Programmable Module Installation (PMI)

NOTE: If the powertrain control module (PCM) needs to have a powertrain calibration flash programmed, make sure to use the flash cable when programming calibrations or running a PMI routine on the PCM.

The PMI configuration method is used when a new programmable module is to be installed. During the PMI routine the diagnostic tool attempts to gather two pieces of information:

option content information from the old module (module configuration and customer preference settings)
the vehicle identification number (VIN) from the PCM
During PMI the diagnostic tool first looks to the PCM for the VIN of the vehicle. Once the VIN is retrieved the diagnostic tool will carry out a self-test of the suspect module to determine if the module has been configured.

If DTC B2477 is present the module does not contain complete configuration information. The PMI routine will then halt and give instructions on how to proceed.
If DTC B2477 is not present the module will allow the diagnostic tool to retrieve its option content information. The diagnostic tool will then store the option content information and the VIN.
The diagnostic tool can store the combined option content information and VIN for only one module at a time. Once information is stored, the diagnostic tool cannot be used to retrieve any other option content information without erasing the previous option content information. Make sure the new module is on hand for installation before retrieving option content information data from the old module.

After the new module is installed, use the diagnostic tool to restore the option content information into the new module.
