The Service Programming System (SPS) updates the flash calibration files that are stored in a Transmission Control Module (TCM). The calibration file custom-tailors a module to a certain vehicle. The calibration file contains data for things such as 4 A/T system control. When this Vehicle Identification Number (VIN) is not contained. And when software is locked, cancel a lock and write a VIN No.
