Programmable Parameters
WARNING: This page is about a different car, the 2002 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
Programmable parameters are controlled features that can be modified while in service, typically by the customer. If a module that has been modified by programmable parameters needs replacement, Programmable Module Installation (PMI) procedure will maintain parameters in their altered state if Worldwide Diagnostic System (WDS) tester or New Generation Star (NGS) tester was able to communicate with old module during Vehicle Identification (VID) routine. If diagnostic tool tester was not able to communicate with old module during VID routine, programmable parameters may be used to return controlled features to their altered state.
