ADAS Calibration Documentation: What Your Record Should Show

Collision Auto Glass & Calibration
October 31, 2026

ADAS calibration documentation is the written record that a shop restored your driver-assistance sensors to the manufacturer’s specification after a repair. A solid record names the vehicle by VIN, lists the scans before and after, cites the OEM procedure that was followed, describes the calibration steps and the person who did them, and shows the result. If you leave a shop without it, you have no proof the work was done.

This guide covers who needs the paperwork (owners, fleet managers and insurers), which repairs trigger it, what a complete file contains, and how to ask for it. We are an auto glass and calibration shop in Portland, so we also explain how we think about it.

TL;DR

  • Windshield replacement, collision repair, suspension work, alignments and any repair touching a sensor or its bracket can require calibration, and each one should leave a record.
  • A complete file includes the valid VIN, pre- and post-repair scan printouts, the OEM procedure used, calibration steps, who performed them, and photo or video evidence.
  • Dynamic calibrations should also record the route, weather, speed and the moment the system confirmed success.
  • Ask for the record before you drive away. Some states, such as Virginia, already require glass shops to give written notice about calibration.
  • Keep your copy with your insurance claim and service history. It matters most in a dispute or a later warranty question.

Why the paperwork matters as much as the calibration

A camera that is aimed a degree or two off does not announce itself. Lane-keeping, automatic emergency braking and adaptive cruise may all look normal on the dash while being slightly wrong on the road. The record is how anyone, including you, later learns that the system was checked.

Technician writers say the same thing in plain terms. Hiran Alwis of ADAS Project describes documentation as proof of due diligence that protects a workshop from liability if a system malfunctions after a repair, not as bureaucratic overhead. Paul Bostel, writing in Fender Bender, notes that in the eyes of insurance and the law, “if it’s not documented, it didn’t happen” holds true.

For the vehicle owner, this works in three ways:

  1. Insurance claims. If a claim is questioned, a dated record shows what was done and to what standard.
  2. Resale and warranty. A manufacturer may question damage tied to unapproved parts or procedures. Lincoln’s collision repair position states that damage from unapproved parts or procedures may not be covered or warranted.
  3. Safety after an accident. If a system misbehaves later, a file tells the next technician what was already done.

For fleets, the same file becomes a per-vehicle audit trail. For insurance agents, it is the document that closes the loop on an authorized repair.

Which repairs call for a calibration record

The short answer is any repair that moves, replaces or disturbs a sensor, or changes the geometry the sensor relies on. A European best-practice paper on ADAS repair lists collisions, windshield replacements, suspension repairs, wheel alignments and any repair involving ADAS sensors or their mounting brackets as events needing calibration, and says the documentation proves the safety systems were restored to OEM specifications.

Manufacturers are specific about it. A few U.S. examples:

The common thread: the manufacturer decides what is required for your exact vehicle, and the record should show that decision was followed. I-CAR’s diagnostic best practice says access to current OEM repair information is required before any repair decisions, because it dictates the calibration and aiming requirements for ADAS parts.

If your repair was glass only, see our guide to calibration after windshield replacement. If it was a collision, read why to ask for scans before you drive. If the trigger was a software update, we cover calibration after a software update.

What to include in an auditable ADAS calibration record

An auditable record lets a person who was not in the bay reconstruct what happened. Industry workflow guidance says a report should include a valid VIN, DTC and module scan results, OEM procedures, calibration steps, personnel, and photo or video evidence. The same document says documentation must include a printout of all DTCs and modules tested, with the vehicle’s valid VIN.

Here is that list as a checklist you can hold a shop to:

Item What it should show Why it matters
Vehicle identity Full VIN, year, make, model, mileage at drop-off Ties the file to one car, not a similar one
Pre-repair scan All modules tested and any trouble codes found Shows the starting condition
Post-repair scan The same modules, with codes cleared or explained Shows the finishing condition
Repair event What was replaced or removed (windshield, camera, bumper, radar) Explains why calibration was needed
OEM procedure Which manufacturer procedure was followed, and static or dynamic Proves the right method, not a generic one
Calibration steps Targets or equipment used, setup, results per sensor Lets another technician verify the work
Personnel Who performed and who verified Accountability
Evidence Photos or video of setup, and the final pass screen Backs up the written entries
Date and release When the work was completed and when the car was handed over Sets the timeline for any later claim

A note on the trouble codes. I-CAR explains that DTCs do not identify the part to replace; they lead a qualified technician to the correct diagnostic test. A printout with codes and no explanation is a starting point, not a conclusion. Look for a short note on what was found and what was done about it.

Static and dynamic calibration entries

Static calibration happens in the shop with targets placed at measured distances. Dynamic calibration needs a road drive under set conditions. Each leaves a different trail.

For dynamic calibrations, ADAS Project recommends documentation that records the route, weather and speed, and when the system confirmed successful calibration. Without those entries, “dynamic calibration complete” is just a phrase.

Static and dynamic calibration record entries

If the drive is done by someone outside the shop, the repair facility should have an agreement with the test-drive personnel and receive documentation showing the test was completed correctly, according to the same workflow guidance.

