90degree

I have just done the Hicus code check and do not understand the results. From what I have read about the Hicus codes is, Long flash = first digit, short flash = second digit. Mine is a 1990, so code faults only go from 1 to 9. My result was: 6 short flashs, 1 long flash, 2 short flashs, 1 long flash, and then a gap till it starts over again. How do I get a single digit from this? Thanks.
