I try to go over security access on me7.5 with kwp2000. My ecu is on bench (alone without cluster and other modules) and i use mc33290 to send and receive dates onkline at 10400. I used in short mode , not extended (f1 10): 1 slow init 2 start diagnoses session ( 81 and 86 respond ok, 85 is rejected) 3 Testerpresent 4 accesstimingparameters ( 0x83; 0x03; 0x00; 0x01; 0x00; 0x14;) 5 ecu identification All respond ok. After I tried 0x21 with 1,5,11,13,23,31 , i receive negative response 7f 10 11. Must make other timing parameters settings or put some special delays between commands? For bootmode if i try slowinit, ecu didn't respond. Some advice? Thanks
