WHAT WE RESOLVE
4th Gen XW50 (2016-2022) common module and ADAS issues
- ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. Documented systems include Forward Camera (verify by VIN) (2016-2018), Forward Radar (verify by VIN) (2016-2018), Blind Spot Monitor Sensor - Left (BSM) (2016-2018), and Blind Spot Monitor Sensor - Right (BSM) (2016-2018). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve SRS Control Unit (2016), SRS Control Unit (2016-2017), and SRS Control Unit (2017, 2019). 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.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Toyota Prius (2016-2022) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Toyota Prius (2016-2022). 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 Prius (2016-2022)?
The Toyota Prius (2016-2022) generation currently shows 85 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Control Unit (2016), SRS Control Unit (2016-2017), and SRS Control Unit (2017, 2019). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 89170-52K20 (2016) - confirm for your exact year/VIN.
Does Toyota Prius (2016-2022) need ADAS calibration after glass or collision work?
The merged generation data documents 26 ADAS systems, including Forward Camera (verify by VIN) (2016-2018), Forward Radar (verify by VIN) (2016-2018), Blind Spot Monitor Sensor - Left (BSM) (2016-2018), Blind Spot Monitor Sensor - Right (BSM) (2016-2018), and Rear Cross Traffic Alert (RCTA) (2016-2018). Calibration triggers include Windshield Replacement (2016-2018), Front Bumper Repair or Replacement (2016-2018), Rear Bumper Repair (2016-2018), and Any Collision (2016-2018). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on Toyota Prius (2016-2022)?
Yes. The generation data includes 19 SRS records, including SRS Control Unit (2016), SRS Control Unit (2016-2017), and SRS Control Unit (2017, 2019). 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: 89170-52K20 (2016) - confirm for your exact year/VIN.
Do all Toyota Prius (2016-2022) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2016-2022; 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 Prius (2016-2022)?
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.
