Programmable Parameters

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 ID routine. If WDS or NGS tester was not able to communicate with old module during vehicle ID routine, programmable parameters may be used to return controlled features to their altered state.
