WHEN IS CALIBRATION REQUIRED?

Triggers for ADAS recalibration

Windshield Replacement (Forward Camera Equipped)

HD-specific forward camera static cal via GDS2. Use HD WSM calibration procedure - chassis height differs from 1500. Level surface, forward target per HD WSM.

Forward Camera Replacement (HD)

GDS2 init + static cal using HD procedure. Inspect bracket. Confirm FCA/AEB.

Forward Radar Replacement (HD)

GDS2 HD radar alignment. Different calibration height than 1500. Level, 10 ft clear. Remove fascia before confirming.

BCM Replacement

SPS + VIN + all options (trailer brake type/weight, snowplow RPO if equipped, BSM, remote start, camera options) + PASS-Key relearn all keys.

ECM Replacement - L8T Gas

SPS + VIN + PASS-Key transfer + idle/throttle relearn.

ECM Replacement - L5P Duramax Diesel

SPS + VIN + PASS-Key transfer + DPF adaptation reset + injector trim codes + DEF system initialization via GDS2. Extended SPS time required.

DEF System Component Service (L5P)

!!MANDATORY!!: GDS2 DEF system initialization after any DEF pump, DEF injector, DEF tank, NOx sensor, or SCR catalyst service. Failure to initialize = engine derate. Verify DEF fluid quality (ISO 22241) before completing service.

EBCM Replacement (HD)

GDS2 ABS/ESC init + full 4-wheel brake bleed + SAS zero-point. Critical at HD GVWR 10,000+ lbs - must verify at operating load.

Wheel Alignment / Suspension Work

SAS zero-point calibration via GDS2 after ANY suspension height change. Drive straight 35+ mph. At HD GVWR this is a critical safety procedure - incorrect SAS affects towing stability and trailer brake assist.

Allison 10L1000 TCM Replacement (diesel)

GDS2 + Allison DOC or TIS2WEB Allison path. Allison quick learn. Verify Allison TES 295/668 fluid - do not use standard Dexron.

Trailer Brake Controller Configuration

GDS2 required - configure trailer brake type and weight class before any towing. User gain adjustment via IOR. Safety-critical at HD payload ratings.

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

Surround view mirror camera recalibration required after mirror R&R. Use GDS2/MDI2.

FREQUENTLY ASKED QUESTIONS

FAQ

How much does ADAS calibration cost for a 2020 Chevrolet Silverado-2500hd?

ADAS calibration pricing for a 2020 Chevrolet Silverado-2500hd depends on which of its 3 documented systems need work after a repair. This vehicle is documented with Forward camera / collision or lane camera - if equipped, Forward radar / adaptive cruise radar - if equipped, and Rear blind-zone, parking, rear camera, or surround-view sensors - if equipped. 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 2020 Chevrolet Silverado-2500hd?

Yes. The 2020 Chevrolet Silverado-2500hd 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: 84750512. 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 2020 Chevrolet Silverado-2500hd?

After windshield replacement on a 2020 Chevrolet Silverado-2500hd, Forward camera / collision or lane camera - if equipped, Forward radar / adaptive cruise radar - if equipped, and Rear blind-zone, parking, rear camera, or surround-view sensors - if equipped 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 2020 Chevrolet Silverado-2500hd module service take?

Most 2020 Chevrolet Silverado-2500hd onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 24 programmable modules documented in our database (2 ECU, 1 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 2020 Chevrolet Silverado-2500hd 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 2020 Chevrolet Silverado-2500hd. Do not ship a module unless support confirms next steps.

What kind of warranty do you offer on 2020 Chevrolet Silverado-2500hd programming?

Every programming, cloning, and calibration job on the 2020 Chevrolet Silverado-2500hd 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 2020 Chevrolet Silverado-2500hd with no working keys (all-keys-lost)?

Yes - all-keys-lost is supported on the 2020 Chevrolet Silverado-2500hd. Immobilizer generation on this platform: GM PASS-Key III+ (T1 HD Gen). 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 2020 Chevrolet Silverado-2500hd can you actually service?

We program, clone, repair, or replace the full programmable-module stack on a 2020 Chevrolet Silverado-2500hd. For this vehicle our database documents:

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

Infotainment on this platform: Chevrolet Infotainment 3. Send the VIN and the operations performed and we will confirm support and pricing.
