Programmable Module Installation (PMI)

The programmable module installation (PMI) method is used when a new programmable module is installed on the vehicle. It is no longer necessary to command the WDS or equivalent tester to gather module option content from the old module. The WDS or equivalent tester automatically obtains any available module option content information from the old module during the vehicle ID routine that runs when the WDS or equivalent tester is initially connected to the vehicle. It is important that you connect WDS or equivalent tester to the vehicle and allow it to identify the vehicle and obtain configuration data prior to removing any modules.
