Tools we use for this vehicle
Factory scan, coding, and calibration access
Toyota Techstream / Toyota GTS+
Factory routines and secure server authorization control this path when aftermarket coverage is not enough for the VIN.
ADAS scan, setup, and verification
Autel, Launch Tech, Topdon
Used where aftermarket coverage supports the procedure; OEM software remains required for locked factory routines.
Bench cloning and chip-level recovery
Alientech / Autotuner / Orange5 / Scanmatik / Flex / VVDI2 / PCMFlash / CGDI / X-Prog
Used only when the module, donor data, EEPROM, MCU, or crash-data workflow requires bench or chip-level handling.
Bench/chip-level only

FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Toyota bZ4X (2023-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Toyota bZ4X (2023-2026). The merged generation data includes ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS coverage. Rows marked with a year range apply only to that part of the span; unmarked rows are present across the merged generation data.
Which modules are documented for Toyota bZ4X (2023-2026)?
The Toyota bZ4X (2023-2026) generation currently shows 24 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Control Unit (2023) and SRS Control Unit (2024-2026). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 89170-42B60 (2023) - confirm for your exact year/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.
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 service is available nationwide. Exact service eligibility is confirmed from the year, VIN, module, and requested scope.
Is Toyota bZ4X (2023-2026) service mobile or mail-in?
Mobile service covers DFW on-vehicle diagnostics, post-repair coding, and supported module work. Mail-in module service is available nationwide. We confirm the active path for your exact year, VIN, module, and requested scope before service.
