Hola Amigos,
Going to start documenting efforts on cracking the RCM on the Falcon. I haven't put alot of time into this yet but I have found some interesting bits - the module was manufactured by the same company (Siemens VDO) as the PCM, you will notice that both RCM and PCM cases are made of the same metal.
By modifying Fermec's PCM Flashread program and altering the CAN identifiers to be that of the RCM (0x737, 0x73F) and replacing the PCM seed key with that of the RCM (DIODE) I was able to get Fermec's program to read the RCM flash - so it looks like the RCM uses very similar processes to the PCM.
What little I have done is kept at https://github.com/jakka351/RCM, I will update this post as progress develops.
This is what peeked my curiosity, from the owners manual:
So we know that the RCM acts as both an Event Data Recorder and a Crash Data Recorder. Lots to discover.
TTFN

Re: FG Falcon Restraints Control Module & Crash Data
VERY interesting & great work with being able to modify the program to work on a completely different module!
Re: FG Falcon Restraints Control Module & Crash Data
Following with great interest, great work!!
According to chemistry, alcohol is a solution...
Re: FG Falcon Restraints Control Module & Crash Data
Updated the git readme and now have the RCM on the bench with the raspberry.
