WHAT WE RESOLVE
X166 (2017-2019) common module and ADAS issues
- ADAS calibration drift Watch for calibration needs after windshield, bumper, suspension, camera, or radar work. Documented systems include PRE-SAFE Brake (Automatic Emergency Braking) (2017), Forward Camera (Monocular) - MFC (2017), Distronic Plus - Adaptive Cruise Control (ACC) (2017), and Active Lane Keep Assist / LDW (LKA/LDW) (2017). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve SRS Control Unit. 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.
- Gateway, key, and immobilizer access Gateway, key, and immobilizer procedures are represented by 11 merged security records. Access and all-keys-lost support varies by year - verify by VIN.
FREQUENTLY ASKED QUESTIONS
FAQ
Can you program Mercedes-Benz GLS (2017-2019) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz GLS (2017-2019). 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 Mercedes-Benz GLS (2017-2019)?
The Mercedes-Benz GLS (2017-2019) generation currently shows 12 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS examples include SRS Control Unit. Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: A222 900 02 03 - confirm for your exact year/VIN.
Does Mercedes-Benz GLS (2017-2019) need ADAS calibration after glass or collision work?
The merged generation data documents 19 ADAS systems, including PRE-SAFE Brake (Automatic Emergency Braking) (2017), Forward Camera (Monocular) - MFC (2017), Distronic Plus - Adaptive Cruise Control (ACC) (2017), Active Lane Keep Assist / LDW (LKA/LDW) (2017), and Blind Spot Assist / Rear Cross-Traffic Alert (2017). Calibration triggers include Windshield Replacement, Front Bumper Repair, Rear Bumper Repair, and Suspension Service (EABC). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on Mercedes-Benz GLS (2017-2019)?
Yes. The generation data includes 2 SRS records, including SRS Control Unit. 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: A222 900 02 03 - confirm for your exact year/VIN.
Do all Mercedes-Benz GLS (2017-2019) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2017-2019; 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.
Can you program keys or immobilizer systems for Mercedes-Benz GLS (2017-2019)?
Yes, where the VIN and security workflow support it. The generation data includes 11 gateway, immobilizer, or key-security records. Gateway examples include Central Gateway Module. Key records are present in the merged generation data. Security access, all-keys-lost eligibility, and add-key workflows vary by year - verify by VIN.
How long does service take for Mercedes-Benz GLS (2017-2019)?
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 work typically depends on module condition, donor data, and shipping window.
Is Mercedes-Benz GLS (2017-2019) service mobile or mail-in?
Both paths are available depending on the job. Mobile service covers DFW on-vehicle diagnostics, ADAS setup, key programming, and post-repair coding. Mail-in service covers ECU, BCM, SRS, TCU, ABS, and other bench module work nationwide. We confirm the correct path for your exact year/VIN before scheduling.
