So we tried the other possibility, the 30 minutes one:
In the same manner, the
step by step process didn't match what we experienced either.
For instance, on the ON position, the security light never blinks. You have to put back the ignition to the OFF position to be able to wait 10 minutes before the light goes off (yes it did, we waited and counted).
Secondly, switching ON the ignition by turning the key doesn't switch on the dash and so on. You have also to press the switch from the remote control of the security system (which we have on the key holder) to put it to the ON position. So, you guess it, we did it by turning ON the key AND switching on the security remote switch each time we were asked to turn on the key.
Maybe a sensitive detail is that We're working on a EURO c5. A lot of them were equiped (by the importer or in Bowling Green, I don't know) with the same certified security system, from the unique brand TEXALARM. (Our other 2000 C5 I had bought new in 2000 had the same "oem" security system).
Anyway, even doing our best, trying to annalize and imagine every possible combinations, each time the car started for less than a second then shut off. The ECM seems to work but it looks like this
new ECM is not recognized as the right ECM on the car.
Any help will be welcomed, my buddy and I are quite lost. We would be really greatful to get a way to sort this out.
Thanks
