WHAT WE RESOLVE
5th Gen RL6 (2018-2026) 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 (Monocular) (2018), Forward Radar (77GHz) (2018), Adaptive Cruise Control (ACC) (2018), and Lane Keep Assist / Lane Departure Warning (LKA/LDW) (2018). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve SRS Control Unit (2018-2023), SRS Control Unit (2022), and SRS Control Unit (2023). 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 Honda Odyssey (2018-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Honda Odyssey (2018-2026). 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 Honda Odyssey (2018-2026)?
The Honda Odyssey (2018-2026) generation currently shows 40 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Control Unit (2018-2023), SRS Control Unit (2022), and SRS Control Unit (2023). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 77960-THR-A020-M2 (2018-2023) - confirm for your exact year/VIN.
Does Honda Odyssey (2018-2026) need ADAS calibration after glass or collision work?
The merged generation data documents 19 ADAS systems, including Forward Camera (Monocular) (2018), Forward Radar (77GHz) (2018), Adaptive Cruise Control (ACC) (2018), Lane Keep Assist / Lane Departure Warning (LKA/LDW) (2018), and Rear View Camera (2018). Calibration triggers include Windshield Replacement (2018), Front Bumper Repair or Replacement (2018), Rear Bumper or Liftgate Repair (2018), and Front or Side Collision (2018). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on Honda Odyssey (2018-2026)?
Yes. The generation data includes 7 SRS records, including SRS Control Unit (2018-2023), SRS Control Unit (2022), and SRS Control Unit (2023). 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: 77960-THR-A020-M2 (2018-2023) - confirm for your exact year/VIN.
Do all Honda Odyssey (2018-2026) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2018-2026; 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 Honda Odyssey (2018-2026)?
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 Honda Odyssey (2018-2026) service mobile or mail-in?
