  3. MANUALLY CHANGE BEAM AXIS OF MILLIMETER WAVE RADAR SENSOR ASSEMBLY

    Note


    • Manually change the beam axis when error code 1 (no target abnormality), error code 2 (target distance abnormality), error code 3 (plural targets abnormality), error code 12 (radar axis aiming failure upward) or 13 (radar axis aiming failure downward) is displayed when the target is correctly set.

    • If the beam axis change mechanism is in the most upward or downward position, check for DTCs.

    • If no DTCs are output, repair or correctly install the radiator grill and front bumper cover.

    Tech Tips

    The millimeter wave radar sensor assembly is installed to the radiator grille. If the radiator grille is misaligned, the beam axis will be misaligned.For this reason, if the radiator grille is deformed, etc. and the millimeter wave radar sensor assembly is replaced or its beam axis is changed manually without repairing the deformation, the beam axis alignment may not be successfully completed.


    1. Remove the upper radiator support seal.
