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
2nd Gen (C1XX) (2018-2023) 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) (2018-2021, 2023), Forward Radar (Bosch MRR, 77GHz) (2018-2021, 2023), Blind Spot Monitor (Aptiv SRR, 24GHz) (2018-2021, 2023), and Rear View Camera (2018-2021, 2023). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve Sensing & Diagnostic Module (SDM) (2018-2019), Sensing & Diagnostic Module (SDM) (2018), and 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.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Chevrolet Traverse (2018-2023) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Chevrolet Traverse (2018-2023). The merged generation data includes ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS coverage. Rows marked with a year range apply only to that part of the span; unmarked rows are present across the merged generation data.
Which modules are documented for Chevrolet Traverse (2018-2023)?
The Chevrolet Traverse (2018-2023) generation currently shows 16 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include Sensing & Diagnostic Module (SDM) (2018-2019), Sensing & Diagnostic Module (SDM) (2018), and Sensing & Diagnostic Module (SDM). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 84395259 (2018-2019) - confirm for your exact year/VIN.
Does Chevrolet Traverse (2018-2023) need ADAS calibration after glass or collision work?
The merged generation data documents 8 ADAS systems, including Forward Camera (Monocular) (2018-2021, 2023), Forward Radar (Bosch MRR, 77GHz) (2018-2021, 2023), Blind Spot Monitor (Aptiv SRR, 24GHz) (2018-2021, 2023), Rear View Camera (2018-2021, 2023), and Rear Cross Traffic Alert (RCTA) (2018-2021, 2023).

Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on Chevrolet Traverse (2018-2023)?
Yes. The generation data includes 9 SRS records, including Sensing & Diagnostic Module (SDM) (2018-2019), Sensing & Diagnostic Module (SDM) (2018), and Sensing & Diagnostic Module (SDM). Bench reset, cloning, and replacement setup are handled after part-number review. Any SRS part number shown for this generation is planning data only - confirm for your exact year/VIN. Reference part number: 84395259 (2018-2019) - confirm for your exact year/VIN.
Do all Chevrolet Traverse (2018-2023) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2018-2023; any row that does not span all data-bearing years is printed with its year range or treated as varies by year - verify by VIN. Part numbers always require exact year/VIN confirmation before ordering, cloning, or programming.
How long does service take for Chevrolet Traverse (2018-2023)?
Most programming, cloning, SRS, and calibration jobs are quoted after VIN, DTC, part number, and repair-scope review. Labor time varies by year - verify by VIN before scheduling. Mail-in module service is available nationwide. Exact service eligibility is confirmed from the year, VIN, module, and requested scope.
Is Chevrolet Traverse (2018-2023) service mobile or mail-in?
