WHAT WE RESOLVE
2nd Gen W463 (W463A) (2019-2026) 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) (2019), Forward Radar (Continental ARS) (2019), Blind Spot Monitor - Left Rear Radar (Aptiv SRR) (2019), and Blind Spot Monitor - Right Rear Radar (Aptiv SRR) (2019). Year-marked systems apply only to the shown range.
- SRS crash-data and warning light SRS service can involve Airbag Control Unit (ACU / N2/7) (2019), Driver Airbag Module (Steering Wheel) (2019-2022), and SRS Module (2019-2022). 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 G-Class (2019-2026) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Mercedes-Benz G-Class (2019-2026). 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 G-Class (2019-2026)?
The Mercedes-Benz G-Class (2019-2026) generation currently shows 38 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS examples include Airbag Control Unit (ACU / N2/7) (2019), Driver Airbag Module (Steering Wheel) (2019-2022), and SRS Module (2019-2022).
