Check the 10th digit of the vin number. If its newer then a 2000 then the 10th digit will be the year.
The 10th digit is the year no matter what year it is. They are like car VIN #s.
A=1981
B=1982
and so one until you get to Y
Y=2000
then they use the last number of the year like Yunt said
1=2001
2=2002
you get the idea
