TOOL ACCESS MATRIX

Tools we use for this vehicle

We provide the software and equipment for the agreed work. The exact tool and procedure depend on your year, VIN and module.

Factory scan, coding, and calibration access

GM GDS2 / GM Tech2Win / GM MDI 2

Factory routines and secure server authorization control this path when aftermarket coverage is not enough for the VIN.

ADAS scan, setup, and verification

Autel, Launch Tech, Topdon

Used where aftermarket coverage supports the procedure; OEM software remains required for locked factory routines.

Bench cloning and chip-level recovery

Alientech / Autotuner / Orange5 / Scanmatik / Flex / VVDI2 / PCMFlash / CGDI / X-Prog

Used only when the module, donor data, EEPROM, MCU, or crash-data workflow requires bench or chip-level handling.

Bench/chip-level only
