Programmable Parameters
WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 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 will maintain 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 them to the configured state.
