WHAT WE RESOLVE

1st Gen (2023-2026) common module and ADAS issues

  • ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. Documented systems include TSS 3.0 Front Camera Module (FCM) - bZ4X (2023), Forward Radar (77GHz) (2023), Blind Spot Monitor (BSM) / RCTA Radar - L/R (2023), and Panoramic View Monitor (PVM) Camera System (if equipped) (2023). Year-marked systems apply only to the shown range.
  • SRS crash-data and warning light SRS service can involve SRS Control Unit (2023) and SRS Control Unit (2024-2026). Part numbers and crash-data workflow are confirmed for the exact year/VIN.
  • Replacement module setup ECU/PCM replacement programming, BCM configuration, TCU/TCM cloning, ABS/EBCM setup are represented in the merged generation data. Rows with year ranges do not apply to every model year; verify by VIN.

Does Toyota bZ4X (2023-2026) need ADAS calibration after glass or collision work?

The merged generation data documents 8 ADAS systems, including TSS 3.0 Front Camera Module (FCM) - bZ4X (2023), Forward Radar (77GHz) (2023), Blind Spot Monitor (BSM) / RCTA Radar - L/R (2023), Panoramic View Monitor (PVM) Camera System (if equipped) (2023), and TSS 3.0 Front Camera Module (FCM) - bZ4X 2024 (2024-2026). Calibration triggers include Windshield Replacement (2023), Front Bumper Repair or Replacement (2023), Rear Bumper Repair or Replacement (2023), and Any 400V HV System Service (2023). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.

Can you reset the airbag module on Toyota bZ4X (2023-2026)?

Yes. The generation data includes 4 SRS records, including SRS Control Unit (2023) and SRS Control Unit (2024-2026). Bench reset, cloning, and replacement setup are handled after part-number review. Any SRS part number shown for this generation is planning data only - confirm for your exact year/VIN. Reference part number: 89170-42B60 (2023) - confirm for your exact year/VIN.

Do all Toyota bZ4X (2023-2026) years use the same parts?

No assumption should be made across the full span. The generation page merges rows across 2023-2026; any row that does not span all data-bearing years is printed with its year range or treated as varies by year - verify by VIN. Part numbers always require exact year/VIN confirmation before ordering, cloning, or programming.

Can you program keys or immobilizer systems for Toyota bZ4X (2023-2026)?

Yes, where the VIN and security workflow support it. The generation data includes 6 gateway, immobilizer, or key-security records. Key records are present in the merged generation data. Security access, all-keys-lost eligibility, and add-key workflows vary by year - verify by VIN.

How long does service take for Toyota bZ4X (2023-2026)?

Most programming, cloning, SRS, and calibration jobs are quoted after VIN, DTC, part number, and repair-scope review. Labor time varies by year - verify by VIN before scheduling. Mail-in module work typically depends on module condition, donor data, and shipping window.

Is Toyota bZ4X (2023-2026) service mobile or mail-in?

Both paths are available depending on the job. Mobile service covers DFW on-vehicle diagnostics, ADAS setup, key programming, and post-repair coding.
