Cadillac XT4 1st Gen (2019-2025) ADAS Calibration & Module Programming
Covers model years 2019-2025 - one service guide for the whole generation.
Full ADAS calibration, module programming, and key security work for every Cadillac XT4 built on this platform. Same-day mobile service across the Dallas/Fort Worth metroplex; mail-in accepted nationwide.
- Platform GM VSS-S (Vehicle Set Segment-Small; compact crossover architecture)
- CAN Architecture HS-CAN (500 kbps); GM LAN / GMLAN; OBD2 DLC Pin 6/14
- Security GM PEPS (Passive Entry / Passive Start); rolling code transponder; GDS2 programmed
The ADAS, module, and security rows below are consolidated across the full 2019-2025 generation. A year badge marks rows that apply only to part of the span; rows without a badge apply to every year. Year-specific differences are summarized under “What changes across 2019-2025”.
OVERVIEW
Expert ADAS calibration, module programming, and diagnostic recovery for the 2022 Cadillac Xt4. On this vehicle we cover documented systems include Forward Camera (Mobileye EyeQ4) - AEB/FCW, Forward Radar (Bosch MRR) - Adaptive Cruise / AEB, and Blind Zone Alert - Left Rear Radar (Aptiv SRR), this GM VSS-S (Vehicle Set Segment-Small; compact crossover architecture) platform vehicle, GM PEPS Gen 2-3; BCM-based rolling immobilizer; SPS2 programming required immobilizer support, OEM-gateway-subscription work handled on our side.

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
GM GDS2 / GM Tech2Win / GM MDI 2
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 (2019-2025) 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) - AEB/FCW (2019), Forward Radar (Bosch MRR) - Adaptive Cruise / AEB (2019), Blind Zone Alert - Left Rear Radar (Aptiv SRR) (2019), and Blind Zone Alert - 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 Sensing & Diagnostic Module (SDM) (2019-2023), Sensing & Diagnostic Module (SDM) (2019-2022), and Sensing & Diagnostic Module (SDM). 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 Cadillac XT4 (2019-2025) modules?
Yes. Core Auto Logic supports generation-scoped module programming for the Cadillac XT4 (2019-2025). 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 Cadillac XT4 (2019-2025)?
The Cadillac XT4 (2019-2025) generation currently shows 19 core module records across ECU/PCM, BCM, TCU/TCM, ABS/EBCM, and SRS groups. SRS examples include Sensing & Diagnostic Module (SDM) (2019-2023), Sensing & Diagnostic Module (SDM) (2019-2022), and Sensing & Diagnostic Module (SDM). Part numbers and module variants must be confirmed for your exact year/VIN. Reference part number: 13523859 (2019-2023) - confirm for your exact year/VIN.
Does Cadillac XT4 (2019-2025) need ADAS calibration after glass or collision work?
The merged generation data documents 42 ADAS systems, including Forward Camera (Mobileye EyeQ4) - AEB/FCW (2019), Forward Radar (Bosch MRR) - Adaptive Cruise / AEB (2019), Blind Zone Alert - Left Rear Radar (Aptiv SRR) (2019), Blind Zone Alert - Right Rear Radar (Aptiv SRR) (2019), and Rear View Camera (RVC) (2019). Calibration triggers include Windshield Replacement, Front Bumper / Radar Removal, BCM Replacement, and ABS Module Replacement. Procedure type is VIN-specific scan-tool procedure; verify exact requirements by VIN before setup.
Can you reset the airbag module on Cadillac XT4 (2019-2025)?
Yes. The generation data includes 9 SRS records, including Sensing & Diagnostic Module (SDM) (2019-2023), Sensing & Diagnostic Module (SDM) (2019-2022), and Sensing & Diagnostic Module (SDM). 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: 13523859 (2019-2023) - confirm for your exact year/VIN.
Do all Cadillac XT4 (2019-2025) years use the same parts?
No assumption should be made across the full span. The generation page merges rows across 2019-2025; 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 Cadillac XT4 (2019-2025)?
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 Cadillac XT4 (2019-2025)?
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 Cadillac XT4 (2019-2025) 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.
