Tool access for this exact year
Representative tool access paths for this exact model year, gated by the vehicle data and source packet we currently trust.
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.
OEM subscription required Security gateway access required No practical workaround
Make-level OEM tool map plus exact-year gateway and ADAS fields.
ADAS scan, setup, and verification
Autel, Launch Tech, Topdon
Used where aftermarket coverage supports the procedure; OEM software remains required for locked factory routines.
Tool subscription required
Service-level scanner-vendor source packet plus exact-year ADAS records.
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.

WHAT WE RESOLVE
1st Gen X243 (2022-2026) 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 (Mobileye EyeQ4) - EQB MFA2, Forward Radar (77GHz) - Continental ARS (EQB), Blind Spot Monitor / Active BSD (Aptiv SRR, EQB), and Rear View Camera (EQB). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve Airbag Control Unit (ACU) (EQB MFA2) (2022-2025), Airbag Control Unit (ACU) (EQB MFA2) (2026), and SRS-ECU (2026). 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 EQB (2022-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz EQB (2022-2026). 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 EQB (2022-2026)?
The Mercedes-Benz EQB (2022-2026) generation currently shows 14 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups.
