Designates the year. "K" indicates the year 2000. Years progress or regress in alphabetical order.
"J" is 1999, "L" is 2001, "M" is 2002, and so on. The letters "I" and "O" were skipped.
Designates significant part changes within the same year for this model. Base is 0 and this number
advances for each change.
Example: P-1
"P" indicates 2004.
"1" indicates the first significant part change for 2004.
