FREQUENTLY ASKED QUESTIONS
FAQ
How much does ADAS calibration cost for a 2018 GMC Sierra-3500hd?
ADAS calibration pricing for a 2018 GMC Sierra-3500hd depends on which of its ADAS systems need work after a repair. 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 2018 GMC Sierra-3500hd?
Yes. The 2018 GMC Sierra-3500hd 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. Mobile diagnosis and programming are available in DFW, and mail-in module service is available nationwide. 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 2018 GMC Sierra-3500hd?
After windshield replacement on a 2018 GMC Sierra-3500hd, the forward-facing ADAS camera typically requires recalibration before lane-keep, pre-collision, and adaptive-cruise systems return to operation. We perform the calibration on-site in the DFW Metroplex with OE target fixtures. Mail-in module service is available nationwide for eligible module work.
How long does a 2018 GMC Sierra-3500hd module service take?
Most 2018 GMC Sierra-3500hd onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 1 programmable modules documented in our database (1 ECU, 0 BCM, 0 TCU, 0 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 service is available nationwide.
Do you cover the 2018 GMC Sierra-3500hd on-site, or is this mail-in only?
We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, post-repair recoding, and supported module work). Mail-in module service is available nationwide. Quote the work and we will confirm the active service path for the 2018 GMC Sierra-3500hd. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2018 GMC Sierra-3500hd programming?
Every programming, cloning, and calibration job on the 2018 GMC Sierra-3500hd 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.
Which modules on a 2018 GMC Sierra-3500hd can you actually service?
We program, clone, repair, or replace the full programmable-module stack on a 2018 GMC Sierra-3500hd. For this vehicle our database documents:
