Tools we use for this vehicle
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

WHAT WE RESOLVE
12th Gen (T1XX) (2021-2026) common module and ADAS issues
- ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. Documented systems include Forward Camera (Monocular), Forward Radar (Bosch MRR, 77GHz), Blind Spot Monitor (Aptiv SRR, 24GHz), and Rear View Camera. Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve Sensing & Diagnostic Module (SDM) and Sensing & Diagnostic Module (SDM) (2022). Part numbers and crash-data workflow are confirmed for the exact year/VIN.
- Replacement module setup ECU/PCM replacement programming, BCM configuration, TCU/TCM cloning, ABS/EBCM setup are represented in the merged generation data. Rows with year ranges do not apply to every model year; verify by VIN.
