Hello,
I’m having problem to find a solution to my issue, I make a log and receive 2 bytes as SEED, and 4 bytes are the KEY to send to the ECU in my communication, I’ll be clearer.
I make the communication with the ECU, then I send a command to request the SEED, the ECU sends to me 2 bytes, then I have to send the key, which are 4 bytes are right key. What I need is the algorithm to calculate the KEY to send, since I have the SEED and the Result.
Received SEED KEY Sent
92 90 <<<<<<< if I receive this, how I get this >>>>>> 02 2A 7C 90
BC BB .................................................. ..................... 31 A0 21 1F
73 90 .................................................. ..................... 17 A7 B7 60
19 CA .................................................. ..................... 0B B9 53 3A
8A 53 .................................................. ..................... 01 4B BE F4
(OS. This SEED’s and KEY’s are valid).
I hope someone could help me to solve this problem; I’m took several days to analyze this and haven’t any result.
Regards.
