1997 Opel Vectra B

[autocentarvu]

Hi!
I have here Vectra B X20DTL with immo box problem. On engine ECU is P1502 No Immobiliser signal. I have put new (used) immo box and key and don't have P1502 any more but now I have Immobiliser wrong signal.
I made engine ECU virgin but op-com don't have solution for programming/resetting this type of ECU (Special functions and Programming buttons are grayed).
So if someone know how to reset this ECU or pair with new (used) immo box please help here. Immo box is immobiliser serie 1 and engine ECU is MSA 15 not EDC 15 (0 281 001 335).
I know that there is no immo off solution for this type of ECU (I have read that there is immo off solution but after 50 ignition cycles immo is back ON).
In attachment are dumps from engine ECU and Immo box.

Thanks in advance

Best regards

did you try swap dump from old immobox??

[autocentarvu]

No, I don't because before me customer was trying to repair this car by himself and he lose immo chip from key. I will give a try tomorrow amd try to programm used key that I have from new (used) immo box/car.

I think too, to replace CPU from old one to new one and in between read one with Xprog or other for HC05

Addr #57 is your PIN code two times in ASCII

with PIN you can easly teach new transponder in

@massiwe
I know how to find pin but thanks anyway. I will give a try today to swap mcu from one immo box to another and to program new (used key).
I will reply.

Here is you Immo Off try then report

[autocentarvu]

SOLVED by programming new immo box with old immo dump.

@electrodata
did you test this file @ car? I know that there is some immo off solution for this type of ecu but after 50 ignition cycles immo is on again :(

[autocentarvu]

I forget...

You can make immo off in this car by removing eeprom from engine ECU and disconnect immo box but after that RPM 3800 max.
On this forum there is immo off file but guy who post immo off solution said that after 50 ignition cycles immo is on again.
So if you wan't just to test if problem is in immo you can try EEPROM remove solution.

this is tested solution 100% work I used it before mate

[autocentarvu]

OK. Thank you mate but car is not in my workshop any more.

Cheers mate!

@electrodata

I'm looking to your immo off solution and there is something wrong.
MSA 15 have 24C02 which is 256kb eeprom memory
EDC 15 have 24C04 which is 512kb eeprom memory

File that you have send is 512kb so I assume that is for EDC15 NOT MSA15?
How did you test it in MSA 15 (you put 24C04 file in 24C02 memory)?

Hi mate Already update the post #6 please check the dump

It's my mistake when uploading the file

thanks

[autocentarvu]

OK. Thanks. First time will give a try.
