WHAT WE RESOLVE
1st Gen (2017-2026) 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) (2017, 2024-2026), Forward Radar (77GHz) (2017, 2024-2026), Blind Spot Monitor Sensor - Left (BSM) (2017, 2024-2026), and Blind Spot Monitor Sensor - Right (BSM) (2017, 2024-2026). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve SRS Airbag Control Module (ACU) (2017), SRS Airbag Control Module (ACU) (2018), and SRS Airbag Control Module (ACU) (2019). 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 Tesla Model 3 (2017-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Tesla Model 3 (2017-2026). 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 Tesla Model 3 (2017-2026)?
The Tesla Model 3 (2017-2026) generation currently shows 51 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Airbag Control Module (ACU) (2017), SRS Airbag Control Module (ACU) (2018), and SRS Airbag Control Module (ACU) (2019). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 1086052-00-A (2021, 2023) - confirm for your exact year/VIN.
Does Tesla Model 3 (2017-2026) need ADAS calibration after glass or collision work?
The merged generation data documents 23 ADAS systems, including Forward Camera (Monocular) (2017, 2024-2026), Forward Radar (77GHz) (2017, 2024-2026), Blind Spot Monitor Sensor - Left (BSM) (2017, 2024-2026), Blind Spot Monitor Sensor - Right (BSM) (2017, 2024-2026), and Rear View Camera (2017, 2024-2026).

Reference part number: 1086052-00-A (2021, 2023) - confirm for your exact year/VIN.
Do all Tesla Model 3 (2017-2026) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2017-2026; 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 Tesla Model 3 (2017-2026)?
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.
