    MANUALLY CHANGE BEAM AXIS OF MILLIMETER WAVE RADAR SENSOR ASSEMBLY (for Mono Camera Type)

    Note:

    • Manually change the beam axis when error code 1 (no target abnormality) or 2 (target distance abnormality) or 3 (Plural targets abnormality) or 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 front bumper assembly.

    Tip:

    The millimeter wave radar sensor assembly is fixed to the front bumper assembly. If the installation position of the front bumper assembly is misaligned, the beam axis will also be misaligned. Therefore, when the front bumper assembly is deformed, even if the millimeter wave radar sensor assembly beam axis is manually changed or the millimeter wave radar sensor assembly is replaced, the millimeter wave radar sensor assembly beam axis adjustment may not complete.

      Note:

      The manual axis switching mechanism may get damaged if a torque higher than the above is applied.

      If the manual axis switching mechanism is damaged, replace the No. 1 millimeter wave radar sensor bracket.

      Tip:

      • Make sure to set the beam axis to the most upward or downward position.

      • Manually change the beam axis to the position *b (most downward position) when error code 12 (radar axis aiming failure upward) is displayed.

      • Manually change the beam axis to the position *c (most upward position) when error code 13 (radar axis aiming failure downward) is displayed.
