a bit of a longer pause will happen before the next trouble code will flash, again 3 times. Once all trouble codes have flashed it will flash code 12 again.

If it doesn't flash a code 12 then the ECM / PCM does not self check good and you need another one.
I had one where the circuit board broke free of the case and was in limp home mode that wouldn't flash a code 12.
