Vehicle Identification (VID) Block
Vehicle Identification (VID) block commonly stores powertrain configuration items such as VIN , tire size, axle ratio, and whether or not the vehicle is equipped with cruise control.
Transmission Identification Block
The SOBDMC ( TCM ) contains a memory area called a transmission identification block. The transmission identification block commonly stores solenoid body flow data. If the solenoid body information is not correct, transaxle damage or drivability concerns can occur.
As-Built Data
As-Built data is a VIN -specific module configuration record. During vehicle build, the configuration from all modules is downloaded and stored in the As-Built database. As-Built data does not reflect customer preference items that have been changed from the default state. These items need to be changed using programmable parameters after the module is configured.
It is not necessary to obtain As-Built data unless directed to do so by the scan tool. This data may be accessed from the technician service publication web site.
