    • Vertical direction: 3.0 degrees or more
    • Horizontal direction: 2.5 degrees or more

    • The beam axis of the millimeter wave radar is out of alignment due to improper installation.
    • The millimeter wave radar assembly or subassembly is deformed by a minor collision or strong impact.
    • The beam axis of the millimeter wave radar is out of alignment due to abnormal wheel alignment, abnormal tire pressure, etc.

    • When it is snowing, the radio waves transmitted and received by the millimeter wave radar may be refracted by the snow or ice attached around the millimeter wave radar such as the front grille, and are detected as a misalignment.
  • If this DTC is recorded, the integrated drive support system temporarily cancels its control to prevent excessive operation or malfunction.
  • Even when this DTC is recorded, the vehicle returns to normal if the misalignment of the detection axis of the millimeter wave radar is 1.5 degrees or less.
