I am newbie to automotive cyber security and after becoming conversant with using canutils and SavvyCAN on ICS simulator , i wanted to try the same techniques on my cars (Volkswagen Vento -2011 model and Chevy Beat : 2012 model).
I followed the instructions on this web page (https://docs.macchina.cc/projects/use-m2-with-savvycan) exactly and everything worked like a charm (e.g. flashing M2 and replaying some CAN packets through it before connecting it to the car) . Used M2RET and SavvyCAN V199 on windows 10 Home edition.
However, i am unable to sniff/capture any CAN traffic when i connect the M2 to OBD on any of my two cars, despite the fact that SavvyCAN shows status as “connected”.
ELM327 OBD adapters work fine with their diagnostic apps on both cars though.
Can anyone please advise as to what i could be doing wrong here. Please do let me know if you need any more information that could help with resolving my query.
Many Thanks in advance of any help you could provide.
