Confusing flashing while pulling codes
 

I pulled my codes today (JDM car) and got:

Long flash (~2 sec) 8 short flashes 1 long flash 1 medium long break (~1 sec) 1 medium long flash and the pattern repeated without any break.

I'm confused, this doesn't match the manual :scratch:, where is the 4 second break between code cycles. No pause between long and short flashes for the first code. No pause between codes (if there were more than 1 code). Medium long flash, what to say about that?

I'm guessing I have a code 18 (throttle position sensor (narrow)) but what to tell from the rest of the flashing?
