Triggers for ADAS recalibration
Windshield Replacement Affected: Autopilot forward camera, all camera-based ADAS features
Forward camera must be re-mounted to OEM specification and calibrated via Tesla service mode after windshield replacement. Static calibration target required. Autopilot will be disabled until calibration is complete and customer re-accepts terms. Use Tesla-approved glass - aftermarket glass with different optical properties can cause calibration failure.
Front Bumper Repair or Replacement Affected: Front radar (HW2.5), front cameras, ultrasonic sensors
Front radar aim calibration required via Tesla service mode. Front bumper ultrasonic sensors must be re-initialized. Inspect radar mounting bracket before calibration. Verify Autopilot and collision avoidance DTC-free after repair.
Rear Bumper Repair Affected: Rear camera, rear ultrasonic sensors
Rear camera re-mount and calibration if disturbed. Rear ultrasonic sensor re-initialization. Verify park assist and Autopilot rear monitoring DTC-free.
Any Collision Affected: SRS ECU, all deployed modules, all ADAS systems
CRITICAL: Tesla SRS system is NOT user-serviceable. Tesla Service Center required for all SRS module replacement and crash data clearing. Full ADAS system scan and calibration required after any collision. Do not return vehicle to customer with SRS warning active.
HV Battery or MCU Work Affected: BMS, MCU, all HV-adjacent systems
HV SAFETY: mandatory HV disconnect, 5-minute wait, verify <60V before work. Tesla service mode required for all HV module programming. BMS cell balance verification after replacement. Road test required after HV system work. Trained HV-certified technician required.
Forward Camera Replacement
Camera module replacement requires full recalibration using Tesla Toolbox.
Forward Radar Replacement
Radar module replacement requires alignment/calibration using Tesla Toolbox.

FREQUENTLY ASKED QUESTIONS
FAQ
How much does ADAS calibration cost for a 2018 Tesla Model 3?
ADAS calibration pricing for a 2018 Tesla Model 3 depends on which of its 4 documented systems need work after a repair. This vehicle is documented with Autopilot Forward Camera (main, HW2.5), Autopilot Forward Radar (HW2.5), Autopilot Side/Rear Cameras (x6, HW2.5), and Ultrasonic Sensors (12x, Autopilot). 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 2018 Tesla Model 3?
Yes. The 2018 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. 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 2018 Tesla Model 3?
After windshield replacement on a 2018 Tesla Model 3, Autopilot Forward Camera (main, HW2.5), Autopilot Forward Radar (HW2.5), and Autopilot Side/Rear Cameras (x6, HW2.5) 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 2018 Tesla Model 3 module service take?
Most 2018 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 14 programmable modules documented in our database (3 ECU, 2 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 2018 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 2018 Tesla Model 3. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2018 Tesla Model 3 programming?
Every programming, cloning, and calibration job on the 2018 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 2018 Tesla Model 3 can you actually service?
We program, clone, repair, or replace the full programmable-module stack on a 2018 Tesla Model 3. For this vehicle our database documents:
- 3 engine control (ECU/PCM)
- 1 transmission control (TCU/TCM)
- 2 body control (BCM and related)
- 1 ABS / brake control (EBCM)
