0 No errors
1 VIN has zero length
2 VIN contains improper characters
3 VIN length less than 7 characters
4 VIN does not match any valid pattern
5 Make code not valid for VIN pattern
6 VIN model year/pattern conflict
7 Recognized VIN, inappropriate vehicle type
8 Recognized VIN, inappropriate vehicle make
9 Series/model key not in table
-1 Invalid engine code
-8 Invalid check digit
-9 Invalid check digit/engine code
10 Series/model key in table, model year bad
12 VIN not in U.S. standard format (gray market vehicle)

STRENGTHS AND WEAKNESSES:
This data element relies upon the accuracy of the reporting officer and the
ability of reporting officers to be consistent in their evaluations. Furthermore,
it is a driver specific field. Thus, a two vehicle crash may have two different values,
one for each driver. However, every occupant within the same vehicle as a particular
driver will have this data element, so the analyst must carefully restrict
analysis of this data element to driver-specific questions.
