Corsa D BCM

And there is no code here.

How to make XOR on all rows?

NEC
xx xx xx .. .. .. .. ......

93c86
xx xx xx .. .. .. .. .......

Thanks, but these guides are not up to date for the dumps I did.
I made two dumps, one on my BCM and the other on the backup BCM. I know the pin code on my BCM, but I don't know the other one. The information in NEC is almost the same, the main difference is in 93C86.
With the standard method I can't find the correct pin code of my BCM.

The photos were taken under Debian, and I compare the files with:

My BCM has no communication with SDM and IPC.


The pin code of my BCM is 9902. When I connect with Opcom to the car it accepts the pin code.
I tried different calculations, but never got 9902 to establish the backup BCM pincode.

With tech2 it is possible to recover BCM.

Unfortunately I don't have Tech2, but I have another dump that looks good.
I played around a bit to change his password (to 9902).
pincalc calculates it without problems and does not say that there is a problem. I'm thinking of writing it and seeing what happens.

You will lose keys.

Strange. If the reading is correct BCM donor pin code 4527. Ori BCM pin code FF. BCM reset?

Thanks.
Yes my BCM has been reset, but I wasn't sure if I was really resetting it with Opcom. Because there was no change in Low CAN BUS after reset.
I thought the pin code stays in the BCM after the reset. That fooled me.
I tried this combination, but only on a dump from my BCM and also got FF FF FF FF, but I was looking for 9902.

I hope to be able to test the backup BCM pin tomorrow, because I'm not home.
I guess pin code 4527 is correct. Because the information in many places is recorded this way:
2 1 4 3 6 5 8 7 ...

[Bllinda]

There is a button for that

The pin code is correct.
I had to read 93C86 in 16 bit mode.
I'm attaching a working dump.

Time lock BCM is adress : always after vin 8 and 16 position .... 0A no lock, 09 - 00:00:10 , 08 ... 07 ...

hello can someone help me in finding the bcm pin? opel? I am attaching file 93c86

[Bllinda]

But the farther away the less is willing to help. ....
