Then why not flash full bdm from ori ecu to donor? Car should start

the owner sent the ecus to a friend who corrupted the files and then they bought 2 more ecus, this car has 2 ecus, so now we have 4 ecus and with all of them it starts only once, then you have to remove the battery for it to come back to start.

A long time ago I had that at Volvo ME7.0.
It was flash checksum problem.

Immo Off
Disabling Immobilizer...
Verifying checksums...
Block IMMO1 : Wrong but corrected (0xF29B)
Block IMMO2 : Wrong but corrected (0xF29B)
Corrected 2 checksums. You may save now.
IMMO is disabled.

How can it be a cks error in the flash when they are 2 ecus extracted from another car just like it was scrapped that only the immo in the eprom has been removed.
do you mean that the second hand ecus have the wrong cks when no one has programmed them before?
I think it's something a little strange

In addition, I also clone the data of the scrapped ones in the original ones because someone had already manipulated them and in this way have the original software, ktag is supposed to correct cks in writing, so when I wrote the soft it should have corrected the cks in case of being wrong .
only data has been inserted in the eproms to make immooff.

Anyway, I think I won't lose anything by trying what you say, maybe you're right.



but thanks for your help

I had problem cheksum maybe you have problem Immo Off
Best way is to update ecu with Odis enginering . Then all files will be o k.
Then male immo off and try to start

I dont know why dont more members help our friend here !
