UDS Security Access Algorithm

Hello,

I am researching one ECU that I have in hand and I would like to know if someone has access to the security access implementation from JLR ECUs from mid 10s.

The seeds I am receiving from Level 03, 23, 25 are 4-byte length, for example:

can0 754 [8] 02 27 03 00 00 00 00 00
can0 75C [8] 05 67 03 C6 25 E3 00 00

I saw that there is a program called JLR_UDS:

But of course I cannot find this or other info online. If someone, knows anything regarding UDS in those systems and how to get elevated access please feel free to contact me, or comment in this thread. I would appreciate the help.

Best,
Thomas

The security software remote control system of the F type is what I hope you are considering. But I don’t know enough to even understand. What UDS is.
I am hoping somebody will hack Jaguar key to enable it to function like my Kia auto does. I.e. push the lock button and then the trunk open button and the car starts.
if JLR can do it, why can’t we?
