What Is ADAS Calibration? A Guide for Collision and Glass Techs

ADAS stands for advanced driver assistance systems: the electronics that watch the road around a vehicle and assist the driver.

For a collision or glass tech, the hardware sorts into sensor families, and the system groups ASE's L4 ADAS Specialist test names are one way the trade organizes them: camera-based systems, radar-based systems and ultrasonic (sonar) systems, plus a general ADAS service-and-diagnosis section.

• Cameras and front radar — the forward pair I-CAR trains together in its Calibration of Front Facing Cameras and Front Radar course.
• Ultrasonic sensors — the (sonar) group ASE's L4 breakdown tests as its own section.
• Lidar — the light-based sensing family, and the one system group the ASE L4 breakdown does not name.

Why the hardware lands in the shop: I-CAR describes these as systems that "now come standard in most new vehicles" and "must be properly repaired and calibrated after a collision."

The glass connection shows in I-CAR's catalog too: Windshields and ADAS is a course of its own.

Calibration is the automaker-directed process of checking and adjusting those sensors to the OEM's calibration requirements for that specific vehicle — not to a generic setting.

The requirements are looked up per vehicle: I-CAR's Repairability Technical Support (RTS) site lets a tech select year, make and model to pull OEM calibration requirements, OEM partial part replacement and restraint system results, OEM hybrid and EV disable procedures, and vehicle-maker position statements.

Locating the right procedure is a step with its own training: I-CAR dedicates an online course to Understanding OEM Calibration Procedures and How to Locate Them.

ASE treats calibration as its own skill area too — its L4 test description covers the skills required to "diagnose, service, and calibrate" advanced driver assistance systems.

"ADAS recalibration" is the same process re-run: the tech repeats it when repair work disturbs a system that had already been calibrated — the next section takes up what triggers it.

Calibration is not the repair itself.

It is a separate step with its own named work: I-CAR lists Post Repair ADAS Testing as a standalone online course.

The trigger list lives in the automaker's requirements, not the bench: the OEM's service information and I-CAR's RTS lookup define, per year, make and model, which repairs carry calibration for that vehicle.

Collision repair is the trigger I-CAR names outright: its ADAS page says these systems "must be properly repaired and calibrated after a collision."

Glass work sits close to the subject: I-CAR's online catalog pairs the two in a Windshields and ADAS course.

Automakers also publish their own positions.

GM has a January 2023 windshield-replacement position statement, and GM's Service Technical College recommends the Stationary Glass Removal and Installation course for technicians doing fixed-glass repairs.

Position statements are part of the lookup — RTS can access vehicle-maker position statements — so the habit is to check the requirements and the automaker's statements for the specific year, make and model before the glass comes out.

Verification runs after the repair on the same discipline: I-CAR lists Post Repair ADAS Testing as its own online course.

What falls in scope beyond that is the procedure's call for the vehicle in the bay — the lookup above is where a shop checks it before the work is scheduled.

Repair information carries the split by name: Mitchell's collision-repairer menu lists Scan & Dynamic Calibrations and Static Calibrations as separate solutions.

Static is the vehicle-stationary mode the name describes, run in the bay.

I-CAR treats the static side as a hands-on discipline: its Static ADAS Calibration course runs 3 days (24h).

Dynamic is the drive mode: the calibration runs while the vehicle is operated, under whatever conditions the automaker's procedure sets out.

Equipment follows the mode.

I-CAR's online catalog includes tool-specific courses on the AUTEL MaxiSys diagnostic tablet with its calibration kit (45m) and on the Bosch scan tool with an ADAS calibration kit (1h).

Which mode a vehicle needs is the OEM procedure's call, checked per year, make and model before the work is scheduled.

Calibration has its own role in the trade.

I-CAR lists ADAS Technician among the learning paths on its technician page, and among the nine individual roles on its Platinum path.

How that role works day to day — the settings, employers and training routes behind it — is its own topic, covered in the ADAS technician career guide.

I-CAR calls ADAS one of the fastest-growing specialties in collision repair — the training body's own characterization, not a government statistic.

On the service side, ASE offers an L4 Advanced Driver Assistance Systems (ADAS) Specialist test covering diagnosing, servicing and calibrating ADAS on automobiles, SUVs and light-duty trucks; it was listed on ASE's site as of October 2026.

ASE calls its certification voluntary — an industry credential, not a state license.

The requirements that shape who calibrates come from the programs a shop joins.

For 2026 renewals, an I-CAR Gold Class shop that performs ADAS calibrations in-house must list an ADAS Technician on its roster, who must complete ProLevel 1 and 2 and keep progressing toward Platinum by 2027.

I-CAR is also folding enhanced online ADAS ProLevel courses for its estimator, non-structural, structural and refinish roles into 2027 Gold Class achievement and renewal requirements.

Sending the work out does not remove the training expectation: Gold Class requires location-level foundational training, ADAS among it, that one or more roster technicians complete even when the shop sublets the work.

OEM networks add their own layer: Ford's Certified Collision Network requires a separate ADAS certification, with at least one technician per location completing a list of online ADAS courses plus a two-day hands-on course.

In the two-day hands-on course, technicians work in Ford Service Information (PTS) and the Ford Diagnostic & Repair System (FDRS) to identify, diagnose and repair ADAS on Ford vehicles.

Read together, the responsibility for the work is carried by three things: the automaker's procedure defines what a correct calibration is, the employer decides whether it is done in-house or sublet, and the training programs define who on the roster must be qualified for it.

What this page does not do is rule on liability.

How responsibility is assigned when a calibration is questioned is a legal and insurance question a career guide cannot settle — shops weighing that side take it to counsel, their insurer and the programs they operate under.

For estimators, calibration is a lookup question answered from the OEM's requirements: RTS pulls them per year, make and model, and platforms like Mitchell name static and dynamic calibrations as separate solutions in the repairer menu.

For body and structural techs, the procedure is the planning document: whether the repairs on the estimate carry calibration requirements is confirmed from the OEM's requirements before the work is scheduled, and the work is planned with the procedure in view from teardown onward.

For glass techs, the working habit is the same: the calibration requirements and the automaker's position statements, such as GM's January 2023 windshield-replacement statement, are checked for each vehicle before the glass work starts.

For shops, the staffing question is now explicit: I-CAR's Gold Class roster rule for in-house calibration shops and Ford's network certification make ADAS training a planning decision rather than an afterthought.

For the trade as a whole, the direction shows in the training infrastructure: I-CAR trains calibration as its own role with an online and hands-on course catalog, ASE tests it as a specialty, and I-CAR describes it as one of collision repair's fastest-growing specialties.
