TOOL ACCESS MATRIX

Tools we use for this vehicle

We provide the software and equipment for the agreed work. The exact tool and procedure depend on your year, VIN and module.

Factory scan, coding, and calibration access

Mercedes XENTRY Diagnosis / Mercedes DAS

Factory routines and secure server authorization control this path when aftermarket coverage is not enough for the VIN.

ADAS scan, setup, and verification

Autel, Launch Tech, Topdon

Used where aftermarket coverage supports the procedure; OEM software remains required for locked factory routines.

Bench cloning and chip-level recovery

Alientech / Autotuner / Orange5 / Scanmatik / Flex / VVDI2 / PCMFlash / CGDI / X-Prog

Used only when the module, donor data, EEPROM, MCU, or crash-data workflow requires bench or chip-level handling.

Bench/chip-level only

Tool requirements

Basic OBD2 scanner

FREQUENTLY ASKED QUESTIONS

FAQ

Can you program Mercedes-Benz GLC (2023-2026) modules?

Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz GLC (2023-2026). 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 Mercedes-Benz GLC (2023-2026)?

The Mercedes-Benz GLC (2023-2026) generation currently shows 30 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS modules include SRS Control Unit. Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: A2059008600 - confirm for your exact year/VIN.

Does Mercedes-Benz GLC (2023-2026) need ADAS calibration after glass or collision work?

The merged generation data documents 12 ADAS systems, including Front Multi-Mode Camera (Active Distance Assist Distronic) (2023), Front Long-Range Radar (Distronic / ABA 5) (2023), Blind Spot Assist Plus / Rear Cross-Traffic Alert (2023), Front Corner Radars (Close-Range) (2023), and 360-Degree Camera System (Parking Package with 360 Camera) (2023). Calibration triggers include Windshield Replacement (2023), Front Bumper Repair (2023), Rear Bumper Repair (2023), and Mirror Replacement (2023). Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
