    Default Opel Meriva B immo ECU adaptation

    Hello,

    I have an Opel Meriva B 1.7 with an AC DELCO E87 ECU I can't adapt new ECU to the car, I have reseted the pin many times and written new pin.

    • The ecu have the same pin as the BCM and instrument cluster
    • All vins are programmed and are similar
    • 2 keys are programmed successfully
    • I always respect security time wait about 10 minutes
    • Pin is valid


    But I always have the immo light on and the following dtcs in the ECU:
    • P0513 Immobilizer Key Incorrect
    • P0633 Immobilizer Kew Not Programmed


    I don't have immo related dtcs in other control units.

    I am working with OP-COM 2018 and AVDI official.
    I also have GDS2 and TECH2 but there isn't any ECU immo related function on them.
    I would very much appreciate if anyone would help me.

    Thanks

    Did you try to programme with Avdi? Seems like the issue is on the immo box. I had same problem actually I swaped ecu because was damaged with a donor programming procedure went fine but light was still on and car will start for a second and shut off my issue was the cluster I did reprogrammed cluster itself and problem solved

    It starts for 2 seconds because of the immo system is enabled. Then issue must be on the donor ecu. If the car had no immo issues before is hard to have now. The question is why they open the old ecu

    I do program a lot of opel and I do use same combination avdi and opcom and I have been in a lot of situations with immo,and opel immo is simple not to complicated if you don't know why they open original ecu you must find out start from there and then we go step by step

    I have 3 ecus, it is the same with all of them, he tell me that the ECU was dead they try to solder inside, they removed the processor ...
    it’s not usable anymore.
    I know that Opel isn’t that complicated.
    Can it be ABS related issue ?

    There is no immo on the abs only ecu cluster immobox and body. Probably the car had same issue before and they open ecu for no reason,so ecu will do no difference. How's your live data will it read keys when you crank?

    Live Immo data look good, I have to check when I crank. I read that for ACDelco E87 a Russian guy successes with IOTerminal and he had the same DTC’s.
    I don’t know if this ECU’s are really resettable ? Maybe you can’t exchange them ?

    I have already readed this topic, but my ecu don't have any flash issues. I have also updated ECU via SPS online tech2web.
    I'm beginning to have doubts if this ECUs are really resetable without IOTerminal.
