Key Features of v4.27.20 Lite

Updated Vehicle Support: Added support for the latest G-series chassis codes.
Bug Fixes: Resolved communication errors found in previous versions (v4.27.xx) regarding specific Hybrid models.
Database Updates: Corrected part numbers and labor operation codes for coding and diagnostics.
