Programmable Parameters
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. 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 maintains the configured parameters if the diagnostic tool is able to communicate with the old module during vehicle ID. Otherwise, programmable parameters may be needed to return the module to the configured state.
