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: 89170-30 - confirm for your exact year/VIN.

Do all Toyota Crown Signia (2025-2026) years use the same parts?

No assumption should be made across the full span. The generation page merges rows across 2025-2026; 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 Crown Signia (2025-2026)?

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 Crown Signia (2025-2026) service mobile or mail-in?
