The Differences Between Scanning and Calibration
I-CAR · May 10, 2018
Summary
This article clarifies the distinct differences between vehicle scanning (pre- and post-repair diagnostic trouble code identification and clearing) and ADAS calibration (aiming, module setup, or initialization required after part removal or repair). It warns that confusing these terms can lead to incomplete repairs, such as a dealership performing a simple scan when a full sensor calibration was actually required.
What to do on the job
Clearly distinguish between scanning and calibration on repair orders, and provide sublet vendors or technicians with a detailed list of the specific OEM calibration procedures required for the vehicle.
How to use it
Use this document to justify separate line items for both scanning and calibration on estimates and supplements. It serves as authoritative industry proof that a post-repair scan does not satisfy or include the necessary calibration/initialization steps required for ADAS sensors, preventing insurers from combining or denying these distinct operations.
