OEM procedure access
A real calibration shop pulls the manufacturer's published procedure for that exact year, make, and model — not a generic checklist. Ask which subscription or platform they use to access OEM service information.

How to choose an ADAS calibration shop in Springfield, IL
Advanced driver assistance systems are only as safe as the calibration behind them. Whether you are a driver who just had a windshield replaced or a body shop owner sublet-shopping a calibration, the wrong choice can leave a vehicle with cameras and radars pointing at the wrong piece of the world. This guide explains exactly what to ask, what to look for, and how to tell a shop that takes calibration seriously from one that is guessing.
Manufacturer-spec targets
Cameras and radars are aimed using brand-specific targets, distances, and lighting. Generic universal targets do not meet OEM tolerance. The shop should be able to name the target set they use for your vehicle.
Written documentation
Pre-scan, post-scan, target placement photos, and a calibration report should land in your inbox or your file before the keys come back. If a shop cannot produce paperwork, insurance cannot defend the repair.
What to ask any calibration shop before you book
Start with equipment. The right scan tool matters as much as the right target. Ask whether the shop uses OEM scan tools or OEM-licensed aftermarket platforms for your vehicle's brand, and whether the technician has bidirectional control of the modules they are calibrating. Next, ask about the bay itself. Static calibrations require a level floor, controlled lighting, and enough clear space behind and in front of the vehicle to set targets at exact distances — typically 15 to 30 feet of unobstructed length depending on the procedure. A shop calibrating in a crowded general repair stall is improvising. Ask about dynamic calibrations too: which roads they use, what speeds and weather the OEM requires, and how they confirm the drive-cycle completed successfully. Finally, ask what documentation you receive. A confident shop will tell you exactly which reports come with the job before you ever hand over the keys.
Red flags versus green flags
Red flags are easy to spot once you know them. A shop that skips the pre-scan or post-scan is flying blind — without those reports, no one can prove which fault codes existed before the work versus after. A shop that uses generic targets instead of the manufacturer-specified set is hoping tolerances are loose enough to forgive the difference; they usually are not. Phrases like "we'll figure it out," "the light will go off after you drive it," or "we don't really need the procedure for this one" mean the technician is guessing. No documentation, no photos, no calibration certificate? Walk away. Green flags look different. A good shop will cite the OEM procedure by name, explain why your vehicle needs static, dynamic, or both, and show you the target setup if you ask. They will talk through the pre-scan with you, identify which modules will be touched, and send a post-scan report confirming the codes cleared. They will not be defensive about questions — they will be relieved you asked.
Dealer, independent calibration shop, or glass shop?
Each option has tradeoffs, and the right answer depends on the vehicle and the job. Dealers have factory training and OEM tooling, which is a real advantage on newer or unusual platforms. The downside is scheduling — dealer calibration bays are often booked one to three weeks out — and pricing tends to be the highest in the market. A dedicated independent calibration shop can match dealer quality if it invests in OEM-licensed scan tools, brand-specific target sets, and ongoing technician training. The advantage is turnaround time, transparent pricing, and a workflow built around calibration rather than squeezed between oil changes. Glass shops that offer in-house calibration are convenient because the windshield and the camera aim happen in one visit, but quality varies widely. Some glass shops have invested seriously in calibration equipment; others treat it as a checkbox. If a glass shop is doing your calibration, apply the same questions in this guide before agreeing — convenience is not worth a camera aimed three degrees off.
