VIN checksum and 10th Digit Model Year Validation

The VIN of a unit is validated in the Unit Details, Deal Details, and Service Invoice forms.


VIN checksum and 10th Digit Model Year Validation 

The VIN of a unit is validated in the Unit Details, Deal Details, and Service Invoice forms. Validation is done in two steps:

• Validate integrity of the entire VIN value
• If valid, validate VIN 10th digit to match unit’s year

Any Invalid VIN values are displayed in Red colour. When the user hovers their mouse over the invalid VIN box a tool-tip message says “Invalid VIN format or Year mismatch”. 

The same validation process is applied to the Chassis Serial number in comparison to the Chassis Year.
