Vehicle Identification (VID) Block
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Some PCMs contain a memory area called a VID block.
The PCM VID block may contain the factory settings (as built data) for the configurable modules unless the PCM is flashed with a new calibration, in which case some PCM parameters may be modified.
