by: google85 on June 01, 2018, 12:12:12 PM man, you're awesome, thx for the clarifications and the link!!
Did you found something else about these MFA+ protocols, any other hidden commands? |
