Triggers for ADAS recalibration
Windshield Replacement
TSS-P 2.0 forward camera static calibration required. CRITICAL: use 2020-2021 target chart (3.0m distance specification) - do NOT use 2022+ TSS 2.5 target specs. Techstream calibration menu: vehicle on level surface, Toyota target board at 3.0m ± 0.05m from vehicle front center. No objects in forward 3m zone. Horizontal target alignment within 5mm of center. ~2 min via Techstream. Verify camera DTC clear after calibration.
Forward Camera (TSS) Replacement
Same as windshield procedure. Techstream camera initialization + static calibration. Confirm correct PN: ~86790-0E240 (TSS 2.0 XU70) - NOT 86790-0E270 (TSS 2.5, 2022+). Verify all TSS-P 2.0 DTC clear.
Forward Radar Replacement
Techstream radar initialization. Calibration performed in conjunction with camera static calibration. Confirm correct radar PN: ~88210-0E060 (gas) or ~88210-42100 (hybrid). No physical aiming mechanism - replacement and Techstream init only.
BSM Sensor Replacement (either side)
Techstream BSM sensor initialization after replacement. Rear bumper corner fixed mount - no physical aiming adjustment. Verify BSM and RCTA DTC clear. Road verify at 20+ mph with adjacent vehicle.
Skid Control ECU Replacement
Techstream ABS/VSC initialization + steering angle sensor (SAS) zero-point calibration. Drive straight on level surface at 35+ mph for SAS self-calibration to complete. Verify no VSC/ABS DTC post-procedure. Hybrid: verify regenerative braking integration.
ECM Replacement (Gas or Hybrid)
Techstream ECM programming (TIS calibration file) + VIN registration + IMMO coding + injector compensation data entry (QR on each injector) + throttle body zero-point cal. Hybrid: HV service plug removal required before ECM work. Coordinate HV Battery ECU and MG ECU after hybrid ECM replacement.
Smart Key ECU / Body ECU Replacement
TIS dealer authorization required. All customer keys must be physically present. Techstream Smart Key registration procedure. Verify all keys start vehicle and all Smart Entry functions (push-start, door lock/unlock range) operate correctly after completion.
Wheel Alignment / Steering Component R&R
Techstream steering angle sensor zero-point reset. Drive straight at 35+ mph on level road to complete SAS learning cycle. VSC warning lamp will remain until SAS calibration completes. Verify no VSC DTC after drive cycle.
HV Battery ECU or MG ECU Replacement (Hybrid)
Mandatory: remove HV service plug before any HV ECU work. Techstream HV ECU programming (TIS file). Verify HV cell balance and SOC after HV Battery ECU replacement. Resolver calibration for MG ECU via Techstream. Confirm no HV DTC and Ready lamp operates normally before return to customer.
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 Highlander?
ADAS calibration pricing for a 2020 Toyota Highlander depends on which of its 7 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 Cross Traffic Alert (RCTA). 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 Highlander?
Yes. The 2020 Toyota Highlander 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: 89170-0E230. 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 Highlander?
After windshield replacement on a 2020 Toyota Highlander, 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 Highlander module service take?
Most 2020 Toyota Highlander onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 28 programmable modules documented in our database (7 ECU, 4 BCM, 1 TCU, 6 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 Highlander 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 Highlander. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2020 Toyota Highlander programming?
Every programming, cloning, and calibration job on the 2020 Toyota Highlander 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 Highlander with no working keys (all-keys-lost)?
Yes - all-keys-lost is supported on the 2020 Toyota Highlander. Immobilizer generation on this platform: Toyota Immobilizer Gen 4 (AES-128 DST-AES). 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.
