ADAS Calibrations
Driver-assistance technology depends on accurate reference points. After certain repairs or component changes, cameras and radar sensors may require calibration according to the vehicle manufacturer’s procedures.
Discuss Your Calibration RequirementsWhat is ADAS calibration?
ADAS stands for Advanced Driver Assistance Systems. Calibration establishes specified reference relationships for supported cameras, radar sensors, or other equipment so the system can interpret information as intended.
The procedure depends on the vehicle, its equipment, and the work performed. A successful calibration is one part of completing the applicable repair and verification requirements.
Static, dynamic, or a combination.
The manufacturer determines which method applies. These procedures are not interchangeable.
Static calibration
Performed with the vehicle stationary using specified equipment and, where required, targets or reflectors. Setup dimensions and environmental conditions must meet the applicable instructions.
Dynamic calibration
Requires operating the vehicle under prescribed conditions while the calibration process runs. Road markings, speed, visibility, and other conditions may affect completion.
Combined procedures
Some vehicles or systems require multiple stages. A stationary procedure may be followed by a driving procedure or additional verification steps.
Repairs may affect sensor relationships.
Calibration requirements should be checked whenever work could affect a sensor, its mounting position, or the vehicle geometry used by the system.
A warning light is not the deciding factor. A manufacturer may require calibration after a specified repair even when the dashboard shows no warning.
Events that may trigger a procedure review
- Replacement or removal of a windshield-mounted camera.
- Windshield replacement on vehicles with related equipment.
- Repair or replacement near radar sensors and mounting brackets.
- Collision repairs affecting specified body or structural areas.
- Certain alignment, suspension, or ride-height changes.
- Relevant sensor replacement, fault diagnosis, or programming work.
These events do not create identical requirements on every vehicle. The exact procedure must be checked for the model and system involved.
Calibration begins before the equipment is set up.
A damaged bracket, unresolved fault, or incorrect vehicle setup can prevent completion. Required mechanical and electronic conditions must be addressed first.
Identify the vehicle and affected systems
Review equipment, repair history, and applicable service information to establish the required procedures.
Check the prerequisites
Verify specified conditions, which may include mounting integrity, tire pressures, alignment, vehicle loading, and relevant fault status.
Perform the prescribed calibration
Use the appropriate equipment and follow the required stationary, driving, or combined procedure.
Review results and required verification
Confirm procedure status and complete the applicable checks and documentation. Investigate unsuccessful results before considering the work complete.
Scanning and calibration serve different purposes.
A diagnostic scan retrieves available information from supported control modules. Calibration performs a system-specific reference or learning procedure. Clearing fault codes does not substitute for calibration.
Likewise, calibration does not repair a damaged sensor, correct body misalignment, or replace every functional check required by the manufacturer.

Does every collision repair require ADAS calibration?
No. Requirements depend on the vehicle’s equipment, damage location, and repair operations. Manufacturer procedures determine whether calibration is required for the particular work.
Do I need calibration after windshield replacement?
Many vehicles with windshield-mounted cameras have calibration requirements associated with windshield replacement. The exact requirements must be checked for the vehicle and system.
Is a wheel alignment the same as ADAS calibration?
No. Alignment concerns wheel and suspension geometry. ADAS calibration concerns specified sensor or camera references. Some calibration procedures require correct alignment as a prerequisite.
Why might a calibration fail to complete?
Possible causes include unresolved faults, damaged attachments, incorrect setup, unmet vehicle prerequisites, or unsuitable driving or environmental conditions. The cause must be investigated.
Can I assume the system works because there is no warning?
No. The absence of a warning does not establish that required procedures have been completed. Repair requirements should be determined from the applicable service information.
How much does ADAS calibration cost?
Cost depends on the vehicle, number of affected systems, procedure type, setup, and prerequisite work. Provide your vehicle details and repair information so the required scope can be evaluated.
How long does calibration take?
Timing varies by procedure and vehicle condition. Dynamic procedures may also depend on suitable roads and weather. Additional time may be needed if faults or setup issues prevent completion.
What information should I provide when requesting service?
Share the vehicle’s year, make, model, and VIN, along with recent repair details, warning messages, and any scan or calibration reports you already have.
