Position 7 in a real VIN

KL4CJASB3MB961596 → 7th character = S

Here it is S, part of the descriptor block CJASB for this Buick Encore.

The 7th character continues the VDS. Manufacturers often use it for the restraint system (seat belts / airbags) or an additional model/body detail.

As with the rest of positions 4–8, there is no universal table — the character is interpreted using the maker's own descriptor scheme.
