FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Kia Optima (2016-2020) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Kia Optima (2016-2020). The merged generation data includes ECU/PCM and TCU/TCM 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 Kia Optima (2016-2020)?
The Kia Optima (2016-2020) generation currently shows 10 core module records across ECU/PCM and TCU/TCM groups. Part numbers and module variants must be confirmed for your exact year/VIN.
Does Kia Optima (2016-2020) need ADAS calibration after glass or collision work?
ADAS availability varies by trim and year. Calibration need depends on equipped sensors and repair event. Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on Kia Optima (2016-2020)?
Yes. SRS crash-data service is confirmed from the part number and VIN. 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.
Do all Kia Optima (2016-2020) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2016-2020; 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 Kia Optima (2016-2020)?
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 Kia Optima (2016-2020) service mobile or mail-in?
