ADAS Calibration Prerequisite Verification Sheet

It covers the checks that must be true before an ADAS calibration starts: repair order and vehicle identification, OEM procedure review, required tools and targets, vehicle loading and ride height, tire pressure and fuel level, bay levelness, lighting, obstruction control, and target placement. It is meant to confirm readiness before the calibration process begins, not to document the calibration results themselves. If a prerequisite fails, the sheet also captures the deficiency and the corrective action taken.

Use it after the vehicle is repaired enough to support calibration and before any static or dynamic calibration setup begins. It is especially useful after suspension work, collision repairs affecting ride height, wheel alignment, steering component replacement, or any OEM procedure that depends on precise bay conditions. If the vehicle is still mid-repair or the OEM prerequisites have not been reviewed, this sheet should not be signed off yet.

A trained collision repair technician, ADAS specialist, or shop foreman should complete it, depending on how your shop assigns calibration responsibility. The person signing should understand the OEM procedure, know how to measure the bay and vehicle setup conditions, and be able to identify a deficiency that would invalidate the calibration. In many shops, a second reviewer or manager signs off on unresolved issues or exceptions.

No. This sheet is a prerequisite verification tool, not the OEM procedure itself. It is designed to confirm that the vehicle, equipment, and environment match the OEM requirements before the calibration begins. The technician should still review the OEM service information, because the exact tire pressure, fuel level, load condition, target distance, and bay requirements can vary by make, model, and calibration type.

Common misses include using the wrong target distance, skipping the OEM procedure review, calibrating on a floor that is not within tolerance, failing to correct tire pressure or ride height, and overlooking aftermarket modifications that affect sensor alignment. Shops also run into issues when the bay has reflective surfaces, poor lighting, or an alignment rack that is not approved for calibration use. This template forces those checks to be documented before the work proceeds.

Use it for every vehicle calibration job, not just occasionally. ADAS prerequisites can change from one vehicle to the next, and even the same model may require different setup conditions depending on the calibration type or OEM procedure revision. A per-job verification sheet also creates a clean record when a calibration must be delayed because a prerequisite was not met.

Yes. It should be customized with the OEM-specific measurements, special tools, scan tools, target types, and any required loaded condition or ride height criteria for the vehicles you service. Many shops also add fields for static versus dynamic calibration, lane camera versus radar calibration, and links to the exact OEM procedure or service information reference. The core structure stays the same, but the values and pass/fail criteria should match the vehicle being serviced.

An ad hoc checklist often misses one of the conditions that can invalidate the calibration, especially when multiple technicians or bays are involved. This template gives you a repeatable sequence, a place to document deficiencies and corrective actions, and a clear sign-off trail. That makes it easier to show that the calibration was started only after the required prerequisites were verified.
