Corsa DTCs

This?

this ays how to interpret the flashes:

I only saw the top bit with the list of codes, cba to read the rest !! never mind.

That was in the post I linked to!

Yes I saw that but it doesn't answer the question of how the digits obtained from the flashes correspond with the obd2 codes.

There are a couple of posters with similar outputs of 4 digits starting with 6 and one guy also notices the flashes are not the same length.

I am beginning to form the opinion that this method is a relic and the output may have no discernable meaning.

I'll see if the obd2 port can be replaced.

They would be identical numeric values surely?

There appears to be some vehicles of identical model where it works, and others where it doesn't.

Perhaps if the vehicle has had an ECU update in its lifetime, the new software removes the facility.

That would be the best solution. If it was mine, I'd look to get the port and wiring from a scrapper, and splice it in.

It doesn't seem so. The Engine codes are P0??? but a number of us are reading 6???, the forum suggests the first digit being zero would count 10 flashes.

Yes that's the current plan
