I'm trying to unlock a iso9141 segam ecu. The "xx xx" in the listing below is what I'm trying to figure out. This appears to be a response based on some transform of the "2A 6F" in the previous line that the sw must give to the ecu to unlock it.
sw - is my software
ecu - ecu response
The sequence is as follows:
sw - 82 D5 F5 27 85 F8
ecu - 84 F5 D5 67 85 2A 6F D3
sw - 84 D5 F5 27 86 xx xx 86
ecu - 82 F5 D5 67 86 39
sw - 82 D5 F5 A2 81 6F
ecu - 82 F5 D5 E2 81 AF
