    After playing with some of the algos and manually converting some of them to figure how it works, I found some inaccuracies in the manual.

    The 1`s complement and 2`s complement are switche
    The correct way to do it should be
    0x2A = Complement – if HH>LL use 1’s complement, else use 2’s complement

    This was checked for sure on algo 00, and verified on some other algos. It is known for sure that the formula of algo 00 is flip bits[or 1`s complement]

    oo algo
    2A [A9 >21]

    So 1`s complemet is flip bits or [FFFF-value]
    2`s complemets is flip bits and add 1, or [FFFF-value]+1


    Here are some valid combos for anybody that wants to manually convert the seed.

    05 [4F EE/ 53 A8
    06 [4F EE/ 42 C7
    07 [4F EE/ 15 29
    07 [53 4C/ 89 37
    10 [4F EE/ 2F 96
    0D [4F EE/ 5D 94
    0C [08 97/ E6 0E
    22 [4F EE/ CA F2
    28 [4F EE/ A4 FE
    36 [4F EE/ AB 5D
    12 [39 46/ 71 47

    Tom H can you run 4F EE seed in your app with all the algos and post the result for comparison. I can verify it and confirm that the calc are correct.

    I checked the first 20 algos and the were exact match. AFter that some random algos which also matched. At the end I checked some of the last ones, and they didn`t match. I further investigate I found that upto 5f they work fine. At 60 up to end there is a mismatch. Could be some typo in the script or we are missing something. I will calculated some of them manually to see if there is something else needed.

    Here are some verified from GM
    30 4fee /ca58
    40 4fee /83ac
    50 4fee /acc4
    5e 4fee /1d9e

    60 4fee /5703
    61 4fee /08ac
    70 4fee /9753
    7f 4fee /dcdd
    80 4fee /6b9d
    90 4fee /845a
    a0 4fee /375f

    I manually checked the algo after 60 and non of them match. So this table is valid upto 5f algo. After that it is garbish or wrong. Don`t bother trying to find an error. Just the algos after 60 don`t match at all.

    Hey guys,

    Are these algo's just for the PCM,

    Trying to find algo's for other modules like...Cluster, BCM, EBCM, HVAC...etccc

    Is there anyone that can push me in the right direction to finding these or working these out..

    Thanx

    I am trying to figure out the seed/key for GM Infotainment units (Radio). Any one working on this? Been studying it for a while. Looking for some help.

    I am interested in what you are doing & would help if I can.

    I believe that early cars (1997 and earlier: perhaps '98, '99) connect to various modules outside the PCM with serial / aldl type stream. Do later cars use class II? Do current cars use GM LAN?

    Each of these may use a different algo for security.

    I think that given the number of protocols, security algos and year2year changes, this may be a very difficult task.

    Some inside info from GM would make this easy...

    -Tom

    PS: is there a repository for GM documents?? I have a few that I stumbled over now and then. The best of these are often called "worldwide engineering standards". If you know of such a cache, I would love the URL.

    We have posted several GM docs in this thread.

    here is some examples of many radios with their seed and keys

    These have the 5 byte seed/key. I must say the new algo is complex as hell and not easy to calculate, if at all possible, without having some secret keys and a .dll from GM.
    The 2 byte seed/key algos are fully cracked and what you need is only the algo number and the algo table used.

    How did you get those combos. Have you tried offline programming of these systems or you need online connection for the unlock request.
    Do you have caches of the sps cache folder and the sps application folder to share?

    Yes I have to use ACDelco to get the key from the seed for all these radios. All IOBs, IORs, and IOUs all have seed and key. Which is needed in order to program them. I can do any programming I want to them after I get the key from ACDelco and I recorded all those Seed Keys from programming all those radios for customers. That's where I got that table from. I wish I could figure out the damn algorithm for these. New units don't have a seed or key cause the MEC is set to FF. To put security on you have to set the MEC to 0. If the MEC is not set to 0, you will not get LTE on the radio. So they have to have security for them to work correctly. You can activate security on the radios but you cannot take the security off. Once you set the MEC to 0 you can't reverse it and put it back to FF ever again. Wish there was a way somehow to Set the MEC to FF then that would take security off the radios. Maybe you could within a firmware update but haven't dove into that much.

    Thank you... this is a good thread for me. I have some documents specific to the '97 lt1 malf codes I will post.
