WHAT WE RESOLVE
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) (2021), Forward Radar (77GHz) (2021), Blind Spot Monitor Sensor - Left (BSM) (2021), and Blind Spot Monitor Sensor - Right (BSM) (2021-2022). 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) (2023-2026). 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.
- Gateway, key, and immobilizer access Gateway, key, and immobilizer procedures are represented by 16 merged security records. Access and all-keys-lost support varies by year - verify by VIN.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program GMC Yukon XL (2021-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the GMC Yukon XL (2021-2026). 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 GMC Yukon XL (2021-2026)?
The GMC Yukon XL (2021-2026) generation currently shows 40 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include Sensing & Diagnostic Module (SDM) and Sensing & Diagnostic Module (SDM) (2023-2026). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 13518546 - confirm for your exact year/VIN.
Does GMC Yukon XL (2021-2026) need ADAS calibration after glass or collision work?
The merged generation data documents 22 ADAS systems, including Forward Camera (Monocular) (2021), Forward Radar (77GHz) (2021), Blind Spot Monitor Sensor - Left (BSM) (2021), Blind Spot Monitor Sensor - Right (BSM) (2021-2022), and Surround View Camera System (4-camera) (2021). Calibration triggers include Windshield Replacement (if ADAS Camera Equipped) (2021), Forward Camera Replacement (2021), Forward Radar Replacement (2021), and BZA Rear Radar Replacement (either side) (2021). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on GMC Yukon XL (2021-2026)?
Yes. The generation data includes 4 SRS records, including Sensing & Diagnostic Module (SDM) and Sensing & Diagnostic Module (SDM) (2023-2026). 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: 13518546 - confirm for your exact year/VIN.
Do all GMC Yukon XL (2021-2026) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2021-2026; 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.
Can you program keys or immobilizer systems for GMC Yukon XL (2021-2026)?
Yes, where the VIN and security workflow support it. The generation data includes 16 gateway, immobilizer, or key-security records. Gateway modules include Central Gateway Module. Key records are present in the merged generation data. Security access, all-keys-lost eligibility, and add-key workflows vary by year - verify by VIN.
How long does service take for GMC Yukon XL (2021-2026)?
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 intake is temporarily unavailable; do not ship a module unless support confirms next steps.
Is GMC Yukon XL (2021-2026) service mobile or mail-in?
Mobile service covers DFW on-vehicle diagnostics, key programming, post-repair coding, and supported module work. Mail-in module intake is temporarily unavailable. We confirm the active path for your exact year/VIN before scheduling; do not ship a module unless support confirms next steps.
