Title: Ford C-Max 2015 BCMii secret Key (UDS SecurityAccess)
Post by: Flynn on January 24, 2021, 10:39:38 PM
Hello everyone,

While doing some test with my 2015 C-Max, I'm stuck with the security access service.

I have the seed/Key algorithm, based on this paper (http://illmatics.com/car_hacking.pdf) and many 5 bytes secrets extracted from the IDS Algdata.dll

If those secrets works on many ECU (RCM, ICM...), none of them are correct while trying a Security Access on the BCMii.

Any luck someone here know the 5 bytes secret for this ECU ?

Regards !