How a shop should verify success before release

A scan with no codes is not the same as a verified calibration. Thatcham Research’s repair position says repairers should use a competent technician and retain certified evidence that affected sensors function within manufacturer tolerances. It adds that if OEM instructions require dynamic calibration, the shop should confirm it before the vehicle is released.

Thatcham is a U.K. body, so treat it as a sound benchmark rather than a U.S. legal rule. The principle carries over: verification is a step with its own evidence, not an assumption.

In practice, ask three questions at pickup:

  1. Did the final scan show the calibration as complete for each affected sensor?
  2. Was the manufacturer’s procedure for my exact vehicle followed?
  3. Can I have the report, with the scans and the evidence, today?

A confident shop answers all three without hesitation.

Who gets the record, and how long to keep it

The owner or work provider should be able to get it. Thatcham’s position says documentation should be shared with the asset owner or work provider if requested, with records kept in line with standards such as BS10125. That is a U.K. standard, so U.S. retention periods depend on your state, your insurer and your own needs.

In the U.S., rules are beginning to put this in statute. Virginia’s 2026 Code requires glass shops to tell customers whether manufacturer-recommended calibration is needed and, if it was performed, to give written notice of whether it was successful. That rule applies in Virginia only, but it shows where expectations are heading. We recommend you ask for written confirmation wherever you are.

A practical retention guide for each audience:

  • Vehicle owners: keep the report with your insurance claim paperwork for as long as you own the car, and hand a copy to the buyer when you sell.
  • Fleet managers: file by VIN and unit number so a vehicle’s calibration history follows it through its service life.
  • Insurance agents: attach the record to the claim file so the authorization and the proof of completion sit together.

One point on insurance. If your claim is handled by your provider without shop selection, you may not choose the shop, but you can still request the report from whoever does the work.

Our perspective: calibration is not finished until it is documented

We see ADAS calibration as the last step of a glass or collision job, not an add-on. A new windshield can be installed perfectly and still leave the forward camera looking at the world at the wrong angle. That is why we do calibration in-house, with our certified local team, rather than sending customers elsewhere and hoping the loop closes.

Our view on records is simple. The calibration has to be done to the manufacturer’s procedure for that vehicle, and the owner should be able to see what was done. A record is part of the repair, in the same way the urethane adhesive and the glass are. When the work and the paper agree, you can drive away with confidence, and an insurer or fleet auditor can see why.

That sits alongside the rest of how we work: same-day service, free mobile installation within the Portland area, direct insurance billing and a lifetime no-leak guarantee on our installations. We have been family-owned and operated since 2008, and we would rather you ask hard questions about calibration than assume it was handled.

A pickup checklist you can use anywhere

Whether you use us or another shop, take this list with you:

  • Confirm the shop has the current OEM repair information for your VIN before work starts.
  • Ask whether your repair event, such as a windshield, bumper, alignment or camera removal, triggers calibration under the manufacturer’s procedure.
  • Request pre- and post-repair scans and check that the VIN on the printout matches your car.
  • Look for the procedure type (static, dynamic or both) and, for a road drive, the route, weather and speed.
  • Ask who performed the calibration and who verified it.
  • Request photos or video of the setup and final result.
  • Get everything in writing or by email before you leave, and store it with your claim.

If a shop says no calibration is needed, ask for the manufacturer’s statement for your model. Skipping it without a reason is a risk to you, not to them. We explain what is at stake in what happens if ADAS is not calibrated.

Common mistakes with calibration paperwork

Accepting a generic receipt. An invoice line reading “ADAS calibration” proves a charge, not a procedure. The record should show scans and steps.

Missing the VIN match. A report for the wrong vehicle, or with no valid VIN, cannot support a claim.

Forgetting the trigger event. If the file does not say why calibration was needed, a later reader may not connect it to the repair.

Losing the file. Photograph the report and email it to yourself the day you get it.

Assuming the insurer has it. Insurers receive what the shop submits. Keep your own copy.

FAQ

What is ADAS calibration documentation?

It is the written record of a calibration: the vehicle’s VIN, scans, the OEM procedure followed, the steps, the technician and the results. It proves the sensors were set to manufacturer specification after a repair. It also helps in insurance disputes and warranty questions.

Am I entitled to a copy of the calibration report?

You can always ask, and a reputable shop will provide one. Some states put it in law: Virginia requires glass shops to give written notice about calibration and its success. Check your state’s rules and ask in writing before the work begins.

Does a windshield replacement need a calibration record?

If your vehicle has a camera mounted behind the windshield, the manufacturer’s procedures may require calibration after replacement, and the record shows it was done. Windshield replacement is among the events European best-practice guidance lists as needing calibration. Your OEM repair information confirms the requirement for your model.

How long should I keep ADAS calibration paperwork?

There is no single U.S. rule we can point to. We suggest keeping it for as long as you own the vehicle and passing a copy to the next owner. Fleets should keep it by VIN for the vehicle’s service life.

What should a dynamic calibration record include?

Beyond the standard items, it should record the route, weather and speed, and when the system confirmed that calibration succeeded. Without those details, the entry cannot be verified later.
