FREQUENTLY ASKED QUESTIONS

FAQ

Which ADAS systems does the Toyota Bz4X have, and which require calibration after collision repair?

Toyota Bz4X uses Toyota Safety Sense 3.0: FCM, 77GHz forward radar, BSM/ RCTA radars L/R and PVM cameras if equipped. FCM, front radar, BSM and PVM require calibration. Techstream on e‑TNGA (CAN FD + Ethernet) needed.

Can you reset the airbag/SRS light on a Toyota Bz4X?

Yes. We diagnose and clear SRS faults, perform repairs or module resets using Techstream on the e‑TNGA network. OE‑grade tools finalize SRS relearn and verify airbags, pretensioners and seatbelt systems.

What's involved in programming a replacement ECU/PCM for the Toyota Bz4X?

Replacement module programming requires Techstream and OE‑grade tools on the e‑TNGA CAN FD + Ethernet network. VIN coding, immobilizer registration and drivetrain‑specific calibrations (FWD vs AWD dual‑motor) are performed.

Do you support all-keys-lost (AKL) on the Toyota Bz4X?

Yes. We follow an authorized locksmith workflow with proof of ownership, Techstream immobilizer procedures and OE‑grade tools to program new smart keys. FWD or AWD configuration and VIN coding are handled in‑process.

What's needed after windshield replacement on a Toyota Bz4X?

Windshield replacement typically requires TSS 3.0 Front Camera Module recalibration and possible PVM camera verification. We use Techstream for static/dynamic recalibration on the e‑TNGA (CAN FD + Ethernet) network.

Can you service a Toyota Bz4X on-site, mail-in, or both?

Both. Mobile service handles some calibrations, key work and diagnostics. Module programming, OTA validation and complex ADAS calibrations require our shop with OE‑grade tools and Techstream on the e‑TNGA network.
