Per the May 2019 Post-Collision Diagnostic Scan and Calibration Requirements for Honda and Acura Vehicles position statement: “It is the position of American Honda that all vehicles* involved in a collision* must have the following minimum diagnostic scans, inspections, and/or calibrations done to avoid improper repair:

• A preliminary diagnostic scan during the repair estimation phase to determine what diagnostic trouble codes (DTCs) may be present, so proper repairs may be included. (See “Background on Scan Requirements” below for more information.
• A post-repair diagnostic scan to confirm that no DTCs remain.
• Any repair that requires disconnection of electrical components in order to perform the repair will require a post-repair diagnostic scan to confirm if the component is reconnected properly and functioning.
• Damage that requires the replacement of body parts will always require a post-repair diagnostic scan.
• Some safety and driver assistive systems will require inspections, calibration, and/or aiming after collision or other body repairs. See “Inspection/Calibration/Aiming Requirements” on page 2 for additional information.”

The position statement the identifies a collision as “damage that exceeds minor outer panel cosmetic distortion.”

Information on advanced driver assistance systems (ADAS) is included in the statement. You will find lists of different systems and procedures that will require calibration. Honda/Acura also added that, “In addition, these driver assistive systems often will not display DTCs during a vehicle scan unless there is damage to the applicable system, so aiming and/or calibration may be required. Refer to the published procedures on aiming and calibration in the appropriate service information available on ServiceExpress by searching the keyword Aiming.”
