Programming the VID Block For A Replacement PCM

The VID block on a replacement PCM is blank and requires programming. There are two procedures available. The first is an automatic data transfer from the old PCM to the new PCM, 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 using 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 it has been installed.

On some vehicles, the VIN, tire size, axle ratio, and cruise control configuration are communicated to the PCM from the body control module (BCM) or the instrument panel cluster (IPC). If a new PCM is installed, the new PCM obtains this data the first time the ignition is turned to the ON position. If the data is not received DTCs U0140 and U0422 set and DTC P0630 may set. If the data is received but the values are invalid or not configured, DTC U0422 sets and DTC P0630 may set. If the data received is valid but the proper learning command has not been received from the diagnostic tool, DTC P160A sets. There are associated PIDs to indicate the status of each data item.

Carry out manual data entry if the old PCM is damaged or incapable of communicating. Remove and install a new PCM. Using a compatible scan tool, select and carry out the module/parameter programming, referring to the scan tool manufacturer's instruction manual. Make certain that all parameters are included. Failure to correctly program tire size in revolutions per mile, (rev/mile equals 63, 360 divided by the tire circumference in inches), axle ratio, 4x4 or 4x2, or MSOF and ESOF may result in DTCs P1635 and 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 and Lincoln technicians, contact your National Hotline or the Professional Technician Society (PTS) web site for As-Built data listed under the Service Publications Index. Non-Ford technicians use the Motorcraft® web site at www.motorcraft.com. From the Motorcraft® home page, use the search function to find the Module Programming or As-Built Data.

For Ford and Lincoln technicians, check the Programmable Module Installation link on the PTS web site for quick Programmable Module data information by vehicle.
