Triggers for ADAS recalibration
Windshield Replacement (Forward Camera Equipped)
GDS2 HD camera static calibration. HD chassis height - use HD WSM procedure, NOT light-duty 1500 procedure. Level surface, target chart at HD-specified distance and height.
Forward Camera Replacement (HD)
GDS2 HD initialization + static calibration. Inspect bracket. Confirm FCA and AEB operational.
Forward Radar Replacement (HD)
GDS2 HD radar alignment. Level surface, 10 ft front clearance. Remove fascia before confirming alignment. HD calibration values only.
BCM Replacement
SPS + VIN + trailer brake type/weight + snowplow RPO (if equipped) + all options (BSM, remote start, Rear Ped Alert, surround vision) + PASS-Key III+ relearn ALL customer keys.
ECM Replacement - L8T Gas
SPS via TIS2WEB + VIN + PASS-Key parameter transfer + idle/throttle relearn.
ECM Replacement - L5P Duramax Diesel
SPS via TIS2WEB + VIN + PASS-Key + DPF adaptation reset + injector trim codes via GDS2 + DEF system initialization. Extended programming time. Do not return vehicle with active aftertreatment DTCs.
DEF System Component Service - L5P (ANY component)
!!MANDATORY - NO EXCEPTIONS!!: GDS2 DEF system initialization required after service to DEF pump, DEF injector, DEF tank, NOx sensor (either), or SCR catalyst. Failure = engine derate. Verify ISO 22241 DEF fluid quality before completing service. Contaminated DEF requires immediate correction - do not allow customer to drive with contaminated DEF.
EBCM Replacement (HD)
GDS2 ABS/ESC initialization + 4-wheel pressure brake bleed + SAS zero-point calibration. Drive straight 35+ mph on level surface before any towing or GVWR-rated load.
Wheel Alignment / Suspension Work
SAS zero-point calibration via GDS2 mandatory after any suspension height change. Drive 35+ mph straight. At 10,000+ lbs GVWR, incorrect SAS directly compromises towing stability and trailer brake assist effectiveness.
Allison 10L1000 TCM Replacement (L5P diesel)
Allison DOC or TIS2WEB Allison programming path. Allison quick learn procedure. Verify Allison TES 295 or TES 668 approved fluid is in use - do NOT use standard Dexron in 10L1000.
Trailer Brake Controller Configuration (after BCM R&R or new trailer)
GDS2 mandatory configuration: trailer brake type and weight class. IOR gain adjustment. Verify operation with connected trailer before releasing vehicle. Safety-critical at HD GVWR.
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 2025 Chevrolet Silverado-2500hd?
ADAS calibration pricing for a 2025 Chevrolet Silverado-2500hd depends on which of its 8 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 Surround Vision (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 2025 Chevrolet Silverado-2500hd?
Yes. The 2025 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: 85133043. 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 2025 Chevrolet Silverado-2500hd?
After windshield replacement on a 2025 Chevrolet Silverado-2500hd, 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 2025 Chevrolet Silverado-2500hd module service take?
Most 2025 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 33 programmable modules documented in our database (6 ECU, 3 BCM, 2 TCU, 6 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 2025 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 2025 Chevrolet Silverado-2500hd. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2025 Chevrolet Silverado-2500hd programming?
Every programming, cloning, and calibration job on the 2025 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 2025 Chevrolet Silverado-2500hd with no working keys (all-keys-lost)?
Yes - all-keys-lost is supported on the 2025 Chevrolet Silverado-2500hd. Immobilizer generation on this platform: PK3/PK3+ / PEPS.
