Principles of Operation: Notes

WARNING: This page is about a different car, the 2003 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

Some modules must be programmed as part of the repair procedure. If this procedure is not followed the module will not function correctly and may set a number of DTCs, including B2477 or P1639, which indicate that some necessary data has not been programmed into the module.

Modules that need programming should not be exchanged between vehicles. In most cases the parameter values or settings are unique to that vehicle, and if not set correctly will cause concerns or faults.

Some programmable parameters, such as belt minder on/off, can be changed from the factory setting at the customer's request.

Worldwide Diagnostic System (WDS) will automatically attempt to retrieve the module configuration information from all modules when vehicle ID is carried out. If the module does not contain correct information, the diagnostic tool will either request "As-Built" data or display a list of items that will need to be manually configured. The diagnostic tool will program the module based on the data entered.

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

programmable module installation
calibration update
programmable parameters

Some modules do not support all three methods.
