AV-SCANNER / Service function guides / Driver assistance and hybrid
This guide covers the complete radar sensor calibration procedure required after bumper repairs on adaptive cruise control systems, aimed at working mechanics and experienced DIYers who already understand basic vehicle electronics. It explains how millimeter-wave radar measures distance and angle, when calibration is mandatory, how to prepare the bay and vehicle, and the full step-by-step process from pre-scan to post-scan verification. Readers will be able to perform a static or dynamic calibration correctly, diagnose common failures such as blocked targets or misaligned brackets, and confirm the system meets factory tolerances before returning the vehicle to the road.
Guidance is general and covers many makes. Exact procedures and values vary by model, so confirm them in the factory service information for your vehicle.
