Programmable Parameters
WARNING: This page is about a different car, the 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
If a module that has been modified using programmable parameters needs to be installed, the PMI procedure will maintain the parameters in their altered state if the WDS is able to communicate with the old module during vehicle identification. Otherwise you may need to use programmable parameters to return them to the altered state.
