Further to an engine replacement, my Corsa did not start and the engine light (EML) is now flashing. Here is the whole story: http://www.corsa-b.co.uk/forum/viewtopi ... 54&t=20720.
So I purchased an OP-COM and I do have a P1503 error code:
My question is to know whether the transponder (the chip in the key, I mean) is dead or de-progammed, or this is the immobiliser card which is dead or de-progammed.P1503 - Immobiliser Wrong Signal
(00) - Present
BTW, what does the 2nd line mean: (00) - Present ? Does it mean that the immobiliser was found OK, or a transponder was found but not with the right code ?
So what can I do given that I don't have the security code to re-programm the transponder, and before paying Opel to get this code I'd know whether this code will be required or not ?
Thanks in advance for your help.
