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

Windshield Replacement Affected: FEC Camera, FCA, AEB, LKA, Super Cruise (RS)

FEC static calibration required. Super Cruise RS: FEC prerequisite before re-enable. Attention camera verify after windshield work. OEM-quality acoustic/thermal glass required on Blazer EV.

Front Bumper Repair Affected: Front Radar, ACC, AEB, Super Cruise (RS)

Radar aim via GDS2. Super Cruise: radar + FEC both required. Inspect bracket.

Rear Bumper Repair Affected: SBZA Sensors, RCTA

SBZA init via GDS2 if sensors removed. Drive-off self-cal after PMI.

HV Battery or Drive Motor Work Affected: BMS, Front/Rear Motor MCU, OBC, EBCM

HV SAFETY CRITICAL: mandatory HV disconnect, 5-min wait, verify <60V. SPS for all HV-adjacent modules. BMS cell balance verify. Regen verify after motor or EBCM work. HV-certified tech required.

Any Collision Affected: SDM, all airbags, FEC, Front Radar, SBZA, HV system

HV isolation test mandatory after any collision on BEV. SDM crash clear or replace. Full ADAS recalibration. Do not return to service with HV isolation fault or unresolved SRS/ADAS DTC.

Forward Camera Replacement

Camera module replacement requires full recalibration using GDS2/MDI2.

Forward Radar Replacement

Radar module replacement requires alignment/calibration using GDS2/MDI2.

BSM Sensor Replacement

Blind spot monitoring sensor replacement requires calibration using GDS2/MDI2.

Mirror Replacement

Surround view mirror camera recalibration required after mirror R&R. Use GDS2/MDI2.

WHAT WE RESOLVE

1st Gen (2024-2026) 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 (77GHz), Super Cruise (RS trim RPO UDD), and Blind Spot Monitor Sensor - Left (BSM). Year-marked systems apply only to the shown range.
SRS crash-data and warning light SRS service can involve Sensing & Diagnostic Module (SDM). 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.
