I think I know what you are going to say, but I kinda got there first!
Doh!

For those reading this and wondering WTF.
It (the ECU codes) will keep repeating the code, UNTIL you force it to step to the next code, using the same method as you did to start the sequence.

So. I got there.
And the result is, my ECU sees a fault with the O2. That is the only code for ECU.
And TCU is no codes stored.

Simples.

Display output can wait until tomorrow, assuming no Glasgow sunshine.
And getting into the output test can wait until then, also.
