WARNING: This page is about a different car, the 2004 Ford Explorer Sport Trac. However, it is still accessible from the selected car via links, so may be relevant.

Calibration Update: Some modules are designed to be flashed or reflashed with complete new software packages. This process of reflashing the module is a calibration update.

Programmable Parameters: These are options contained within the existing software. These include items such as tire size, customer preference items and anti-theft options. The current settings are downloaded from an existing module then uploaded to a new module. They can also be configured using the diagnostic tool. Programming parameters is different from updating calibrations as no software is changed, only the options already in the software.

Some modules must be programmed during a repair procedure. If the procedure is not carried out, the module will not function correctly and may set a number of diagnostic trouble codes (DTCs). DTCs B2477 or P1639 indicate necessary data has not been programmed into the module.

Modules that require programming should not be transferred between vehicles. The parameter values or settings are unique to each vehicle and if not set correctly will cause a fault.

WDS will automatically attempt to retrieve the module configuration information. If the module does not contain the correct information, the diagnostic tool will request "As Built" data, or display a list of items that will require manual configuration. The diagnostic tool will program the module based on the manual data entered.

For additional WDS/diagnostic tool programming procedures, refer to PROGRAMMABLE MODULE INSTALLATION (PMI) .

There are three different methods that are used for module programming:

Programmable module installation (PMI)
Calibration update
Programmable parameters

Some modules do not support all three methods.
