Programmable Module Installation (PMI)
The PMI method is used when a new programmable module is installed on the vehicle. It is no longer necessary to command the diagnostic tool to gather module option content from the old module. The diagnostic tool automatically obtains any available module option content information from the old module during the vehicle ID routine that runs when the diagnostic tool is initially connected to the vehicle. It is important that the diagnostic tool is connected to the vehicle and allowed to identify the vehicle and obtain configuration data prior to any module removal.
If a module that has been modified using programmable parameters needs to be installed, the PMI procedure maintains the parameters in their altered state if the diagnostic tool is able to communicate with the old module during vehicle ID. Otherwise, you may need to use programmable parameters to return the parameters to the altered state.
