Triggers for ADAS recalibration
Windshield Replacement
TSS-P forward camera static calibration required. Techstream: level surface, Toyota target board ~1m from vehicle front (Corolla WSM spec - NOT Camry 3.0m). Body-style specific camera: sedan 86790-02F50 / hatchback 86790-12R50. Android Auto added 2020 - verify head unit camera wiring integrity post-windshield.
Forward Camera (TSS-P) Replacement
Confirm body-style PN. Techstream initialization + static calibration per 2020 Corolla WSM. Verify all TSS-P DTC clear before road test.
Forward Radar Replacement
Confirm PN via TIS. Techstream boresight. Bumper fully reinstalled before final cal. Combined camera + radar DTC clear verify.

ABS HCU Replacement
Techstream ABS/VSC init + power bleed + SAS zero-point reset. 35+ mph straight run. Hybrid: HV disable first, regen braking verify after. Base PN 44510-02400 / Hybrid 44510-02420.
Smart Key ECU / BCM Replacement
TIS authorization. Max 4 keys Corolla. All customer keys present. Techstream Smart Key registration. Verify all keys start vehicle.
Airbag Work (Takata Recall - 2020 Corolla)
MANDATORY NHTSA VIN check before airbag work. Takata recall 2020 Corolla. 90-sec SRS disable. ACU 89170-02Y10 replace-only. Techstream SRS DTC clear after all SRS work.
Forward Camera Replacement
Camera module replacement requires full recalibration using Techstream.
Any Front-End Collision
Inspect and recalibrate forward camera after any front-end collision using Techstream.
Front Bumper Repair or Replacement
Forward radar angular alignment required after front bumper R&R. Use Techstream.
Rear Bumper Repair or Replacement
BSD radar alignment required after rear bumper R&R. Use Techstream.
Mirror Replacement
If BSD sensor is mirror-integrated, recalibration required. Verify sensor location; use Techstream if applicable.

FREQUENTLY ASKED QUESTIONS
FAQ
How much does ADAS calibration cost for a 2020 Toyota Corolla?
ADAS calibration pricing for a 2020 Toyota Corolla depends on which of its 5 documented systems need work after a repair. This vehicle is documented with Forward Camera (Monocular), Forward Radar (77GHz), Blind Spot Monitor Sensor - Left (BSM), and Blind Spot Monitor Sensor - Right (BSM). 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 2020 Toyota Corolla?
Yes. The 2020 Toyota Corolla 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: 89170-02N50. 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 2020 Toyota Corolla?
After windshield replacement on a 2020 Toyota Corolla, 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 2020 Toyota Corolla module service take?
Most 2020 Toyota Corolla 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 (5 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 2020 Toyota Corolla 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 2020 Toyota Corolla. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2020 Toyota Corolla programming?
Every programming, cloning, and calibration job on the 2020 Toyota Corolla 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 2020 Toyota Corolla with no working keys (all-keys-lost)?
Yes - all-keys-lost is supported on the 2020 Toyota Corolla. Immobilizer generation on this platform: Toyota Immobilizer IMMO3 (AES-128). 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.
