Definition of Terms: 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.
