What to find out before approving repairs
In the estimate for a car from the USA, replacing glass or body parts may be only part of the work. If the repair involves cameras or radars of driver assistance systems, it is necessary to determine the manufacturer's requirements for their testing and calibration. The result for the buyer is a list of necessary procedures, responsible service and clear confirmation of completion of work before receiving the car.
ADAS stands for Advanced Driver Assistance Systems. NHTSA distinguishes between features that warn of danger and features that intervene in driving, such as automatic braking. Similar household names do not guarantee the same capabilities. Check the vehicle manual for the availability of the required system and its limitations.
This is an educational material for planning inspections, not a do-it-yourself sensor adjustment manual. The cover is an editorial illustration of a repair, not a photograph of a completed WonderCar calibration.
What events need to be reported to the service?
Collect links to the auction announcement for the car, available photos before and after the repair, a list of replaced parts, and documents from the previous workshop. Separately indicate windshield replacement, removal of cameras or radars, repair of their mounting points, and restoration of bodywork power elements. These are grounds for checking the requirements, not a universal command to perform the same procedure on all cars.
American Honda's document "Aiming Driving Support Systems", version 12, August 2025, lists windshield removal or replacement, camera removal or replacement, and certain body repairs as among the setup requirements for the applicable cameras. Honda recommends that you check the general table with your specific model manual; the table does not cover all possible repairs.
For Honda, when camera or radar adjustment is required due to an accident, this document also requires checking the angles of all four wheels and correcting any deviations before calibration. However, it does not explicitly state that the systems must be calibrated after each wheel adjustment. These provisions cannot be transferred to other brands without their documentation.
Why resetting isn't the end
The Tesla Service Manual for the 2017-2023 Model 3 separately describes clearing calibration data, calibrating the cameras, and checking their installation angle. After changing the position of the external camera, including reinstalling it, the previous data is cleared; a calibration process is then required. For individual cameras, after replacement or reinstallation, the orientation is also checked according to the appropriate service procedure.
This is an example of why the answer "settings reset" is not specific enough. Ask the service to list the operations performed and the result of each. The instructions provided are for the Model 3 years indicated; they do not define the procedure for all Teslas or other cars. The necessary version of the instructions is selected by a specialist for a specific car.
Do not test automatic braking by intentionally approaching a person or obstacle. The procedure for control checks and the admissibility of movement after repair should be determined with the service according to the manufacturer's documentation.
What to write in the estimate and report
The list provided is an editorial template for a conversation with the workshop, not a universal technical regulation. Ask to separate diagnostics, repair of damage, necessary preparatory operations and calibration. If a certain work is not required, it is useful to get an explanation with a link to the applicable manual.
In the final report, ask to specify the car, date, contractor, list of operations and their results. Keep documents with personal data private. If the estimate does not include an estimate for the required procedure, mark it as an unspecified expense; it does not become free because there is no line.
- What systems and sensors are installed on this particular car?
- What completed or planned work creates the need for calibration?
- What manufacturer's instructions apply to the model, year, and equipment?
- Who will perform the procedures and are they included in the agreed assessment?
- What previous faults or damage need to be fixed?
- What document will confirm the implementation, result and unresolved issues?
How to use answers before buying
A hypothetical case study: The seller reports a windshield replacement but only provides an invoice for the glass. The buyer does not yet know whether the installed camera needs calibration and whether it has been completed. The next step is to check the requirements for this vehicle and obtain confirmation of the relevant work. This is a fictional situation, not a WonderCar case.
Before agreeing on the auction bid amount, determine which issues can be closed now and which remain for review. If a significant part of the inspection is unavailable, postpone the decision or consider another vehicle. A successful calibration is also not a substitute for body, brake, or airbag inspections.
Through the WonderCar application form, you can discuss vehicle selection and available inspections. Prepare an auction listing for the vehicle and a brief list of known repairs and missing certifications. This will help you formulate a pre-purchase appraisal.
