P1639 MERCURY Description
Configurable modules accommodate a variety of vehicle options, eliminating the need for many unique modules for one vehicle line. These modules must be configured when replaced as part of a repair procedure. Configurable modules should not be exchanged between vehicles since the settings are unique to each vehicle. Failure to configure a new module may result in improper operation.
The Diagnostic Trouble Code (DTC) indicates that the Vehicle Identification (VID) block is not programmed or is corrupt.
