MBS206 Posted April 24, 2022 Share Posted April 24, 2022 On 9/5/2021 at 1:16 PM, Roland@pcmtec said: It is similar in that it is a key challenge exchange, but that is about it. What is your goal? Depending on what it is I might be able to point you in the right direction time permitting. There is a lot of extra stuff to stop replay attacks, it also performs some kind of checksum on the responses. The actual alg looks similar in that it is some kind of XOR type of encryption. It looks like a multi part exchange that has a few more steps than the security unlock. We have disassembled the PCM to a high level, but none of the other modules. So to fully emulate it you'd need to do the BCM as well. But I can get some ideas about what the PCM side is doing from the work we have done to date. Hey Roland, Id hazard a guess the XOR check sum is likely a CRC-8 checksum. Nissan are known for it on critical messages too. Security type challenges ive seen documented (by the manufacturer) for other vehicles, is often taking the original value, inverting every bit. Add specific values to certain bytes, invert it all again, and then send it as the challenge response. All of it carries normally something like a CRC8 checksum too. This is all on the CANBUS not what the remotes are using. Quote Link to comment Share on other sites More sharing options...

jakka351 Posted May 25, 2022 Share Posted May 25, 2022 On 9/5/2021 at 1:52 PM, TheReaper said: Effectively I'm trying to work out if its possible to remove the PCM and still have the ACM/ICC work without whinging about the security code by emulating the PATS information or some other method. Hey this is a bit of misinformation - The ICC will work fine regardless of PCM or PATS - when a PCM is changed out and the AUDIO CODE ERROR comes up on the ICC its cos the battery was likely disconnected during the PCM swap, you just have to do level 1 security access 0x27 on the ACM and it will clear it. No pats or pcm relation. Quote Link to comment Share on other sites More sharing options...

jzxdan Posted November 22, 2023 Share Posted November 22, 2023 digging up an old thread, but want to make a little boost gauge for my territory. was wondering if any one had any ideas what canid relates to the boost pressure on a territory/bf?
