FREQUENTLY ASKED QUESTIONS
FAQ
How much does ADAS calibration cost for a 2026 Tesla Model 3?
ADAS calibration pricing for a 2026 Tesla Model 3 depends on which of its 8 documented systems need work after a repair. This vehicle is documented with Forward Camera (Monocular), Forward Radar (77GHz), Blind Spot Monitor Sensor - Left (BSM), Blind Spot Monitor Sensor - Right (BSM), and Rear View Camera. We provide a fixed quote after confirming the operations performed - send the VIN, the repair scope (windshield R&R, bumper work, alignment, collision), and any DTCs so the quote response can include a real number.
Can you reset the airbag light on a 2026 Tesla Model 3?
Yes. The 2026 Tesla Model 3 uses a factory SRS control module that we support. We read and clear stored crash data, then restore the module to factory status so the airbag warning light goes out and the system returns to full operation. Reference part number on this vehicle: 1084946. Mobile diagnosis and programming are available in DFW, and mail-in module service is available nationwide. Send the part number and a description of what triggered the light, and we will provide a quote and scheduling window.
What is needed after replacing the windshield on a 2026 Tesla Model 3?
After windshield replacement on a 2026 Tesla Model 3, Forward Camera (Monocular), Forward Radar (77GHz), Rear View Camera, Surround View Camera System, and Lane Keep Assist / Lane Departure Warning (LKA/LDW) rely on the forward-facing camera and require recalibration before the systems return to operation. We perform the calibration on-site in the DFW Metroplex with OE target fixtures. Mail-in module service is available nationwide for eligible module work.
How long does a 2026 Tesla Model 3 module service take?
Most 2026 Tesla Model 3 onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 10 programmable modules documented in our database (2 ECU, 1 BCM, 1 TCU, 1 ABS, plus IPC/SAS/gateway/accessory). Mobile module work and ADAS calibration are scheduled in the DFW service area after quote review. Mail-in module service is available nationwide.
Do you cover the 2026 Tesla Model 3 on-site, or is this mail-in only?
We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, post-repair recoding, and supported module work). Mail-in module service is available nationwide. Quote the work and we will confirm the active service path for the 2026 Tesla Model 3. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2026 Tesla Model 3 programming?
Every programming, cloning, and calibration job on the 2026 Tesla Model 3 is backed by a workmanship warranty covering the scope of work we performed: 1-year unlimited on all flashes, clones, and ADAS calibrations. If a module we programmed or a calibration we performed fails to function as expected, return it and we restore it at no charge. The warranty covers our work; it does not cover unrelated mechanical or electrical failure of the module itself.
Which modules on a 2026 Tesla Model 3 can you actually service?
We program, clone, repair, or replace the full programmable-module stack on a 2026 Tesla Model 3. For this vehicle our database documents:
- 2 engine control (ECU/PCM)
- 1 transmission control (TCU/TCM)
- 1 body control (BCM and related)
- 1 ABS / brake control (EBCM)
- 1 immobilizer / security
- 3 key & fob
- 1 instrument cluster (IPC)
- 1 steering angle sensor (SAS)
- 8 ADAS module
Infotainment on this platform: Tesla OS. Send the VIN and the operations performed and we will confirm support and pricing.
