ADAS calibration pricing for a 2021 Cadillac Ct4 depends on which of its 6 documented systems need work after a repair. This vehicle is documented with Forward Camera (Mobileye EyeQ4) - AEB/FCW, Forward Radar (Bosch MRR) - Adaptive Cruise / AEB, Blind Zone Alert - Left Rear Radar (Aptiv SRR), Blind Zone Alert - Right Rear Radar (Aptiv SRR), and Rear View Camera (RVC). We provide a fixed quote after confirming the operations performed - send the VIN, the repair scope (windshield R&R, bumper work, alignment, collision), and any DTCs and we return a number within 4 hours.
Yes. The 2021 Cadillac Ct4 uses a factory SRS control module that we support. We read and clear stored crash data, then restore the module to factory status so the airbag warning light goes out and the system returns to full operation. Reference part number on this vehicle: 13542692. Bench-only or in-vehicle - both paths are supported. Send the part number and a description of what triggered the light, and we will provide a quote and ETA.
After windshield replacement on a 2021 Cadillac Ct4, Forward Camera (Mobileye EyeQ4) - AEB/FCW, Forward Radar (Bosch MRR) - Adaptive Cruise / AEB, and Rear View Camera (RVC) rely on the forward-facing camera and require recalibration before the systems return to operation. We perform the calibration on-site (DFW Metroplex) with OE target fixtures or via mail-in for the front camera/radar module.
Most 2021 Cadillac Ct4 jobs complete same-day once the vehicle or module arrives. This vehicle has roughly 22 programmable modules documented in our database (3 ECU, 1 BCM, 2 TCU, 1 ABS, plus IPC/SAS/gateway/accessory). Module-bench work (ECU clones, BCM reprograms, SRS resets) ships back inside 1-3 business days including return shipping. ADAS calibration is on-site for DFW or mail-in for the front module.
Both. We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, key programming, IMMO pairing, post-repair recoding) and a mail-in bench for module-only jobs (ECU cloning, BCM repair, SRS reset, TCU clone). Quote the work and we will tell you which path is right for the 2021 Cadillac Ct4.
Every programming, cloning, and calibration job on the 2021 Cadillac Ct4 is backed by a workmanship warranty covering the scope of work we performed: 1-year unlimited on all flashes, clones, and ADAS calibrations. If a module we programmed or a calibration we performed fails to function as expected, return it and we restore it at no charge. The warranty covers our work; it does not cover unrelated mechanical or electrical failure of the module itself.
Yes, our key programming specialists handle all-keys-lost scenarios on the 2021 Cadillac Ct4. Immobilizer generation on this platform: GM PEPS Gen 2-3; BCM-based rolling immobilizer; SPS2 programming required. Submit the VIN and we will confirm the procedure and quote before scheduling.
