Opel CD40 USB

[shooting]

Code from cd40 usb is 2773.
The main cause of your broblem is different codes for radio and display.
You can try to change 4e4-4e7 from "97 38 49 69" to "97 3A 4E 69" (changing carpass from 2773 to 2503 ) and then try to deactivate.
Before deactivating check if the security time in display and radio not activated. Also check mid-speed canbus configuration, it must be the same

This will not work, CRC's need to be correct too

The best way is to have one unpaired device

I saw it and even compared dumps.
Which way you calculate crc? Can you explain it in PM?

This is the dump of my CD 40 USB. The code should be 2773.

I tried with choosing different unit, then go to Programming and Deactivate Theft Protection.

The OPCOM says deactivation is OK, but when I go to Measuring Blocks - theft protection stays at ID OK.

And when I try to activate theft protection with the car security code (2503) - programming failed as expected.

I will try again.

UPDATE:

After DOZENS of DOZENS of tries, somehow i managed to put this unit in Delivery state.

Alright, now I have to activate the theft protection. Here comes the DOZENS again.

After endless tries the CD 40 USB was successfully activated with my car's security code.

I'm completely sure that my chinese op-com or it's sofware (or both?) isn't working properly.

Thanks.

After security wait time was deactivated

I managed to put this unit in Delivery state.

Nope.

I was entering only the CORRECT key (2773) so no Security wait time was running!

Obvious my fake OP-COM interface is struggling with CD 40 USB devices, as long as there is no native support for it.

I wish you Merry Christmas and Happy New Year!

Your pairing would only work with 2503 (Car PIN) as you say this is your car pin,
impossible to work with 2773 (CD40) they don't work this way

Fact. But I was talking about deactivation of the theft protection.

This is extremely simple procedure - (1) deactivate with old code /2773/, (2) activate with car's code /2503/.

When you have the right tools, of course. Apparently I don't. But at the end of day everything works just fine.

Because you used my dump and paired using car pin

Nope, I did not. I already managed to complete the procedure and after that I saw the modified dump.

Don't get me wrong - I'm thankful for every help that I received in this forum. Cheers!
