I haven´t found a DTC-list specifically for my box to C13N-engine.
After looking inside spare boxes,
The box from Corsa A 1988, C13N, is a 160 Baud box.
The box from Corsa A 1989, C13N, is a 8192 Baud box, I think, since it has SXR-chip (U2) and a U5-chip. See photo below.

That looks like our 16206305 ECM.
See my second last post on 1st page of thread.

Ok, In your link, the"808" to the left lacks the U2, but has the U5, what has U5 for function ?
The U2, SXR-chip seems to give 8192 baud capability.
Can I use the -89/8192 baud-box as a direct replacement to my -87/160 baud-box without destroying samething, or do I need to change the harness in the car too?
I know I cant get 8192-baud ability from my -87 diagnostic port since it lacks some pins & cables. Is it possible to add some needed extra cables to get full functionality without the need to replace whole harness (or part of harness) ?
Thanks,
Anders

Some info re U5:

You would have to check all your pin assignments to see if it was compatible with your -89/8192.
Do you have a service/ workshop manual?

Fault code presented was 35, which should be IAC, changed that IAC to a brand new one, fault still there, changed back to the old IAC. Changed TPS to a brand new one and the fault has not occured anymore. Maybe need another fault code list to interpret faults right. Is there a fault code list where faulty TPS gives 35 as fault code?
Thanks,
Anders
