Triggers for ADAS recalibration
Windshield Replacement
SmartSense forward camera (99210-AA000) static calibration required after any windshield replacement. GDS ADAS calibration menu: guided procedure. Level surface required. Target placement: approx. 2.5m from vehicle front center (verify exact distance in GDS calibration screen before placing target - do not rely on approximation alone). No obstructions in camera field of view during calibration. Verify camera DTC clear after calibration.
Forward Camera Replacement
Same as windshield calibration procedure. GDS ADAS guided static calibration. Camera initialization + calibration via GDS. Verify all SmartSense functions (FCA, LKAS, LFA, Smart Cruise) active and DTC-free after completion. SE trim: FCA only - confirm feature set active matches trim.
Front Bumper / Radar Repair or Replacement
Front radar (99110-AA000) alignment and ADAS calibration required after bumper removal or radar replacement. GDS ADAS calibration - radar alignment check. Verify radar mounting bracket is undamaged and torqued to spec before calibration. Verify Smart Cruise Control and FCA DTC-free after calibration.
Rear Bumper / BSM Sensor Replacement
GDS BSD sensor initialization for replaced sensor(s). No static target calibration for BSD - function test: verify BCW and RCCA detection with adjacent object. GDS DTC clear. Road verify at 20+ mph.
ABS / ESC Module Replacement
GDS ABS/ESC initialization + automated brake bleed via GDS (58910-AA300). SAS zero-point reset via GDS. Drive straight on level surface at 35+ mph for SAS self-calibration. Verify no ABS/ESC/VSM DTC after calibration.
Wheel Alignment / Steering Component Work
SAS zero-point reset required via GDS after any alignment or steering component service. Drive straight 35+ mph on level road. ESC/VSM warning remains active until SAS learning is complete.
ECM Replacement
GDS ECM programming via Programming Port (calibration file download) + VIN registration + IMMO re-link. Throttle idle learn after replacement. Verify no ECM DTC. Confirm SmartSense ADAS functions still active after ECM reprogramming - forward camera may require re-initialization.
BCM Replacement
GDS BCM variant coding and option configuration required - all trim options and build codes must match vehicle VIN. IMMO re-link required after BCM replacement (BCM hosts IMMO4 on CN7). Verify all body functions (lighting, locks, windows, smart key entry) operational after programming.
Smart Key / Add Key / AKL
PIN-based AKL procedure via Hyundai Tech Info (HMT) or GDS subscription + dealer authorization. No OBD pin extraction. All existing keys erased on AKL. All customer keys must be present for re-registration. Max 8 keys. Verify all keys start vehicle after completion.
HEV High-Voltage Work (Hybrid trims only)
GDS HV mode required. HV service disconnect mandatory before any hybrid ECU or HV battery work. Insulated tools and appropriate PPE required. GDS HCU (39400-03HH0) or HV battery ECU (37501-03HB0) programming after replacement. Verify HV DTC-free and cell balance within spec after programming.
Any Front-End Collision
Inspect and recalibrate forward camera after any front-end collision using GDS Mobile.
Forward Radar Replacement
Radar module replacement requires alignment/calibration using GDS Mobile.
Mirror Replacement
If BSD sensor is mirror-integrated, recalibration required. Verify sensor location; use GDS Mobile if applicable.

FREQUENTLY ASKED QUESTIONS
FAQ
How much does ADAS calibration cost for a 2021 Hyundai Elantra?
ADAS calibration pricing for a 2021 Hyundai Elantra depends on which of its 6 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 Lane Keep Assist / Lane Departure Warning (LKA/LDW). 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 2021 Hyundai Elantra?
Yes. The 2021 Hyundai Elantra 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: 80310-AB000. 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 2021 Hyundai Elantra?
After windshield replacement on a 2021 Hyundai Elantra, Forward Camera (Monocular), Forward Radar (77GHz), 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 2021 Hyundai Elantra module service take?
Most 2021 Hyundai Elantra onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 26 programmable modules documented in our database (6 ECU, 3 BCM, 2 TCU, 4 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 2021 Hyundai Elantra 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 2021 Hyundai Elantra. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2021 Hyundai Elantra programming?
Every programming, cloning, and calibration job on the 2021 Hyundai Elantra 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 2021 Hyundai Elantra can you actually service?
We program, clone, repair, or replace the full programmable-module stack on a 2021 Hyundai Elantra. For this vehicle our database documents:
- 6 engine control (ECU/PCM)
- 2 transmission control (TCU/TCM)
- 3 body control (BCM and related)
- 4 ABS / brake control (EBCM)
- 4 immobilizer / security
- 3 key & fob
- 2 instrument cluster (IPC)
- 1 steering angle sensor (SAS)
- 6 ADAS module
