Title: VW comfort/convenience CAN ECU Wakeup question Post by: zxcv on March 22, 2018, 10:33:58 AM Hi all,
i have a 3C0959433 (B6 comfort module) ECU on my table. With 12V attached, and a CAN Interface running on 100kbit for the comfort-can bus. I put a pseudo ECU (405) in the Comfort CAN Message-loop-Ring, resulting in a (in my oppinion) working message-ring-loop I see the following IDs every 100 to 400ms 40 delta ID data ... < cansniffer can0 # l=20 h=100 t=0 > 0.000000 343 00 80 00 ... unknown 0.000000 401 05 11 00 00 00 00 ...... THIS IS THE COMFORT ECU 0.000000 405 01 01 00 00 00 00 ...... THIS IS MY PSEUDO ECU 0.000000 591 00 01 8F 18 00 B4 02 00 ........ some lock status so the 401 ECU went from init to run - it signals that it wants to sleep (11) but seems to be online ? or am i wrong ? i also tried sending ignition messages but this does not change anything on all other requests i get no answer - i tired 200 - 14 C0 00 10 00 03 01 (for KWP channel setup with the ECU - it has 14 as id internally) but no luck - any hints what i am missing ?

I have no further details though. Title: Re: VW comfort/convenience CAN ECU Wakeup question Post by: zxcv on March 24, 2018, 04:30:41 PM i found a stupid typo in my code :(
now its working :-) Title: Re: VW comfort/convenience CAN ECU Wakeup question Post by: H2Deetoo on March 25, 2018, 11:04:20 PM What are you planning to achieve if I may ask?
From what I know not much can be done with these CCM modules. Rgs H2Deetoo Title: Re: VW comfort/convenience CAN ECU Wakeup question Post by: zxcv on March 26, 2018, 12:11:43 AM lets call it research for fun.
in this module is everything crypto related like RKE and IMMO, which is always intresting. the CAN approach is only to be able to talk to the module (which is working in the meanwhile). My actual topic is the securityAccess, where i request the seed but when i send the reply i have the problem i get somtimes strange (non standard ?)
