Why, do you want a 36 and 44? :D

ECM will flash 12 three times, then codes, then 12 three times again. If no codes, it will just flash 12 6 times.

36 would be: flash, flash, flash; flash flash flash flash flash. (3 times)

12 would be flash; flash flash. (three times)

Can you guess what 44 would be?

LayZ, after the first three "12"s, it flashes in succession each trouble code three times and then concludes with three "12"s.
