How To Use This Service Information .

NOTE:
  • Before you troubleshoot, review the How to Troubleshoot - Refer to: How to Troubleshoot the Adaptive Cruise Control (ACC) (2019 2020 2021)  or How to Troubleshoot the Adaptive Cruise Control (ACC) (2022 2023) .
  • Before you troubleshoot, make sure all the tire pressures are correct, and remove all the cargo from the vehicle.
  • This DTC is recorded if the beam axis of the millimeter wave radar gets out of alignment as follows while the vehicle is driving:
    • Vertical direction: 3.0 degrees or more
    • Horizontal direction: 2.5 degrees or more
  • If this DTC is recorded, the following is suspected:
    • Change in the vehicle ride height caused by an overload or the vehicle being towed.
    • 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.
    • Altered suspension
    • 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.
  • The functions of the integrated driver support system that will be temporarily canceled when this DTC is recorded can be confirmed with the DTC troubleshooting index - Refer to: Driving Support DTC Troubleshooting Index (2019 2020 2021)  or Driving Support DTC Troubleshooting Index (2022 2023) .
