Vehicle Identification (VID) Block

Some powertrain control module (PCM) may contain a memory area called a vehicle identification (VID) block. The VID block is used to store powertrain configuration information. The PCM VID block may contain the factory settings for the configurable modules unless the PCM has been flashed with a new calibration, in which case some PCM parameters may be modified.
