WHAT WE RESOLVE

C117 (2014-2019) 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) (2014), Rear View Camera (2014), PRE-SAFE Brake (Automatic Emergency Braking) (2015-2018), and Forward Camera (Monocular) - MFC (2015-2018). 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 14 merged security records. Access and all-keys-lost support varies by year - verify by VIN.

FREQUENTLY ASKED QUESTIONS

FAQ

Can you program Mercedes-Benz CLA (2014-2019) modules?

Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz CLA (2014-2019). 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 CLA (2014-2019)?

The Mercedes-Benz CLA (2014-2019) generation currently shows 39 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: A1179001701 0285 012 554 - confirm for your exact year/VIN.

Does Mercedes-Benz CLA (2014-2019) need ADAS calibration after glass or collision work?

The merged generation data documents 14 ADAS systems, including PRE-SAFE Brake (Automatic Emergency Braking) (2014), Rear View Camera (2014), PRE-SAFE Brake (Automatic Emergency Braking) (2015-2018), Forward Camera (Monocular) - MFC (2015-2018), and Distronic Plus - Adaptive Cruise Control (ACC) (2015-2018). Calibration triggers include ECM/ME Replacement (2014), ABS/ESP Module Replacement (2014), Windshield Replacement (2015-2019), and Front Bumper Repair (2015-2019). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.

Can you reset the airbag module on Mercedes-Benz CLA (2014-2019)?

Yes. The generation data includes 18 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: A1179001701 0285 012 554 - confirm for your exact year/VIN.

Do all Mercedes-Benz CLA (2014-2019) years use the same parts?

No assumption should be made across the full span. The generation page merges rows across 2014-2019; 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 CLA (2014-2019)?

Yes, where the VIN and security workflow support it. The generation data includes 14 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 CLA (2014-2019)?

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 CLA (2014-2019) 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.
