ECU / Engine

ECM - L3B 2.7L Turbo 4-cyl 2 records
12697 (APPROX - VERIFY GMDB BY VIN) Verify by VIN 2019 SPS / TIS2WEB

Documented for 2019 within this generation. Confirm the exact vehicle by VIN.

Coverage and replacement notes

Documented years: 2019

Year coverage is not proof of interchangeability. Confirm the full part number and vehicle configuration before buying a used module.

Access

Located: Engine bay periphery - mounted in the front driver-side wheel well area, behind the inner fender felt liner (not on the engine itself).

Reach it from the front driver-side wheel well: the felt/splash liner inside the fender opening is pulled back to expose the module on its bracket, then the electrical connectors are unplugged. No interior dash work needed. This is a change from older GM trucks where the ECM sat on the engine - on this generation it lives at the wheel well.

Disconnect the battery first.

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

Coverage and replacement notes

Documented years: 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026

Year coverage is not proof of interchangeability. Confirm the full part number and vehicle configuration before buying a used module.

Access

Located: Cabin - under the driver-side dash, near/left of the brake pedal behind the lower dash trim.

Reached from the driver footwell by removing the lower dash trim panel (and on some builds a lower vent duct) to expose the gateway module on its bracket, then unplugging the connectors.

WHAT WE RESOLVE

4th Gen T1XX (2019-2026) 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) (2019), Forward Radar (77GHz) (2019), Blind Spot Monitor Sensor - Left (BSM) (2019), and Blind Spot Monitor Sensor - Right (BSM) (2019). Year-marked systems apply only to the shown range.
  • SRS crash-data and warning light SRS service can involve Sensing & Diagnostic Module (SDM) (2019), Sensing & Diagnostic Module (SDM) (2019-2021, 2023), and Sensing & Diagnostic Module (SDM) (2019-2021). 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 GMC Sierra 1500 (2019-2026) modules?

Yes. Core Auto Logic supports generation-scoped module programming for the GMC Sierra 1500 (2019-2026). 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 Sierra 1500 (2019-2026)?

The GMC Sierra 1500 (2019-2026) generation currently shows 78 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include Sensing & Diagnostic Module (SDM) (2019), Sensing & Diagnostic Module (SDM) (2019-2021, 2023), and Sensing & Diagnostic Module (SDM) (2019-2021). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 84057079 (2019) - confirm for your exact year/VIN.

Does GMC Sierra 1500 (2019-2026) need ADAS calibration after glass or collision work?

The merged generation data documents 22 ADAS systems, including Forward Camera (Monocular) (2019), Forward Radar (77GHz) (2019), Blind Spot Monitor Sensor - Left (BSM) (2019), Blind Spot Monitor Sensor - Right (BSM) (2019), and HD Rear Camera (2019). Calibration triggers include Windshield Replacement (if Forward Camera Equipped) (2019), Forward Camera Replacement (2019), Forward Radar Replacement (2019), and BZA Rear Radar Replacement (either side) (2019). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.

Can you reset the airbag module on GMC Sierra 1500 (2019-2026)?

Yes. The generation data includes 29 SRS records, including Sensing & Diagnostic Module (SDM) (2019), Sensing & Diagnostic Module (SDM) (2019-2021, 2023), and Sensing & Diagnostic Module (SDM) (2019-2021). 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: 84057079 (2019) - confirm for your exact year/VIN.

Do all GMC Sierra 1500 (2019-2026) years use the same parts?

No assumption should be made across the full span. The generation page merges rows across 2019-2026; 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.

How long does service take for GMC Sierra 1500 (2019-2026)?

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 service is available nationwide. Exact service eligibility is confirmed from the year, VIN, module, and requested scope.

Is GMC Sierra 1500 (2019-2026) service mobile or mail-in?

Mobile service covers DFW on-vehicle diagnostics, post-repair coding, and supported module work. Mail-in module service is available nationwide. We confirm the active path for your exact year, VIN, module, and requested scope before service.
