 The message in the lower left corner indicates whether the VIN passed or        failed the edit. An asterisk (*) prior to a message in the meaning column       indicates that the digit on that line does not conform with the rest of         the information given.                                                                                                                                          Before trying to correct a VIN, verify  that the vehicle make, body style       and year are correct for the vehicle in question.                                                                                                               To correct a digit, move the highlight bar (cursor) up or down the Digit        column using the arrow keys. When the bar is positioned on the desired          digit to be changed, press the ENTER key. A window will appear with             the possible selections conforming to that particular make, model, and year.    For example, if you press ENTER when the highlight bar is on the engine         digit for a 1988 Ford Mustang vin, the window would only display                engines installed in a Ford Mustang in 1988.                                                                                                                                                                                                                                                                                                                                                                    In front of some of the possible selections, there may be an asterisk.          These asterisks indicate that if one of these options is selected, the new      digit would cause the calculated check digit to conform with the check          digit in the VIN. These are possible selections only and should be used         judiciously.                                                                                                                                                    To select a digit from the window, type in the digit or move the cursor         to the desired option and press ENTER. To leave a window without changing       the digit, press F3 - not ENTER.                                                                                                                                Changing a digit in the VIN can cause error conditions in other digits.         If this happens, either the digit you changed is in error or the other          digit(s) is in error. Even if there are no error conditions and the             VIN passed the test, the car which the VIN represents may not have              been actually made. Final confirmation should be made with NICB's               shipping records.
