Forward Radar Replacement Affected: Forward Radar, FCA, Adaptive Cruise

GDS2 radar alignment. Level surface, 10 ft clearance forward, no metallic obstructions in FOV. Remove bumper fascia before confirming alignment. Verify Adaptive Cruise and AEB DTC-free.

BZA Rear Radar Replacement (either side) Affected: BZA, RCTA

GDS2 BZA module initialization. Fixed mount - no physical aiming required. DTC clear via GDS2. Road verify BZA and RCTA function at 20+ mph.

BCM Replacement Affected: BCM, PASS-Key III+, Remote Start, BSM

SPS programming (TIS2WEB) + VIN tie + all vehicle options configuration + PASS-Key III+ key relearn with all keys present.

ECM Replacement Affected: ECM, PASS-Key III+, Throttle, AFM/DFM

Any Front-End Collision

Inspect and recalibrate forward camera after any front-end collision using GDS2/MDI2.

Front Bumper Repair or Replacement

Forward radar angular alignment required after front bumper R&R. Use GDS2/MDI2.

Rear Bumper Repair or Replacement

BSD radar alignment required after rear bumper R&R. Use GDS2/MDI2.

BSM Sensor Replacement

Blind spot monitoring sensor replacement requires calibration using GDS2/MDI2.

Mirror Replacement

If BSD sensor is mirror-integrated, recalibration required. Verify sensor location; use GDS2/MDI2 if applicable.

FREQUENTLY ASKED QUESTIONS

FAQ

How much does ADAS calibration cost for a 2019 GMC Sierra-1500?

ADAS calibration pricing for a 2019 GMC Sierra-1500 depends on which of its 5 documented systems need work after a repair. This vehicle is documented with Forward Camera (Monocular), Forward Radar (77GHz), Blind Spot Monitor Sensor - Left (BSM), Blind Spot Monitor Sensor - Right (BSM), and HD Rear Camera. 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 so the quote response can include a real number.

Can you reset the airbag light on a 2019 GMC Sierra-1500?

Yes. The 2019 GMC Sierra-1500 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: 84057079. Mobile diagnosis and programming are the active service path. Mail-in bench intake is temporarily unavailable. Send the part number and a description of what triggered the light, and we will provide a quote and scheduling window.

What is needed after replacing the windshield on a 2019 GMC Sierra-1500?

After windshield replacement on a 2019 GMC Sierra-1500, Forward Camera (Monocular), Forward Radar (77GHz), and HD Rear Camera rely on the forward-facing camera and require recalibration before the systems return to operation. We perform the calibration on-site in the DFW Metroplex with OE target fixtures. Mail-in intake is temporarily unavailable.

How long does a 2019 GMC Sierra-1500 module service take?

Most 2019 GMC Sierra-1500 onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 32 programmable modules documented in our database (5 ECU, 4 BCM, 2 TCU, 4 ABS, plus IPC/SAS/gateway/accessory). Mobile module work and ADAS calibration are scheduled in the DFW service area after quote review. Mail-in module intake is temporarily unavailable.

Do you cover the 2019 GMC Sierra-1500 on-site, or is this mail-in only?

We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, key programming, IMMO pairing, post-repair recoding, and supported module work). Mail-in module intake is temporarily unavailable. Quote the work and we will confirm the active service path for the 2019 GMC Sierra-1500. Do not ship a module unless support confirms next steps.

What kind of warranty do you offer on 2019 GMC Sierra-1500 programming?

Every programming, cloning, and calibration job on the 2019 GMC Sierra-1500 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.

Can you program a 2019 GMC Sierra-1500 with no working keys (all-keys-lost)?

Yes - all-keys-lost is supported on the 2019 GMC Sierra-1500. Immobilizer generation on this platform: GM PASS-Key III+ (T1XX Gen 3). Adding a key (with a working key already in hand) is also supported - typically faster and less expensive than an all-keys-lost reset. Submit the VIN and we will confirm the procedure and quote before scheduling.

Which modules on a 2019 GMC Sierra-1500 can you actually service?

We program, clone, repair, or replace the full programmable-module stack on a 2019 GMC Sierra-1500. For this vehicle our database documents:

5 engine control (ECU/PCM)
2 transmission control (TCU/TCM)
4 body control (BCM and related)
4 ABS / brake control (EBCM)
3 immobilizer / security
2 key & fob
2 instrument cluster (IPC)
2 steering angle sensor (SAS)
5 ADAS module

Infotainment on this platform: GMC IntelliLink. Send the VIN and the operations performed and we will confirm support and pricing.
