Triggers for ADAS recalibration
Windshield Replacement
HDS camera static calibration required after any windshield replacement on Honda Sensing-equipped trims (EX+). Camera: 36160-TBG-A01. Use 10th gen FC/FK specific procedure in HDS. Place horizontal target board at ~1m from vehicle front bumper on level surface. No obstacles in forward zone. Approx 5-10 min via HDS guided procedure. Verify all Honda Sensing warning lamps extinguish. LX trim: no Honda Sensing - no calibration required.
Forward Camera (Honda Sensing) Replacement
HDS camera initialization + static calibration (10th gen procedure). Same target/level surface requirement as windshield procedure. Verify CMBS, LKAS, ACC, RDM all functional post-cal. Check for all Honda Sensing DTCs.
Front Radar Replacement
HDS radar initialization + static calibration. Pair with camera calibration - perform both if either is disturbed. Level surface, target at ~1m from front bumper. Verify ACC and CMBS DTCs clear.
VSA Modulator Replacement
HDS motorized brake bleed sequence required after VSA modulator (57110-TGH-315) replacement. Manual bleed alone is insufficient. Verify firm pedal. HDS ABS/VSA DTC clear. Road test at 15+ mph.
ECM Replacement (L15B7 / Si / Type R)
HDS flash programming + VIN registration + IMMO seed write. Throttle position initialization + idle learn via HDS. Verify no powertrain DTCs. Type R: use FK8-specific calibration file (37820-5U5-A62). Do not cross-apply calibration files between engine variants.
Smart Entry ECU / Keyless Access Control Unit Replacement
Honda iN dealer authorization required before procedure begins. All customer keys must be present. HDS key registration procedure. Verify all registered keys start vehicle. Max 8 keys per vehicle.
BCM (38800-TGG-A31) Replacement
HDS BCM programming + VIN/configuration data write. Verify all body electrical functions operational: locks, windows, lighting. TPMS sensor re-registration may be required after BCM replacement.
SRS ECU Replacement
HDS SRS initialization + DTC clear after module replacement. Hard deployment = replace SRS ECU only - no crash data clear. CRITICAL: Takata recall VIN check required before any SRS work on 2019 Civic.
Forward Camera Replacement
Camera module replacement requires full recalibration using HDS.
Any Front-End Collision
Inspect and recalibrate forward camera after any front-end collision using HDS.
Front Bumper Repair or Replacement
Forward radar angular alignment required after front bumper R&R. Use HDS.

FREQUENTLY ASKED QUESTIONS
FAQ
How much does ADAS calibration cost for a 2019 Honda Civic?
ADAS calibration pricing for a 2019 Honda Civic depends on which of its 3 documented systems need work after a repair. This vehicle is documented with Forward Camera (Monocular), Forward Radar (77GHz), and Honda Sensing Suite (EX+ trims). 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 2019 Honda Civic?
Yes. The 2019 Honda Civic 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: 77960-TBA-A060-M2. Mobile diagnosis and programming are the active service path. Mail-in bench intake is temporarily unavailable. 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 2019 Honda Civic?
After windshield replacement on a 2019 Honda Civic, Forward Camera (Monocular) and Forward Radar (77GHz) 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 intake is temporarily unavailable.
How long does a 2019 Honda Civic module service take?
Most 2019 Honda Civic onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 21 programmable modules documented in our database (4 ECU, 3 BCM, 1 TCU, 3 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 intake is temporarily unavailable.
Do you cover the 2019 Honda Civic on-site, or is this mail-in only?
We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, key programming, IMMO pairing, post-repair recoding, and supported module work). Mail-in module intake is temporarily unavailable. Quote the work and we will confirm the active service path for the 2019 Honda Civic. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2019 Honda Civic programming?
Every programming, cloning, and calibration job on the 2019 Honda Civic 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.
Can you program a 2019 Honda Civic with no working keys (all-keys-lost)?
Yes - all-keys-lost is supported on the 2019 Honda Civic. Immobilizer generation on this platform: Honda Immobilizer - EEPROM-based Smart Entry (10th Gen FC/FK). Adding a key (with a working key already in hand) is also supported - typically faster and less expensive than an all-keys-lost reset. Submit the VIN and we will confirm the procedure and quote before scheduling.
