Programming the VID Block for a Replacement PCM

The VID block on a replacement PCM is blank and requires programming. There are 2 procedures available. The first is an automatic data transfer from the old PCM to the new PCM, and the second is manual data entry into the new PCM.

Automatic data transfer is carried out if the old PCM is capable of communicating. This is done by the use of a scan tool to retrieve data from the old PCM before removing it from the vehicle. The stored data can be downloaded to the new PCM after installation.

Manual data entry must be carried out if the old module is damaged and/or incapable of communicating. Install a new PCM. Using a compatible scan tool, select and execute Module/Parameter reprogramming referring to the manufacturer's user article. Make certain that all parameters are included. Incorrectly programming tire size in revolutions per mile, (rev/mile - 63,360 divided by the tire circumference in inches), Axle Ratio, 4x4/4x2, and/or MSOF/ESOF may result in DTCs P1635 or P1639. You may be instructed to contact the As-Built Data Center for the information needed to manually update the VID block with the scan tool. Contact the center ONLY if the old PCM cannot be used or the data is corrupt. For Ford Lincoln - Mercury technicians, contact your National Hotline or the Professional Technician Society (PTS) web site for as-built data. Non-Ford technicians, use the Motorcraft website at motorcraft.com. From the Motorcraft homepage, use the search function to find the Module Programming or As-Built Data.
